1N5386C/TR12

Overview

The Microsemi Corporation 1N5386C/TR12 is a silicon Zener diode with a nominal voltage of 180V and a tolerance of ±2%. It features a maximum power dissipation of 5W, a maximum dynamic impedance of 430 Ohms, and a maximum reverse current of 0.5µA at 130V. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial leaded plastic package.

Feature Summary

• Provides tight voltage regulation with ±2% tolerance for precision applications
• Capable of handling high surge stresses and steady-state power dissipation up to 5 watts
• Features a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards

Applications

• Voltage regulation in broad operating current and temperature ranges
• High reliability circuits requiring military equivalent screening levels
• Power supply designs utilizing adequate heat sinking for high DC currents

Procurement Notes

Verify the specific suffix 'TR12' indicates tape and reel packaging per EIA-296 standards. Confirm RoHS compliance status as standard parts may vary by manufacturing date. Ensure the component matches the JEDEC registered 1N5386B series specifications for electrical characteristics and physical dimensions before integration into production.

Selection Notes

Select this component when a precise 180V reference is required with minimal deviation. The C suffix ensures tighter tolerances compared to standard B or A variants. Consider the thermal resistance of 25°C/W junction-to-lead for proper heat sinking design to maintain performance under maximum load conditions.

Part Context

This part belongs to the 1N5333-5388B JEDEC registered series of axial-leaded 5.0 watt Zeners. The series offers voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These plastic encapsulated devices have a Level 1 moisture classification and are available in military screening prefixes like MQ, MX, or MV.

Replacement Considerations

Equivalent parts include 1N5386B (±5% tolerance) and 1N5386A (±10% tolerance). Surface mount equivalents are SMBJ5386B or SMBG5386B. Verify that replacement components match the 5W power rating and T-18 package dimensions for mechanical compatibility.
