Product details

60 V, 57 A N-channel power switch — TO-220-3 tab-mount

The IRFZ44VZPBF: It comes in a TO-220-3 through-hole package (TO-220AB) with the large copper tab that bolts to a heatsink or chassis for thermal management.

Gate charge and switching — driver budget

Total gate charge is 65 nC at 10 V. Input capacitance is 1690 pF at 25 V drain-source. Recommended drive voltage for lowest Rds(on) is 10 V. Maximum gate-source voltage is ±20 V.

Maximum junction temperature is 175°C.

NRND status — what it means for procurement

The IRFZ44VZPBF carries a Not Recommended for New Designs (NRND) lifecycle status. Existing BOM lines should be qualified against a pin-compatible replacement before the supply window closes.

Frequently asked questions

Is IRFZ44VZPBF obsolete?

It is still available through independent distribution but is not intended for new production builds. Plan a replacement qualification before the supply window closes.
