Overview
The BCX22 PBFREE is an NPN bipolar junction transistor manufactured by Central Semiconductor Corp. It is designed for amplification and switching applications with a collector-base voltage of 125V and a collector-emitter voltage of 125V. The device features a bulk packaging format and carries the PBFREE suffix to indicate lead-free construction compliant with RoHS standards.
Feature Summary
- NPN polarity configuration suitable for general-purpose amplification and switching tasks
- High voltage capability with 125V ratings for both collector-base and collector-emitter terminals
- Lead-free solder finish ensuring compliance with environmental directives
Applications
- General purpose signal amplification circuits
- Electronic switching applications requiring moderate voltage handling
- Discrete component designs in consumer or industrial electronics
Procurement Notes
Verify current availability status as the product may be subject to discontinuation or limited supply constraints. Confirm that the specific order requires the PBFREE variant to ensure compliance with lead-free manufacturing requirements. Check official datasheets for exact electrical limits before integration into final designs.
Selection Notes
Select this component when an NPN transistor with 125V breakdown voltage is required for discrete circuit designs. Ensure the application does not exceed the specified collector currents or power dissipation limits defined in the manufacturer's documentation. Consider package compatibility during PCB layout planning.
Part Context
Central Semiconductor specializes in discrete semiconductors, including legacy and standard devices. The BCX22 represents their offering in the NPN BJT category, targeting markets needing reliable amplification components. The company supports various packaging options and complies with international environmental standards for electronic materials.
Replacement Considerations
Consult Central Semiconductor’s cross-reference tools for equivalent parts if this model is unavailable. Verify pinout compatibility and electrical specifications match before substituting with other manufacturers' NPN transistors having similar voltage ratings.
