Additional Details:

The IRF7103 has a drain-source voltage (Vds) rating of -30V and a continuous drain current (Id) rating of -5.8A. The typical RDS(on) value at Vgs = -4.5V is 0.045 Ohms. The gate threshold voltage is typically between 1V and 2.5V. It is available in a SO-8 package.

This MOSFET is particularly well-suited for applications where space is limited and high efficiency is required. Its logic-level gate drive makes it easy to integrate into microcontroller-based systems, and its low RDS(on) ensures minimal power loss. The avalanche rating provides an extra margin of safety and reliability.
