AZ979-1A-12DRE

Relay Automotive Overview

The AZ979-1A-12DRE is an 80 Amp automotive relay manufactured by American Zettler. It features a 12VDC coil and SPST N.O. (1 Form A) contact arrangement. The device supports high momentary carry current and operates at temperatures up to 85°C. Key electrical ratings include a maximum switched power of 840 W, maximum switched current of 60 A, and maximum switched voltage of 30 VDC for resistive loads. Mechanical life expectancy is 1 x 10^7 operations, while electrical life is 1 x 10^5 operations at 80 A. Dielectric strength is 500 Vrms between coil and contacts.

Relay Automotive Procurement Notes

Verify the specific suffix 'RE' against the manufacturer's official documentation to confirm compliance with RoHS directives and lead-free requirements. Ensure the ordering part number matches the exact coil voltage and contact form required for the target application. Cross-reference the datasheet revision date to confirm the validity of the dielectric strength and life expectancy specifications provided in the component data.

Relay Automotive Selection Notes

Select this component when an 80 Amp switching capacity is required within a Mini-ISO automotive relay footprint. The 12VDC coil specification suits standard vehicle electrical systems. Consider the epoxy sealed version if the installation environment requires protection against moisture or contaminants. Verify that the 30 VDC maximum switched voltage aligns with the load circuit requirements.

Relay Automotive Part Context

This model belongs to the AZ979 series of 80 Amp automotive relays produced by ZETTLER Electronics. The series offers multiple contact arrangements including SPST N.O., SPDT, and SPST N.C. variants. The AZ979-1A-12DRE specifically denotes the Single Pole Single Throw Normally Open configuration with a 12VDC coil, designed for high-current automotive applications requiring reliable switching performance.

Relay Automotive Replacement Considerations

The AZ979-1A-12DRE serves as a direct replacement for other Mini-ISO style 80 Amp automotive relays with identical 12VDC coils and SPST N.O. contacts. Verify physical dimensions and terminal orientation compatibility before substitution. Consult the manufacturer's cross-reference list for approved equivalent part numbers.
