BCX70J is an NPN silicon bipolar transistor for AF input stages and driver applications, housed in a SOT23 package. It has a collector-emitter voltage rating of 45 V, a collector current rating of 100 mA, and a total power dissipation of 330 mW at a case temperature below 71 °C. The transistor meets AEC-Q101 qualification and is RoHS compliant. Its DC current gain (hFE) ranges from 300 to 460 at IC = 2 mA and VCE = 5 V, with a transition frequency of 250 MHz and low noise figure up to 2 dB at 200 µA collector current. Collector-emitter saturation voltage is specified as 0.55 V max at IC = 50 mA and IB = 1.25 mA. Complementary PNP types are BCW61 and BCX71.
