1N5344BE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N5344BE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 8.2 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 10 µA at 5.9 V. Packaged in an axial T-18 case with RoHS compliant e3 plating, it supports tape and reel delivery via the TR suffix.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole integration
• Constructed with void-free transfer molded thermosetting epoxy meeting UL94V-0

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 component authenticity against official Microchip documentation. Confirm that the specific ordering suffixes correspond to the required electrical tolerances and packaging formats. Ensure compliance with environmental standards such as RoHS requirements before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required for high-current applications. The 8.2 V nominal voltage and ±5% tolerance suit general-purpose regulation tasks. Consider thermal management strategies, as steady-state power depends on adequate heat sinking or FR4 PC board mounting conditions.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V in a robust axial-lead package designed for high-power applications requiring reliable voltage clamping.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Verify pinout compatibility and thermal performance characteristics when transitioning between axial leaded and surface mount packages.
