1N5271A

Single Zener Diodes Overview

The Microchip Technology 1N5271A is a 0.5-watt glass axial-lead Zener diode housed in a DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 100 V with a ±10% tolerance. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse leakage current of 100 nA at 76 V. Its maximum Zener impedance is 2600 Ohms, and the forward voltage is 1.5 V at 200 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for environmental stability
• JEDEC registered part number ensuring standardized electrical characteristics
• Capable of regulating voltage across a broad operating current and temperature range

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the component matches the specific JEDEC registration requirements for your design. Confirm the suffix 'A' corresponds to the required 10% tolerance level. Ensure the DO-35 package dimensions align with your PCB footprint constraints before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a standard 100 V Zener reference is needed in an axial-lead form factor. Consider the 500 mW power dissipation limit and derating curves for thermal management. Evaluate the high impedance value against circuit loading requirements compared to lower-voltage alternatives.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5-watt Zener voltage regulators. The series offers a wide selection of voltages from 2.4 V to 200 V. The 1N5271A specifically addresses the 100 V segment of this extensive lineup.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5271 without suffix or other manufacturers' 1N5271 variants. Verify that replacement units maintain the same DO-35 package and 10% tolerance specifications.
