DDTD123YC-7-F Description

Short technical summary and product information.

The DDTD123YC-7-F is an NPN pre-biased transistor manufactured by Diodes Incorporated. It integrates built-in biasing resistors (R1 = 2.2 kΩ, R2 = 10 kΩ), simplifying circuit design by reducing external component count. The device is rated for a collector current of 500 mA and a collector-emitter voltage of 50 V, with a power dissipation of 200 mW.

This transistor uses epitaxial planar die construction and is housed in a SOT-23-3 surface-mount package. The package is molded with a green molding compound, is totally lead-free, and fully RoHS compliant. It also meets UL flammability classification rating 94V-0 and has moisture sensitivity level 1 per J-STD-020.

The DDTD123YC-7-F is suitable for general-purpose switching and amplification applications where space and component count are critical. Its pre-biased configuration makes it ideal for use in digital logic circuits, driver stages, and interface circuits. The device is supplied in tape and reel packaging with 3,000 units per reel, facilitating automated assembly.
