BC636

Single Bipolar Transistors Overview

The BC636 is a PNP epitaxial silicon transistor designed for switching and amplifier applications. It operates with a maximum collector current of 1 A and peak collector current of 1.5 A. The device supports a collector-emitter voltage of -45 V and emitter-base voltage of -5 V. Power dissipation reaches 1 W at 25°C ambient temperature, with a junction-to-ambient thermal resistance of 125 °C/W. DC current gain ranges from 25 to 250 depending on collector current conditions. The transition frequency is 100 MHz. Operating temperatures span from -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix (e.g., TA) against the required shipping configuration, as packaging varies between fan-fold units and other formats. Confirm that the component meets Pb-Free and Halogen-Free requirements if environmental compliance is mandatory for the assembly process. Ensure the TO-92-3 bent lead package aligns with the intended PCB footprint and mechanical constraints.

Single Bipolar Transistors Selection Notes

Select this component when a PNP medium-power transistor with 1 A continuous current capability is required. The device serves as the direct complement to the BC635 NPN transistor. Consider the TO-92-3 plastic package for through-hole mounting. Evaluate the 1 W power dissipation limit and thermal resistance characteristics against the expected operating environment and heat sinking provisions.

Single Bipolar Transistors Part Context

This part belongs to the BC63x series of PNP epitaxial silicon transistors manufactured by onsemi. It is functionally paired with the BC635 NPN transistor to form complementary sets. The device utilizes a TO-92-3 case style (Case 135AR) with kinked leads for standard through-hole integration. It is widely used in general-purpose electronic designs requiring moderate power handling.
