1N5371B/TR8

Overview

The Microchip Technology 1N5371B/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 60V and ±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 a T-18 axial lead package and includes a tape and reel option indicated by the TR suffix.

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 versatile integration

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify that the specific part number matches the required electrical characteristics and packaging format. Confirm RoHS compliance status as standard versions may differ from e3 variants. Ensure the TR suffix aligns with automated assembly requirements. Cross-reference datasheet specifications against design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 60V regulation point is required with ±5% precision. Consider the 5W power dissipation capability and thermal resistance limits during circuit design. Verify compatibility with existing PCB layouts due to the T-18 package dimensions. Evaluate thermal management needs based on the specified junction-to-lead and junction-to-ambient resistance values.

Part Context

This component belongs to the JEDEC registered 1N5333 through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 'B' suffix specifically denotes a standard voltage tolerance of plus or minus 5%. The 'TR' suffix indicates availability in tape and reel packaging for automated processing.

Replacement Considerations

Equivalent parts include other 5W Zener diodes with 60V nominal voltage and ±5% tolerance. Verify package compatibility and thermal performance when substituting. Check manufacturer-specific screening levels if military equivalents are required.
