1N5386CE3/TR12

Overview

The Microsemi Corporation 1N5386CE3/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 180 V with a tight tolerance of ±2%, indicated by the 'C' 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 reverse current of 0.5 µA and a maximum dynamic impedance of 430 Ohms. The component is RoHS compliant, as denoted by the 'e3' suffix, and is supplied in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required

Applications

• Voltage regulation circuits requiring high power dissipation
• Protection against high surge stresses in electronic systems
• Applications necessitating operation at elevated temperatures up to 150°C

Procurement Notes

Verify the specific part number suffixes to confirm tolerance and compliance status. The 'C' suffix indicates a ±2% voltage tolerance, while 'e3' confirms RoHS compliance. Ensure the 'TR' suffix matches the required tape and reel packaging format. Cross-reference the manufacturer's official documentation for any recent product change notifications or discontinuance alerts associated with this component.

Selection Notes

Select this component when a 180 V Zener voltage with tight ±2% tolerance is required. The 5-watt power rating supports high DC currents provided adequate heat sinking is utilized. Consider the T-18 axial lead package for mechanical stability. Verify thermal resistance requirements against the application's ambient temperature conditions to ensure safe operation within the specified junction-to-lead limits.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 to 200 volts. Different tolerance levels are identified by specific suffix letters, such as B for ±5%, A for ±10%, C for ±2%, and D for ±1%. The devices are plastic encapsulated with void-free transfer molded thermosetting epoxy bodies meeting UL94V-0 standards.

Replacement Considerations

Equivalent parts within the same series include 1N5386B (±5% tolerance) and 1N5386A (±10% tolerance). Military screening options are available with prefixes MQ, MX, or MV. Surface mount equivalents in SMBJ or SMBG packages may be considered if form factor changes are acceptable.
