Single Zener Diodes Procurement Notes

Verify the specific suffix CUS/TR against official Microchip documentation to confirm surface-mount MELF configuration and tape-and-reel packaging. Ensure procurement channels are authorized to guarantee compliance with MIL-PRF-19500/406 quality standards. Cross-reference lot traceability requirements with project specifications before ordering.

Single Zener Diodes Selection Notes

Select this component when high-reliability Zener regulation is required in space-constrained surface-mount designs. The ±2% tolerance suits precision applications, while the 1.5 W rating provides adequate power handling. Verify thermal management capabilities align with the -65°C to 175°C operating range for extreme environment deployment.

Single Zener Diodes Part Context

This part belongs to the JAN/JANTXV series of radiation-hardened or high-reliability Zener diodes from Microchip. The JANTXV designation indicates enhanced testing and screening beyond standard JAN levels, targeting defense and aerospace markets. The CUS/TR suffix specifies the surface-mount variant supplied in tape-and-reel format for efficient manufacturing integration.

Single Zener Diodes Replacement Considerations

JAN1N4477CUS/TR offers equivalent parameters in standard military grade. JANTX1N4477CUS/TR provides similar performance with slightly relaxed screening. Verify pinout compatibility and thermal characteristics when substituting.
