1N5367CE3/TR8

Overview

The Microchip Technology 1N5367CE3/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333B to 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 43 V with a tight tolerance of ±2%, indicated by the C suffix. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 0.5 µA tested at 31 V. Packaged in an axial-lead T-18-2 case, it supports tape and reel mounting via the TR8 suffix.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• RoHS compliant construction available with e3 suffix designation

Applications

• Voltage regulation circuits requiring high power dissipation
• Power supply reference designs
• Protection against overvoltage conditions

Procurement Notes

Verify that the component matches the specific 43 V Zener voltage and ±2% tolerance requirements. Confirm the presence of the e3 suffix for RoHS compliance and the TR8 suffix for tape and reel packaging. Ensure the procurement source is authorized to handle discontinued or legacy Microsemi/Microchip products.

Selection Notes

Select this component when a 5-watt power rating and precise ±2% voltage tolerance are required. The axial lead configuration suits applications needing robust mechanical mounting. Consider thermal derating curves if ambient temperatures exceed standard limits or if heat sinking is not utilized.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series covers a wide voltage range from 3.3 V to 200 V. The 1N5367 variant specifically targets the 43 V regulation point within this lineup.
