Single FETs, MOSFETs Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or surplus channels. Ensure that any sourced units are genuine and match the original Vishay/Siliconix specifications before integration into designs.

Single FETs, MOSFETs Selection Notes

Designers should consider this part only for legacy maintenance or non-critical prototyping due to its discontinued status. For new designs, evaluate modern equivalents from the same family or alternative manufacturers offering similar electrical characteristics and package compatibility to ensure long-term supply stability.

Single FETs, MOSFETs Part Context

The IRFR420 belongs to the IRFR series of power MOSFETs, which are widely recognized for their reliability in medium-power applications. Manufactured originally by International Rectifier and later Vishay Siliconix, this specific model represents an older generation of DPAK-packaged devices now superseded by newer iterations.
