Overview

The ALZ11F12 is a compact 16A power relay from Panasonic's ALZ (LZ) series, featuring an SPDT (1 Form C) contact arrangement. It is designed for high-capacity switching in a small footprint, capable of handling AC voltages up to 440V and temperatures up to 105 degrees Celsius. This flux-resistant through-hole relay is optimized for applications requiring reliable power switching with a 12VDC coil.

Why Choose This Part

This relay offers a high switching capacity of 16A in a low-profile package with a length of 28.8mm and height of 15.7mm. It features a wide operating temperature range from -40 to +105 degrees Celsius, making it suitable for harsh thermal environments. Additionally, its low coil current of 33.3 mA facilitates energy-efficient operation in multi-relay control boards.

Applications

Home Appliances
Ideal for switching heating elements, motors, and compressors in refrigerators, washing machines, and air conditioners.
HVAC Controls
Used in thermostats and furnace controllers to manage high-voltage blower fans and valve actuators.
Industrial PLC Output Modules
Provides a robust interface for programmable logic controllers to drive external heavy loads up to 16A.
Lighting Control Systems
Suitable for automated building lighting where high inrush currents from LED drivers or ballast loads are present.

Getting Started

When integrating the ALZ11F12, ensure a flyback diode is placed across the 12VDC coil to protect driving circuitry from inductive spikes. Verify that the PCB traces for the 16A load are sized with sufficient copper weight and width to manage heat dissipation. Refer to the footprint dimensions of 28.8mm by 12.5mm for layout, ensuring adequate creepage and clearance for high-voltage AC paths.
