MOSFET N/P-CH 30V 4A/3A 8SOIC

Manufacturer: Infineon Technologies

Categories: FET, MOSFET Arrays

Quality Control: Learn More

Infineon Technologies HEXFET® AUIRFI7309QTR is a dual N-channel and P-channel MOSFET array designed for demanding automotive and industrial applications. This 30V device features a continuous drain current capability of 4A for the N-channel and 3A for the P-channel, with a maximum power dissipation of 1.4W. The AUIRFI7309QTR offers a low Rds(on) of 50mOhm at 2.4A and 10V, supporting efficient power switching. Its logic level gate feature simplifies drive requirements, and the input capacitance (Ciss) is 520pF at 15V, with a gate charge (Qg) of 25nC at 4.5V. The device operates across a temperature range of -55°C to 150°C and is supplied in an 8-SOIC package, presented on a tape and reel for automated assembly.
