ALZ51F05W
Overview
The ALZ51F05W is a 16A power relay from Panasonic designed for high-capacity switching in a compact through-hole form factor. It features a 5V DC coil and a single-pole single-throw normally open (SPST-NO) contact arrangement, specifically engineered to handle 250V AC loads. With its Class F insulation rating, this relay is capable of operating in ambient temperatures up to 105 degrees Celsius.
Why Choose This Part
This relay offers a slim 12.5mm profile, saving significant PCB real estate in dense power electronics designs. Its EN60335-1 GWT compliance and high heat resistance make it an ideal choice for consumer safety-critical applications. The Class F insulation system provides superior reliability in harsh thermal environments compared to standard Class B components.
Applications
Key Specifications
Getting Started
When integrating this relay, ensure the PCB traces are sized appropriately for the 16A maximum current and include a flyback diode across the coil to protect the 5V driving circuit from inductive spikes. For high-temperature designs, verify that the 80mA coil current will not exceed the thermal budget of your power supply or driver IC at 105 degrees Celsius.
