Single Zener Diodes Procurement Notes

Verify component authenticity against official Microchip Technology documentation before integration. Confirm that the DO-204AH-2 package dimensions align with the target PCB layout. Ensure operational parameters remain within the specified thermal limits during system design. Cross-reference datasheet values for leakage current and impedance to validate performance requirements.

Single Zener Diodes Selection Notes

Select this component when a high-voltage Zener reference is required in a through-hole configuration. The 200 V rating distinguishes it from lower-voltage variants in the series. Consider the 500 mW power dissipation limit when designing heat management strategies. The axial package style dictates specific board spacing and mounting constraints compared to surface-mount alternatives.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family produced by Microchip Technology. It shares common electrical characteristics with other devices in the series but is distinguished by its specific 200 V breakdown voltage. The product line supports various voltage ratings and package styles to accommodate diverse electronic design needs across multiple industries.

Single Zener Diodes Replacement Considerations

The 1N992A/TR serves as a parameter-equivalent alternative within the same manufacturer lineup. Both devices share identical voltage and power specifications but differ in packaging style and leakage current ratings.
