Product details

The STMicroelectronics STFI26N60M2 is a 600 V, 20 A N-channel power MOSFET from the MDmesh™ series, built on a planar technology that balances on-resistance and switching losses for hard-switching topologies.

Obsolete — sourcing reality and the replacement question

The STFI26N60M2 is listed as obsolete. That means STMicroelectronics has stopped production, and the only channel to source this part is the surplus / independent distribution market — new-old-stock or pulled inventory.

The TO-262-3 Full Pack (I2PAKFP, also called TO-281) is a through-hole package with a fully molded isolation layer — the metal tab is not electrically live, so no mica washer or sil-pad is needed when bolting to a heatsink. That saves a step in assembly and reduces thermal interface resistance, but the full-pack construction also limits power dissipation to 30 W at case temperature (Tc).

Frequently asked questions

Where can I buy STFI26N60M2?

STFI26N60M2 is obsolete and no longer in production.

Is STFI26N60M2 obsolete?

Yes, STFI26N60M2 is listed as obsolete by STMicroelectronics. Production has ceased, and the part is only available through surplus or broker channels.

What package is STFI26N60M2?

It comes in a TO-262-3 Full Pack (I2PAKFP) through-hole package, also known as the I2PAKFP or TO-281 supplier device package.
