DDTC122TU-7-F Description

Short technical summary and product information.

The DDTC122TU-7-F from Diodes Incorporated is an NPN pre-biased surface mount transistor designed for low-power switching and driver applications. It integrates a 220Ω base resistor (R1) and an open base-emitter resistor (R2), reducing external component count and simplifying PCB design. The transistor features a maximum collector-emitter voltage (VCEO) of 50V, a continuous collector current (IC) of 100mA, and a power dissipation (Pd) of 200mW.

 

Electrical performance includes a minimum DC current gain (hFE) of 100 at 1mA and 5V VCE, a typical transition frequency (ft) of 200MHz, and a low VCE saturation voltage of 300mV maximum at 250µA base current and 5mA collector current. This makes it suitable for signal amplification and switching in portable and space-constrained electronics.

 

The device is housed in a SOT-323 (SC-70) surface mount package with dimensions as per the datasheet. It is molded in green compound with UL 94V-0 flammability rating, has solderable terminals per MIL-STD-202 Method 208, and weighs approximately 0.006 grams. The part is fully RoHS compliant, lead-free, and halogen-free. Note that Diodes Incorporated has marked this part as obsolete; please contact the manufacturer for availability and alternatives.
