1N5376BE3/TR8

Overview

The Microsemi Corporation 1N5376BE3/TR8 is a silicon 5-watt Zener diode with an 87 V nominal voltage and ±5% tolerance. It operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. The device includes a TR suffix for tape and reel packaging, ensuring RoHS compliance through the e3 designation.

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 suitable for various PCB layouts

Applications

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

Procurement Notes

Verify the specific ordering suffixes against official Microsemi documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing thermal management designs due to the 5W power dissipation rating. Confirm RoHS compliance status if required by project specifications.

Selection Notes

Select this component for applications requiring precise 87V regulation with tight ±5% tolerance. Consider the T-18 package dimensions and thermal resistance characteristics for adequate heat sinking. Evaluate the maximum steady-state power dissipation limits relative to the intended ambient operating conditions.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The B suffix indicates standard ±5% tolerance, while the e3 suffix denotes RoHS compliant materials.

Replacement Considerations

Equivalent parts include 1N5376B and 1N5376AE3. Verify that substitute components match the 87V Zener voltage, 5W power rating, and T-18 axial lead package form factor.
