1N5226A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5226A/TR is a 0.5 W glass axial-lead Zener diode in the DO-35 package, featuring a nominal voltage of 3.3 V with ±10% tolerance (suffix A). It operates within a temperature range of -65°C to +175°C 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 electronic systems
• General-purpose voltage regulation tasks

Single Zener Diodes Procurement Notes

Verify that the part number matches the specific manufacturer's datasheet specifications exactly. Confirm the presence of the 'TR' suffix indicates tape-and-reel packaging rather than bulk supply. Ensure the 'A' suffix corresponds to the required 10% voltage tolerance before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V Zener voltage with 10% tolerance is required. The DO-35 package suits through-hole designs needing robust thermal performance. Verify that the 0.5 W power dissipation rating meets the circuit's thermal requirements under expected operating conditions.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. Originally manufactured by Microsemi, these components are now part of Microchip Technology's portfolio following acquisition. The series provides a wide selection of voltages from 2.4 V to 200 V.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5226A variants in the DO-35 package. Surface mount equivalents like MLL5226A are available for different form factors. Verify electrical parameters match before substitution.
