Product details

55 V, 30 A N-channel HEXFET — obsolete, but still specified

The Infineon IRLZ34NLPBF is a 55 V, 30 A N-channel HEXFET MOSFET in a through-hole TO-262 package (I²Pak with long leads).

Gate charge and drive voltage — low-side switching at 4 V logic

Gate charge is 25 nC at 5 V. Drive voltage range is 4 V to 10 V, with ±16 V Vgs(max).

Any stock available on the open market is new-old-stock or surplus — date codes will be from the last production run. For new designs, a current-production N-channel MOSFET in a TO-220 or TO-263 package with similar 55 V / 30 A ratings should be evaluated.

Frequently asked questions

What is the replacement for the IRLZ34NLPBF?

For a pin-compatible through-hole replacement, evaluate current-production N-channel MOSFETs in a TO-262 or TO-220 package with a 55 V Vdss, 30 A continuous drain rating, and a 35 mOhm or lower Rds(on) at 10 V. The IRFZ34N (TO-220) or AUIRFZ34N (automotive grade) are common functional equivalents, but verify the pinout and package fit for your board.
