Overview
The Microsemi 1N5381AE3/TR8 is a silicon Zener diode with a nominal voltage of 130V and ±10% tolerance. It features a 5W power dissipation rating at 25°C, operating within -65°C to +150°C. The device utilizes an axial-lead T-18 plastic package and includes the e3 suffix for RoHS compliance and 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 suitable for various board configurations
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 both the 'e3' suffix for lead-free RoHS compliance and the 'TR' suffix for tape-and-reel packaging. Confirm the manufacturer is Microsemi or an authorized distributor. Ensure the component matches the specified 130V Zener voltage and 5W power rating before procurement.
Selection Notes
Select this component when a 130V Zener reference with standard 10% tolerance is required. The 5W power rating allows for higher current operation compared to lower-power variants. The axial-lead format supports through-hole mounting, while the tape-and-reel option facilitates automated assembly processes.
Part Context
This component 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. The specific model integrates standard commercial screening with environmental compliance features.
Replacement Considerations
Equivalent parts include other 130V 5W Zener diodes from manufacturers such as Vishay or ON Semiconductor. Verify pinout compatibility and thermal resistance characteristics. Ensure replacement devices meet the same RoHS and moisture sensitivity level requirements.
