SA85CAHA0G Circuit Protection

TVS-Diodes are an important part of any circuit that needs protection from sudden, large surges of electricity, such as those caused by power fluctuations, lightning strikes, or inductive switching. The SA85CAHA0G is a special type of TVS-Diode specifically designed for Automotive and High Reliability applications. It provides protection from high level transient voltages and currents while allowing normal circuit operation to continue as expected.

The SA85CAHA0G is a multi-stranded diode array, able to perform in both unidirectional and bidirectional modes, which makes it a great choice for Automotive applications. It is designed to have very fast response times, typically less than 5ns, meaning it can protect a circuit from damaging overvoltages almost instantaneously. Its peak pulse power rating is up to 1500W at 10/1000µs, ensuring superior protection from transient voltages. The SA85CAHA0G also has an impressive standoff voltage, with a maximum of up to +/-60V, as well as a very low clamp voltage that is typically less than or equal to 6V.

The SA85CAHA0G is also designed with a low-package resistance, making it suitable for high AC current levels. It is easy to install and requires no additional circuits or components. Its unique design allows for a very low profile, which is optimal for high-density applications in tight spaces. It is also incredibly durable, with a maximum operating temperature range of up to 150°C and a rugged housing that can withstand harsh environments.

The working principle behind the SA85CAHA0G is quite simple. When a surge of electricity occurs, the diode array quickly detects it and clamps the voltage to a maximum of 6V, protecting the circuit from damage. This is achieved by diverting the excess electrical current away from the circuit and providing a low-impedance path for the current to flow through. The SA85CAHA0G is an efficient device and can provide maximum protection up to 1500W per diode.

The SA85CAHA0G is an excellent choice for Automotive and High Reliability applications, and its fast response times, low Standoff voltage, and impressive peak power ratings make it ideal for protecting circuits from high voltage surges. Its small size and low profile make it great for space-constrained applications, while its superior durability ensures it will provide protection for years to come.
