Product details

650 V N-channel in a full-pack through-hole package

It is housed in a TO-3P-3 Full Pack (TO-3PF) through-hole package, which provides full isolation from the heatsink — no insulating pad or washer is needed, simplifying mechanical assembly and improving thermal transfer to the heatsink.

Conduction and switching losses — what the numbers mean

The 143 nC total gate charge at 10 V tells the gate driver how much current it must source to hit the target switching frequency — a 143 nC gate switched at 50 kHz draws about 7.2 mA average from the driver, well within the capability of most half-bridge gate-driver ICs. The device is specified for a 10 V drive for minimum Rds(on), which is standard for super-junction MOSFETs.

Package and mounting — the full-pack advantage

The TO-3PF (TO-3P Full Pack) package has a fully isolated backside, so the device can be bolted directly to a grounded or shared heatsink without an insulating pad. The through-hole leads handle the 58 A continuous drain current and the 79 W maximum power dissipation — the limiting factor is the heatsink's thermal resistance, not the package itself.

Frequently asked questions

What is the equivalent of STFW69N65M5?

The MDmesh™ V series includes other voltage and current variants, but a direct functional replacement would require matching the 650 V Vdss, 58 A Id, 45 mOhm Rds(on), and TO-3PF package. Check the ST product portfolio for other MDmesh V parts in the same package.
