Overview
The BC640BU is a PNP epitaxial silicon transistor designed for switching and amplifier applications. It features a collector-emitter voltage of -80 V, continuous collector current of -1 A, and peak collector current of -1.5 A. The device provides a DC current gain ranging from 25 to 160 depending on the operating point. It operates with a junction temperature up to 150 °C and dissipates 1 W of power in a TO-92 package.
Feature Summary
- PNP epitaxial silicon construction
- High collector current capability
- Complementary to BC639
Applications
- Switching circuits
- Amplifier applications
Procurement Notes
Verify the manufacturer origin, as Fairchild Semiconductor was acquired by onsemi. Confirm that the specific BC640BU variant matches the required electrical characteristics and package dimensions. Ensure compliance with RoHS standards if applicable to your project requirements.
Selection Notes
Select this component when a PNP transistor with high current handling and moderate voltage ratings is needed. It serves as a direct complement to the NPN BC639. Consider the thermal dissipation limits and ensure adequate heat sinking or airflow for sustained operation near maximum ratings.
Part Context
The BC640BU belongs to the BC640 family of PNP medium power transistors. This series includes various packaging options such as TA, TAR, TF, and TFR suffixes. The BU suffix specifically denotes the standard TO-92 plastic package configuration used for through-hole mounting.
Replacement Considerations
BC639 (NPN complement)
