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 ## Gate-drive and threshold considerations 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.

Both are P-channel 55 V, 19 A MOSFETs in TO-220 with similar Rds(on) and gate charge. The AUIRF9Z34N-INF adds the AEC-Q101 automotive reliability screening and is typically used in automotive and high-reliability applications.
