1N5373BE3/TR8

Overview

The Microchip Technology 1N5373BE3/TR8 is a silicon Zener diode with a nominal voltage of 68 V and a tolerance of ±5%. It features a maximum power dissipation of 5 W at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes the e3 suffix for RoHS compliance and TR8 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 voltage change versus current
• Features flexible axial-lead mounting terminals suitable for through-hole applications

Applications

• Voltage regulation in electronic circuits
• Protection against transient voltage spikes
• Reference voltage sources in power supplies

Procurement Notes

Verify the specific ordering suffixes to confirm the exact configuration. The 'e3' suffix indicates RoHS compliance, while 'TR8' specifies the tape and reel packaging format. Ensure compatibility with existing assembly processes regarding lead length and soldering temperatures before procurement.

Selection Notes

Select this component when a 68 V Zener voltage with ±5% tolerance is required. Consider the 5 W power rating and thermal resistance characteristics for adequate heat sinking. Verify that the axial-lead T-18 package fits the design constraints and that the operating temperature range meets system requirements.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 'B' suffix denotes a standard voltage tolerance of ±5%, distinguishing it from other tolerance options available in the family.

Replacement Considerations

Equivalent parts include the 1N5373B without the e3 or TR8 suffixes for different packaging or compliance needs. Surface mount equivalents such as the SMBJ5373B are available if board space requires a different form factor.
