Manufacturer: Infineon Technologies

Categories: FET, MOSFET Arrays

Quality Control: Learn More

Infineon Technologies HEXFET MOSFET array, part number IRF7343PBF, offers a complementary N-channel and P-channel configuration within an 8-SOIC package. This device features a Drain-Source Voltage (Vdss) of 55V, with continuous drain currents of 4.7A for the N-channel and 3.4A for the P-channel at 25°C. The N-channel MOSFET exhibits a maximum On-Resistance (Rds(on)) of 50mOhm at 4.7A and 10V, while the P-channel has a comparable Rds(on) under specified conditions. Gate charge is rated at 36nC maximum at 10V, with input capacitance (Ciss) at 740pF maximum at 25V. Rated for a maximum power dissipation of 2W, this device operates across a temperature range of -55°C to 150°C. The IRF7343PBF is commonly utilized in automotive, industrial, and power management applications requiring efficient switching and complementary MOSFET functionality.
