The last-time-buy window has closed, so new production is no longer available from the factory. Sourcing now runs through independent distribution — surplus inventory, new-old-stock, or broker channels. If you are qualifying a replacement, the pin-compatible IRFZ34N (non-leaded variant) is the direct functional equivalent in the same HEXFET family, sharing the same 55 V / 29 A / 40 mΩ ratings and TO-262 footprint. For new designs, look at Infineon's current-generation 55 V automotive-grade MOSFETs in TO-262 or D²Pak — the IRFZ44 series successors with lower Rds(on) and improved switching performance. ## Through-hole TO-262 — thermal and layout notes The TO-262 package (I²Pak compatible, three long leads) is a through-hole power package with a metal tab that carries the drain. The 68 W power dissipation at case temperature assumes the tab is bolted to a heatsink with thermal interface material — without it, the 3.8 W ambient rating is the limit. The 10 V gate drive voltage is specified for minimum Rds(on); driving with 5 V logic will roughly double the on-resistance, so use a dedicated gate driver or a 10 V rail.","metaTitle":"IRFZ34NL HEXFET N-Channel MOSFET, 55V 29A TO-262, Obsolete","metaDescription":"IRFZ34NL N-channel HEXFET MOSFET: 55V Vdss, 29A Id, 40mΩ Rds(on) at 10V, TO-262 package.
