Product details

25 V, 80 A N-channel — the scorch-mark tells you it's a low-side switch

The STD95N2LH5: It comes in a DPAK (TO-252) surface-mount package — the same footprint as dozens of other 80 A-class parts, so a board swap is usually a direct solder-in.

That translates to about 7.2 W conduction loss at 40 A — well within the 70 W power dissipation rating, but the DPAK's thermal pad needs a decent copper pour on the PCB to keep the junction below 175°C. The 13.4 nC gate charge at 5 V means a standard 5 V GPIO or a simple gate driver can switch it at moderate frequencies without a dedicated high-current driver IC.

Frequently asked questions

What is the Rds(on) of STD95N2LH5?

At 5 V gate drive, the on-resistance is slightly higher but still within the same ballpark — the datasheet specifies the drive voltage range as 5 V to 10 V.

Is STD95N2LH5 a direct replacement for STD95N2LH3?

The STD95N2LH5 is from the same STripFET™ V family and shares the same DPAK package and 25 V / 80 A ratings as the STD95N2LH3. The Rds(on) and gate charge are very close, so it is a drop-in replacement in most designs. Confirm the gate drive voltage and switching frequency match your application.
