The SA90C series is a new type of three-port transient voltage suppressor (TVS) diodes. It can be used in a wide range of applications, such as automotive, industrial, and consumer electronics. It offers low capacitance, low leakage and low power consumption. It is a perfect choice for the application in which high-frequency signal transmission is required.

The SA90C is based on a transistor architecture and uses a three-port structure to provide protection against voltage spikes and reverse bias events. When the input signal is below the rated voltages, the SA90C will not conduct, thus providing the desired protection at the input port. The output voltage of the SA90C is a controlled, reverse-biased voltage. It also acts as a series termination resistor to protect against overvoltage situations.

The SA90C diode series provides excellent protection for high-power applications. It has a breakdown voltage of 2V, a peak pulse current rating of 10A, and a power dissipation of 1W. It also has an operating temperature range between -55°C to 125°C making it suitable for large-scale applications.

The working principle of the SA90C series is quite simple. When the input voltage exceeds the rated value, the diode will be triggered. This will cause the low voltage side of the diode to become forward-biased, leading to current conduction. The diode will then convert the excess voltage to heat, thereby protecting the connected circuit.

The SA90C series provides superior protection and efficiency for vehicles, industrial equipment, consumer electronics and other applications. Its low power consumption, low capacitance, and high breakdown voltage make it an ideal choice for these applications. Additionally, its simple three-port structure makes it easy to install, maintain and operate.

In conclusion, the SA90C series provides excellent protection against voltage spikes and reverse bias events. It is a perfect choice for applications which require high-frequency signal transmission. Its simple three-port architecture, low power consumption, and high breakdown voltage make it an ideal choice for vehicles, industrial equipment, consumer electronics and other applications.
