1N5276B/TR

Single Zener Diodes Overview

The Microchip Technology 1N5276B/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 150 V with ±5% tolerance. It operates within a temperature range of -65°C to +175°C and includes a tape-and-reel option for automated assembly.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Offers minimal capacitance characteristics suitable for high-frequency applications

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference levels
• Overvoltage protection systems
• Clamping applications in electronic signal paths

Single Zener Diodes Procurement Notes

Verify that the suffix 'TR' confirms the tape-and-reel packaging format required for automated surface mount or through-hole placement equipment. Ensure the B suffix indicates the specific 5% voltage tolerance needed for the design. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Single Zener Diodes Selection Notes

Select this component when a 150 V breakdown voltage with tight 5% tolerance is required. The DO-35 glass package supports high-temperature operation up to 175°C. Verify that the 0.5 W power dissipation rating meets the thermal requirements of the target circuit environment.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series provides a wide selection of voltages from 2.4 V to 200 V in standard JEDEC registered formats. The B suffix specifically denotes a tighter 5% voltage tolerance compared to the standard A suffix.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5276B and 1N5276B-1. Verify pinout compatibility and ensure the replacement maintains the same DO-35 axial lead configuration and 500 mW power rating.
