Overview
The Microsemi Corporation 1N5386CE3/TR8 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 180 V with a tight tolerance of ±2%. The device operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 430 Ohms, a maximum reverse current of 0.5 µA, and a maximum regulator current of 26.4 mA.
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 standard through-hole applications
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage sources in measurement equipment
Procurement Notes
Verify that the ordering suffix 'e3' confirms RoHS compliance and 'TR8' indicates tape and reel packaging. Confirm the specific part number matches the required 180V Zener voltage and ±2% tolerance. Ensure the manufacturer designation aligns with Microsemi specifications before finalizing procurement orders.
Selection Notes
Select this component when a precise 180V reference is required with tight tolerance constraints. The 5-watt power dissipation rating supports high DC currents provided adequate heat sinking is utilized. Verify thermal resistance requirements against the application's ambient temperature conditions to ensure reliable operation within the specified limits.
Part Context
This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi. The series offers a wide selection of voltages from 3.3V to 200V. The 'C' suffix specifically denotes a ±2% voltage tolerance, distinguishing it from standard B or A suffix variants.
Replacement Considerations
Direct replacements must match the 180V Zener voltage, 5W power rating, and ±2% tolerance. Verify that alternative packages maintain the T-18 form factor and compatible thermal characteristics.
