DDTC123JUA-7-F Description

Short technical summary and product information.

The DDTC123JUA-7-F from Diodes Incorporated is an NPN pre-biased transistor featuring integrated bias resistors R1=2.2kΩ and R2=47kΩ, reducing external component count and simplifying PCB layout.

Key electrical characteristics include a collector-emitter voltage (Vceo) of 50V, continuous collector current of 100mA, and power dissipation of 200mW. Minimum DC current gain (hFE) is 80 at Ic=10mA, Vce=5V, with a transition frequency of 250MHz. Vce saturation is 300mV maximum at Ib=250µA, Ic=5mA.

Housed in a SOT323 surface mount package, the device is lead-free, RoHS3 compliant, and halogen/antimony free. The package material is green molding compound with UL 94V-0 flammability rating, and moisture sensitivity is Level 1 per J-STD-020.

Ideal for low-power switching, load driving, and signal amplification in space-constrained designs.
