Back to previous pageProduct introduction：
1. Product Introduction
**IRFZ44S-VB** is a high-performance N-channel MOSFET packaged in TO263. This MOSFET is designed for efficient power switching and current management, with excellent electrical performance and high current handling capability. The maximum drain-source voltage (VDS) of IRFZ44S-VB is 60V, supports a gate-source voltage (VGS) of ±20V, and can handle a drain current of up to 50A. Its turn-on threshold voltage (Vth) is 1.7V, and it uses Trench technology to ensure low on-resistance. At 4.5V gate drive, the on-resistance is 35mΩ, and at 10V gate drive it is 32mΩ. These features make the IRFZ44S-VB particularly suitable for circuit designs that require high power and high efficiency, such as power conversion and motor drive applications.
