DDTA144ECAQ-13-F Description

Short technical summary and product information.

The DDTA144ECAQ-13-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, part of the DDTA series with integrated biasing resistors. It features epitaxial planar die construction and built-in 47kΩ resistors (R1=R2), simplifying circuit design by reducing external component count. The transistor offers a collector-emitter breakdown voltage of 50V, maximum collector current of 100mA, and power dissipation of 200mW. With a DC current gain (hFE) minimum of 68 at 5mA/5V and a transition frequency of 250MHz, it is suitable for switching and inverter applications. The device is housed in a SOT23-3 package (TO-236, SC-59 compatible) with surface mount mounting. It is fully RoHS3 compliant, lead-free, halogen-free, and rated as Moisture Sensitivity Level 1. The automotive grade (AEC-Q101 qualified) version is available, though this specific part number (DDTA144ECAQ-13-F) is marked as Not Recommended for New Design (NRND), with a recommended replacement of ADTA144ECAQ.
