Technical details

200 V drain, 18 A continuous — headroom for a 48 V bus

That 200 V rating gives you a solid 4× margin on a 48 V motor drive bus — the kind of headroom that keeps the part alive during regeneration spikes or a stalled motor.

100 mOhm on-resistance — the conduction-loss number

At 11 A the conduction loss is about 12 W, which is well within the 100 W package limit at the case if you bolt it to a decent heatsink.

Through-hole TO-220 — field-swappable, no hot air needed

The TO-220AB through-hole package is a field-service favourite. You can swap it with a soldering iron and a desoldering pump — no hot-air station, no preheater. The tab is the drain, so orientation is obvious once the part is in your hand.

Active lifecycle, ROHS3 — no obsolescence clock

No last-time-buy notice, no end-of-life date on the horizon.
