1N4615UR-1/TR

Single Zener Diodes Overview

The 1N4615UR-1/TR is a surface mount Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 2 V with a tolerance of ±5%. The device has a power dissipation rating of 500 mW and operates in the DO-213AA (SMB) package. Key electrical parameters include a maximum reverse leakage current of 2.5 uA, a Zener impedance of 1250 Ohms, and a test current of 250 uA. It supports a forward current of 200 mA and functions within a temperature range of -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation for low-voltage circuits
• Utilizes metallurgically bonded glass construction for reliability
• Designed for surface mount assembly processes

Single Zener Diodes Applications

• Voltage reference applications
• Overvoltage protection circuits
• Clamping and switching applications

Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 indicates the round-end variant when sourcing replacements. Confirm the DO-213AA package footprint matches the design requirements. Check for RoHS compliance status if environmental regulations apply to the target assembly. Ensure the reel packaging format aligns with automated placement equipment capabilities.

Single Zener Diodes Selection Notes

Select this component for designs requiring a stable 2 V reference in a compact surface mount form factor. The high operating temperature range suits demanding environments. Consider the 1250 Ohm impedance for noise-sensitive applications where lower dynamic resistance might be required.

Single Zener Diodes Part Context

This part belongs to Microchip's line of single Zener diodes. It is part of the 1N4615 series, which includes various package options such as axial leaded and other surface mount variants. The UR-1 designation specifically denotes the surface mount version with round ends, distinguishing it from standard axial or square-end packages.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N4615UR-1 without the /TR suffix for bulk packaging. Other manufacturers offering equivalent 2V Zener diodes in DO-213AA packages may serve as alternatives if pin compatibility and electrical specifications are verified.
