Central Semiconductor Corp. Darlington Transistors CZTA14 BK

The CZTA14 is an NPN silicon Darlington transistor in an SOT-223 package, designed for applications requiring high current gain. It features a collector-base voltage rating of 30 V, a collector-emitter voltage rating of 30 V, and a continuous collector current of 500 mA. Power dissipation is rated at 2.0 W, with a thermal resistance of 62.5 °C/W. The transistor exhibits a minimum current gain (hFE) of 10,000 at IC=10 mA and 20,000 at IC=100 mA, with a collector-emitter saturation voltage of 1.5 V at IC=100 mA and IB=0.1 mA. The device operates within a junction temperature range of -65 to +150 °C. The SOT-223 package has dimensions of 6.30 to 6.85 mm in length, 2.90 to 3.10 mm in width, and 3.30 to 3.70 mm in lead spacing. The marking on the device includes the full part number.
