1N5376A/TR8

Overview

The Microsemi Corporation 1N5376A/TR8 is a silicon 5-watt Zener diode with an 87 V nominal voltage and ±10% tolerance. It operates within a temperature range of -65°C to +150°C, features a maximum reverse current of 500 nA at 63 V, and has a dynamic impedance of 75 Ohms. The component utilizes a T-18 axial lead 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 changes in voltage versus current
• Features flexible axial-lead mounting terminals suitable for through-hole applications

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High surge stress environments
• Applications necessitating wide temperature operation from -65°C to +150°C

Procurement Notes

Verify the specific suffix 'TR8' confirms the tape and reel packaging format as documented. Confirm that the 'A' designation strictly corresponds to the ±10% voltage tolerance specified in the datasheet. Ensure the procurement matches the JEDEC registered series requirements and check for any RoHS compliance status if required by the application specifications.

Selection Notes

Select this component when a 5-watt power rating and 87 V regulation are required. The ±10% tolerance suits general-purpose applications where tighter precision is unnecessary. Consider the T-18 package dimensions and thermal resistance characteristics for adequate heat sinking during design integration.
