Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application. The 'TR' suffix indicates tape and reel packaging per EIA-481-1-A standards. Confirm that the standard ±5% tolerance meets your circuit design specifications before procurement. Ensure compatibility with the DO-213AA footprint on your PCB layout.

Single Zener Diodes Selection Notes

Select this component when a surface mount equivalent to the axial-leaded 1N4134 is required. Consider the 0.5-watt power dissipation limit and the thermal resistance values for your mounting conditions. Verify that the 91 V Zener voltage aligns with your reference needs. Check if tighter tolerances or military qualifications are necessary for your specific environment.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass surface mount Zener diodes. These devices serve as surface mount equivalents to JEDEC registered axial-leaded parts. The series offers voltages from 1.8 to 100 V in standard 5% tolerances, with options for tighter tolerances and military qualifications available via different suffixes.
