The PD412211 Rectifier Array is a series of diodes designed to protect electronic devices from the intrusion of electrical overcurrent and reverse electronic polarity. It acts as an electronic circuit breaker and is meant to operate at a safe level to keep the surrounding electrical system from being damaged by excessive currents or polarity reversals. This device is also known as a Shunt Rectifier, which indicates its purpose – to divert excess current away from the circuit.

The PD412211 Rectifier Array is particularly well-suited for protecting high-power consumer and commercial electronics against short-term, high-voltage power surges and reverse current surges. High voltage power surges can occur when the electrical system first comes on or off at the beginning or end of the operation. When used in a consumer or commercial environment, they can be used to help protect circuits from overload and reverse-current surges, and to help provide fail-safe measures when an unanticipated current overload occurs.

The PD412211 Rectifier Array’s arrangement of two diodes and one capacitor provides a secure and reliable solution to protect electronic components from excessive and reverse-currents. This arrangement simplifies the circuit design as only two diodes and a capacitor are needed to protect against both types of current. In this configuration, the diode provides a secure, low-conductance path to divert the incoming current while the capacitor slowly charges up and prevents the circuit from overloading in high-current situations. The capacitor helps to ensure that the voltage between the two diodes never exceeds the rated voltage of the device, helping to protect the circuit from harm.

The PD412211 Rectifier Array has a wide range of applications, including high-voltage switching, automatic swapping of high-current power supplies, reverse-polarity protection and even general-purpose electronic protection. In high-voltage switching, the Rectifier serves as a switch to divert the voltage from one polarity to the other, protecting the circuit from high-current overloads or dangerously high voltages. This can also be used for automatic switching between high-current power supplies, preventing the possibility of overloads. In addition, this device can be used for reverse polarity protection, allowing power to flow in only one direction and preventing ‘hot swapping,’ as polarity reversal can often lead to shocks, as well as damage to components and devices. Finally, the PD412211 Rectifier Array can help protect general-purpose electronic devices from short-term surges due to its short circuit current rating, helping to provide a reliable layer of protection to valuable equipment.

To ensure the correct installation and operation of the PD412211 Rectifier Array, there are certain specifications and precautions that must be met, such as the device contact resistance and the maximum voltage of the device. The resistance of each diode should be tested before installation, as having a too-high resistance can lead to improper operation due to the inability of the device to properly regulate the incoming current. Additionally, the device should not be exposed to a voltage in excess of its rated voltage as this can cause physical damage to the device.

In summary, the PD412211 Rectifier Array is a reliable and cost-effective solution for protecting electronic devices from overloads and reverse-currents. Its unique arrangement of two diodes and a capacitor simplify the circuit design, help provide a secure and reliable protection layer, and the device contact resistance and the maximum voltage of the device must be checked before installation. The Rectifier Array can be used in a variety of applications, from high-voltage switching, reverse polarity protection, and general-purpose protection, protecting valuable electronic components from damaging currents.
