1N5223A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5223A/TR is a Zener diode with a nominal voltage of 2.7 V and a 10% tolerance, housed in a DO-35 glass axial-lead package. It dissipates up to 0.5 W at 25°C and operates from -65°C to +175°C. The device features a maximum reverse current of 30 μA at 1.9 V and a Zener impedance of 1300 Ω at 0.25 mA. It includes an 'e3' suffix for RoHS compliance and a 'TR' suffix for tape-and-reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range.
• Features flexible axial-lead mounting terminals suitable for through-hole applications.
• Inherently radiation hard per MicroNote 050 specifications.

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping circuits

Single Zener Diodes Procurement Notes

Verify the part number against official datasheets to confirm the specific suffixes. Ensure the 'A' suffix matches the required 10% tolerance and the 'TR' suffix aligns with reel-based procurement requirements. Cross-reference manufacturer documentation for any recent product change notifications or screening level updates.

Single Zener Diodes Selection Notes

Select this component when a 2.7 V Zener voltage with 10% tolerance is required in a DO-35 package. Consider the 0.5 W power dissipation limit and the -65°C to +175°C operating temperature range. Verify that the high Zener impedance (1300 Ω) meets the circuit's dynamic load requirements.

Single Zener Diodes Part Context

This component belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers voltages from 2.4 V to 200 V in standard 5% or 10% tolerances. These glass axial-leaded DO-35 Zeners are also available in various military screening levels by adding prefix identifiers.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5223B (5% tolerance), 1N5223C (2% tolerance), and 1N5223D (1% tolerance). Surface mount equivalents are available as MLL5223 variants in the DO-213AA MELF style package.

Single Zener Diodes FAQ

What does the 'A' suffix indicate on the 1N5223A?

The 'A' suffix identifies a standard voltage tolerance of plus/minus 10%.

Is the 1N5223A/TR RoHS compliant?

Yes, the 'e3' suffix indicates that the device is RoHS compliant.
