Overview
The Microsemi Corporation 1N5380C/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 120 V and ±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 stable voltage regulation across a broad operating current and temperature range
- Withstands high surge stresses and exhibits minimal changes in voltage versus current
- Features flexible axial-lead mounting terminals for through-hole integration
Applications
- Voltage regulation circuits requiring tight tolerance stability
- High reliability applications utilizing military equivalent screening levels
- Power supply designs requiring robust surge stress handling
Procurement Notes
Verify the component status as this specific part number may be discontinued or subject to change. Confirm that the 'TR' suffix indicates tape and reel packaging per EIA-296 standards. Ensure compatibility with RoHS compliance requirements if applicable, noting that standard versions may not meet these specifications.
Selection Notes
Select this component when a precise 120 V reference with ±2% tolerance is required. The T-18 plastic encapsulation offers low thermal resistance for high DC currents with adequate heat sinking. Consider the C suffix designation specifically for tighter voltage accuracy compared to standard B or A suffix variants.
Part Context
This device belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zener diodes. The series provides voltage regulation from 3.3 to 200 volts. The 'C' suffix identifies the ±2% tolerance variant, while the 'TR' suffix denotes the tape and reel packaging option.
Replacement Considerations
Equivalent parts include other 120V 5W Zener diodes with ±2% tolerance in T-18 packages. Verify electrical parameters such as dynamic impedance and power derating curves before substitution.
