1N5378E3/TR13

Overview

The Microsemi Corporation 1N5378E3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 100 V with a ±10% tolerance, indicated by the 'A' suffix. The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 90 Ohms at a test current of 12 mA, a maximum reverse leakage current of 500 µA at 72 V, and a maximum regulator current of 47.5 A when adequately heat sunk.

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 versatile integration
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High reliability applications utilizing MIL-PRF-19500 screening options
• Surge protection environments due to high surge current capability

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm exact tolerance and packaging specifications. Confirm RoHS compliance status and lead material (tin-lead or annealed matte-tin) as required by the assembly process. Ensure adequate thermal management is designed into the system to support the specified 5-watt power dissipation rating during operation.

Selection Notes

Select this component for applications requiring a 100 V Zener reference with ±10% tolerance. Consider the T-18 axial package for through-hole mounting. Evaluate thermal resistance requirements based on the intended mounting method, as steady-state power dissipation varies significantly between free-air and FR4 PCB mounting configurations.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a voltage selection from 3.3 to 200 volts. The 'e3' suffix indicates RoHS compliance, while the 'TR' suffix denotes tape and reel packaging per EIA-296 standards.

Replacement Considerations

Surface mount equivalents are available in the SMBJ5333-SMBJ5388B and SMBG5333-SMBG5388B series.
