In modern compact electronic designs such as load switches, motor drives, portable devices, and battery management systems, TOSHIBA's SSM3K2615R,LXGF, with its AEC-Q101 qualification, 3.3V gate drive capability, and low on-resistance, has been a popular choice for space-constrained, efficiency-critical applications. However, in today's dynamic global market, reliance on imported components like this often brings challenges: extended lead times, vulnerability to supply chain disruptions, and limited local technical support. These factors can delay product development and increase operational risks. In this context, domestic substitution emerges as a strategic imperative, offering a pathway to secure supply chains, reduce costs, and accelerate time-to-market.
Leveraging its expertise in power semiconductor innovation, VBsemi introduces the VB1695 N-channel MOSFET, a purpose-designed domestic alternative to the SSM3K2615R,LXGF. This device delivers superior electrical parameters, robust performance, and full package compatibility, enabling a direct, drop-in replacement that requires no circuit modifications. It provides a more reliable, cost-effective, and readily available solution for next-generation low-voltage applications.
Superior Parameters for Higher Performance and Greater Design Margin
Tailored to replace the SSM3K2615R,LXGF, the VB1695 achieves significant enhancements across key specifications, providing engineers with greater headroom and efficiency:
First, the continuous drain current is rated at 4A, doubling the original part's 2A capability. This 100% increase in current handling allows for more robust load switching and motor driving, supporting higher power demands or improving reliability within existing current limits.
Second, the on-state resistance is dramatically reduced. With RDS(ON) as low as 75mΩ at VGS=10V, the VB1695 offers drastically lower conduction loss compared to the 580mΩ (at 3.3V) of the SSM3K2615R,LXGF. This translates directly into higher system efficiency, reduced heat generation, and potential for longer battery life in portable applications.
Third, the device supports an extended gate-source voltage range of ±20V, enhancing robustness against voltage spikes and noise in challenging electrical environments. The 1.7V gate threshold voltage ensures easy and reliable switching compatibility with low-voltage microcontroller outputs and common driver ICs, simplifying design integration.
Advanced Trench Technology for Reliable Operation
The SSM3K2615R,LXGF leverages Toshiba's process for low RDS(ON). The VB1695 utilizes an advanced Trench MOSFET technology, optimizing cell density to achieve an excellent balance of low on-resistance and switching performance. This technology ensures minimal switching losses and stable operation under high-frequency conditions. The device is designed for high reliability and is suitable for demanding automotive and industrial environments, matching the quality benchmarks set by the original part.
Seamless Drop-In Replacement with SOT23-3 Package
A major concern in component substitution is redesign effort. The VB1695 eliminates this hurdle through complete package compatibility. It is offered in the industry-standard SOT23-3 package, featuring identical pinout, footprint, and dimensions as the SSM3K2615R,LXGF. Engineers can directly replace the existing component on the PCB without any layout changes or thermal redesign, enabling a true "plug-and-play" experience. This compatibility drastically cuts qualification time, avoids costly PCB re-spins, and accelerates product revision cycles, allowing for swift and risk-free adoption.
Local Supply Chain Assurance and Expert Technical Support
Unlike imported components subject to logistical and geopolitical uncertainties, the VB1695 benefits from VBsemi's localized manufacturing and supply chain within China. This ensures stable production capacity, shorter lead times (typically within weeks), and protection against international trade volatility. Furthermore, VBsemi provides responsive, local technical support, offering comprehensive documentation, application guidance, and rapid troubleshooting. This direct support model resolves the common pain points of slow response and communication barriers associated with overseas suppliers, making the design and production process smoother and more efficient.
From load switches and motor drives in consumer electronics to power management modules in IoT devices and automotive systems, the VB1695 stands out as the premier domestic alternative to the TOSHIBA SSM3K2615R,LXGF. With its compelling advantages of higher current capability, significantly lower RDS(ON), full package compatibility, secured supply, and localized service, it has already been successfully adopted by numerous customers. Choosing the VB1695 is more than a component swap—it is a strategic upgrade toward supply chain resilience, improved product performance, and enhanced market competitiveness.
