The 2SC4487S-AN is a single-channel transistor, one of the many types in the bipolar junction transistor (BJT) family. This type of transistor has the ability to operate in both central and active regions, making them extremely versatile and adaptive. As a single-channel transistor, it is differentiated from its multi-channel counterparts as it has a single main central current path that is managed and cycled through the other channels. The 2SC4487S-AN has an efficient framework and useful application field, so let’s take a closer look at the device and how it works.

2SC4487S-AN Application Field

The 2SC4487S-AN is primarily used as a switching circuit to control large currents, often in high-defimultion television switching power supplies. However, its application extends beyond TVs to include amplifiers, optical switch control, interface control, and more. In addition to its incredible versatility, the 2SC4487S-AN has a large maximum rating at 80V and a wide operating temperature range of -40°C to 125°C. These features give it a higher tolerance for inrush current and increased reliability in large circuit applications.

In addition to its above mentioned expandability and reliability, the 2SC4487S-AN also offers a low ON-resistance at about 0.45ohms which can be used for low voltage operations of up to 25V. This makes it an ideal choice for controlling current and voltage variables or providing a high-speed switching solution. This device also includes a light-coupling system that allows for effective signal transmission, further expanding its use potential.

2SC4487S-AN Working Principle

The 2SC4487S-AN works on a simple principle to regulate the flow of current through the four connected terminals. The two central terminals, called the emitter and collector, are connected to the power source. This power is then pulled through the two outer circuits, resulting in a flowing current through the entire device. This current is managed and switched by manipulating the signal on the gate terminal. When a voltage applied to the gate terminal exceeds the threshold voltage of the device, the resulting electric field produces a suction force. This electrostatic force therefore opens up a conductive path between the source and the drain. The net result is that the entire current is pulled through the 2SC4487S-AN and is regulated according to the gate signal.

Overall, the 2SC4487S-AN is an effective and efficient small transistor that is easy to integrate into a wide range of large circuits. The combination of its wide operating range, versatile application potential and the simple working principle make it an ideal choice for regulating current, voltage, and switching circuits. With this device, you can easily and confidently control large electrical currents in any electronic application.
