Product details

600 V, 36 A N-channel in a TO-220 — what you are getting

The TO-220-3 through-hole package fits standard heatsink mounting and is field-serviceable — no hot-air station needed, just a screwdriver and a thermal pad.

At 80 mOhm max at 10 V gate drive, the conduction loss is low for a 600 V device, but the gate charge of 53.5 nC at 10 V means the driver needs to source and sink that charge per switching cycle. In a hard-switched converter at 100 kHz, the gate-drive loss is manageable with a standard totem-pole driver; at higher frequencies, budget for a driver with >1 A peak current to keep switching edges clean.

Temperature range and what it buys you

Package and mounting — field-swap friendly

TO-220-3 through-hole. Three leads, a metal tab, and a mounting hole. You can swap this on site with a screwdriver and a dab of thermal compound — no reflow oven, no hot air. The tab is the drain, so the heatsink needs isolation if the chassis is grounded.

Frequently asked questions

What is the Rds(on) of STP46N60M6?

The maximum on-resistance is 80 mOhm at 18 A drain current with 10 V gate drive.

What is the drain current rating of STP46N60M6?

Continuous drain current is 36 A at 25°C case temperature.

What is the closest pin-compatible alternative to STP46N60M6?

The STP46N60M6 is part of ST's MDmesh M6 family. A direct pin-compatible alternative would be another TO-220 N-channel MOSFET with similar voltage and current ratings, such as the STP46N60M2 from the earlier M2 series, but verify the gate charge and Rds(on) differences for your switching frequency.
