SA36 Circuit Protection

A TVS diode is an electronic device primarily used to protect sensitive electronic devices from excessive voltage. One such device is the SA36 TVS diode, which is designed to protect against discharges and voltage spikes.

The SA36 is a small diode that performs a key role in protecting electronic devices from transient voltages. The diode works by shorting out any transient voltage that is greater than the clamping voltage, thus protecting the device from damage. The SA36 also features an internal avalanche breakdown, which allows the device to quickly react to overvoltages.

The SA36 is constructed of silicon semiconductor material to allow voltage to easily pass through. It features two electrical contacts—an anode and a cathode—that apply an electric field that is used to prevent any high voltage from entering the protected circuit. The diode will then clamp voltage at a level that won’t cause any further damage to the protected electronic device.

The SA36 is designed to provide protection in a variety of applications. It can be used in power supplies, telecommunications equipment, industrial machinery, and other electronic systems. The device is commonly used in equipment that requires a transient voltage protection network that prevents overvoltage conditions from developing and damaging system components.

The SA36 is designed to handle high peak currents and surge voltages. It has a wide operating temperature range, which allows it to be used in both indoor and outdoor applications. The diode is rated for use at a reverse working voltage of 30V, while the maximum peak pulse power is 800W. It also has a low capacitance of 14pF, which helps to minimize propagation delays.

The working principle of the SA36 TVS diode is based on the avalanche diodes. When the forward voltage is applied, the drain-source voltage is applied to the avalanche diode, allowing it to increase the current. This in turn increases the electric field. The increased electric field causes the avalanche diode to break down, allowing the reversed voltage to be rapidly clamped at a level that won’t cause any damage to the protected electronic device.

The SA36 is an effective and reliable diode suitable for a variety of applications in the area of transient voltage protection. Its ability to quickly react to overvoltages and its wide operating temperature range make it a popular choice for use in many electronics systems.
