TIP146TU

Single Bipolar Transistors Overview

The TIP146TU is a PNP epitaxial silicon Darlington power transistor manufactured by onsemi. It features a monolithic construction with an integrated base-emitter shunt resistor. The device provides a minimum collector-emitter sustaining voltage of 80 Vdc and supports a continuous collector current of 10 A, with peak currents reaching 15 A. Total device dissipation is rated at 125 W at 25°C case temperature. It exhibits a minimum DC current gain of 1000 at 5 A collector current.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix TU corresponds to the TO-3P plastic package (Case 340D-02) as documented in the official datasheet. Confirm that the component meets the required electrical specifications for your application, particularly the 80 Vdc collector-emitter sustaining voltage and 10 A continuous current rating. Ensure thermal management aligns with the specified junction-to-case thermal resistance.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain PNP power transistor is required for driving loads up to 10 A. The integrated shunt resistor simplifies biasing networks compared to discrete Darlington pairs. Consider the 80 Vdc voltage rating for compatibility with system supply voltages. Evaluate thermal constraints based on the 125 W dissipation capability and the TO-3P package's thermal characteristics.

Single Bipolar Transistors Part Context

This part belongs to the TIP14x series of complementary Darlington transistors from onsemi. The series includes NPN counterparts such as the TIP141. These devices are designed for robust power handling in industrial and consumer electronics. The TIP146TU specifically serves as the PNP variant within this complementary pair structure.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include other manufacturers' TIP146T variants. Verify pinout compatibility with Case 340D-02 (TO-3P). Ensure replacement parts meet the 80 Vdc VCEO(sus) and 10 A IC ratings.
