Hi everyone,
I’m working on a power electronics project and came across the PBL S4004Y-115 (NXP) transistor / power device. I’m considering using it in switching regulator or inverter stages, but I want to hear from folks with practical experience before I commit.
What I’m planning
Using it as a high-side switch or part of a synchronous buck / boost converter. In a design where voltages are moderate (50–100 V DC) and currents up to ~10 A. Considering discharge cycles, switching stresses, and thermal performance.
hhow does the PBL S4004Y-115 hold up in real switching circuits (efficiency, thermal stability)? Any layout or gate driver considerations you’d strongly recommend (like snubber circuits, gate resistor sizing, driver voltage) when using this part? In long-term use, what failure modes have you seen (overheating, avalanche, secondary breakdown)?
Thanks in advance for your insights,
Jordan
