1N5385CE3/TR12

Overview

The Microsemi Corporation 1N5385CE3/TR12 is a silicon 5.0-watt Zener voltage regulator diode belonging to the JEDEC registered 1N5333-5388B series. It provides a nominal Zener voltage of 170 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 an axial lead T-18 package. The 'e3' suffix denotes RoHS compliance, while the 'TR12' suffix indicates tape and reel packaging.

Feature Summary

Provides stable voltage regulation across broad operating current and temperature ranges
Features flexible axial-lead mounting terminals for through-hole applications
Withstands high surge stresses and exhibits minimal voltage change versus current
Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

Voltage regulation in power supply circuits
Overvoltage protection systems
Reference voltage generation in electronic instrumentation

Procurement Notes

Verify that the ordering suffixes match the required specifications: 'C' for ±2% tolerance, 'e3' for lead-free/RoHS compliance, and 'TR12' for tape and reel packaging. Confirm the manufacturer designation as Microsemi Corporation or its successor entity. Ensure the component meets the specified thermal resistance and maximum ratings for the intended application environment.

Selection Notes

Select this component when a precise 170 V regulation point is required with tight tolerance. Consider the 5 W power dissipation capability and the need for adequate heat sinking to maintain performance at high DC currents. Verify compatibility with the T-18 axial lead package and tape and reel handling requirements for automated assembly processes.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5.0-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by specific suffix letters. These plastic encapsulated devices are designed for robust operation in demanding environments.
