1N4615UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4615UR/TR is a glass surface mount Zener voltage regulator in the DO-213AA package. It provides a nominal Zener voltage of 2.0 V with a standard tolerance of ±5%. The device operates at a test current of 250 µA and features a maximum Zener impedance of 1250 Ω. It supports a steady-state power dissipation of 0.5 W and functions within an operating temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF-style surface mount package
• Internal metallurgical bond option available for enhanced reliability
• Inherently radiation hard construction
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation in surface mount circuits
• Reference voltage generation
• Protection against overvoltage transients

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application, as the TR suffix indicates tape and reel packaging. Confirm that the standard 5% tolerance meets your circuit design specifications. Ensure compatibility with the DO-213AA footprint during PCB layout. Check for RoHS compliance if required by your manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference near 2V is needed in a compact surface mount form factor. Consider the internal metallurgical bond option if higher reliability is required. Evaluate the thermal resistance and derating curves to ensure adequate heat dissipation under maximum load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4614UR through 1N4627UR 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 a wide selection of voltages from 1.8 to 100 volts with various tolerance options.

Single Zener Diodes Replacement Considerations

Equivalent axial-leaded parts include the 1N4615. Surface mount alternatives within the same series are MLL4615. Parts with tighter tolerances may require C or D suffixes.
