Product introduction：
1. Product Introduction
**IRFZ45-VB** is a high-performance N-channel MOSFET in TO220 package with strong current handling capability and efficient switching characteristics. The device has a maximum drain-source voltage (VDS) of 60V, supports a gate-source voltage (VGS) of ±20V, and its threshold voltage (Vth) is 1.7V. IRFZ45-VB uses advanced Trench technology to give it low on-resistance. At a gate drive of 4.5V, the on-resistance is 28mΩ, while it drops to 24mΩ at a gate drive of 10V, and can withstand a drain current of up to 50A. This MOSFET is ideal for use in applications such as efficient power switches, DC-DC converters, and switching power supplies.
