DIODES Incorporated Bipolar Transistors - Pre-Biased DCX142TH-7

The DCX142TH-7 is a complementary NPN/PNP pre-biased dual surface mount transistor in a SOT-563 package, measuring approximately 0.005 grams. It features built-in biasing resistors with R1 = 0.47 kΩ and R2 = open, enabling simplified circuit design. The device operates with a maximum supply voltage of ±50 V, collector current of ±100 mA, and power dissipation of 150 mW. It meets RoHS 2 and halogen-free "Green" standards, is rated for operation from -55°C to +150°C, and has a thermal resistance of 833 °C/W when mounted on an FR4 PCB. The NPN section provides a DC current gain (hFE) of 100 to 600 at IC = 1 mA and VCE = 5 V, while its gain-bandwidth product is 200 MHz. The PNP section mirrors these characteristics with symmetrical ratings.
