IRF7309PBF

The IRF7309PBF is a complementary MOSFET array from Infineon Technologies, combining N-channel and P-channel MOSFETs in a single 8-SOIC surface mount package. This device is designed for applications requiring both high-side and low-side switching, such as DC-DC converters, power management, and motor control circuits. The N-channel MOSFET supports a maximum drain current of 4A, while the P-channel handles 3A, with a common drain-source voltage rating of 30V. The on-resistance is specified at 50mΩ maximum for the N-channel at 2.4A and 10V gate drive. The device features a gate threshold voltage of 1V maximum at 250µA, enabling low-voltage logic level control. Input capacitance is 520pF at 15V, and total gate charge is 25nC at 4.5V, allowing efficient switching. The MOSFETs are housed in an 8-SOIC package with gull wing leads for surface mount assembly. The operating temperature range is -55°C to 150°C, with a maximum power dissipation of 1.4W. The device is RoHS3 compliant and REACH unaffected, with a moisture sensitivity level of 1. This part is suitable for compact designs where board space is limited and complementary switching is required.
