Product details

At the full 12 A continuous rating, conduction loss reaches about 14.4 W at 100 mOhm, which the 42.8 W package dissipation limit can handle with adequate thermal management — a heatsink pad or via array under the DPAK tab is expected.

10 nC gate charge — low drive burden for medium-frequency switching

The total gate charge is 10 nC at 5 V, which is modest for a 12 A rated device.

This part can be used in avionics, downhole instrumentation, or outdoor telecom equipment where ambient temperatures push beyond 85°C. The 175°C maximum junction is higher than the typical 150°C limit on many standard MOSFETs, giving extra headroom for high-current or high-ambient designs.

The STD12NF06LT4 is listed as obsolete. It is no longer manufactured by STMicroelectronics and is not available through the factory channel. Sourcing is through independent distribution — new-old-stock or surplus inventory.

Frequently asked questions

Where can I buy STD12NF06LT4 and how do I get a price?

STD12NF06LT4 is obsolete and not available from the manufacturer. We source it through independent distribution and can provide a quote on request. Submit an RFQ and we will confirm availability and current pricing.

What is the replacement for STD12NF06LT4?

STMicroelectronics has not published an official successor order code for the STD12NF06LT4. For a pin-compatible alternative, look for other N-channel DPAK MOSFETs in the 60 V, 12 A class from ST's current STripFET™ F7 or Power MOSFET families, or from suppliers such as Infineon (OptiMOS) or onsemi. Verify the gate threshold voltage and Rds(on) match your drive voltage.

What are the specifications of STD12NF06LT4?

It is in a DPAK surface-mount package and operates from -55°C to 175°C junction temperature.
