1N5384C/TR8

Overview

The Microsemi 1N5384C/TR8 is a silicon Zener diode with a nominal voltage of 160V and a ±2% tolerance. It features a 5W power dissipation rating, unidirectional polarity, and an axial lead T-18 package. The device operates within a temperature range of -65°C to +150°C and includes RoHS compliance via the e3 suffix.

Feature Summary

• Provides precise voltage regulation with tight manufacturing tolerances
• Capable of handling high surge stresses and steady-state currents
• Features flexible axial-lead mounting terminals for diverse applications

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation in electronic instrumentation

Procurement Notes

Verify the specific suffix configuration against the datasheet to ensure correct tolerance and compliance status. Confirm that the TR8 tape and reel packaging matches the intended automated assembly requirements. Cross-reference the manufacturer's current documentation for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.

Selection Notes

Select this component when a stable 160V reference with high precision is required. The ±2% tolerance makes it suitable for applications demanding tighter voltage control than standard commercial grades. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits during operation.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide voltage selection from 3.3V to 200V. The 'C' suffix specifically denotes a ±2% voltage tolerance, distinguishing it from standard B (±5%) or A (±10%) variants within the same power class.

Replacement Considerations

Equivalent parts include the 1N5384B for standard tolerance or military screened versions like MQ1N5384E3. Verify that substitute components match the 5W power rating and T-18 package dimensions to ensure physical compatibility.

FAQ
