Single Zener Diodes Procurement Notes

Verify that the specific order includes the CUR-1 suffix, which denotes the surface-mount DO-213AA-2 package variant, distinct from through-hole versions. Confirm compliance requirements as the device is not RoHS compliant. Ensure procurement channels are authorized for military-grade components subject to export controls. Request full datasheet and certification documents upon order confirmation to validate lot traceability and manufacturing origin.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, surface-mount Zener diode with military qualification is required. The DO-213AA-2 package offers space efficiency compared to axial leads while maintaining ruggedness. Consider the 24V nominal voltage and 500mW power rating against circuit load requirements. Verify thermal management capabilities given the extended temperature range and potential self-heating effects in dense PCB layouts.

Single Zener Diodes Part Context

This part belongs to the 1N5542 series of Zener diodes produced by Microchip Technology (formerly Microsemi). The JANTX designation indicates a specific quality level within the military product line. The CUR-1 suffix specifies the tape-and-reel or bulk surface-mount configuration. This series is engineered for high-reliability applications where standard commercial components would fail due to environmental stress or longevity demands.

Single Zener Diodes Replacement Considerations

Direct functional equivalents may include JAN1N5542CUR-1 for standard military grade. Verify pinout compatibility and package dimensions when substituting with other manufacturers' DO-213AA devices. Ensure replacement parts meet the same MIL-PRF-19500/437 specification if military certification is mandatory.
