1N5344A/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5344A/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial-lead T-18 package with TR12 tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 8.2 volts with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 1.5 ohms at a test current of 150 mA. It withstands high surge stresses and includes a void-free transfer molded thermosetting epoxy body.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses due to low thermal resistance design
• Features flexible axial-lead mounting terminals for secure installation
• Moisture classification Level 1 requiring no dry pack storage

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance and packaging details. Ensure compatibility with RoHS requirements if applicable, as standard versions may differ from e3 compliant variants. Confirm lead availability and manufacturing status directly with the manufacturer or authorized distributors prior to procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating and an 8.2-volt regulation point are required. Consider the ±10% tolerance specification for applications allowing wider voltage variance. Evaluate thermal management needs based on the junction-to-lead thermal resistance characteristics provided in the datasheet.
