TIP42CTU

Single Bipolar Transistors Overview

The TIP42CTU is a PNP epitaxial silicon power transistor manufactured by onsemi, belonging to the TIP42C series. It features a TO-220AB through-hole package with three pins. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 100 V and a continuous collector current (IC) of 6 A. The device supports a total power dissipation of 65 W at 25°C case temperature, with a junction-to-case thermal resistance of 1.92°C/W. The saturation voltage (VCE(sat)) is specified at 1.5 V maximum when IC equals 6 A.

Single Bipolar Transistors Feature Summary

• Utilizes base island technology to enhance switching speed and improve hFE linearity

Single Bipolar Transistors Applications

• General-purpose audio amplifiers
• Power linear regulation circuits
• High-speed switching applications

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'TU' against official onsemi documentation, as standard listings often use 'TIP42C'. Confirm RoHS compliance status and lead times directly with authorized distributors, noting that availability may vary. Ensure the ordering part number matches the exact package and marking requirements for your design.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a robust PNP power transistor with 100 V blocking capability and 6 A current handling. Consider the thermal management requirements given the 65 W dissipation rating in a TO-220 package. Verify compatibility with complementary NPN devices like the TIP41C for balanced circuit performance.

Single Bipolar Transistors Part Context

The TIP42CTU is part of the broader TIP42 family of complementary silicon power transistors produced by onsemi. This family includes variants with different voltage ratings such as TIP42G (40 V), TIP42AG (60 V), and TIP42BG (80 V). The TIP42C variant specifically provides the highest voltage rating within the standard series, making it suitable for higher voltage power supply and audio applications.

Single Bipolar Transistors Replacement Considerations

Public confirmed substitutes include the TIP42CG from onsemi and the TIP42C from STMicroelectronics. These parts share identical electrical characteristics and pinout configurations, allowing for direct replacement in most designs.
