DDC124EU-7-F

The DDC124EU-7-F is a dual NPN pre-biased small signal transistor from Diodes Incorporated, designed for low-power switching and driver applications. It integrates two NPN transistors with built-in bias resistors (R1=R2=22kΩ) in a single SOT-363 package, reducing external component count and simplifying PCB layout. Key electrical characteristics include a collector-emitter voltage rating of 50V, a collector current of 100mA, a power dissipation of 200mW, and a transition frequency of 250MHz. The minimum DC current gain (hFE) is 56 at 5mA, 5V, and the maximum Vce saturation voltage is 300mV at 10mA, 500µA.

This device is housed in a compact surface-mount SOT-363 package with gull-wing terminals and matte tin plated leads. It is supplied in tape and reel packaging with 3000 pieces per reel. The DDC124EU-7-F is RoHS3 compliant, lead-free, and halogen-free, with a moisture sensitivity level of 1 per J-STD-020. The molding compound is rated UL94 V-0 for flammability.

Pre-biased transistors are ideal for applications where space and component count are critical, such as portable electronics, relay drivers, LED drivers, and signal amplification stages. The built-in resistors ensure consistent biasing and reduce tolerance variations.
