A single new MOSFET paired with an aged partner mismatches Qg and RDS(on), stressing both devices unevenly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Always check the gate driver IC when this MOSFET dies?\u003c\/strong\u003e\u003cbr\u003eA: Strongly recommended. Voltage spikes from a shorting MOSFET often take out the driver in the same event. Skipping the driver replacement is a common cause of repeat failure within hours.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: TO-247 mounting torque?\u003c\/strong\u003e\u003cbr\u003eA: Use the heat-sink manufacturer's torque spec.
