In various high-current, high-efficiency application scenarios such as DC-DC converters, switching regulators, power management systems, server power supplies, and automotive electronics, Toshiba's TPHR8504PL,LQ(M1W, with its high-speed switching capability, low gate charge, and minimal output charge, has been a preferred choice for engineers globally. However, in the post-pandemic era marked by intensified global supply chain disruptions and trade uncertainties, this imported component faces growing challenges: unpredictable lead times, procurement costs vulnerable to currency fluctuations, and delayed technical support. These issues severely impact production schedules and cost efficiency for downstream enterprises. Against this backdrop, domestic substitution has evolved from an "option" to a "necessity," serving as a critical pathway for ensuring supply chain security, reducing costs, and enhancing core competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBGQA1400 N-channel MOSFET through independent R&D. This product is precisely tailored to replace the TPHR8504PL,LQ(M1W, offering core advantages of parameter enhancements, technological parity, and full package compatibility. It enables direct replacement without circuit modifications, delivering a more stable, cost-effective, and locally attuned solution for high-current electronic systems.
Comprehensive Parameter Advancement, Ample Performance Margins, Adapting to Demanding Conditions.
Designed as a domestic alternative to the TPHR8504PL,LQ(M1W, the VBGQA1400 achieves significant improvements in key electrical parameters, providing robust performance guarantees for high-current applications:
First, the continuous drain current is increased to 250A, substantially surpassing the original model's 150A—a 66.7% enhancement in current-carrying capacity. This allows effortless adaptation to higher-power designs, whether upgrading existing equipment or improving stability at similar power levels.
Second, the on-state resistance is as low as 0.8mΩ (@10V gate drive), comparable to or better than the TPHR8504PL,LQ(M1W's 0.85mΩ (@10V), with typical values offering excellent conduction loss reduction. This minimizes heat generation and improves overall system efficiency, particularly in high-frequency switching environments.
Third, the device supports a ±20V gate-source voltage, ensuring strong gate ESD protection and noise immunity, preventing unintended turn-on in complex electromagnetic conditions. The 2.5V gate threshold voltage balances drive convenience and switching reliability, seamlessly matching mainstream driver ICs without requiring circuit adjustments.
Additionally, the VBGQA1400 maintains a drain-source voltage of 40V, matching the original model, while offering enhanced performance margins for stable operation in fluctuating voltage scenarios.
Enhanced with Advanced SGT Technology, Reliability and Stability Inherited and Upgraded.
The TPHR8504PL,LQ(M1W excels in high-speed switching with low gate charge (QSW = 23 nC typical) and output charge (QSS = 85.4 nC typical). The VBGQA1400 employs advanced Shielded Gate Technology (SGT), optimizing switching characteristics and reliability. It features reduced gate and output charges, enabling faster switching speeds and lower losses in DC-DC converters and regulators. The device undergoes rigorous avalanche testing and high-current screening, ensuring excellent durability against energy surges. Through optimized internal capacitance design, it minimizes charge/discharge losses and enhances dv/dt tolerance, matching the TPHR8504PL,LQ(M1W's application scenarios. With an extended operating temperature range and proven reliability through high-temperature/high-humidity aging tests, it offers superior stability for critical applications like automotive systems, industrial controls, and data centers.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a key concern in domestic substitution is the R&D investment and time required. The VBGQA1400 addresses this through its package design. It utilizes a DFN8(5X6) package, fully compatible with the TPHR8504PL,LQ(M1W in pinout, dimensions, and thermal structure. Engineers can achieve "plug-and-play" replacement without modifying PCB layouts or thermal designs. This compatibility slashes verification time—sample validation typically completes within 1-2 days—and avoids costs from PCB revisions or retooling. It ensures unchanged product dimensions, eliminating re-certification needs and accelerating supply chain cycles for swift component upgrades.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components hampered by international logistics, trade policies, and exchange rate volatility, VBsemi leverages China's robust semiconductor industry chain, with modern production bases in Jiangsu and Guangdong. This enables full-process R&D and stable mass production of the VBGQA1400.
