The IRLB8743PBF is a single N-Channel MOSFET utilizing HEXFET technology. It features a drain-to-source breakdown voltage of 30V and a continuous drain current of 150A at 25°C (silicon limited) or 110A (package limited). At 100°C, the current rating is 78A. The device offers ultra-low on-resistance: 3.2mOhm maximum at 10V gate voltage and 40A drain current, and 4.2mOhm maximum at 4.5V. Total gate charge is 54nC maximum at 4.5V, with typical input capacitance of 5110pF at 15V.
Power dissipation is rated at 140W at 25°C case temperature, and the junction temperature range is -55°C to +175°C. The MOSFET is housed in a through-hole TO-220-3 package (TO-220AB) with 3 pins, suitable for mounting on heatsinks. Thermal resistance junction-to-case is 1.11°C/W maximum.
This part is optimized for high-frequency switching applications such as UPS/inverter power stages, synchronous buck converters for computer processors, and isolated DC-DC converters with synchronous rectification for telecom and industrial use. The device is lead-free as verified by the datasheet.
