1N5387B/TR12

Overview

The Microsemi Corporation 1N5387B/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 190 V and ±5% tolerance. It features a T-18 axial leaded plastic package and operates within a temperature range of -65°C to +150°C. The device has a maximum reverse current of 500 nA at 137 V, a dynamic impedance of 450 ohms, and a forward voltage of 1.2 V at 1 A. The TR12 suffix indicates tape and reel packaging.

Feature Summary

Provides stable voltage regulation across a broad operating current and temperature range
Withstands high surge stresses and offers minimal changes in voltage versus current
Features flexible axial-lead mounting terminals for versatile installation
Moisture classification Level 1 requires no dry pack handling

Applications

Voltage regulation circuits requiring 190 V reference
High power dissipation applications with adequate heat sinking
Surge protection environments

Procurement Notes

Verify the component status as discontinued before procurement planning. Confirm that the TR12 suffix corresponds to the required tape and reel packaging format. Ensure compatibility with the specified T-18 through-hole package dimensions for your assembly process.

Selection Notes

Select this component for applications requiring a 190 V Zener voltage with tight ±5% tolerance. Consider the 5 W power rating and thermal resistance characteristics when designing heat sinking solutions. Verify that the axial lead configuration fits the mechanical constraints of the target enclosure.

Part Context

This part belongs to the JEDEC registered 1N5333-5388B series of 5.0 watt Zener diodes. The series covers voltages from 3.3 to 200 V. The 'B' suffix specifically denotes a standard voltage tolerance of plus or minus 5%. The device utilizes a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards.
