1N5371E3/TR8

Overview

The Microchip Technology 1N5371E3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 60V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA at 43V and a dynamic impedance of 40 ohms. The device utilizes an axial-lead T-18 package and includes a tape-and-reel option for automated assembly.

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 suitable for through-hole applications

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 configuration against official datasheets to confirm tolerance and packaging options. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation for the component batch prior to procurement.

Selection Notes

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

Part Context

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

Replacement Considerations

Equivalent parts include other 5W Zener diodes with a 60V nominal voltage and similar tolerance ratings. Verify thermal resistance and package dimensions match the existing design constraints before substitution.
