1N5387AE3/TR13

Overview

The Microsemi Corporation 1N5387AE3/TR13 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, housed in an axial T-18 package with RoHS-compliant matte-tin plating. It provides a standard voltage of 190V with a ±10% tolerance (A suffix). Key electrical parameters include a maximum dynamic impedance of 450 ohms at 25°C, a reverse current of 0.5 µA tested at 137V, and a maximum regulator current of 25A when adequately heat sunk. The device operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and features minimal changes of voltage versus current
• Flexible axial-lead mounting terminals for versatile integration
• Moisture classification Level 1 requiring no dry pack

Applications

• Voltage regulation circuits
• High power dissipation applications requiring adequate heat sinking
• Surge stress protection environments

Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and matte-tin plating. Confirm the 'TR13' suffix indicates tape and reel packaging per EIA-296 standards. Ensure the 'A' suffix matches the required ±10% voltage tolerance. Cross-reference the specific revision date on the datasheet to ensure compatibility with current manufacturing specifications.

Selection Notes

Select this component for applications requiring a 190V Zener voltage with a 5W power rating. The axial leaded T-18 package is suitable for through-hole mounting. Consider the thermal resistance of 25°C/W junction-to-lead when designing heat sinking solutions. Verify that the operating environment does not exceed the specified maximum junction temperature limits.

Part Context

This component belongs to the 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a voltage selection from 3.3V to 200V. These devices are designed for plastic encapsulation meeting UL94V-0 standards and offer various screening levels for military equivalents.

Replacement Considerations

Surface mount equivalents such as SMBJ5387 or SMBG5387 are available within the same product family. Other parts in the 1N5333-5388B series can be considered if different voltage tolerances or values are required.
