ROHM Digital Transistor, 50 V NPN 100 mA Surface Mount SOT-346, 3-Pin DTC143ZKAT146

ROHM DTC143ZKAT146 is a digital bipolar NPN transistor optimized for switching and amplification in digital circuits. It supports a maximum collector-emitter voltage of 50 V and continuous collector current of 100 mA. Encapsulated in a surface mount SOT-346 package with 3 pins, it enables efficient PCB mounting and high-density applications.

The transistor integrates one or two resistors internally, facilitating direct drive from digital logic signals and reducing external component count. With a power dissipation of 200 mW, it maintains stable operation under industrial use cases including electronic devices, automation systems, and signal processing modules.

This device has a minimum gain (hFE) of 80, a low saturation voltage of 300 mV, and supports operating temperatures up to 150°C, making it suitable for harsh environments. Its compact dimensions of 3 mm by 1.8 mm by 1.3 mm save space in compact circuit boards.

The surface mount SOT-346 package allows for automated assembly on production lines. Includes integrated bias resistors termed "digital transistors" for easy interfacing with microcontrollers. Ideal for switching, amplification, and digital driving applications in various electronic and industrial sectors.

Complies with RoHS environmental standards ensuring lead-free manufacturing. Compact size and robust thermal limits support high-reliability design requirements.
