TechnologiesThe DTD143EG-AE3-R with Digital Transistors NPN – Pre-Biased 500mA 50V SOT-23 (SOT-23-3) RoHS manufactured by Unisonic Technologies is a three-terminal digital NPN transistor with pre-biased base designed for use in portable cell phones and other applications requiring high speed operation. It has a low collector-emitter saturation voltage (Vce(sat)) and a guaranteed collector current (Ic) capable of up to 500mA, a continuous collector current at 50V (VCEO). It is packaged in a SOT-23-3 RoHS compliant package and is capable of operating over an extremely wide temperature range of -55°C to +150°C. The maximum power dissipation (PD) is 300mW. The transistor has amplifier, switching, inverter, and logic applications and can be used as an amplifier, switch, current source, or as an active load for signal processing circuits. The fast switching speed and low power consumption make it an ideal choice in power-sensitive applications.
