1N5367A/TR8

Overview

The Microchip Technology 1N5367A/TR8 is a silicon unidirectional voltage regulator diode belonging to the JEDEC registered 1N5333B through 1N5388B series. It provides a nominal Zener voltage of 43 V with a standard tolerance of ±10%, indicated by the 'A' suffix. The device features a maximum power dissipation of 5.0 watts at 25°C and operates within a temperature range of -65°C to +150°C. Packaged in a T-18 axial lead format, it includes a TR suffix for tape and reel delivery.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 5-watt power handling
• Protection against high surge stresses in electronic systems
• Applications necessitating ESD resistance compliant with MIL-STD-750 Method 1020

Procurement Notes

Verify the specific part number suffixes to confirm the exact voltage tolerance and packaging configuration. Ensure that the procurement documentation aligns with the manufacturer's latest datasheet revisions. Confirm compliance requirements such as RoHS status if applicable to the intended deployment environment.

Selection Notes

Select this component when a 43 V Zener voltage with ±10% tolerance is required. Consider the 5-watt power dissipation capability and the thermal resistance characteristics for adequate heat sinking. Verify that the T-18 package dimensions fit the available board space and that the axial lead style matches the assembly process.

Part Context

This component is part of the broader 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi, now part of Microchip Technology. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments.

Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. RoHS compliant versions can be identified by adding the e3 suffix to the part number.
