Overview
The Central Semiconductor Corp 2N5303 PBFREE is a silicon NPN power transistor housed in a TO-3 flange mount package. It supports a maximum collector current of 20 A and dissipates up to 200 W of power. The device features an 80 V collector-emitter breakdown voltage (BVCEO) and an 80 V collector-base breakdown voltage (BVCBO). Minimum DC current gain (hFE) is specified at 15 when tested at a collector current of 10 A. The saturation voltage (VCE(SAT)) is rated at a maximum of 2.0 V under the same test conditions.
Feature Summary
- High-power capability with 200 W dissipation rating for robust thermal management
- Flange-mount construction facilitating direct heatsink attachment
- Silicon planar epitaxial structure ensuring stable switching performance
Applications
- Industrial motor control systems
- High-current linear power supply regulation
- Audio amplifier output stages
Procurement Notes
Verify component authenticity by matching the manufacturer part number against official datasheets. Confirm that the ordering suffix indicates lead-free plating status as required by project specifications. Ensure the physical package matches the TO-3 mechanical drawing dimensions before integration into the assembly process.
Selection Notes
Select this component for designs requiring high collector current handling within a metal can package. Evaluate thermal resistance requirements carefully due to the 200 W power dissipation rating. Compare the 80 V breakdown voltage against circuit operating limits to ensure adequate safety margins during transient events.
Part Context
This device belongs to the Central Semiconductor power transistor portfolio, designed for heavy-duty applications. It utilizes a standard TO-3 case style which provides electrical isolation between the collector and the mounting hardware. The product line emphasizes reliability in industrial environments through rigorous material composition controls.
Replacement Considerations
Central Semiconductor has classified the 2N5303 as End of Life (EOL) per notice PDN01250. No suggested replacement part numbers are provided in the official discontinuation documentation.
