1N5276

Single Zener Diodes Overview

The Microchip Technology 1N5276 is a single Zener diode housed in a DO-35 glass axial-lead package. It provides a nominal Zener voltage of 150 V with a maximum power dissipation of 500 mW. The device features a reverse leakage current of 100 nA at 114 V and a maximum Zener impedance of 1500 Ohms. It operates within a temperature range of -65°C to 175°C junction temperature.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a silicon Zener junction
• Constructed with a hermetically sealed glass axial-lead package for environmental protection
• Designed for through-hole mounting on printed circuit boards

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications for signal lines

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix (e.g., A, B, C) required for your design, as the base part number denotes the voltage class but not the precision grade. Confirm RoHS compliance status, as standard versions may differ from lead-free variants. Ensure the selected variant matches the required thermal management capabilities for the intended operating environment.

Single Zener Diodes Selection Notes

Select this component when a 150 V regulation point is needed in a low-power application. Evaluate the 500 mW power rating against expected surge currents to ensure safe operation. Compare the 1500 Ohm impedance value against load requirements to determine if tighter regulation is necessary, potentially requiring a different series or tolerance grade.

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 in standard packages. These devices are widely used in general-purpose electronics for basic voltage stabilization tasks.
