1N5384CE3/TR12

Overview

The Microsemi Corporation 1N5384CE3/TR12 is a single silicon Zener diode with a nominal voltage of 160 V and a tolerance of ±2%. It features a maximum power dissipation of 5.0 W at 25°C, a test current of 8.0 mA, and a maximum reverse leakage current of 0.5 µA. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial leaded package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole applications

Applications

• Voltage regulation circuits requiring high power handling
• Surge protection systems
• High-current DC operation with adequate heat sinking

Procurement Notes

Verify the component matches the JEDEC registered 1N5384B series specifications. Confirm the presence of the e3 suffix indicates RoHS compliance and the TR12 suffix denotes tape and reel packaging. Ensure the manufacturer is identified as Microsemi or its successor entity, Microchip Technology, based on the official datasheet documentation.

Selection Notes

Select this component when a precise 160 V regulation point with tight ±2% tolerance is required. The 5-watt power rating supports high maximum DC currents provided sufficient thermal management is implemented. The wide operating temperature range makes it suitable for demanding industrial environments.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a voltage selection from 3.3 to 200 volts, utilizing specific suffix letters to identify voltage tolerances such as C for ±2%.

Replacement Considerations

Equivalent parts include other manufacturers' 1N5384C variants or the standard 1N5384B series if looser tolerance is acceptable. Verify that replacement components maintain the same T-18 package dimensions and 5-watt power dissipation capabilities.
