Single Diodes Procurement Notes

Verify the specific datasheet revision and electrical tolerances directly with Microchip Technology before integration. Confirm that the DO-7-2 through-hole package aligns with your PCB layout requirements. Ensure the operating environment stays within the specified -55 C to +175 C range to maintain regulatory accuracy. Cross-reference the 242 uA nominal current value with your design constraints to prevent under-performance.

Single Diodes Selection Notes

Select this component when a stable, low-current reference is required without active feedback loops. The high temperature rating makes it suitable for industrial or automotive environments where thermal stability is critical. Compare the 500 mW power dissipation capability against expected load variations to ensure adequate thermal headroom. Verify compatibility with the 100 V peak voltage limit for your specific supply rails.
