Product details

The STD12NF06-1 is a 60 V, 12 A N-channel power MOSFET from STMicroelectronics' STripFET™ II series, built on a planar stripe technology that keeps gate charge low — 12 nC typical at 10 V — so the gate driver doesn't need to push much current for fast switching.

Through-hole I-PAK — mounting and thermal notes

The STD12NF06-1 comes in a TO-251-3 short-lead I-PAK package, a through-hole footprint that suits manual assembly or wave-solder lines. The exposed metal tab on the I-PAK carries the drain potential and is the primary thermal path — a copper pad on the PCB with a via stitch to an inner-plane copper pour pulls heat out of the junction.

Lifecycle status — obsolete, but still sourced

STMicroelectronics lists the STD12NF06-1 as obsolete. However, the part remains available through independent distribution channels, sourced from existing inventory and surplus stock.

Frequently asked questions

What is the direct replacement for STD12NF06-1?

STMicroelectronics has not published an official direct replacement for the STD12NF06-1. For a pin-compatible alternative in the same TO-251 I-PAK footprint, look for a 60 V N-channel MOSFET with similar Rds(on) and gate charge. Without an official cross-reference, the best approach is to compare datasheets for parts like the STD12NF06T4 or STD12NF06-1's sibling in the STripFET™ II family, but verify the pinout and thermal performance against your design.

What is the Rds(on) and current rating of STD12NF06-1?

Its continuous drain current rating is 12 A at 25°C case temperature, and the drain-source breakdown voltage is 60 V.
