1N5272B

Single Zener Diodes Overview

The Microchip Technology 1N5272B is a 0.5 W glass axial-lead Zener diode housed in a DO-35 package. It provides a nominal Zener voltage of 110 V with a ±5% 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 84 V. Its Zener impedance is specified at 750 Ohms, with a positive voltage temperature coefficient of +0.11 %/°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
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the datasheet originates from Microsemi while other records list Microchip Technology. Confirm RoHS compliance status by checking for the 'e3' suffix if required. Ensure the ordering part number matches the desired tolerance and packaging format before procurement.

Single Zener Diodes Selection Notes

Select this component when a 110 V Zener voltage with tight 5% tolerance is required. The DO-35 through-hole package suits standard PCB layouts. Consider the positive temperature coefficient for thermal stability requirements in the design phase.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener diodes. The series offers voltages from 2.4 V to 200 V. The 'B' suffix specifically denotes a ±5% voltage tolerance, distinguishing it from 'A' (10%) or tighter tolerance variants.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package. Verify pinout compatibility and power derating curves when transitioning between axial-lead and surface-mount formats.
