The DTD543ZE3 is an NPN digital transistor with built-in bias resistors in an SOT-416 package, designed for inverter, interface, and driver circuits. It has a maximum collector current of 500 mA and a supply voltage rating of 12 V. The device features a built-in input resistor R1 of 4.7 kΩ and a resistor ratio R2/R1 of 10:1, enabling circuit simplification without external resistors. It operates with a maximum junction temperature of 150°C and a storage temperature range of -55°C to +150°C. The output saturation voltage is 300 mV maximum at 100 mA collector current. The package dimensions and tape reel specifications are defined for surface-mount mounting. It meets RoHS compliance and is rated for industrial use.
These are the standard products of "digital transistors" which ROHM invented and marketed first in the world.
