Without adequate copper, the 3.8 W ambient-air dissipation limit applies, which constrains continuous current to well below 29 A.","metaTitle":"IRFZ34NSPBF N-Channel MOSFET, 55V 29A HEXFET, D2PAK","metaDescription":"IRFZ34NSPBF N-channel MOSFET from Infineon's HEXFET series. 55V Vdss, 29A Id, 40mOhm Rds(on) at 10V.
