UMD6NFHATR

ROHM Semicon · Digital Transistors · SOT-363

UMD6NFHATR from ROHM Semicon, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DTr1_E passive Emitter of DTr1 (NPN digital transistor). Typically tied to system ground when used as a low-side driver. Part of the DTC143T-equivalent element (V_CEO = 50 V, I_C = 100 mA, built-in base resistor R1 = 4.7 kΩ).
2 DTr1_B input Base input of DTr1 (NPN). Drives the internal 4.7 kΩ series resistor into the NPN base; V_EBO = 5 V max. Logic-level input for the NPN pre-biased transistor.
3 DTr2_C output Collector of DTr2 (PNP digital transistor). Open-collector output rated V_CEO = -50 V, I_C = -100 mA. Typically connected to the load being switched (high-side driver configuration).
4 DTr2_E passive Emitter of DTr2 (PNP digital transistor). Typically tied to the positive supply rail when used as a high-side driver. Part of the DTA143T-equivalent element (V_CEO = -50 V, I_C = -100 mA, R1 = 4.7 kΩ).
5 DTr2_B input Base input of DTr2 (PNP). Drives the internal 4.7 kΩ series resistor into the PNP base; V_EBO = -5 V max. Logic-level input for the PNP pre-biased transistor (active-low relative to emitter).
6 DTr1_C output Collector of DTr1 (NPN digital transistor). Open-collector output rated V_CEO = 50 V, I_C = 100 mA. Typically connected to the load being switched (low-side driver configuration).
