This is the official warning: the manufacturer will not support new design-ins, and a last-time-buy window may already be closing or closed. For existing production, the part remains available through independent distribution, but any new BOM should target the recommended successor. No stock or lead-time number can be guaranteed here; the RFQ is the only reliable path. At moderate switching frequencies (50–100 kHz), the 60 nC Qg is manageable with a standard totem-pole driver; above 200 kHz the gate-drive loss starts cutting into efficiency. The 4 V maximum threshold at 250 µA means a 5 V logic-level gate drive will turn the device on, but the 10 V drive voltage is needed to reach the minimum Rds(on) — a 5 V drive leaves the on-resistance roughly doubled, as the Rds(on) is specified at 10 V only.","metaTitle":"IRFZ44ESTRLPBF N-Channel MOSFET, 60V, 48A, D2PAK","metaDescription":"Infineon IRFZ44ESTRLPBF N-channel HEXFET® MOSFET, 60V Vdss, 48A Id, 23mΩ Rds(on) at 10V.
