1N5384BE3/TR12

Overview

The Microsemi Corporation 1N5384BE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, designed for voltage regulation applications. It features a nominal Zener voltage of 160 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 350 Ohms at an 8 mA test current and a maximum reverse leakage current of 500 nA. The component is RoHS compliant due to the 'e3' suffix and is supplied in tape and reel packaging as specified by the 'TR12' designation.

Feature Summary

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

Applications

• Voltage regulation circuits requiring high power dissipation capabilities
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial electronic systems

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'B' indicates ±5% voltage tolerance, 'e3' confirms RoHS compliance, and 'TR12' specifies tape and reel packaging. Confirm the manufacturer origin, as this part was originally produced by Microsemi before its acquisition by Microchip Technology. Ensure the procurement channel provides valid traceability documentation for the component's manufacturing history and quality standards.

Selection Notes

Select this component when a 160 V Zener voltage with ±5% precision is required for high-power applications up to 5 watts. Consider the T-18 axial package for through-hole mounting where adequate heat sinking is available to maintain performance within the -65°C to +150°C operating range. Evaluate the 350 Ohm dynamic impedance for suitability in circuits sensitive to current fluctuations.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by specific suffix letters. These plastic encapsulated diodes are designed for low thermal resistance operation and are available in military equivalent screening levels upon request.
