## Overview

The JZK 4Pcs LR7843 MOSFET Module is a high-current, 30V-rated field-effect transistor module featuring optocoupler isolation to eliminate interference. Compatible with 3V and 5V microcontroller signals, it supports PWM speed regulation and is ideal for controlling motors, solenoid valves, and other equipment. This quad pack offers a reliable, cooler-running alternative to common IRF520 modules, perfect for professional-grade electronics projects.

## Description

Package included: 4 pcs LR7843 MOSFET module Voltage:30V, 161A. With optocoupler isolation, the control signal is isolated from the power supply of the controlled device, which greatly improves the interference. Compatible with single chip microcomputer light control board, 3V or 5V signal. v High level start, low level stop, PWM speed regulation. Widely used to control the start and stop of motors, solenoid valves and other tributary equipment.

Review: Much better than the commonplace IRF520 versions. The LR7843 triggers fine from 3.3V/5V sources, and the optocoupler is a bonus. Much lower voltage drop across the MOSFET in use, which means it stays cooler and delivers more power to the circuit. Turfing all of those cheap IRF520 ones now, in favour of these beasts!

*by C***S on 23 November 2023*

Prodotto viene venduto come capace di sostenere tensioni fino a 30V e correnti fino a 161A, indovinate cosa è successo dopo 4 secondi a 14.5v e 9.5A? esatto, ha letteralmente preso fuoco. Assolutamente sconsigliato
