Overview
The DDTA144GKA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, utilizing epitaxial planar die construction. It features a built-in bleeder resistor (R2) with a nominal value of 47 kΩ housed in an SC-59 package. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA at 25°C. The device supports a power dissipation of 200 mW and operates within a temperature range of -55°C to +150°C. It exhibits a DC current transfer ratio (hFE) minimum of 68 and a gain-bandwidth product of 250 MHz.
