DDTC144ECA-7-F Description

Short technical summary and product information.

The DDTC144ECA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, designed for switching and amplifier applications where space and component count reduction are critical. It integrates two 47kΩ bias resistors (R1 and R2) in a single SOT-23-3 package, eliminating the need for external biasing components.

 

This device is rated for a maximum collector-emitter voltage of 50V and a maximum collector current of 100mA, with a power dissipation of 200mW. It offers a typical transition frequency of 250MHz and a minimum DC current gain (hFE) of 68 at 5mA collector current and 5V collector-emitter voltage. The collector-emitter saturation voltage is typically 300mV at 500µA base current and 10mA collector current.

 

The DDTC144ECA-7-F is housed in a surface-mount SOT-23-3 package with matte tin plated terminals, suitable for automated assembly. It is qualified to AEC-Q101 standards for high reliability and is fully RoHS compliant, halogen and antimony free, with a UL 94V-0 flammability rating.
