DCX143EU-7-F

The DCX143EU-7-F is a complementary NPN/PNP pre-biased transistor array from Diodes Incorporated, housed in a compact SOT-363 surface-mount package. It integrates two matched transistors with built-in bias resistors (R1 = R2 = 4.7 kΩ) to simplify circuit design and reduce component count. The device is rated for a collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation of 200 mW.

Key electrical characteristics include a minimum DC current gain (hFE) of 50 for the NPN transistor and 40 for the PNP transistor at Ic=10 mA, Vce=5 V. The typical transition frequency is 250 MHz, making it suitable for switching and amplification applications up to moderate frequencies. The maximum collector-emitter saturation voltage is 300 mV at Ib=500 µA, Ic=10 mA.

The DCX143EU-7-F is supplied in a SOT-363 package with gull-wing leads and matte tin plating. It is fully RoHS compliant, lead-free, halogen-free, and meets MSL Level 1 moisture sensitivity. The device is also AEC-Q101 qualified for automotive applications as per the datasheet. Typical applications include signal switching, driver stages, and interface circuits where space-saving and integrated bias resistors are advantageous.
