Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application. The 'TR' suffix indicates tape and reel packaging, while the base part number defines the electrical parameters. Confirm that the manufacturer documentation supports the exact ordering code before finalizing procurement to ensure compliance with project specifications.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required. The 1N4115UR provides a 22 V reference with standard tolerance. Consider the thermal resistance and power derating curves if operating near maximum ratings. Ensure the DO-213AA footprint matches the PCB layout constraints.

Single Zener Diodes Part Context

This device belongs to the 1N4099UR through 1N4135UR series of 0.5 watt glass surface mount Zeners. These regulators are designed as surface mount equivalents to JEDEC registered axial-leaded parts. The series offers voltages from 1.8 to 100 V with standard 5% tolerances.
