1N5375/TR8

Overview

The Microsemi Corporation 1N5375/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial-lead T-18 plastic package. It provides voltage regulation at a nominal Zener voltage of 82V with a ±5% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum power dissipation of 5 watts at 25°C lead temperature. The 'TR' suffix indicates tape and reel packaging compliant with EIA-296 standards.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features low thermal resistance design for high maximum DC current operation
• Withstands high surge stresses and is nonsensitive to electrostatic discharge
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation over wide operating current and temperature ranges
• High surge stress environments requiring robust protection
• Applications utilizing flexible axial-lead mounting terminals

Procurement Notes

Verify that the ordering suffix TR corresponds specifically to tape and reel packaging as defined by EIA-296 standards. Confirm the B suffix indicates the standard ±5% voltage tolerance. Ensure the component matches the specified T-18 axial-lead plastic encapsulation and check for any specific military screening prefixes if required for the application.

Selection Notes

Select this component when a 5-watt power rating and 82V regulation are required. Consider the T-18 package for through-hole applications needing flexible axial leads. Evaluate thermal management requirements, as steady-state power dissipation depends on adequate heat sinking or FR4 PC board copper pad specifications to maintain performance within the rated limits.

Part Context

This part belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a voltage selection from 3.3V to 200V with various tolerance options identified by suffix letters. These devices are designed for applications requiring reliable voltage regulation and high surge capability in a durable plastic encapsulated form factor.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. RoHS compliant versions can be found by adding the e3 suffix to the base part number.
