Application & Notes
BFX34 by STMicroelectronics is an N-channel power MOSFET rated at N/A / N/A, commonly used in DC-DC converters, motor drivers, power supplies, and battery protection circuits. The TO-205AD, TO-39-3 Metal Can package offers good thermal performance for SMT mounting. Key spec: Rds(on) max N/A. Select gate driver voltage carefully — logic-level variants exist for direct MCU drive.
