Single Zener Diodes Procurement Notes

Verify that the specific suffix UR-1/TR corresponds to the required surface-mount DO-213AA configuration and reel packaging. Confirm military grade compliance requirements against MIL-PRF-19500/435 specifications before procurement. Ensure compatibility with automated assembly processes due to the small outline package format.

Single Zener Diodes Selection Notes

Select this component when high precision voltage referencing is required in space-constrained military designs. The ±1% tolerance offers superior accuracy compared to standard commercial variants. Consider the DO-213AA footprint constraints during PCB layout to ensure adequate thermal dissipation for the 500 mW rating.

Single Zener Diodes Part Context
