Overview

The ALZ11F05W is a 5VDC coil power relay from Panasonic's LZ series, designed for high-capacity switching up to 16A. This SPDT (1 Form C) relay features a low-profile 15.7 mm height and is GWT compliant, making it suitable for modern appliance and building automation designs.

Why Choose This Part

The relay offers superior heat and tracking resistance with a Class F insulation rating. Its compact footprint (28.8mm x 12.5mm) allows for high-density PCB layouts while maintaining a 16A switching capacity and flux-resistant sealing.

Applications

Smart Home Appliances
Switching heating elements or motors in washers, dryers, and dishwashers due to EN60335-1 GWT compliance.
Industrial PLC Output Modules
Providing isolated high-current switching for industrial controllers in a compact form factor.
HVAC Controls
Driving fans, pumps, and compressors in thermostats and air conditioning control boards.
Power Strips and Smart Plugs
Managing mains power switching in consumer smart home energy management devices.

Getting Started

To drive the 80mA coil from a microcontroller, use a logic-level N-channel MOSFET and a flyback diode (e.g. 1N4148) to protect against inductive spikes. Ensure PCB traces for the 16A load are sufficiently wide and use heavy copper weights to manage thermal rise.

Also Consider

G5Q-14 DC5 Omron Electronics - A widely used alternative with a similar SPDT footprint but typically rated for 10A applications.
RT314005 TE Connectivity - Offers 16A switching in a standard 12.7mm width package with 5kV isolation between coil and contacts.
