1N5386CE3/TR13

Overview

The Microsemi Corporation 1N5386CE3/TR13 is a silicon Zener diode with a nominal voltage of 180 V and a tolerance of ±2%. It operates within a power dissipation range of up to 5.0 watts at 25°C, featuring a maximum dynamic impedance of 430 ohms and a reverse current of 0.5 µA tested at 130 V. The device utilizes a T-18 axial lead package, supports an operating temperature from -65°C to +150°C, and includes a TR suffix indicating tape and reel packaging.

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

Applications

• Voltage regulation circuits requiring high specified maximum current
• Power supply designs utilizing adequate heat sinking for thermal management
• Electronic systems needing robust protection against high surge stresses

Procurement Notes

Verify the specific C suffix indicates a ±2% tolerance level when sourcing this component. Confirm that the TR suffix corresponds to the required tape and reel packaging format for automated assembly processes. Ensure the RoHS compliant e3 designation matches environmental compliance requirements for the intended manufacturing environment.

Selection Notes

Select this component for applications demanding precise voltage regulation with tight tolerances compared to standard B or A suffix variants. Consider the T-18 package dimensions and thermal resistance characteristics when designing the PCB layout. Evaluate the need for adequate heat sinking to support the 5-watt steady-state power dissipation rating during operation.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages ranging from 3.3 to 200 volts. These plastic encapsulated devices are designed for high reliability and feature moisture classification Level 1 without requiring dry pack storage.

Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available from the same manufacturer.
