1N5276A

Single Zener Diodes Overview

The Microchip Technology 1N5276A is a single Zener diode housed in a DO-35 (DO-204AH) glass axial-lead package. It provides a nominal Zener voltage of 150 V with a tolerance of ±10%. The device supports a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse current of 100 nA at 114 V, a maximum Zener impedance of 1500 Ohms, and a forward voltage of 1.5 V at 200 mA.

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
• Constructed with a hermetically sealed glass body for durability
• Inherently radiation hard per MicroNote 050

Single Zener Diodes Applications

• Voltage regulation circuits requiring high-voltage stability
• Reference voltage sources in electronic systems
• Overvoltage protection applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' to confirm the 10% tolerance specification, as other suffixes indicate different tolerances or packaging. Confirm RoHS compliance status by checking for the 'e3' suffix if required, as standard versions may not be compliant. Ensure the manufacturer source is identified correctly, as historical data links this part to Microsemi Scottsdale Division, now part of Microchip Technology.

Single Zener Diodes Selection Notes

Select the 1N5276A when a 150 V breakdown voltage with ±10% tolerance is required. Consider the DO-35 package for through-hole designs. Evaluate the thermal resistance of 250 °C/W junction-to-lead for heat dissipation planning. Verify that the maximum reverse current and impedance values meet the circuit's leakage and stability requirements.

Single Zener Diodes Part Context

This component 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 'A' suffix specifically denotes a standard 10% voltage tolerance, distinguishing it from tighter tolerance options like 'B' (5%) or military screening prefixes.
