Central Semiconductor Corp. Darlington Transistors CZTA28 TR

The CZTA28 is a silicon NPN Darlington transistor in an SOT-223 surface-mount package, designed for applications requiring high current gain. It has a maximum collector-emitter voltage of 80 V, a continuous collector current of 500 mA, and a power dissipation of 2.0 W. The operating and storage junction temperature range is -65 to +150 °C, with a thermal resistance of 62.5 °C/W. The device exhibits a minimum hFE of 10,000 at IC = 10 mA and IC = 100 mA, and a saturation voltage of 1.5 V at IC = 100 mA and IB = 100 µA. The SOT-223 package dimensions are specified with a body length of 6.30 to 6.85 mm and a width of 3.30 to 3.70 mm. The marking includes the full part number.
