In various high-efficiency DC-DC conversion and switching regulator applications, TOSHIBA's TPH7R006PL,L1Q, with its high-speed switching capability, low gate charge, low output charge, and low on-resistance, has long been a preferred choice for engineers worldwide. However, against the backdrop of global supply chain disruptions and frequent trade frictions in the post-pandemic era, this imported component has exposed pain points such as unstable lead times, cost volatility due to exchange rate fluctuations, and lagging technical support, severely constraining production schedules and cost control for downstream enterprises. Given this industry demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for ensuring supply chain security and enhancing core competitiveness. VBsemi, with deep expertise in power semiconductors, introduces the VBQA1615 N-channel MOSFET based on independent R&D. This product precisely aligns with the TPH7R006PL,L1Q, offering core advantages of parameter matching, technological parity, and full package compatibility. It serves as a direct replacement without circuit modifications, providing a stable, cost-effective, and locally attuned solution for high-efficiency electronic systems.
Comprehensive Parameter Matching and Enhancements for Superior Performance.
Tailored as a domestic alternative to TPH7R006PL,L1Q, the VBQA1615 achieves key electrical parameter improvements, ensuring robust performance in demanding applications:
Firstly, the drain-source voltage is maintained at 60V, matching the original model, guaranteeing compatibility in low-voltage circuits and safeguarding against overvoltage risks.
Secondly, the continuous drain current is 50A, offering substantial current-carrying capability for most DC-DC converter designs, while the on-state resistance is as low as 10mΩ (@10V gate drive), superior to the original's 13.5mΩ (@4.5V,10A)—this reduction significantly lowers conduction losses, improves overall efficiency, and minimizes heat generation in high-frequency switching scenarios.
Thirdly, the gate threshold voltage is 2.5V, within the range of TPH7R006PL,L1Q's 1.5-2.5V, ensuring easy drive compatibility with mainstream driver ICs. Additionally, the VBQA1615 supports a ±20V gate-source voltage, enhancing gate ESD and noise immunity, effectively preventing unintended turn-on in complex electromagnetic environments. With low leakage current and enhanced mode design, it delivers reliable switching performance for efficiency-critical applications.
Advanced Trench Technology for Enhanced Reliability and Switching Performance.
The core advantage of TPH7R006PL,L1Q lies in its high-speed switching and low charge characteristics. The VBQA1615 employs advanced Trench technology, building upon the original's strengths while optimizing device reliability. Through optimized intrinsic capacitance design, it achieves low gate charge and output charge comparable to the original, reducing switching losses and ensuring fast transient response—ideal for high-frequency DC-DC converters and switching regulators. The device undergoes rigorous pre-shipment testing, including avalanche energy and high-voltage screening, with an operating temperature range of -55°C to 150°C, adapting to harsh industrial environments. Having passed long-term reliability verifications such as high-temperature/high-humidity aging tests, its failure rate is well below industry averages, providing solid assurance for continuous operation in critical fields like telecom power, automotive electronics, and portable devices.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, a core concern in domestic substitution is the R&D investment and time cost. The VBQA1615 addresses this through its package design. The device uses a DFN8(5X6) package, identical to the TPH7R006PL,L1Q's package in pinout, dimensions, and thermal characteristics. Engineers can directly replace the original component without any PCB layout modifications or thermal system adjustments, achieving "plug-and-play" convenience. This high compatibility reduces substitution verification time to 1-2 days, eliminates costs from PCB revisions and mold adjustments, and avoids re-certification needs, effectively shortening the supply chain cycle and helping enterprises quickly seize market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components with unstable supply chains affected by international logistics and trade policies, VBsemi leverages China's robust semiconductor industry chain, with modern production bases in Jiangsu and Guangdong, enabling full-process R&D and stable mass production of VBQA1615. Current lead times are compressed to within 2 weeks, with emergency orders supporting 72-hour rapid delivery, mitigating risks from supply chain volatility and geopolitics.
