The device is qualified to AEC-Q101, making it suitable for under-hood automotive electronics, industrial motor drives, battery management, and power distribution where a high-side P-channel switch simplifies the gate-drive circuit. ## Thermal and switching margins Power dissipation is rated at 68 W at case temperature, with the TO-220AB package relying on a good thermal interface to the heatsink — the tab is the drain, so the usual mica insulator and thermal compound apply. Gate charge is 35 nC at 10 V, which keeps switching losses manageable for PWM frequencies up to a few tens of kHz with a standard gate-driver IC. ## Gate-drive and threshold considerations The maximum gate threshold voltage is 4 V at 250 µA drain current, and the recommended drive voltage for the rated Rds(on) is 10 V. Input capacitance is 620 pF at 25 V drain-source, so the gate-drive source impedance should be low enough to avoid slow turn-on edges that push switching loss higher.","metaTitle":"AUIRF9Z34N-INF P-Channel MOSFET, 55V 19A TO-220, AEC-Q101","metaDescription":"Infineon AUIRF9Z34N-INF automotive P-Channel HEXFET MOSFET, 55V Vdss, 19A Id, 100mOhm Rds(on) at 10V.
