Overview
The Microsemi Corporation 1N5380C/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 120 V and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C and features an axial-lead T-18 package. The device has a maximum dynamic impedance of 170 ohms, a reverse current of 0.5 µA at 86.4 V, and a maximum regulator current of 39.5 mA.
Feature Summary
- Provides precise voltage regulation with tight ±2% tolerance
- Operates reliably across a wide temperature range from -65°C to +150°C
- Withstands high surge stresses and maintains minimal voltage changes versus current
- Features flexible axial-lead mounting terminals for through-hole applications
Applications
- Voltage regulation in broad operating current ranges
- High-reliability circuit protection against transient voltages
- Power supply stabilization requiring low thermal resistance design
Procurement Notes
Verify the component status as this part may be discontinued or subject to product change notifications. Confirm that the TR suffix indicates tape and reel packaging per EIA-296 standards. Ensure compatibility with MIL-PRF-19500 screening levels if military-grade reliability is required for the specific application environment.
Selection Notes
Select this component when a 120 V reference with high precision is needed. The C suffix ensures a tighter tolerance than standard B or A variants. Consider the T-18 package size for adequate heat sinking to support the 5-watt power dissipation rating under steady-state conditions.
Part Context
This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0-watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts. The plastic encapsulated construction provides Level 1 moisture classification without requiring dry pack storage.
Replacement Considerations
Equivalent parts include other 120 V 5 W Zener diodes in T-18 packages. Verify tolerance and thermal characteristics match the original design requirements before substitution.
