1N5388AE3/TR13

Overview

The Microsemi Corporation 1N5388AE3/TR13 is a silicon 5.0-watt Zener diode with a nominal voltage of 200 V and a ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA at 144 V and a dynamic impedance of 480 Ω. The component utilizes an axial-lead T-18 package and includes a tape-and-reel option.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses while maintaining minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation

Applications

• Voltage regulation circuits requiring high power dissipation
• Surge protection applications utilizing high specified maximum current capabilities
• Equipment requiring robust performance under high thermal stress conditions

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance levels and compliance standards. Confirm that the e3 designation aligns with required RoHS specifications and ensure the TR suffix matches the intended reel packaging requirements for automated assembly processes.

Selection Notes

Select this component when a 200 V regulation point is required alongside a 5 W power rating. Ensure adequate heat sinking is provided to maintain junction temperatures within limits, as steady-state power dissipation depends heavily on lead length or PCB copper pad dimensions during operation.

Part Context

This device belongs to the JEDEC registered 1N5333 through 1N5388B series of axial-leaded 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts, providing engineers with standardized options for various high-power voltage regulation and clamping applications.

Replacement Considerations

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