Overview
The Microsemi 1N5381C/TR8 is a silicon axial-lead Zener diode with a nominal voltage of 130V and ±2% tolerance. It operates within the 1N5333B–1N5388B series, rated for 5W power dissipation at 25°C lead temperature. The device features a T-18 plastic package and includes a tape-and-reel suffix (TR8) for automated assembly.
Feature Summary
- Provides precise voltage regulation with tight manufacturing tolerances
- Capable of handling high surge currents when adequately heat sunk
- Features low thermal resistance design for efficient power dissipation
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive electronic components
- Reference voltage sources in measurement equipment
Procurement Notes
Verify the specific suffix configuration to ensure compatibility with required tolerance levels and packaging formats. Confirm that the TR8 designation aligns with automated placement equipment specifications. Cross-reference the manufacturer's current datasheet to validate electrical parameters against original design requirements before finalizing procurement orders.
Selection Notes
Select this component when a stable 130V reference with high precision is required. The 5W rating supports robust operation under steady-state conditions. Ensure adequate thermal management is implemented to maintain junction temperatures within safe operating limits during continuous use.
Part Context
This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The 'C' suffix indicates a ±2% voltage tolerance, while 'TR8' denotes the tape and reel packaging format. These devices are designed for general-purpose voltage regulation applications requiring reliable performance over a wide temperature range.
Replacement Considerations
Equivalent parts include other 130V Zener diodes with similar power ratings and tolerance levels. Verify mechanical dimensions and pinout compatibility before substitution. Consult manufacturer cross-reference guides for direct replacements within the same product family.
