Product details

30 V, 80 A N-channel — STripFET™ II in a TO-220

STMicroelectronics has designated the STP80NF03L as obsolete. No official replacement part number has been published by ST; any substitute should be validated for pin-compatibility and parametric fit in the target circuit.

Key ratings for the switching design

The 30 V Vdss rating suits 12 V and 24 V power rails with margin, but is not suitable for 48 V or higher bus voltages. The 4.5 mOhm Rds(on) at 10 V gate drive is the headline figure for conduction loss calculations; at 4.5 V drive the on-resistance increases, so the 110 nC gate charge at 4.5 V confirms logic-level drive compatibility — a 5 V PWM signal from an MCU or gate driver can fully enhance the channel.

Frequently asked questions

What is the equivalent replacement for STP80NF03L?

STMicroelectronics has not published an official replacement part number for the STP80NF03L. Any substitute should be validated for pin-compatibility, 30 V Vdss, 80 A continuous drain rating, and 4.5 mOhm Rds(on) at 10 V gate drive in the TO-220 package.

Is STP80NF03L compatible with 5V gate drive?

Yes. The gate charge is specified at 4.5 V (110 nC max), and the drive voltage range includes 4.5 V as the minimum for achieving the rated Rds(on). A 5 V logic signal from an MCU or gate driver is sufficient to fully enhance the channel.

Can I use STP80NF03L in a 12V circuit?

Yes. The 30 V Vdss rating provides ample margin for a 12 V nominal rail, including transients. The 80 A continuous drain rating and 4.5 mOhm Rds(on) make it well suited for high-current 12 V switching applications.
