Overview
The Microsemi 1N5384B/TR8 is a silicon Zener diode with a nominal voltage of 160V and ±5% tolerance. It features a 5W power dissipation rating at 25°C, operating temperatures from -65°C to +150°C, and a maximum dynamic impedance of 350 ohms. The device utilizes an axial-lead T-18 plastic package and includes the TR suffix for 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 voltage change versus current
- Features flexible axial-lead mounting terminals for versatile integration
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement systems
Procurement Notes
Verify that the part number includes the TR suffix to confirm tape and reel packaging configuration. Ensure the B suffix is present to guarantee the specified ±5% voltage tolerance. Confirm RoHS compliance status if required by assembly specifications. Cross-reference the manufacturer's latest documentation for any updates to mechanical dimensions or electrical characteristics prior to final procurement.
Selection Notes
Select this component when a 160V Zener reference with moderate precision is required. The 5W power rating supports high-current applications provided adequate heat sinking is implemented. Consider the thermal resistance values for PCB mounting scenarios. Evaluate the surge current capabilities against potential transient events in the target circuit design.
Part Context
This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt silicon Zener diodes. The series offers a wide voltage selection from 3.3V to 200V with various tolerance options. The 1N5384B specifically addresses the higher voltage end of the standard regulatory spectrum within this robust axial-leaded family.
Replacement Considerations
Equivalent parts include other manufacturers' 1N5384B variants. Verify pinout compatibility and thermal performance metrics before substitution. Surface mount equivalents such as SMBJ5384B are available but require different footprint considerations.
