1N5367BE3/TR8

Overview

The Microchip Technology 1N5367BE3/TR8 is a silicon Zener diode with a nominal voltage of 43V and a power dissipation rating of 5W. It features a ±5% tolerance, indicated by the 'B' suffix, and RoHS compliance via the 'e3' suffix. The device utilizes a T-18 axial lead package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 20 Ω at a test current of 30 mA and a maximum reverse leakage current of 0.5 µA.

Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole applications
• Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020

Applications

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

Procurement Notes

Verify the specific suffixes on the component marking against the datasheet nomenclature to confirm tolerance and compliance status. Ensure the ordering part number matches the required tape and reel configuration if automated assembly is intended. Cross-reference the manufacturer's discontinuation notices or PCNs to confirm long-term availability before finalizing procurement plans.

Selection Notes

Select this component when a 43V regulation point is required with a 5W power handling capability. The T-18 package offers low thermal resistance suitable for heat sinking. Consider the ±5% tolerance for general regulation tasks. Verify that the operating environment stays within the specified -65°C to +150°C range and that adequate heat sinking is provided for steady-state operation near maximum ratings.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series provides a wide selection of voltages from 3.3V to 200V. The 'e3' designation indicates RoHS compliance, while the 'TR' suffix specifies tape and reel packaging. These diodes are designed for robust performance in demanding environments.

Replacement Considerations

Equivalent parts within the same series include 1N5367B (standard tolerance) or 1N5367C (±2% tolerance). Surface mount equivalents are available as SMBJ5367B or SMBG5367B. Verify pinout compatibility and thermal requirements when substituting.
