1N5276B

Single Zener Diodes Overview

The Microchip Technology 1N5276B is a 0.5 W glass axial-lead Zener diode in the DO-35 package. It provides a nominal Zener voltage of 150 V with a ±5% tolerance. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 100 µA at 108 V. Electrical characteristics include a test current of 0.85 mA, a maximum Zener impedance of 1500 Ω, and a positive voltage temperature coefficient of +0.110 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance for high-frequency applications
• Inherently radiation hard per MicroNote 050
• Non-sensitive to electrostatic discharge (ESD)

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Power supply regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' confirms the required ±5% voltage tolerance. Confirm the manufacturer origin, as the datasheet identifies Microsemi while distributors may list Microchip Technology. Ensure the package type matches the required DO-35 axial lead configuration for your assembly process.

Single Zener Diodes Selection Notes

Select this component when a precise 150 V regulation point is needed with tight tolerance. Consider the positive temperature coefficient for thermal stability requirements. Verify that the 0.5 W power dissipation rating meets the circuit's thermal load under all operating conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 V to 200 V. The 'B' suffix specifically denotes a standard 5% voltage tolerance, distinguishing it from A (10%), C (2%), or D (1%) variants.
