Panasonic Electric Works
General Purpose Relay SPDT (1 Form C) 5VDC Coil Through Hole
Active

Overview

The ALZ12B05W is a compact SPDT (1 Form C) power relay from Panasonic's ALZ series designed for high-current switching in a small footprint. It features a 5VDC coil with 80mA current consumption and is rated to switch loads up to 16A at 440VAC.

Why Choose This Part

This relay offers a low-profile height of 15.7mm and Class B insulation for operation in ambient temperatures up to 85C. Its fully sealed construction and high tracking resistance make it reliable in harsh environments and compliant with global safety standards for domestic appliances.

Applications

Household Appliances
Ideal for switching heating elements or motors in washing machines, refrigerators, and dishwashers due to its EN60335-1 GWT compliance.
HVAC Controls
Used in thermostats and boiler controllers to manage high-voltage fans and pumps.
Industrial Automation
Suitable for PLC output modules requiring high switching capacity in a low-profile through-hole package.
Smart Lighting
Effective for controlling high-power LED driver circuits or incandescent lighting banks.

Getting Started

When designing with the ALZ12B05W, ensure the PCB trace widths can handle the 16A maximum load and include a flyback diode across the 5VDC coil to protect driving circuitry from inductive spikes. Refer to the footprint layout for correct SPDT pin orientation to maintain creepage and clearance distances.
