1N5384E3/TR8

Overview

The Microsemi Corporation 1N5384E3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, providing voltage regulation at a nominal Zener voltage of 160 V with a ±5% tolerance. It features a T-18 axial-lead plastic encapsulated package and operates within a temperature range of -65°C to +150°C. The device has a maximum reverse current of 0.5 µA and a dynamic impedance of 350 ohms. RoHS compliant, it includes tape and reel packaging options.

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 applications
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring 160 V reference
• High power dissipation environments with adequate heat sinking
• Surge protection applications utilizing high specified maximum current capabilities

Procurement Notes

Verify that the specific suffix 'e3' confirms RoHS compliance and lead-free terminations as documented in the datasheet. Confirm the 'TR8' designation aligns with the required tape and reel packaging format. Ensure the component meets the necessary military equivalent screening levels if applicable, as standard versions differ from screened prefixes.

Selection Notes

Select this component when a 160 V Zener voltage with ±5% tolerance is required for 5-watt power dissipation. Consider the T-18 axial-lead package for through-hole mounting. Evaluate thermal resistance requirements, noting the junction-to-lead value of 25°C/W, to ensure proper heat sinking for steady-state operation.

Part Context

This part belongs to the 1N5333B thru 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide selection of voltages from 3.3 to 200 volts. The 'e3' suffix indicates RoHS compliance, while the 'TR8' suffix specifies the tape and reel packaging option.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes to the base part number.
