In low-voltage, high-current application scenarios such as switch-mode regulators, DC-DC converters, motor drives, and portable power systems, TOSHIBA's TPH6R003NL,LQ(S), with its high-speed switching capability, low gate charge, and low on-resistance, has been a preferred choice for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces growing pain points: unpredictable lead times (often extending to months), procurement costs vulnerable to currency fluctuations, and delayed technical support. These challenges severely impact production schedules and cost control for downstream companies. Under these industry demands, domestic substitution has evolved from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, and enhance competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBGQA1305 N-channel power MOSFET based on independent R&D. This product is precisely aligned with the TPH6R003NL,LQ(S), offering core advantages of parameter enhancements, technological parity, and full package compatibility. It serves as a direct drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally attuned solution for various low-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance for Demanding Conditions.
Tailored as a domestic alternative to the TPH6R003NL,LQ(S), the VBGQA1305 achieves significant improvements in key electrical parameters, providing robust performance guarantees for high-current applications:
Firstly, the continuous drain current is increased to 45A, substantially surpassing the original model's 38A—an 18.4% enhancement in current-carrying capacity. This enables effortless handling of higher power loads, whether upgrading existing equipment or improving system stability at similar power levels.
Secondly, the on-state resistance is optimized for lower conduction losses. While the original model offers 6.8mΩ at 4.5V gate drive, the VBGQA1305 achieves an ultra-low 4.4mΩ at 10V gate drive, reducing conduction losses significantly. This contributes to higher overall efficiency and reduced heat generation, particularly in high-frequency switching applications, easing thermal design pressures.
Thirdly, the device supports a ±20V gate-source voltage, offering stronger gate ESD protection and noise immunity, preventing unintended turn-on in complex electromagnetic environments. The 1.7V gate threshold voltage ensures reliable switching and compatibility with mainstream driver ICs, requiring no adjustments to drive circuits and lowering substitution barriers.
Additionally, the VBGQA1305 features low leakage current and enhanced mode operation, matching the original model's reliability while providing performance headroom for more demanding scenarios.
Enhanced with Advanced SGT Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the TPH6R003NL,LQ(S) lies in its high-speed switching and low gate charge. The VBGQA1305 employs advanced Shielded Gate Trench (SGT) technology, building upon the original model's switching characteristics while optimizing device reliability. Through optimized structural design, it achieves low gate charge and fast switching speeds, minimizing switching losses and improving dv/dt tolerance. The device undergoes rigorous pre-shipment testing, including 100% avalanche and high-voltage screening, ensuring excellent performance under transient surges. With an operating temperature range of -55°C to 150°C, it adapts to harsh environments like industrial high-temperature settings. Having passed long-term reliability tests such as 1000-hour high-temperature/high-humidity aging, its failure rate is well below industry averages, providing solid assurance for critical applications like automotive systems, industrial controls, and consumer electronics.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, domestic substitution concerns often revolve around R&D investment and time costs. The VBGQA1305 addresses this through its package design. The device uses a DFN8(5x6) package, which is fully compatible with the TPH6R003NL,LQ(S) in pinout, pin spacing, and dimensions. Engineers need not modify PCB layouts or thermal designs, achieving seamless "plug-and-play" replacement. This compatibility reduces verification time to 1-2 days, eliminates PCB revision costs, and avoids re-certification hurdles, shortening supply chain cycles and enabling rapid market response.
