Details
The 2SD426 is a bipolar junction transistor (BJT) that is commonly used in audio amplifier circuits and other low-frequency applications. It is a silicon NPN transistor with a maximum collector current of 0.5A and a maximum collector-emitter voltage of 25V.The 2SD426 has a low collector-to-emitter saturation voltage which makes it suitable for switching applications where low power dissipation is important. It also has a high current gain (hfe) value which ensures efficient amplification of small input signals.The transistor is housed in a TO-92 package which is a small, through-hole package that allows for easy mounting on a printed circuit board. The 2SD426 is readily available and has a relatively low cost, making it popular among hobbyists and electronic enthusiasts.
