Overview
The Microsemi Corporation 1N5380A/TR8 is a silicon Zener diode with a nominal voltage of 120 V and a tolerance of ±10%. It operates in the T-18 axial leaded package, providing a maximum power dissipation of 5.0 watts at 25°C. The device features a test current of 10 mA, a maximum dynamic impedance of 170 ohms, and a maximum reverse current of 0.5 µA. It withstands a maximum surge current of 1150 A and has a thermal resistance of 25°C/W junction to lead.
Feature Summary
- Provides stable voltage regulation across broad operating current and temperature ranges
- Withstands high surge stresses and maintains minimal changes of voltage versus current
- Flexible axial-lead mounting terminals for versatile integration
- Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
Applications
- Voltage regulation over wide operating current and temperature ranges
- High surge stress applications requiring robust protection
- Circuits utilizing flexible axial-lead mounting terminals
Procurement Notes
Verify the specific suffix 'TR8' against official documentation to confirm tape and reel packaging details. Confirm RoHS compliance status as standard versions may differ from e3 variants. Ensure the component meets moisture classification Level 1 requirements without dry pack constraints. Validate that the ordering information matches the exact JEDEC registered part number specifications.
Selection Notes
Select this component when a 120 V Zener voltage with ±10% tolerance is required. Consider the 5-watt power rating and low thermal resistance design for adequate heat sinking. Evaluate the T-18 package dimensions for through-hole mounting compatibility. Verify that the specified surge current and dynamic impedance meet the circuit's transient and regulation needs.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for high maximum DC currents with adequate heat sinking.
Replacement Considerations
Equivalent surface mount options include SMBJ5380B or SMBG5380B. RoHS compliant replacements are available by adding the e3 suffix to the base part number.
