Overview
Description
- Voltage Rating: -55V (Drain-to-Source, VDS)
- Current Rating: -74A (Continuous Drain Current, ID)
- Low On-Resistance: 20mΩ (RDS(on)) at VGS = -10V
- Fast Switching: Suitable for motor control, power supplies, and DC-DC converters
- Package: TO-220AB (through-hole, easy to mount)
It operates with a gate threshold voltage (VGS(th)) of -2V to -4V, making it compatible with standard logic-level drivers. The IRF4905PBF is robust, with built-in avalanche protection, and is commonly used in battery management, inverters, and load switching.
For optimal performance, ensure proper heat dissipation (max junction temp: 175°C) and drive voltage (VGS ≤ ±20V).
