1N5387/TR12

Overview

The Microsemi Corporation 1N5387/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 190 V and ±5% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 500 nA at 137 V and a dynamic impedance of 450 ohms. The component utilizes an axial-lead T-18 package and includes a TR suffix for tape and reel packaging.

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 suitable for through-hole applications

Applications

Voltage regulation circuits requiring high power dissipation
Surge protection systems utilizing robust thermal resistance design
High maximum DC current operations with adequate heat sinking

Procurement Notes

Verify the specific ordering suffixes against official Microsemi documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with JEDEC registration standards and check for military equivalent screening levels if required by the application specifications.

Selection Notes

Select this component for applications demanding 5-watt power dissipation capabilities and wide voltage selection up to 200 volts. Consider the low thermal resistance design for high current operations and verify that the T-18 axial lead package aligns with the mechanical constraints of the target circuit board layout.

Part Context

This device belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a comprehensive selection of voltages from 3.3 to 200 volts with various tolerance options identified by specific suffix letters on the part number.
