1N5384CE3/TR8

Overview

The Microsemi Corporation 1N5384CE3/TR8 is a silicon planar Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 160 V with a tight tolerance of ±2%. The device features a maximum power dissipation of 5.0 watts and operates within a temperature range of -65°C to +150°C. Packaged in a T-18 axial lead case, it includes an e3 suffix indicating RoHS compliance and TR8 suffix denoting tape and reel packaging.

Feature Summary

• Provides precise voltage regulation with ±2% tolerance for high-stability applications
• Capable of handling high surge stresses and maximum DC currents when adequately heat sunk
• Features flexible axial-lead mounting terminals suitable for through-hole assembly
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Applications

• Voltage regulation in broad operating current and temperature ranges
• High-power circuit protection requiring robust surge withstand capability
• Precision reference circuits utilizing tight voltage tolerances

Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and 'TR8' specifies tape and reel packaging. Confirm the 'C' suffix indicates the required ±2% voltage tolerance. Ensure the component matches the T-18 package dimensions and verify the manufacturer origin as Microsemi Corporation or authorized successor entities.

Selection Notes

Select this component when a 160 V Zener voltage with ±2% precision is required. The 5-watt power rating necessitates adequate thermal management via heat sinking or PCB copper pads. Consider the T-18 axial package for through-hole designs and ensure the operating environment falls within the specified -65°C to +150°C range.

Part Context

This part belongs to the 1N5333B through 1N5388B series of 5.0-watt silicon 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 low thermal resistance and high current operation.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available from the same manufacturer. Verify pinout compatibility and thermal performance differences when transitioning between axial lead and surface mount packages.
