In various low-voltage, compact application scenarios such as portable electronic devices, battery-powered systems, low-voltage switch-mode power supplies, DC-DC converters, and load switches, TOSHIBA's SSM3K2615R,LF, with its low on-resistance and SOT23-3 package, has been a popular choice for engineers worldwide during design selection. However, against the backdrop of intensified global supply chain disruptions and frequent international trade frictions in the post-pandemic era, this imported component has gradually exposed numerous pain points: unstable lead times, procurement costs susceptible to exchange rate fluctuations, and lagging technical support responses. These issues severely constrain downstream companies' production schedules and cost control. Given this industry demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, enhance efficiency, and improve core competitiveness.
VBsemi, with years of deep cultivation in the power semiconductor field, has launched the VB1695 N-channel MOSFET based on its independent R&D capabilities. This product precisely对标es the SSM3K2615R,LF, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without any modifications to the original circuit, providing a more stable, cost-effective, and locally attuned high-quality solution for various low-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the SSM3K2615R,LF, the VB1695 achieves across-the-board, leapfrog improvements in key electrical parameters, offering more robust performance guarantees for low-voltage applications:
Firstly, the drain-source voltage is maintained at 60V, matching the original model, ensuring compatibility in standard low-voltage circuits while providing a solid foundation for reliable operation.
Secondly, the continuous drain current is increased to 4A, significantly surpassing the original model's 2A—a 100% enhancement in current-carrying capability. This enables effortless adaptation to higher current designs, whether upgrading existing equipment for higher power or improving system stability at the same power level.
Thirdly, the on-state resistance is as low as 75mΩ (@10V gate drive), far superior to the SSM3K2615R,LF's 580mΩ (@3.3V, 0.5A). This drastic reduction in conduction losses directly contributes to improved system efficiency, reducing heat generation and lowering cooling requirements in space-constrained applications.
Additionally, the VB1695 supports a ±20V gate-source voltage, offering stronger gate ESD and noise immunity, effectively preventing unintended turn-on in noisy environments. The 1.7V gate threshold voltage design ensures easy driving with low-voltage logic, perfectly matching mainstream microcontrollers and driver ICs without requiring additional circuit adjustments, further lowering the barrier to substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the SSM3K2615R,LF lies in its low on-resistance and compact form factor. The VB1695 employs the industry-leading Trench gate process, building upon the excellent switching characteristics while optimizing device reliability across multiple dimensions. The device undergoes 100% electrical testing and rigorous screening before leaving the factory, exhibiting excellent thermal and electrical performance. It can easily handle current surges and fast switching in low-voltage applications, significantly reducing the risk of device failure. Through optimized intrinsic capacitance design, it reduces switching losses and enhances dv/dt tolerance, perfectly matching the application scenarios of the SSM3K2615R,LF. Even under harsh conditions like high-frequency switching and transient loads, it maintains stable operation and can be directly replaced without modifying the circuit topology. Furthermore, the VB1695 features a wide operating temperature range, capable of adapting to various complex working conditions such as consumer electronics and industrial controls. Having passed stringent reliability tests, its failure rate is far below the industry average, providing solid assurance for long-term, uninterrupted device operation—especially suitable for fields with reliability requirements like portable gadgets, automotive electronics, and power management systems.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern regarding domestic substitution is the R&D investment and time costs involved in the replacement process. The VB1695 fundamentally addresses this pain point through its package design. The device uses a SOT23-3 package, which is completely identical to the SSM3K2615R,LF's package in terms of pinout, pin spacing, and package dimensions. Engineers need not make any modifications to the original PCB layout or thermal design, achieving a "plug-and-play" convenient replacement. The advantages brought by this high degree of compatibility are evident: on one hand, it significantly reduces the time cost of substitution verification, eliminating the need for R&D teams to invest in circuit redesign—sample validation can typically be completed within 1-2 days. On the other hand, it avoids increased production costs from PCB revisions and mold adjustments while ensuring the original product's structural dimensions remain unchanged. This effectively shortens the supply chain cycle, helping enterprises quickly achieve the substitution and upgrade of imported components and seize market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to the unstable supply chain of imported components affected by multiple factors like international logistics and trade policies, VBsemi leverages China's well-established semiconductor industry chain, with modern production bases and R&D centers. This enables full-process independent R&D and stable mass production of the VB1695. Currently, the standard lead time for this model is compressed to within 2 weeks, with emergency orders enabling rapid delivery. This effectively mitigates various risks such as supply chain volatility and geopolitics, providing solid assurance for the smooth progress of enterprise production plans. Simultaneously, as a local brand, VBsemi boasts a professional technical support team offering "one-on-one" customized services: providing comprehensive technical documentation, including substitution verification reports, device datasheets, and application circuit references, as well as targeted selection advice based on specific customer scenarios.
