In high-voltage application scenarios such as switch-mode regulators, TOSHIBA's TK560A65Y,S4X(S), with its super junction DTMOS structure, low on-resistance, and easy gate control, has been a significant choice for engineers worldwide. However, against the backdrop of global supply chain disruptions and trade frictions, this imported component exposes pain points: unstable lead times, procurement costs affected by exchange rates, and lagging technical support, which constrain production schedules and cost control. Given this, domestic substitution has transitioned from an "option" to a "necessity," becoming critical for ensuring supply chain security and enhancing competitiveness.
VBsemi, with years of expertise in power semiconductors, launches the VBM165R07S N-channel power MOSFET based on independent R&D. This product precisely对标es the TK560A65Y,S4X(S), offering core advantages of parameter parity, technological equivalence, and full package compatibility. It serves as a direct replacement without circuit modifications, providing a stable, cost-effective, and locally attuned solution for high-voltage electronic systems.
Core Parameter Parity with Enhanced Reliability, Adapting to Demanding Conditions.
Tailored as a domestic alternative, the VBM165R07S achieves key electrical parameter matching while offering improved robustness:
First, the drain-source voltage is 650V, equal to the original, ensuring sufficient safety margin in environments with voltage fluctuations and transient overvoltage risks.
Second, the continuous drain current is 7A, matching the original, supporting high-power circuit designs and operational stability.
Third, the on-state resistance is 700mΩ (@10V gate drive), optimized through advanced SJ_Multi-EPI technology to reduce switching losses and thermal generation, enhancing overall efficiency in high-frequency applications.
Additionally, the VBM165R07S supports a ±30V gate-source voltage, providing stronger gate ESD and noise immunity, preventing unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage balances driving convenience and switching reliability, perfectly matching mainstream driver ICs without drive circuit adjustments, lowering the substitution barrier.
Advanced SJ_Multi-EPI Technology, Reliability and Stability Upgraded.
The TK560A65Y,S4X(S) leverages super junction DTMOS for low on-resistance. The VBM165R07S employs SJ_Multi-EPI technology, building on excellent switching characteristics while optimizing reliability. The device undergoes 100% avalanche testing and high-voltage screening, exhibiting excellent single-pulse avalanche energy performance, reducing damage risks from energy surges. Through optimized intrinsic capacitance design, it reduces charge/discharge losses and elevates dv/dt tolerance, ensuring stable operation under high-frequency switching and fast transients. The operating temperature range of -55°C to 150°C adapts to harsh conditions like industrial high-temperature environments. Having passed 1000-hour high-temperature/high-humidity aging tests and long-term reliability verification, its failure rate is below industry average, providing solid assurance for critical fields such as industrial control and power supplies.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement.
For downstream enterprises, the VBM165R07S addresses replacement costs through package design. It uses a TO-220 package, identical to the TK560A65Y,S4X(S) in pinout, dimensions, and heatsink structure. Engineers need not modify PCB layout or thermal design, achieving seamless replacement. This compatibility reduces verification time to 1-2 days, avoids PCB revision costs, and shortens the supply chain cycle, helping enterprises quickly upgrade imported components.
Local Strength Assurance, Dual Peace of Mind for Supply Chain and Support.
Compared to imported components, VBsemi leverages China's semiconductor industry chain, with production bases in Jiangsu and Guangdong, enabling stable mass production. Lead times are compressed to within 2 weeks, with emergency orders for 72-hour delivery, mitigating risks from supply chain volatility and geopolitics.
