DCX55 Description

Short technical summary and product information.

The Diodes Incorporated DCX55 is an NPN epitaxial planar die construction transistor, ideally suited for automated assembly processes and medium power switching or amplification applications. It offers a collector-emitter voltage (VCEO) of 60V and a continuous collector current (IC) of 1A.

This device operates within a temperature range of -55°C to +150°C and has a power dissipation of 1W at 25°C. The transistor is housed in a SOT89-3L package, making it suitable for surface mount applications. Its terminals feature a matte tin finish over a copper leadframe, ensuring solderability per MIL-STD-202, Method 208.

The DCX55 is lead-free by design and RoHS compliant. Its complementary PNP type is available as the DCX52. Key electrical characteristics include a collector-emitter saturation voltage (VCE(SAT)) of 0.5V maximum at 500mA/50mA and a DC current gain (hFE) ranging from 63 to 250 depending on the operating conditions and specific part variant (DCX55 or DCX55-16). The transition frequency (fT) is typically 200MHz at 50mA/5V.
