Product details

Switching loss and gate drive — 204 nC Qg

Gate charge of 204 nC at 10 V is moderate for an 84 A MOSFET. A standard gate-driver IC can drive it without excessive cross-conduction.

Through-hole TO-247-3 — field-swappable, no hot-air station needed

The TO-247-3 through-hole package is a field-service favourite. Three leads, a mounting hole for a screw to the heatsink, and the tab is the drain — orientation is obvious. You can swap it on site with a soldering iron and a screwdriver; no hot-air station or reflow profile. The 450 W dissipation rating assumes the case is bolted to a heatsink with thermal compound; running it without one derates that number hard. The ±25 V maximum gate-source voltage is generous, but keep the gate drive within 10 V to stay in the low-Rds(on) region.

No last-time-buy or obsolescence risk for new designs. If you are freezing a BOM, this part is safe to qualify in — no PCN watch needed right now.

Frequently asked questions

What is the Rds(on) of STW88N65M5?

The maximum Rds(on) is 29 mOhm at a drain current of 42 A and a gate-source voltage of 10 V. This is the key spec for conduction loss calculations in high-current SMPS and PFC stages.

Is STW88N65M5 lead-free?

Yes, the STW88N65M5 is ROHS3 compliant, which covers lead-free requirements for most markets. No additional exemption documentation is typically needed.
