1N5344C/TR8

Single Zener Diodes Overview

The Microchip Technology 1N5344C/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 8.2 volts and a tight tolerance of plus or minus 2 percent. It operates within a temperature range of negative 65 degrees Celsius to positive 150 degrees Celsius. The device features a maximum reverse current of 10 microamperes at 5.9 volts, a dynamic impedance of 1.5 ohms, and a maximum regulator current of 5.7 amperes.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight plus or minus 2 percent tolerance
• Capable of handling high surge stresses and steady-state power dissipation up to 5 watts
• Features flexible axial-lead mounting terminals for through-hole applications

Single Zener Diodes Applications

• Voltage regulation in broad operating current ranges
• High current circuit protection requiring adequate heat sinking
• General purpose voltage reference applications

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets before procurement. Confirm that the TR8 designation aligns with required tape and reel specifications. Ensure compatibility with existing thermal management designs due to the 5-watt power rating. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Single Zener Diodes Selection Notes

Select this component when a stable 8.2-volt reference with high precision is required. The T-18 package supports high current operation provided sufficient heat sinking is implemented. Consider the low dynamic impedance for applications demanding minimal voltage variation under load changes.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt silicon Zener diodes. The C suffix specifically denotes a plus or minus 2 percent voltage tolerance, distinguishing it from standard B suffix devices which offer plus or minus 5 percent tolerance.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5344B for standard tolerance requirements. Verify pinout and thermal characteristics match the original design constraints before substitution.
