Diodes are the most elemental of electronic components. Rectifiers are diodes that allow electric current to flow in only one direction. This simple device can be arranged in various configurations to create an array. An array of diodes is a powerful way to direct electric current and signals in differing ways.

SBT100-10G Application Field and Working Principle

The SBT100-10G is a zero recovery Diode Array designed for use in voltage clamping applications. This Diode Array features a low forward voltage drop and low leakage current, making it suitable for a wide range of applications with varying voltage and current levels. It also has a fast switching frequency and can be used in sensitive reset and battery charging applications. The Array ensures protection from over-voltage events, as well as from electrostatic discharge (ESD) and transient voltage spikes.

The array consists of two rectifiers paired in a reverse-parallel configuration. The reverse-parallel configuration allows for increased current capacity at the same voltage ratings. The pair of rectifiers acts together with one undergoing forward conduction and the other one allowing for reverse flow. This arrangement reduces the voltage imbalance between both rectifiers and increases the array’s reliability.

The rectifiers also feature anode isolation to protect each of the rectifiers from each other, as well as increased heat sinkable power. This makes the array suitable for a broad range of applications including automotive, HVAC, power supplies, and LED lighting.

The operation of the SBT100-10G allows a wide range of clamping voltages to be configured with minimal power dissipation, only dissipating enough power to protect the device from over-voltage and over-current events. The device has a typical clamping voltage of 15V and a low forward voltage drop of 500mV when operating at 15A. This helps minimize power loss and provides superior protection for sensitive logic circuits.

In applications with significantly higher clamping voltages, a series resistor can be included to reduce the power loss. The diode array also features stabilizing elements, which reduce the voltage spikes by monitoring the forward voltage changes.

The SBT100-10G is mainly used to limit the peak voltage and current in overcurrent and overvoltage protection circuits. It can also be used as an ESD protection and electrostatic protection. It can be directly connected to a battery input to protect the DC supply circuit from overvoltage, while also offering battery protection and transient protection.

To sum up, the SBT100-10G zero recovery Diode Array is designed for use in voltage clamping applications. It has a low forward voltage drop, low leakage current, fast switching frequency and anode isolation, making it suitable for a variety of applications such as automotive, HVAC, and power supplies. It also offers increased heat sinkable power and stabilizing elements to reduce voltage spikes. The SBT100-10G helps protect circuits from overvoltage and overcurrent events, while also providing ESD, electrostatic and transient protection.
