1N5344E3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5344E3/TR12 is a silicon 5.0-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 standard tolerance of plus or minus 5 percent, indicated by the B 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 and a maximum reverse current of 10 microamperes.

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 through-hole applications
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

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 component authenticity against official Microchip Technology documentation before integration. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compliance with RoHS directives as indicated by the e3 suffix. Validate thermal management requirements based on the specified power dissipation ratings.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and 8.2-volt regulation are required. The B suffix ensures a tight 5 percent voltage tolerance suitable for precision applications. Consider the T-18 axial package for robust mechanical mounting. Evaluate thermal derating curves if ambient temperatures exceed standard limits.
