The device is available in several packaging styles, including TO-252 and SOT-223.

Working Principle of DPLS4140E-13

The DPLS4140E-13 is an NPN transistor, meaning that it operates as an "open" circuit when the base-emitter junction is forward biased, resulting in a low voltage drop across the collector-emitter junction. The device utilizes a "split-collector" arrangement that operates as a "biased diode": current flows through the base-emitter junction when the base-emitter voltage is above the emitter saturation voltage, and current is diverted away from the collector.

When the base-emitter and collector-emitter junctions are both forward biased and the base-emitter junction is forward biased to the point where substantial current flows through it, the transistor starts to saturate. As it saturates, the collector-emitter voltage decreases, lowering the total transistor resistance. This process allows current through the collector-emitter to be increased more than what would have been possible with the forward biased junction alone.

Applications of DPLS4140E-13

Due to the high voltage, high current and wide temperature range offered by the DPLS4140E-13, it is suitable for a variety of applications. Some of the most common applications include:
