Overview

The G5Q-1A4-EL3-HA DC5 is a high-performance power relay designed specifically to handle large inrush currents in compact applications. It features a 5V DC coil and is engineered for motor loads and capacitive switching where initial surge currents can reach up to 30A. This SPST-NO (1 Form A) relay provides a reliable solution for switching power in modern household and industrial electronics.

Why Choose This Part

This relay is specifically optimized for high-inrush durability, capable of surviving 30A surges while maintaining a compact footprint. The sealed construction allows for reliable operation in harsh environments and facilitates easier board cleaning during manufacturing. Its 80mA coil current at 5V makes it compatible with many standard logic-level driver circuits.

Applications

Home Appliance Control
Ideal for controlling compressor motors in refrigerators or heating elements in washing machines that require high inrush handling.
Industrial I/O Modules
Used as an output interface for PLCs to drive external actuators and small motors in factory automation environments.
Smart Lighting Systems
Manages high capacitive inrush currents associated with LED driver circuits and electronic ballasts.
Building Automation
Integrates into HVAC controllers for switching fan motors and circulation pumps.

Getting Started

To integrate this relay, ensure your PCB layout includes adequate trace width for the 30A inrush current and implement a flyback diode (such as a 1N4007) across the coil pins. For prototyping, this component can be used on a perforated board with 2.54mm or compatible power relay pitch, driven by a low-side NPN transistor or MOSFET like the 2N7002.
