1N5376BE3/TR13

Overview

The Microsemi Corporation 1N5376BE3/TR13 is a silicon Zener diode with a nominal voltage of 87 V and a maximum power dissipation of 5 W. It features a ±5% tolerance, indicated by the 'B' suffix, and operates within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes RoHS compliance via the 'e3' suffix. Electrical characteristics include a test current of 15 mA, a maximum dynamic impedance of 75 Ohms, and a maximum reverse current of 0.5 µA at 63 V.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 5 W power handling
• High reliability electronic systems
• Surge protection applications

Procurement Notes

Verify that the part number matches the specific B suffix for ±5% tolerance and e3 suffix for RoHS compliance. Confirm the TR13 designation indicates tape and reel packaging per EIA-296 standards. Ensure the component meets MIL-PRF-19500 requirements if military screening is necessary, as standard versions may differ from screened equivalents.

Selection Notes

Select this component for applications requiring a precise 87 V reference with tight ±5% tolerance. Consider the 5 W power rating and thermal resistance when designing heat sinking solutions. Verify compatibility with existing circuit layouts due to the T-18 axial lead form factor and ensure operation remains within the specified -65°C to +150°C temperature limits.

Part Context

This component belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5 Watt Zener diodes. The series provides a wide selection of voltages from 3.3 V to 200 V. The 1N5376BE3/TR13 specifically represents the 87 V variant within this family, offering robust performance in plastic encapsulated axial packages suitable for general-purpose and high-reliability electronics.

Replacement Considerations

Equivalent parts include 1N5376B without the e3 or TR suffixes for different packaging or compliance needs. Surface mount alternatives such as SMBJ5376B or SMBG5376B are available for space-constrained designs. Verify that any substitute maintains the required 5 W power dissipation and ±5% voltage tolerance.
