Product details

At full rated current, expect roughly I²R loss of 34² × 0.088 ≈ 102 W — that number lands squarely inside the 250 W maximum power dissipation, but only with a heatsink that keeps the case temperature under control. Input capacitance of 2500 pF at 100 V drain-source is typical for this die size. It influences the gate-drive power requirement and the turn-on delay — factor it into the driver's peak current and the gate-loop inductance budget.

The wide range also gives headroom for transient overloads without immediate derating.

The exposed metal tab is the drain — ensure electrical isolation from the heatsink unless the system topology allows a shared drain potential. The TO-220 form factor is a mature, widely socketed footprint for single-ended power stages.

Frequently asked questions

What is the closest pin-compatible alternative to the STP40N60M2?

Within the same MDmesh II Plus family, the STP40N60M2 is the 34 A, 88 mOhm variant. A higher-current sibling like the STP50N60M2 (50 A, lower Rds(on)) shares the same TO-220 footprint and gate-drive voltage, but the Rds(on) and current rating differ — verify thermal margin before substituting.
