DTB543XE / DTB543XM is a low VCE (sat) digital transistor with built-in resistors from Toshiba, suitable for inverter, interface and driver applications.
The DTB543XE and DTB543XM are low VCE (sat) digital transistors with built‑in thin‑film bias resistors, making them suitable for inverter, interface, and driver circuits. Their integrated resistors simplify circuit design by eliminating the need for external input resistors and reducing parasitic effects.
The devices are supplied in an SOT‑416 (SC‑75A) package, with external dimensions of 1.6 mm × 0.7 mm × 0.15 mm. Electrical characteristics include a maximum collector current of 500 mA, a supply voltage range of –12 V to +7 V, and a transition frequency of 100 MHz. Built‑in resistor values are R1 = 4.7 kΩ and R2 = 10 kΩ.
