The APT60S20SG is a heavily doped double-side diffused silicon rectifier diode that is used mainly for its low forward voltage drop and its fast switching features. It is designed for low-loss high-speed switching applications in power supplies and has a maximum forward current of 60A and a maximum attained 60A. Its low thermal resistance makes it ideal for higher current applications. Its maximum peak reverse voltage is 200V. It also has a low incidence of thermal runaway. The APT60S20SG is a large and robust diode with a wide operating temperature range of -55°C to 175°C.

The APT60S20SG has a variety of applications in many different fields. In motor control applications, the diode is used to drive the relays in motor controllers, allowing them to switch on quickly and help reduce motor losses and improve motor speed and torque. The diode is also used in DC power supplies, inverters, and other power switching applications to help prevent arcing and reduce contact heating due to its low forward voltage drop. In power supplies and DC-DC converters, its low thermal resistance provides further beneficial features since it reduces junction temperature and prevents output power degradation.

The diode’s working principle is based on its structure and its physical properties. In its simplest form the device is made up of a single layer of heavily doped semiconductor material. The material is divided into two regions, the Anode and the Cathode, which will be exposed to positive and negative voltages, respectively. When the anode is connected to a positive voltage, and the cathode to a negative voltage, current flows across the diode as holes (which are created by doping) drift through the material.

The diode allows current to pass only in one direction, acting as an electrical one-way street. By connecting the anode and cathode to a voltage source in opposite directions, current will be forced to move through the diode and toward the negative voltage. The built-in electric field of the diode helps to push the flow of electrons in one direction, preventing them from flowing back in the other direction. The diode also has a built-in voltage drop, which helps to regulate the current as it moves through the diode. The diode is extremely fast and efficient in its operation, allowing for quick and efficient switching.

The APT60S20SG is suitable for a wide array of applications due to its low forward voltage drop, fast switching, and its wide operating temperature range. Its ability to resist arcing makes it particularly useful in power supplies and other power switching applications. Its low thermal resistance makes it an ideal choice for higher current applications, and its low thermal runaway incidence make it a safe and reliable device for applications in the motor control and in inverters.
