Product details

20 V N-Channel HEXFET — low-voltage load switch for tight boards

Its 22 mOhm maximum on-resistance at 4.5 V gate drive means it handles 8.7 A continuous drain current with manageable conduction loss — useful for load switching, DC/DC OR-ing, or battery-protection cutoffs in portable equipment. The drive voltage range (2.7 V minimum for full enhancement) lets it operate from 3.3 V logic rails without a gate-drive booster, though the 48 nC gate charge still needs a driver capable of sourcing that peak current for fast edges.

Lifecycle — obsolete, last-time-buy closed

Procurement must source through independent distribution — surplus inventory, NOS (new old stock), or broker channels.
