The V40PW45C-M3/I is an array of diodes manufactured by Littelfuse and designed for a wide range of application areas. The device can be used in medium and high power applications including rectifiers, voltage and current regulators, snubber circuits, and over-voltage protection circuits. The V40PW45C-M3/I is the latest offering from Littelfuse, and offers exceptional performance in the areas of power dissipation, current handling capability, and thermal resistance.

The V40PW45C-M3/I is a high power Schottky array consisting of four sets of two parallel diodes, each of which is rated to withstand a maximum current of 40A. Each diode in the array is protected against reverse breakdown stress through a built-in protective circuit. The package measures 5.1 x 5.1 x 5.1 mm, and the total area is just 0.26 in2, making it ideal for space-constrained applications.

The V40PW45C-M3/I operates in a configuration known as a bridge rectifier, which provides full-wave rectification for AC power sources. It consists of two diodes connected in series, with the other two connected in parallel with the diodes in series. When AC power is connected to the rectifier, the alternating current is converted to direct current in three steps: the first two diodes conduct on the positive half-cycle and the other two on the negative half-cycle; the average voltage is then regulated by the average current in the two pairs of parallel diodes; and finally, the two pairs of diodes in the bridge rectifier maintain the DC current in a steady state.

In terms of protection features, the V40PW45C-M3/I provides a soft start surge protection feature under stressful AC voltage conditions. This feature limits the inrush current during start-up, and helps to ensure that the reference current does not exceed a maximum limit. This prevents unnecessary power dissipation and eliminates the risk of thermal runaway due to uncontrolled current. The surge protection circuit also helps to reduce the over-temperature risks, as it automatically shuts down the device if the temperature rises above its safe operating limit.

The V40PW45C-M3/I is suitable for a wide range of applications, including industrial machinery, appliances, power supplies, automotive systems and medical equipment. The device’s high power shutdown performance makes it an ideal choice for over-voltage protection, voltage and current regulator circuits, and snubber applications. With its compact package, excellent thermal resistance, and high power handling capability, the V40PW45C-M3/I is an ideal solution for a range of industrial applications.
