Dual pre-biased transistor in a single SOT-363
The ROHM Semiconductor UMD3NTR packs one NPN and one PNP pre-biased transistor into a 6-pin UMT6 (SOT-363) package, each with integrated 10kΩ base and emitter-base resistors. This saves two discrete resistors per channel and shrinks the placement footprint compared to using separate transistors. With a 50V collector-emitter breakdown and 100mA continuous collector current, it handles typical low-side switching and level-shifting tasks in 3.3V or 5V logic systems. The 250MHz transition frequency keeps switching clean for signals up to a few megahertz.
