BC640 Frequently Asked Questions (FAQ)
-
The maximum operating temperature range for the BC640 is -55°C to 150°C.
-
Yes, the BC640 is suitable for switching applications due to its high current gain and low saturation voltage.
-
To ensure proper biasing, use a voltage divider network to set the base voltage, and ensure the collector-emitter voltage is within the recommended range (typically 5-10V).
-
The recommended storage temperature for the BC640 is -40°C to 100°C.
-
The BC640 is not suitable for high-frequency applications (>100 MHz) due to its limited transition frequency (ft) of 150 MHz.
