The MMBT3904K is a versatile NPN epitaxial silicon transistor manufactured by On Semiconductor. It is designed for general-purpose applications requiring reliable switching and amplification.
Key electrical characteristics include a collector-emitter voltage (VCEO) of 40V and a continuous collector current (IC) of 200mA. The transistor offers a typical DC current gain (hFE) of 100 at 10mA and 1V, with a gain-bandwidth product (fT) of 300MHz at 10mA and 20V. Its low saturation voltages, VCE(sat) of 0.3V and VBE(sat) of 0.85V at specified currents, ensure efficient operation.
Packaged in a compact SOT-23-3 surface-mount case, the MMBT3904K is suitable for modern electronic designs. It operates across a wide temperature range of -55°C to 150°C. The transistor's specifications make it a suitable choice for various applications in consumer electronics, portable devices, and switching circuits.
This transistor is also noted for its fast switching times, with a turn-on time (tON) of 70ns and a turn-off time (tOFF) of 250ns. Its output capacitance (Cob) is a maximum of 4pF at 1MHz, contributing to its high-frequency performance.
