The V40D120CHM3/I from Vishay is a rectifier array with integrated free-wheeling diode and support circuit. It offers superior surge testing capability and reliable performance in high power applications. It is suitable for use in high frequency (up to 10kHz) power supplies, and motor control applications in motor drives, UPS systems, and other industrial equipment. The array is available in both through-hole and surface-mount packages.

The V40D120CHM3/I consists of four independent Chassis Mount Fast Recovery rectifiers and one integrated free-wheeling diode integrated in a single package. The rectifier array provides a low forward voltage drop and a fast recovery time, while the integrated diode helps dissipate switching spikes generated by inductive loads. Additionally, the array contains two zener diodes in series to provide transient protection.

The V40D120CHM3/I is designed to operate in both AC and DC applications. In AC applications, it functions as a rectifier by rectifying the incoming AC signal and converting it to DC. In a DC application, it acts as a free-wheeling diode, preventing current from flowing in the reverse direction. In this application, the array acts as a flyback diode, helping to limit the voltage spike caused by the inductive load when the power is shut off.

The V40D120CHM3/I offers excellent performance, reliability and safety. It is designed to deliver up to 1.2 kW of power, with a forward voltage drop of just 0.44 V, a reverse current rating of 1 A and a surge capability of 9 A. It also has a wide operating temperature range of -40°C to +85°C and can withstand high surge and transient voltages.

The V40D120CHM3/I is ideal for high power applications such as motor drives, UPS systems, motor control and other industrial equipment. It provides a cost-effective solution for system designers who require reliable, safe and efficient power conversion. It offers reliable surge testing capability and is available in both through-hole and surface-mount packages.
