The FMB3946 is a complementary NPN/PNP transistor array from On Semiconductor, designed for general-purpose amplifier and switch applications. It integrates one NPN and one PNP transistor in a single surface mount package, simplifying board layout and reducing component count.
Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 40 V, a maximum collector current (IC) of 200 mA, and a power dissipation of 700 mW at 25°C ambient. The device offers a DC current gain (hFE) ranging from 100 to 300 at 10 mA, with a typical transition frequency (fT) of 200 MHz, making it suitable for amplification up to 100 MHz. The maximum VCE(sat) is 250 mV at 10 mA base current.
The FMB3946 is housed in a TSOT-23-6 thin package (also known as SuperSOT-6) and is surface mountable. It is rated for an operating junction temperature range of -55°C to 150°C. The device is supplied in tape and reel packaging with 3000 units per reel. Thermal resistance from junction to ambient (RθJA) is 180°C/W for a standard FR-4 PCB.

The maximum collector-emitter voltage (VCEO) is 40 V, and the maximum collector-base voltage (VCBO) is also 40 V. The emitter-base voltage (VEBO) is 5 V.
The FMB3946 is available in a TSOT-23-6 thin package (also called SuperSOT-6) for surface mount assembly.
The junction operating temperature range is -55°C to 150°C.
The FMB3946 is listed as RoHS3 compliant, but this status is unverified and should be treated as low confidence.
At IC=10mA and VCE=1V, the hFE ranges from 100 to 300. Minimum values are specified at other test conditions: 40 at 100µA, 70 at 1mA, 60 at 50mA, and 30 at 100mA.
The maximum continuous collector current (IC) is 200 mA.
The typical transition frequency (fT) is 200 MHz at IC=10mA.
