Overview
The Microsemi 1N5380E3/TR8 is a silicon Zener diode with a nominal voltage of 120V and a maximum power dissipation of 5.0 watts at 25°C. It features a unidirectional configuration in an axial-lead T-18 plastic package. The device operates within a temperature range of -65°C to +150°C and has a thermal resistance of 25°C/W junction-to-lead. Electrical characteristics include a test current of 10mA, a maximum dynamic impedance of 170 ohms, and a maximum reverse current of 0.5µA.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and offers minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for versatile integration
- Compliant with RoHS standards and moisture classification Level 1
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage generation in measurement equipment
Procurement Notes
Verify the specific suffixes on the component marking to confirm tolerance class and compliance status. Ensure the ordering part number matches the required screening level and packaging format. Confirm that the supplier provides documentation verifying the JEDEC registration and material composition as specified in the manufacturer datasheet.
Selection Notes
Select this component when a 120V Zener reference with 5W power handling is required. Consider the ±5% tolerance inherent to the B suffix series. Evaluate thermal management requirements based on the 25°C/W junction-to-lead resistance. Verify compatibility with existing PCB footprint dimensions for the T-18 axial package.
Part Context
This device belongs to the 1N5333B through 1N5388B series of JEDEC registered silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a voltage range from 3.3V to 200V in a standardized 5-watt axial package. The e3 suffix indicates lead-free construction compliant with environmental directives.
Replacement Considerations
Equivalent parts within the same series include 1N5379B and 1N5381B for adjacent voltage ratings. Military screened equivalents are available with MQ, MX, or MV prefixes. Surface mount alternatives exist in the SMBJ and SMBG series.
