The driver of the stepper motor usually adopts the PWM (Pulse Width Modulation) technology to control the current and torque. The switching speed of the MOS tube will directly affect the quality of the PWM signal and the driving frequency. Therefore, a fast-switching MOS tube helps improve driving accuracy and response speed.

In the era of localization, it is very important to select a good MOS tube for use in the circuit. Today, we introduce a domestic MOS tube that can replace several models of MOS tubes including 11N40, 10N40, and IRF740 for application in stepper motor drivers!

As an N-channel enhancement-mode field-effect transistor with characteristics of 10A and 400V, electronic engineers can not only apply it in stepper motor drivers but also in full-bridge circuits of inverters with 500W/AC220V square wave output, switch power supplies, and other application scenarios.

When selecting, the on-resistance, voltage endurance, rated current, switching speed, thermal characteristics, switching losses, etc., are all core issues we need to pay attention to.

Currently, the main package form of FHP740W is TO-220, with the pin arrangement being GDS.

Specific parameters of this 740 FET product: Vgs (±V): 30; VTH (V): 2-4; ID (A): 10; BVdss (V): 400. RDS(on) = 0.55mΩ(typ)@VGS=10V.

This product has excellent consistency, high reliability, high avalanche tolerance, and low on-resistance, which are the product parameter features that can replace 11N40, 10N40, and IRF740.

If you want to introduce a 10A low current, 400V high voltage, 0.55 ohm on-resistance MOSFET, the pure domestic FHP740W model is highly recommended for use in stepper motor drivers.

For the replacement of 10A and 400V MOSFETs, selecting the right model is very important for energy storage inverters. The MOSFETs from Feihong Semiconductor are widely used in stepper motor drivers as well as in outdoor energy storage power supplies, frequency converters, photovoltaic inverters, welding machines, industrial sewing machines, and other end applications.
