AZ977-1C-24DSE

Relay Automotive Overview

The AZ977-1C-24DSE is a 20 AMP miniature power relay designed for automotive applications. It features a SPDT (1 Form C) contact arrangement with resistive load ratings up to 280 W, 20 A, and 150 VDC. The coil operates at 24 VDC nominal voltage. Dielectric strength is 1000 VDC between coil and contacts, and 500 VDC between open contacts. Mechanical life expectancy is 1 x 10^6 operations, while electrical life is 1 x 10^5 operations at 20 A. Operate time is max 10 ms and release time is max 7 ms at nominal coil voltage. Insulation resistance is min 100 megohms at 20°C.

Relay Automotive Procurement Notes

Verify the specific suffix 'SE' against the manufacturer's official documentation to confirm compliance with RoHS standards and lead-free requirements. Ensure the ordering part number matches the exact contact form and coil voltage specifications required for the target application circuit.

Relay Automotive Selection Notes

Select this component when a 20 Amp switching capacity is required within a small physical envelope. The 24 VDC coil voltage must align with the system supply. Consider the 150 VDC maximum switching limit and ensure that operating voltages above 30 VDC trigger the necessary special precautions outlined in the technical data.

Relay Automotive Part Context

This relay belongs to the AZ977 series, which is categorized as a miniature power relay intended for automotive use. The series offers both 1 Form A and 1 Form C contact configurations. The AZ977-1C-24DSE represents the SPDT variant with a 24 VDC coil, providing robust performance for demanding power switching tasks.

Relay Automotive Replacement Considerations

Direct substitutes include other variants within the AZ977 series such as the AZ977-1C-12D or AZ977-1C-6D, provided the coil voltage matches the application requirements. Verify mechanical dimensions and pinout compatibility before substitution.
