Single Zener Diodes Procurement Notes

Verify the specific revision level and lot traceability requirements before procurement. Confirm that the TO-204AD package dimensions match the target PCB or chassis layout. Ensure compliance with project-specific material restrictions and quality standards required for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 25 V Zener voltage with 5 W power handling is required in a TO-204AD package. Consider the ±5% tolerance for precision requirements. Evaluate thermal management needs to ensure the junction temperature remains within safe operating limits during continuous operation.

Single Zener Diodes Part Context

This part belongs to the JAN series of discrete semiconductors produced by Microsemi. The JAN series typically denotes military-grade or high-reliability variants. The TO-204AD package is a standard metal can style often used in aerospace and defense electronics for its durability and thermal performance.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 25 V Zener voltage, 5 W power rating, and TO-204AD package. Verify pinout compatibility and electrical characteristics such as impedance and temperature coefficient. Cross-reference with other manufacturers offering equivalent military-grade Zener diodes in the same form factor.
