Procurement Notes

Verify the specific suffix 'UB2R' against the manufacturer's official datasheet to confirm the reel packaging format and exact electrical tolerances. Ensure the procurement channel provides valid traceability documentation required for aerospace or military grade components. Cross-reference the manufacturing date code to ensure compliance with any active product change notifications issued by Microchip Technology.

Selection Notes

Select this component when a hermetically sealed surface mount diode is required for high-frequency signal processing. The 75 V rating suits low-voltage logic interfaces. Consider the 300 mA current limit for driving small loads. The wide temperature range makes it suitable for industrial or defense applications where standard plastic packages may fail under thermal stress.
