Frequently Asked Questions
What are the key features of the BC857BS double transistor?
It offers low collector capacitance, low collector-emitter saturation voltage, closely matched current gain, and no mutual interference between transistors.
Is there a complement for the BC857BS PNP double transistor?
Yes, the NPN complement is BC847BS.
What are the absolute maximum ratings for I_C and P_D?
The typical limiting value for I_C is -100 mA, and for P_D (per device) it is -300 mW total at ambient T.<0xC2><0xA0>
How does mounting affect the thermal resistance (Rth)?
The Rth of 416 K/W is specified when the device is mounted on an FR4 printed-circuit board.
