1N5381AE3/TR13

Overview

The Microsemi Corporation 1N5381AE3/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 e3 plating. It provides voltage regulation at a nominal Zener voltage of 130V with a ±10% tolerance (A suffix). The device operates within a temperature range of -65°C to +150°C and features a maximum reverse current of 500µA at 93.6V. It includes tape-and-reel packaging options for automated assembly.

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 suitable for various PCB configurations
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation circuits requiring 5W power dissipation
• High DC current applications with adequate heat sinking
• General purpose electronic equipment utilizing axial lead components

Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and the 'TR' suffix to ensure tape-and-reel packaging. Confirm the 'A' designation matches the required ±10% voltage tolerance. Cross-reference the manufacturer's latest datasheet for any updates regarding military screening prefixes or specific thermal derating requirements before finalizing procurement orders.

Selection Notes

Select this component when a 130V Zener voltage with ±10% tolerance is required in a 5W axial package. Ensure the application allows for sufficient heat sinking to maintain operation below the maximum junction temperature. Consider surface mount equivalents like SMBJ5381 if board space constraints preclude the use of through-hole T-18 packages.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V. The 1N5381 variant specifically targets the 130V regulation segment within this extensive lineup of plastic encapsulated, JEDEC registered components.

Replacement Considerations

Surface mount equivalents are available as SMBJ5381 or SMBG5381. For tighter tolerances, variants with C (±2%) or D (±1%) suffixes exist within the same series.
