DDC123JU-7

Overview

The DDC123JU-7-F is a dual NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It integrates two NPN transistors with built-in biasing resistors (R1 = 2.2 kΩ, R2 = 47 kΩ) in an SOT-363 package. The device features a collector-emitter breakdown voltage of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. The component is lead-free, RoHS compliant, and suitable for automated assembly.
