1N5384AE3/TR8

Overview

The Microsemi Corporation 1N5384AE3/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 160 V and a tolerance of ±10%. It features an axial-lead T-18 plastic package, operates within a temperature range of -65°C to +150°C, and has a maximum dynamic impedance of 350 ohms at a test current of 8.0 mA. The device includes RoHS compliance via the e3 suffix and tape-and-reel packaging indicated by the TR8 suffix.

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 through-hole integration
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement equipment

Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and lead-free terminations. Confirm the 'TR8' suffix indicates tape-and-reel packaging rather than bulk or individual units. Ensure the component matches the specific 160V rating and ±10% tolerance required for the design.

Selection Notes

Select this component when a 5-watt power dissipation capability is necessary for high-current applications. The T-18 package offers low thermal resistance for effective heat sinking. Verify that the ±10% tolerance aligns with circuit requirements, as tighter tolerances are available with different suffixes.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0-watt Zener diodes. The series covers a voltage selection from 3.3 to 200 volts. The 'A' suffix specifically denotes a ±10% voltage tolerance, distinguishing it from the standard ±5% B suffix devices.

Replacement Considerations

Equivalent parts include the 1N5384B (±5% tolerance) and military screened variants such as MQ1N5384A or MV1N5384A. Verify that replacement options maintain the same 5W power rating and T-18 package dimensions.

FAQ

What does the 'e3' suffix indicate?

The 'e3' suffix indicates that the device is RoHS compliant and utilizes lead-free annealed matte-tin plating on the terminals.

How is polarity identified on the device?

Polarity is indicated by a band on the cathode end. The diode must be operated with the banded end positive with respect to the opposite end.
