TVS-Diodes have been used for decades in the electronics industry. They offer the ability to absorb transient voltages and to protect electronic circuits from damage. One of the most popular TVS-Diodes is the SA36A. This device offers superior protection from potentially damaging transients.

The SA36A is a bidirectional TVS-Diode that is capable of handling a surge of up to 350A while providing active protection from transients that are up to 600 watts. It features a wide operating temperature range, from -55°C to 135°C, and an ultra-low capacitance of just 0.16pF. This makes it an ideal choice for high speed data line applications.

The SA36A application field includes but is not limited to protection against electrostatic discharge (ESD), radio frequency interference (RFI) and lightning surge protection. It is typically used in circuits that require low capacitance and advanced transient protection performance. The SA36A has a high peak pulse power rating of 1000 watts and can handle up to 6.5kW of energy at 10/1000 microseconds, allowing it to effectively suppress transients that result from EMI and other issues.

The working principle of the SA36A is relatively simple. Essentially, its active components are designed to reduce the impact of transient voltage levels by absorbing large amounts of energy without getting damaged. It is able to do so by quickly changing the polarity of its electrodes, which facilitates the flow of electrical current between them. This, in turn, shunts the unwanted transients away from the protected circuit. The SA36A also offers protection against reverse and forward bi-polarity, meaning that it can handle a surge in either direction.

In conclusion, the SA36A is a versatile and reliable TVS-Diode that offers superior protection against transient voltage levels. It features a wide operating temperature range, low capacitance, and an impressive peak pulse power rating, making it an excellent choice for ESD, RFI, and lightning surge protection. Moreover, its operating principle is straight-forward, relying on the quick switching of polarity to absorb large amounts of energy and protect the underlying circuit.
