AZ977-1A-24DSE

Relay Automotive Overview

The AZ977-1A-24DSE is a 20 AMP miniature power relay designed for automotive applications. It features a SPST (1 Form A) contact arrangement with a nominal coil voltage of 24 VDC. The device supports resistive loads up to 280 W and a maximum switched current of 20 A at voltages up to 150 VDC. Mechanical life expectancy is rated at 1 x 10^6 operations, while electrical life is 1 x 10^5 operations at 20 A and 14 VDC resistive load. Typical operate time is 10 ms max, and release time is 7 ms max.

Relay Automotive Feature Summary

• Designed for high in-rush applications with vibration and shock resistance
• Compact footprint suitable for space-constrained automotive environments
• Socketable construction for simplified installation and replacement

Relay Automotive Applications

• Automotive electrical systems
• High in-rush load switching
• Vehicle accessory control circuits

Relay Automotive Procurement Notes

Verify the specific suffix 'SE' against the manufacturer's official datasheet to confirm socketability and sealing specifications. Ensure the application environment remains within the specified temperature range and that switching voltages do not exceed 150 VDC without factory consultation. Confirm coil voltage tolerance matches the 24 VDC nominal requirement for reliable operation.

Relay Automotive Selection Notes

Select this component when a robust, compact relay capable of handling 20 A resistive loads is required. The SPST configuration provides simple on/off control. Consider the mechanical and electrical life ratings against the expected duty cycle. Verify that the small footprint fits the available board space and that the socketable design aligns with maintenance requirements.

Relay Automotive Part Context

This part belongs to the AZ977 series of miniature power relays manufactured by American Zettler. The series is characterized by its ability to switch up to 20 Amps in a compact size, making it distinct from higher-current or lower-current alternatives within the broader product portfolio.

Relay Automotive Replacement Considerations

Compatible substitutes include other AZ977 variants with matching coil voltages and contact forms, such as AZ977-1A-12D for 12VDC applications. Cross-reference pinouts and dimensions to ensure physical compatibility.
