Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure compatibility with required packaging and handling standards. Confirm RoHS compliance status as indicated in the datasheet, noting that certain variants may not meet standard environmental directives. Cross-reference the exact part number with authorized distributors to validate authenticity and traceability before procurement.

Single Zener Diodes Selection Notes

Select this component when high stability over temperature is critical. The ±1% tolerance offers superior accuracy compared to standard Zener diodes. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specific test current requirements for optimal performance.

Single Zener Diodes Part Context

This part belongs to the 1N4565 series of temperature-compensated Zener diodes manufactured by Microchip Technology. It is functionally equivalent to the through-hole 1N4565 variant but packaged for surface-mount technology. The series is characterized by its low temperature coefficient, making it distinct from general-purpose Zener diodes.

Single Zener Diodes Replacement Considerations

The 1N4565 is the direct through-hole equivalent. Verify pinout and thermal characteristics when substituting between package types.
