Product details

650 V N-channel in a DPAK — primary-side switching workhorse

That works out to about 10 W conduction loss at full current — the 85 W power dissipation rating gives you headroom, but the DPAK's thermal path to the board copper matters. Input capacitance is 620 pF at 100 V drain-source, which keeps the switching losses in check for hard-switched topologies. The 5 V threshold at 250 µA means the gate drive needs to swing to 10 V to get the rated Rds(on) — 5 V logic won't fully enhance it.

No last-time-buy notice, no end-of-life risk on the immediate horizon. For new designs, this is a safe call — no need to qualify a substitute yet.

Frequently asked questions

What is the closest pin-compatible alternative to STD11N65M5 in the same family?

Within the MDmesh V family, the STD11N65M5 shares the same DPAK footprint and 650 V rating as other STD11N65xx variants. The key difference is the on-resistance and current rating — check the specific Rds(on) and Id for your load before cross-referencing.

Is STD11N65M5 Pb-free and RoHS compliant?

Yes, it is ROHS3 compliant. No additional Pb-free statement is needed — the ROHS3 status covers the exemption categories.
