The DTD143EK is an NPN digital transistor from ROHM Semiconductor USA, LLC, featuring built-in biasing resistors (R1 = R2 = 4.7kOc) that facilitate easy circuit design by eliminating the need for external input resistors. This transistor is suitable for applications such as switching circuits, inverter circuits, interface circuits, and driver circuits. It has a maximum supply voltage of 50V, a collector current rating of 500mA, and a power dissipation capability of 200mW. The device operates within a junction temperature range of -55¬8C to +150¬8C and is compliant with RoHS standards. The DTD143EK is packaged in a SOT-346 (SC-59) format, making it suitable for surface mount technology. Its built-in resistors are designed to provide complete isolation, allowing for negative biasing of the input and minimizing parasitic effects.
These are the standard products of "digital transistors" which ROHM invented and marketed first in the world.
