1N5272A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5272A/TR is a 0.5 W glass axial-lead Zener diode with a nominal voltage of 110 V and ±10% tolerance. It operates within a temperature range of -65°C to +175°C, featuring a maximum reverse current of 80 μA at 94 V and a Zener impedance of 750 Ω at 0.25 mA. The device utilizes a DO-35 package and includes a tape-and-reel suffix for automated surface mounting.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance characteristics suitable for high-frequency applications
• Offers flexible axial-lead mounting terminals for through-hole integration

Single Zener Diodes Applications

• Voltage reference circuits requiring stable breakdown voltage
• Overvoltage protection in electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct tolerance and packaging specifications. Confirm RoHS compliance status if required by project standards. Cross-reference JEDEC registration numbers for compatibility with existing design libraries. Validate thermal derating requirements based on final PCB copper pad dimensions and ambient conditions.

Single Zener Diodes Selection Notes

Select this component when a 110 V breakdown voltage with standard tolerance is required. Ensure the application environment stays within the specified -65°C to +175°C operational limits. Consider the 0.5 W power dissipation rating and verify adequate heat sinking or board layout for thermal management during steady-state operation.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microsemi (now Microchip). The series covers voltages from 2.4 V to 200 V in various tolerances. The 1N5272 variant specifically targets the 110 V segment of this extensive lineup.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5272 without the TR suffix for bulk packaging, or the 1N5272B for tighter ±5% tolerance requirements. Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package.
