DDTC143ECA-7-F Description

Short technical summary and product information.

The DDTC143ECA-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated. It features built-in biasing resistors with R1 and R2 both equal to 4.7 kΩ, simplifying circuit design by eliminating external resistor components.

 

This transistor has a maximum collector-emitter voltage of 50 V and a maximum collector current of 100 mA. It offers a DC current gain (hFE) minimum of 20 at Ic=10mA, Vce=5V, and a typical transition frequency of 250 MHz. The maximum saturation voltage is 300 mV at Ib=500µA, Ic=10mA.

 

The device is housed in a SOT23-3 package with matte tin plated leads and molded green plastic case. It is qualified to AEC-Q101 standards for automotive applications. Complementary PNP types (DDTA series) are available. It is fully RoHS3 compliant, lead-free, and halogen-free, with MSL Level 1 for unlimited floor life.
