1N5344A/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5344A/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 8.2 volts with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum reverse current of 10 µA and a dynamic impedance of 1.5 ohms.

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 through-hole integration

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply reference designs
• Protection against overvoltage conditions in industrial equipment

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet identifies Microsemi Scottsdale Division while the brand is listed as Microchip Technology. Confirm that the TR8 suffix corresponds to tape and reel packaging per EIA-296 standards. Ensure compatibility with RoHS requirements if applicable to the project specifications.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and an 8.2-volt regulation point are required. The A suffix indicates a standard 10% voltage tolerance suitable for general-purpose applications. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking calculations to maintain operation within the specified temperature limits.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes. These devices are designed for high-power applications and offer a wide selection of voltages from 3.3V to 200V. The series includes various tolerance options and screening levels for military equivalents.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5343B and 1N5345B. Verify that substitute components match the 5-watt power dissipation and T-18 package dimensions.
