Product details

60V / 28A N-channel switch in a TO-220

The IRFZ34E is listed as Obsolete. If you have an existing BOM that calls out this exact order code, you're looking at the surplus and broker market to fill the line. The 60 V / 28 A / TO-220 footprint is a common one, though — a cross-reference search against other N-channel TO-220 MOSFETs in the same voltage and current class is the practical next step for a redesign or a last-time-buy bridge.

Sourcing the IRFZ34E today

Because the IRFZ34E is obsolete, standard distributor stock is depleted. If you're filling a repair, a legacy production run, or a prototype that needs this exact code, send an RFQ. For new designs, plan on qualifying a current-production N-channel MOSFET in the same TO-220 footprint.
