1N5381CE3/TR13

Overview

The Microsemi Corporation 1N5381CE3/TR13 is a silicon Zener diode with a nominal voltage of 130 V and a power dissipation rating of 5.0 watts at 25 °C. It features a T-18 axial lead package and operates within a temperature range of -65 °C to +150 °C. The device has a maximum dynamic impedance of 190 ohms, a test current of 10 mA, and a reverse leakage current of 0.5 µA at 93.6 V. Voltage tolerance is ±2%, and it includes RoHS compliance indicated by the e3 suffix.

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 for through-hole applications
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Applications

• Voltage regulation in electronic circuits
• High DC current operation with adequate heat sinking
• Surge stress protection applications

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm exact electrical tolerances and screening levels. Confirm RoHS compliance status and packaging options such as tape and reel availability directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a 130 V Zener voltage with tight ±2% tolerance is required. Ensure the application supports the 5-watt power dissipation capability and provides sufficient thermal management. Verify that the T-18 axial package fits the board layout constraints and that the operating temperature range meets system requirements.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts. The 'e3' suffix indicates RoHS compliant devices, while the 'TR' suffix denotes tape and reel packaging options available for automated assembly processes.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B.
