DDTC144WCA-7-F Description

Short technical summary and product information.

The DDTC144WCA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated. It integrates two biasing resistors (R1=47kΩ and R2=22kΩ) to simplify circuit design and reduce component count. The device is rated for a maximum collector-emitter voltage of 50V and a maximum collector current of 100mA, with a power dissipation of 200mW.

 

This transistor features a minimum DC current gain (hFE) of 56 at 5mA and 5V, and a maximum Vce saturation voltage of 300mV at 500µA base current and 10mA collector current. It offers a transition frequency (fT) of 250 MHz, making it suitable for switching and amplifier applications.

 

The DDTC144WCA-7-F is housed in a SOT-23-3 package with flat leads (SOT-23F) and is qualified to AEC-Q101 standards for automotive reliability. It is RoHS3 compliant, lead-free, and halogen-free, with a moisture sensitivity level of 1 per J-STD-020.
