It is rated for a drain-source voltage of 900 V and a continuous drain current of 1.6 A, with a power dissipation limit of 50 W. The hermetic package and through-hole mounting suit applications where reliability under thermal or mechanical stress is critical — military power supplies, avionics converters, or high-voltage industrial inverters where potting or conformal coating is standard. ## 900 V rating — what it means for the bus The 900 V drain-source breakdown voltage gives this MOSFET headroom on a nominal bus. The 1.6 A continuous current rating, paired with the 50 W dissipation limit, means it can handle moderate loads without oversized heatsinking, provided the switching frequency stays low enough to keep conduction losses dominant. The through-hole package allows bolt-down to a chassis or cold plate for thermal management. ## Lifecycle and sourcing No end-of-life notice or last-time-buy window is in effect. For BOM planning, this part can be qualified into a new design without near-term obsolescence risk.","metaTitle":"IRFAF20 N-Channel Hermetic HEXFET MOSFET, 900 V, 1.6 A","metaDescription":"IRFAF20 is an N-channel hermetic HEXFET MOSFET rated at 900 V, 1.6 A, 50 W.
