Overview
The Microsemi Corporation 1N5380A/TR12 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333B-1N5388B series, housed in an axial-lead T-18 package. It provides voltage regulation at a nominal Zener voltage of 120V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 170 Ohms at a test current of 10mA. It includes a TR suffix for tape and reel packaging.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Features flexible axial-lead mounting terminals suitable for through-hole applications
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack
Applications
- Voltage regulation in power supply circuits
- Protection of sensitive electronic components from transient overvoltages
- Reference voltage generation in measurement equipment
Procurement Notes
Verify the specific suffix 'A' confirms the ±10% tolerance requirement for your design. Confirm that the 'TR' suffix matches your automated assembly equipment's tape and reel specifications. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits during operation.
Selection Notes
Select this component when a 120V regulation point is required with moderate tolerance. Consider the 5W power dissipation rating and the T-18 package size for board space constraints. Evaluate the need for the tape and reel format against manual or wave soldering processes if alternative packaging is preferred.
Part Context
This part belongs to the 1N5333B through 1N5388B series of 5.0-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3V to 200V. These plastic encapsulated devices are designed for high reliability and offer various military equivalent screening levels upon request.
Replacement Considerations
Equivalent parts include other manufacturers' 1N5380A variants in the T-18 package. Surface mount equivalents such as SMBJ5380A or SMBG5380A are available from Microsemi for designs requiring different form factors.
