DMMT3904W-7

The DMMT3904W-7 is a dual NPN matched pair transistor from Diodes Incorporated, designed for applications requiring tight electrical matching between two transistors. It is built using adjacent die from the same wafer to achieve intrinsic matching, with a current gain matching of 2% and base-emitter voltage matching of 2mV. Key electrical specifications include a maximum collector-emitter voltage of 40V, continuous collector current of 200mA, DC current gain (hFE) of at least 100 at 10mA, and a transition frequency of 300MHz.

This matched pair is ideal for precision analog circuits such as current mirrors, differential amplifiers, and comparators where consistent transistor characteristics are critical. The parts are fully internally isolated, allowing independent operation of each transistor within the small SOT363 package.

The DMMT3904W-7 is surface mount in a 6-pin SOT363 package (also known as SC-88 or 6-TSSOP). The package is molded from green molding compound, is halogen and antimony free, and has matte tin terminals. It is RoHS3 compliant and lead-free. Moisture sensitivity is Level 1 per J-STD-020, and the operating temperature range is -65°C to 150°C. The device is also available in an automotive-compliant variant (DMMT3904WQ).
