1N5344AE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N5344AE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 8.2 V with a ±10% tolerance (A suffix). The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a maximum dynamic impedance of 1.5 Ohms at a test current of 150 mA, a maximum reverse leakage current of 10 µA at 5.9 V, and a maximum regulator current of 580 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile integration
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in industrial equipment

Single Zener Diodes Procurement Notes

Verify the component origin as this part originates from the Microsemi Scottsdale Division, which was acquired by Microchip Technology. Confirm that the 'e3' suffix indicates RoHS compliance and the 'TR13' suffix denotes tape and reel packaging per EIA-296 standards. Ensure the specific A suffix corresponds to the required ±10% voltage tolerance for your design specifications.

Single Zener Diodes Selection Notes

Select this component when a 5-watt axial Zener diode with an 8.2 V nominal rating is required. The A suffix specifically denotes a ±10% tolerance; choose B, C, or D suffixes if tighter tolerances are needed. Consider the thermal resistance of 25 °C/W junction-to-lead for heat sinking requirements. Verify compatibility with the T-18 package dimensions for PCB layout.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3 V to 200 V. The 1N5344 variant specifically targets the 8.2 V regulation point. Surface mount equivalents are available in SMBJ and SMBG packages within the same product family.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBG5344A or SMBJ5344A are available from the same manufacturer. Other manufacturers producing JEDEC registered 1N5344 variants may serve as functional substitutes if electrical parameters match.
