TVS (Transient Voltage Suppressor) diodes, also known as Transil diodes, are used in electronics to protect sensitive circuits from transient excessively high voltage created by electrostatic discharges (ESD) or inductive loads. The SLD8S20A is a TVS diode used to protect equipment against ESD. It is designed to meet the RoHS standard and is suitable for board-level protection of Conducted ESD. It has low and stable reverse leakage, and is reliable and fast for protection against ESD pulses.

The SLD8S20A TVS diode is a 20V, 8-pin diode with a peak pulse power of 8kW. Its fast response time offers excellent protection - in less than 1 microsecond. This makes it especially suitable for consumer electronics, such as digital cameras, computers, and mobile phones, as well as industrial and automotive applications. The SLD8S20A has a low leakage current and is suitable for use in a wide operating temperature range of -40°C to +125°C.

In order to understand the SLD8S20A’s working principle, it is important to understand the four stages it goes through during operation: suppression, breakdown, clamping, and recovery.

The suppression stage happens at the moment a voltage is applied to the diode, and the diode is designed to absorb the voltage and suppress it. The breakdown stage occurs when the voltage exceeds the diode’s breakdown voltage. When the voltage reaches this level, an avalanche breakdown occurs and the diode conducts current.

In the clamping stage, the voltage on the diode rapidly decreases, due to the current created during the breakdown stage. This allows the surge to be stopped after a short time. Finally, during the recovery stage, the diode returns to its blocking voltage and the current decreases until it reaches its original low value.

The SLD8S20A TVS diode is a reliable device that is ideal for board-level protection against ESD. It offers a fast response time, low leakage, and wide operating temperature range. There are many applications where the SLD8S20A would be ideal, such as consumer electronics, industrial, and automotive, and it is suitable for a range of voltages. The SLD8S20A is a reliable and cost-effective solution for protecting sensitive circuits from ESD and voltage surges.
