TIP42CTU-T

Single Bipolar Transistors Overview

The Fairchild Semiconductor TIP42CTU-T is a PNP epitaxial silicon power transistor housed in a TO-220 package. It serves as the complementary device to the TIP41 series, designed for medium power linear and switching applications. Key electrical ratings include a collector-emitter voltage of -100 V, a continuous collector current of -6 A, and a maximum power dissipation of 65 W at 25°C case temperature. The device features a DC current gain ranging from 15 to 75 under specified conditions.

Single Bipolar Transistors Feature Summary

• Complementary pairing with the TIP41 NPN series
• Epitaxial silicon construction for robust performance
• Designed for medium power linear and switching operations

Single Bipolar Transistors Applications

• Medium power linear amplifier circuits
• General purpose switching applications
• Audio output stages requiring complementary pairs

Single Bipolar Transistors Procurement Notes

Verify that the ordering suffix TU corresponds to rail packing rather than bulk or tape-and-reel formats. Confirm the specific voltage grade (TIP42C indicates -100V rating) matches the circuit requirements. Ensure the manufacturer designation aligns with ON Semiconductor legacy documentation. Cross-reference the publication number TIP42C/D for accurate technical specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP counterpart to the TIP41 series is required for balanced push-pull configurations. Consider the -100V collector-emitter breakdown voltage for higher voltage applications compared to the standard TIP42. Evaluate thermal management needs given the 65W dissipation rating in the TO-220 package. Verify compatibility with existing PCB footprints designed for TO-220 mounting.

Single Bipolar Transistors Part Context

This part belongs to the widely used TIP41/TIP42 family of medium power transistors. The TIP42C variant specifically offers enhanced voltage ratings compared to the base TIP42 model. Manufactured originally by Fairchild Semiconductor and now maintained by ON Semiconductor, these devices are industry standards for general-purpose power amplification and switching tasks.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the generic TIP42C from other manufacturers. Complementary replacements for the NPN side remain TIP41C variants. Verify pinout compatibility for TO-220 packages before substitution.
