Product details

The 150°C maximum junction allows headroom for self-heating in a compact DPAK footprint.

Supplied in Tape & Reel for automated assembly, the DPAK (TO-252) package has a metal tab on the top for heatsinking — the tab is the drain. The surface-mount footprint is standard for medium-power MOSFETs; the tab should be soldered to a copper pour on the PCB to spread heat.

Frequently asked questions

What is the STDLED524 Rds on at 2.2 A?

The maximum Rds(on) is 2.6 Ohm at 2.2 A drain current with 10 V gate drive. This is the spec to use for worst-case conduction loss calculations.
