Single Zener Diodes Procurement Notes

Verify authenticity by purchasing only from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm the 'A' suffix indicates 5% voltage tolerance and the 'TP' suffix denotes RoHS compliance. Ensure the application does not involve life support devices without explicit written approval from the manufacturer.

Single Zener Diodes Selection Notes

Select this component for applications demanding high operating temperatures up to 175°C and robust transient protection. The DO-213AB package offers compact surface-mount integration. Consider the 175Ω dynamic impedance and 5µA reverse current when designing low-power reference circuits.

Single Zener Diodes Part Context

This part belongs to the DL4728 through DL4761 series of 1W Zener diodes manufactured by MCC. The series covers a voltage range from 3.3V to 75V. The DL4761 represents the highest voltage option in this specific glass MELF lineup, providing a stable 75V breakdown point for circuit design.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as SMAJ4761A and MLL4761A. Axial lead versions such as MQ1N4761P may serve as functional substitutes if package constraints allow.
