Overview
The Microsemi Corporation 1N5386A/TR8 is a silicon Zener diode with a nominal voltage of 180 V and a ±10% tolerance. It features a maximum power dissipation of 5.0 W at 25°C, operating temperatures from -65°C to +150°C, and a maximum dynamic impedance of 430 ohms. The device utilizes a T-18 axial leaded package and is supplied in tape and reel format.
Feature Summary
- Provides stable voltage regulation across broad operating current and temperature ranges
- Withstands high surge stresses while maintaining minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for versatile through-hole integration
Applications
- Voltage regulation over wide operating current and temperature ranges
- High surge stress environments requiring robust voltage clamping
- Circuits utilizing flexible axial-lead mounting terminals
Procurement Notes
Verify the specific suffix 'TR8' against official documentation to confirm tape and reel packaging specifications. Confirm RoHS compliance status as standard variants may differ. Validate that the A suffix correctly denotes the required ±10% voltage tolerance for your design parameters before procurement.
Selection Notes
Select this component when a 180 V Zener reference with ±10% tolerance is required. Ensure adequate heat sinking is provided to support the 5.0 W power dissipation rating. Verify that the T-18 axial lead package fits the PCB layout constraints and that the specified thermal resistance meets the system's ambient temperature requirements.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0 watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. Different tolerances are identified by specific suffix letters on the part number, allowing for precise selection based on circuit accuracy needs.
Replacement Considerations
Surface mount equivalents are available as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B. RoHS compliant versions are available by adding the e3 suffix to the part number.
