DTD743XE / DTD743XM is a low voltage integrated switch transistor launched by ROHM. The product has the characteristics of low Vce (sat), built-in bias resistor, etc., and is suitable for switch power supply, driver circuit, interface circuit and other scenarios.
The DTD743XE and DTD743XM are low‑VCE (sat) NPN digital transistors with built‑in thin‑film bias resistors, allowing inverter circuits without external resistors. Their structure provides isolation for negative biasing and minimizes parasitic effects, simplifying circuit design.
These devices are intended for inverter, interface and driver applications in audio‑visual, office‑automation, communication and other electronic equipment. Key ratings include a 30 V supply voltage, 200 mA maximum collector current, and operation over a wide temperature range.
