DDTC143ZCA-7-F Description

Short technical summary and product information.

The DDTC143ZCA-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It integrates two biasing resistors (R1=4.7kΩ and R2=47kΩ) into a single SOT-23-3 package, reducing external component count and simplifying PCB layout.

 

Key electrical specifications include a collector-emitter voltage (Vceo) of 50V, a collector current (Ic) of 100mA, and a power dissipation (Pd) of 200mW. The device offers a minimum DC current gain (hFE) of 80 at Ic=10mA, Vce=5V, and a transition frequency (ft) of 250MHz. The maximum collector-emitter saturation voltage (Vce(sat)) is 300mV at Ib=250µA, Ic=5mA.

 

The transistor is housed in a surface-mount SOT-23-3 package with gull-wing leads and matte tin termination finish. It is qualified to AEC-Q101 standards for high reliability and is RoHS3 compliant, lead-free, and halogen-free. The device is supplied on 7-inch reels with 8mm tape width, containing 3000 units per reel.
