DDTD142JC-7-F

The DDTD142JC-7-F is an NPN pre-biased bipolar junction transistor from Diodes Incorporated. It integrates two biasing resistors (R1 = 0.47 kΩ, R2 = 10 kΩ) in a SOT-23-3 surface-mount package, eliminating the need for external resistor components in switching and amplifier circuits.

This device is rated for a collector-emitter voltage of 50 V and a continuous collector current of 500 mA, with a power dissipation of 250 mW. It offers a minimum DC current gain (hFE) of 56 at Ic = 50 mA and Vce = 5 V, and a maximum collector-emitter saturation voltage of 300 mV at Ib = 2.5 mA and Ic = 50 mA. The transition frequency is 200 MHz.

The built-in resistors simplify circuit design by reducing component count and assembly cost. The transistor is suitable for a wide range of switching and signal-conditioning applications, including logic level shifting, relay drivers, and LED drivers. A complementary PNP type (DDTB series) is also available for push-pull configurations.

The DDTD142JC-7-F is supplied in a SOT-23-3 package with gull-wing leads, finished with matte tin for excellent solderability. It is RoHS3 compliant, lead-free, and halogen-free, with a moisture sensitivity level of 1 per J-STD-020. The device is available in tape-and-reel packaging with 3,000 pieces per reel.
