2SD1803S-E Description

Short technical summary and product information.

The 2SD1803S-E is an NPN bipolar junction transistor manufactured by On Semiconductor (onsemi). It is designed for high-current switching applications, with a maximum collector-emitter voltage of 50V and a maximum collector current of 5A (8A pulse). The device offers a low collector-emitter saturation voltage of 400mV at 3A, enabling efficient operation in switching circuits.

 

Key electrical characteristics include a DC current gain (hFE) of 140 to 400 at 500mA and 2V, a gain-bandwidth product of 180MHz, and an output capacitance of 40pF. The transistor can dissipate up to 20W when the case temperature is held at 25°C, and operates at junction temperatures up to 150°C.

 

The 2SD1803S-E is housed in a TO-251-3 (IPak, TO-251AA) package with short leads, suitable for through-hole mounting. This package is compact and slim, making it suitable for space-constrained designs. The device is intended for relay drivers, high-speed inverters, converters, and other general high-current switching applications.

 

With its high current capability and fast switching speed, the 2SD1803S-E is a practical choice for power management and switching circuits where efficiency and reliability are important. The through-hole package simplifies prototyping and manual assembly in many industrial and consumer applications.
