DTC143XEBHZGTL

This is an NPN pre-biased digital transistor (also known as a resistor-equipped transistor) manufactured by ROHM Semiconductor. It integrates a 10kΩ base resistor, simplifying circuit design by reducing component count. The transistor features a collector current rating of 100 mA and a collector-emitter voltage (Vceo) of 50 V. With a minimum DC current gain (hFE) of 30 at 10 mA and 5 V, it provides reliable switching performance. The maximum Vce saturation voltage is 300 mV at 500 µA base current and 10 mA collector current. The transition frequency (fT) is 250 MHz, making it suitable for high-frequency switching applications. Power dissipation is rated at 150 mW. This device is designed for surface mount assembly, offered in the SC-89 (SOT-490) package, with supplier package EMT3F (SOT-416FL). It is RoHS3 compliant and has an MSL rating of 1 (unlimited). Typical applications include general-purpose switching, inverter circuits, and interface circuits where a pre-biased transistor reduces external component count.
