ESDSLC5V0D3B-TP (Transient Voltage Suppressor - Diode) is an electronic component used for providing an over-voltage and reverse-polarity protection. It is mainly used in computing and communication devices in order to protect against high voltage surges or abortive events such as those produced by lightning. The device is mainly composed of two silicon junctions formed in a single wafer, the first providing the blocking capability of the diode, and the second the voltage-limiting operation. The ESDSLC5V0D3B-TP is available in both through-hole and surface mount packages.

The application field of ESDSLC5V0D3B-TP includes: digital equipment power supply, mobile phone, PDA and other mobile products protection, power transformers, power supply lines, adapter protection, solar power supply, server power input, etc. The most typical application scenario is the built-in lightning over-voltage protection circuit in the power input jack of the electronic product, or the lightning surge protection of the signal line.

The basic working principle of the ESDSLC5V0D3B-TP consists on the ability of its junctions to activate and turn the limit current of the diode on when subjected to a surge voltage that exceeds its breakpoint. This current, in addition to the internal resistance of the device itself will cause a voltage clamping in the non-destructive component, avoiding the issue of possible structure damage.

The device has a maximum peak pulse power rating of 500W, allowing dissipates energy up to hundreds of joules. Furthermore, this device has a low capacitance characteristic, typically less than 10pf, thus avoiding the propagation of high frequencies and radio frequencies, as well as high peak current pulses.

The ESDSLC5V0D3B-TP was designed for ultra-low capacitance applications, presenting a significantly low error rate and providing excellent clamping performance, making it one of the best transient voltages suppressors. Therefore, it is suitable to applications in which low capacitance and fast response time is needed in order to protect sensitive components.

In conclusion, the ESDSLC5V0D3B-TP is an excellent over-voltage and reverse-polarity protection device. It is mainly used for providing protection against lightning-induced surges or abortive events in a wide range of applications such as power supply lines, adapter protection, server power input, etc. This device presents an ultra-low capacitance characteristic together with a fast response time, and provides excellent clamping performance.
