Single Zener Diodes Procurement Notes

Verify that the specific part number includes the CUR-1 suffix to confirm the surface-mount variant and manufacturing lot traceability. Ensure compliance with MIL-PRF-19500/117 standards is documented for procurement acceptance. Confirm RoHS status as non-compliant due to military specifications. Validate packaging details against official Microchip documentation prior to order placement.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, low-noise Zener diode is required for high-reliability applications. The 47 V rating and 500 mW power handling define its operational limits. Consider the DO-213AA footprint for PCB layout compatibility. Verify thermal management requirements align with the specified operating temperature range.

Single Zener Diodes Part Context

This component belongs to the JAN series of Zener diodes produced by Microchip Technology, formerly Microsemi. The JAN prefix indicates adherence to Joint Army-Navy specifications for military-grade semiconductors. These devices are engineered for durability and consistent electrical performance in demanding environments where standard commercial parts may fail.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JAN-series Zener diodes with identical voltage and power ratings from Microchip. Cross-reference with MIL-PRF-19500/117 qualified parts from authorized manufacturers. Verify pinout and package dimensions match before substitution.
