DDTC124GCA-7-F Description

Short technical summary and product information.

The DDTC124GCA-7-F is an NPN pre-biased transistor from Diodes Incorporated, part of the DDTC R2-only series designed for surface mount applications. It integrates a 22kΩ biasing resistor (R2) within the device, reducing external component count and simplifying circuit design.

 

Key electrical ratings include a maximum collector-emitter voltage of 50V, a maximum collector current of 100mA, and a power dissipation of 200mW. The transistor offers a minimum DC current gain (hFE) of 56 at 5mA, 5V and a low VCE(sat) of 300mV at 10mA, 500µA. The device operates over a junction temperature range of -55°C to +150°C.

 

Housed in a standard SOT-23-3 surface mount package, the DDTC124GCA-7-F features a molded plastic case with UL 94V-0 flammability rating, matte tin lead finish, and MSL Level 1 moisture sensitivity. The device is lead-free, halogen and antimony free, and RoHS compliant.
