Additional Details:

The SIR172ADP is offered in a PowerPAK SO-8 package. Typical specifications include a drain-source voltage (VDS) of 30V, continuous drain current (ID) rating of 13A, and a maximum RDS(on) of 5.5 mΩ at VGS = 10V. The gate threshold voltage is typically between 1V and 2.5V. This MOSFET is designed for surface mount technology (SMT) assembly. It complies with RoHS standards. The device's pulsed drain current rating is notably higher than its continuous rating, allowing it to handle transient peak currents.
