1N5227A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5227A/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 3.6 V with ±10% tolerance and a maximum reverse current of 24 µA at 1 V. It operates from -65°C to +175°C, has a thermal resistance of 250 °C/W junction-to-lead, and includes a tape-and-reel option indicated by the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features hermetically sealed glass axial-lead construction for durability
• Offers flexible mounting terminals compatible with standard through-hole processes

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the part number matches the exact JEDEC type and tolerance suffix required for your design. Confirm the presence of the TR suffix if reel packaging is needed. Ensure the manufacturer documentation aligns with the specific screening level or RoHS compliance status intended for your project.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V Zener voltage with 10% tolerance is required in a DO-35 package. Consider the 0.5 W power dissipation limit and the specified thermal resistance for proper heat management. Verify compatibility with existing board layouts designed for axial-leaded components.

Single Zener Diodes Part Context

This device belongs to the widely used 1N5221 through 1N5281B series of 0.5 W Zener diodes. The series covers voltages from 2.4 V to 200 V, offering various tolerance options identified by suffix letters. The 1N5227A specifically targets the lower end of the voltage spectrum within this extensive lineup.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5227 without the A suffix for 20% tolerance, or the 1N5227B for 5% tolerance. Surface mount equivalents are available as MLL5227A in the DO-213AA MELF package.
