TIP42C-S

Single Bipolar Transistors Overview

The TIP42C-S is a PNP power transistor manufactured by Bourns Inc., housed in a TO-220 plastic package. It serves as the complementary device to the NPN TIP41C within the same product family. The component utilizes base island technology, which supports high switching speed and enhanced series performance. Key electrical characteristics include a collector-emitter voltage rating of 100V and a continuous collector current capacity of 6A. These specifications define its operational limits for power handling and voltage blocking in electronic circuits.

Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer origin when sourcing this part number, as multiple entities produce equivalent TIP42C variants. Confirm that the TO-220 package dimensions match your PCB footprint requirements. Ensure the 100V and 6A ratings align with your system's maximum load conditions. Check for RoHS compliance status if required by your manufacturing standards. Validate the supplier's authenticity to avoid counterfeit components.

Single Bipolar Transistors Selection Notes

Select this component when a PNP counterpart is needed for an existing NPN-based design utilizing the TIP41C. Consider the TO-220 package size constraints for thermal management and board space. Evaluate the 100V breakdown voltage against peak transient voltages in the circuit. Assess the 6A current limit against continuous load requirements. Verify compatibility with the intended driver circuitry for proper biasing.

Single Bipolar Transistors Part Context

This transistor belongs to a widely recognized family of complementary power bipolar junction transistors. The series includes both NPN (TIP41C) and PNP (TIP42C) variants designed for mutual matching. This grouping facilitates the creation of balanced amplifier stages and power supply circuits. The technology represents a standard solution for medium-power applications requiring reliable switching and linear operation.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include other manufacturers' TIP42C or TIP42 parts. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement meets the 100V and 6A specifications. Cross-reference datasheets for hFE grouping requirements if linearity is critical.
