TIP105

Single Bipolar Transistors Overview

The TIP105 is a silicon Epitaxial-Base PNP power Darlington transistor manufactured by STMicroelectronics. It is housed in a TO-220 plastic package designed for through-hole mounting. The device supports a maximum collector current of 8 A and a collector-emitter breakdown voltage of 60 V. Key electrical specifications include a minimum DC current gain (hFE) of 2000 at 3 A and 4 V, a maximum collector cutoff current of 50 µA, and a maximum saturation voltage of 2.5 V at 80 mA base current and 8 A collector current. The component has a maximum power dissipation of 2 W and operates within a junction temperature range up to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the obsolete status and discontinuance notification date before procurement planning. Confirm availability through authorized distributors as standard supply may be limited. Ensure compliance with RoHS3 and REACH regulations if required for the specific application environment. Check for alternative sourcing channels due to end-of-life status.

Single Bipolar Transistors Selection Notes

Select this component for high-current PNP switching or linear regulation tasks requiring high gain. Consider the complementary NPN type TIP102 for matched pairs. Evaluate thermal management needs given the 2 W power dissipation limit in the TO-220 package. Verify that the 60 V voltage rating meets the circuit's peak operating conditions.

Single Bipolar Transistors Part Context

The TIP105 belongs to STMicroelectronics' portfolio of low-voltage PNP power Darlington transistors. It is part of a series offering voltage ranges up to 400 V with both NPN and PNP polarities. This specific model represents a legacy component within the broader discrete semiconductor lineup, historically used in general-purpose power control designs.
