DDTA143ECA-7-F Description

Short technical summary and product information.

The DDTA143ECA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, part of the DDTA series with built-in biasing resistors (R1=R2=4.7kΩ). It features an epitaxial planar die construction and is designed for use in switching and inverter circuits where space and component count reduction are critical.

 

Electrical characteristics include a maximum collector-emitter breakdown voltage of 50V, maximum collector current of 100mA, and power dissipation of 200mW. The DC current gain (hFE) is a minimum of 20 at Ic=10mA and Vce=5V, and the transition frequency is 250 MHz. The saturation voltage is 300mV maximum at Ib=500µA and Ic=10mA.

 

The transistor is housed in a SOT-23-3 package with matte tin plated leads and a green molding compound. It is surface mountable and weighs approximately 0.008 grams. The device is fully RoHS3 compliant, halogen and antimony free, and qualified to AEC-Q101 standards for high reliability applications. Moisture sensitivity is Level 1 per J-STD-020.
