Rectifiers are widely used to power analog and digital circuits. This type of device has been used in industrial, automotive, and consumer electronic applications due to its ability to convert alternating current (AC) power into direct current (DC) power. A type of rectifier is the Schottky Barrier Diode, abbreviated as SBD, which uses a rectifying junction for its operation. This article focuses on the PD412011 model, an array of 4 SBDs which is widely used for voltage rectification and voltage protection.

Overview

The PD412011 is a 4-channel surface mount array of SBDs housed in a single package. The four independent channels provide full bridge rectification of power circuits and are designed for use with 12V to 55V input voltages and up to 2A current. The PD412011 array is capable of withstanding high surge currents and over-voltage conditions and features low forward voltage drop.

Applications

The PD412011 is widely used in a wide range of applications including automotive, industrial, and consumer electronics. It is commonly used in power supplies, power converters, polishing machines, voltage regulators, laptop and desktop computers, cell phones, tablets, and even wearable devices. It is ideal for use in applications where reliable protection from overload, short circuits, and voltage surges is needed.

Working Principle

The PD412011 is an array of four SBDs connected in a full-bridge configuration. When power is applied to the four diodes, the current from the incoming AC source is rectified and sent to the load. Since the SBDs are bidirectional, a reverse voltage protection is also provided. The forward voltage drop of the PD412011 is usually around 0.6V.

In addition to the rectification function, the PD412011 also provides over-voltage protection. If the voltage of the incoming AC power exceeds the maximum specified voltage (e.g. 55V), the PD412011 will clamp the voltage and limit its flow to the load. As a result, the load will remain safe against potential power surge damage.

Conclusion

The PD412011 is a surface mount array of 4 SBDs which is widely used to provide full-bridge rectification and voltage protection. With its ability to provide reverse-voltage protection, surge current handling, and low forward voltage drop, the PD412011 is an ideal choice for applications that require reliable power conditioning.
