1N5383E3/TR12

Overview

The Microsemi Corporation 1N5383E3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial-lead T-18 plastic package with tape and reel packaging. It provides a nominal Zener voltage of 150V with a standard ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum power dissipation of 5 watts at 25°C. Electrical characteristics include a maximum dynamic impedance of 330 ohms and a maximum reverse current of 0.5 µA.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for versatile circuit integration
• Withstands high surge stresses without damage
• RoHS compliant construction available via specific ordering suffixes

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement equipment

Procurement Notes

Verify that the component matches the exact part number 1N5383E3/TR12 to ensure correct voltage rating and RoHS compliance status. Confirm the presence of the TR suffix indicates tape and reel packaging rather than bulk or individual units. Check manufacturer documentation for any recent product change notices or end-of-life announcements affecting availability.

Selection Notes

Select this component when a 150V Zener voltage with ±10% tolerance is required in a 5-watt axial leaded package. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits. Consider the ESD sensitivity and surge current capabilities relative to the specific application environment.

Part Context

This device belongs to the Microsemi 1N5333-5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. The e3 suffix denotes RoHS compliance, while the TR suffix specifies tape and reel packaging for automated assembly processes.

Replacement Considerations

Consult official Microsemi documentation for verified substitute part numbers. Cross-referencing should be performed carefully to match voltage, power dissipation, and package type specifications.
