1N5350BE3/TR8

Overview

The Microchip Technology 1N5350BE3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 13 V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum dynamic impedance of 2.5 Ω and a reverse current of 1.0 µA at 9.4 V. The device utilizes an axial-lead T-18 package and includes a TR suffix for tape-and-reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage changes versus current
• Features flexible axial-lead mounting terminals for secure installation

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify the component's authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the e3 suffix and ensure the tape-and-reel packaging matches project requirements. Validate electrical parameters such as Zener voltage and impedance before integration into designs.

Selection Notes

Select this component for applications requiring robust 5-watt power dissipation and wide thermal stability. Ensure adequate heat sinking is provided to maintain performance within specified limits. Verify that the axial lead configuration fits the intended PCB layout constraints.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by specific suffix letters on the part number.

Replacement Considerations

Direct surface mount equivalents are available as SMBJ5350B or SMBG5350B. Other manufacturers may offer compatible parts, but verify pinout and electrical characteristics match the original specifications.
