1N5372/TR8

Overview

The Microchip Technology 1N5372/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 60 V. It features a maximum dynamic impedance of 40 ohms and a maximum reverse current of 0.5 µA at 43 V. The device operates within a temperature range of -65°C to +150°C and utilizes an axial-lead T-18 package.

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

Applications

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

Procurement Notes

Verify the specific suffix 'TR8' against official manufacturer documentation to confirm tape-and-reel packaging compliance. Confirm RoHS status and screening levels, as these attributes depend on the exact ordering designation provided by the supplier.

Selection Notes

Select this component when a 60 V regulation point is required with a 5 W power dissipation capacity. Ensure adequate heat sinking is available to maintain junction temperatures within the specified limits during operation.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series covers a wide voltage range from 3.3 V to 200 V, offering various tolerance options identified by suffix letters such as B, C, or D.

Replacement Considerations

Consult official datasheets for cross-reference data. Verify that any substitute part matches the 60 V nominal voltage, 5 W power rating, and T-18 package dimensions.
