AZ943-1CH-5DE
Overview
The AZ943-1CH-5DE is a compact, through-hole general purpose relay from American Zettler featuring a single-pole double-throw (SPDT) configuration. It is designed with a 5VDC non-latching coil and is capable of switching loads up to 15 Amps, making it suitable for power control in restricted spaces. This specific variant is fully sealed to protect contacts from environmental contaminants during soldering and operation.
Why Choose This Part
This relay offers a high switching capacity of 15A in a small footprint, occupying only 19mm by 15.3mm of PCB space. It features a UL Class F insulation system rated for high-temperature environments up to 105 degrees Celsius and provides a fast 10ms operate time for responsive switching.
Applications
Key Specifications
Getting Started
To use this relay, design a PCB with standard 5-pin through-hole footprints and ensure a flyback diode is placed across the 5VDC coil to protect your driving circuitry. Since the coil current is 71.4 mA, use a switching transistor like a 2N2222 or a logic-level MOSFET if driving from an MCU GPIO.
