Application & Notes
STK820 by STMicroelectronics is an N-channel power MOSFET rated at 25 V / N/A, commonly used in DC-DC converters, motor drivers, power supplies, and battery protection circuits. The PolarPak® package offers good thermal performance for SMT mounting. Key spec: Rds(on) max 7.3mOhm @ 10.5A, 10V. Select gate driver voltage carefully — logic-level variants exist for direct MCU drive.
