Working Principle

The V20DM120 is a rectifier array that includes four discrete anti-parallel rectifiers connected together. The device is manufactured using advanced high-voltage silicon technology and contains four rectifiers. A thermal resistance junction-to-case and a diode forward voltage drop is typically included.

The diodes in the V20DM120C-M3/I rectifier array are designed to be connected in anti-parallel to each other, thus providing a bidirectional path for current flow. When an input signal is applied, the rectifier allows for current to flow in the positive direction (in the direction of the arrow on the device) but blocks current from flowing in the opposite direction. During this process, a voltage drop occurs across the diode which is typically shown as the device\'s Forward voltage drop.

To effectively protect the device from potential damage, each device is usually covered by an integrated Schottky barrier protector which acts as an overvoltage transient protection (OVP). This protects the device from situations when the input or output voltage exceeds the device\'s maximum ratings.

The device is also covered by a thermal resistance junction-to-case which helps to dissipate heat away from the device and maintain its operating temperature. For better performance, the V20DM120C-M3/I is temperature-compensated with a temperature coefficient of 0.5mV/°C.
