Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required military or commercial qualifications. Confirm that the DO-213AA footprint matches the target PCB layout. Request updated compliance documentation to verify RoHS status and material declarations prior to final procurement authorization.

Single Zener Diodes Selection Notes

Select this component when a low-noise, high-reliability Zener regulator is required in a compact surface-mount form factor. The ±2% tolerance makes it suitable for precision applications where standard 5% parts are insufficient. Ensure the circuit design accommodates the 500 mW power rating and the specific thermal characteristics of the glass-bonded construction.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR-1 through 1N4135UR-1 series of metallurgically bonded glass surface mount Zener diodes. These devices serve as surface-mount equivalents to traditional axial-leaded JEDEC registered parts, offering improved mechanical stability and suitability for harsh environments due to their internal bonding technology.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' DO-213AA packaged Zener diodes with identical 15V ratings and ±2% tolerance. Verify that any replacement also features internal metallurgical bonding if environmental ruggedness is a critical requirement.
