1N5271B-1

Single Zener Diodes Overview

The Microchip Technology 1N5271B-1 is a single silicon Zener diode housed in a DO-204AH (DO-35) axial through-hole package. It provides a nominal Zener voltage of 100 V with a tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range of -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA at 76 V, a Zener impedance of 500 Ohms, and a test current of 1.3 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Utilizes a hermetically sealed glass axial leaded package for environmental protection
• Features low reverse leakage current for high-impedance circuit applications

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' against official Microchip documentation to confirm it denotes a military or space-grade variant distinct from the commercial 1N5271B. Confirm RoHS compliance status as commercial grades may differ from hermetic variants. Validate that the DO-204AH package dimensions match your PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 100 V reference is needed in a standard through-hole form factor. The ±5% tolerance suits general regulation tasks where tight precision is not critical. Ensure the 500 mW power rating accommodates the expected thermal load in the target enclosure environment.

Single Zener Diodes Part Context

This part belongs to the 1N5271 series of Zener diodes manufactured by Microchip Technology. The series offers an extensive selection of voltage values ranging from 2.4 V upwards. The 1N5271B-1 specifically represents a variant within this lineup, maintaining the standard 100 V specification while potentially adhering to stricter manufacturing or reliability standards associated with the suffix.
