TVS – diodes are an essential component of every electronic system designed to protect sensitive electronics from overvoltage. The DESD32VS2SO-7 is a divergent bi-directional TVS, which provides ESD, surge, and test pulse protection for electronic systems operating at supply voltage levels up to 27V. This device is designed specifically for applications such as automotive systems, industrial systems, and telecom I/O lines.

The DESD32VS2SO-7 has two terminals: anode (A) and cathode (K). The device can manage large and fast transients due to its transient voltage suppression (TVS) capabilities, which allow it to absorb and dissipate a significant amount of energy without causing damage to the system. The device clamps the voltage by switching to its off-state and then slowly discharges the energy, allowing the voltage to reach its original state. This enables it to protect against transients that can occur from ESD, lightning, and other sources of high voltage.

ESD protection is a major application for the DESD32VS2SO-7. It is capable of two types of ESD protection: HBM (Human Body Model) and MM (Machine Model). HBM is used to protect against ESD events caused by human contact, such as those occurring during the assembly of electronic components. The device can absorb a HBM ESD event of up to 20KV between the two terminals. MM is used to protect against ESD events caused by machines, such as those that occur during the operation of electronic equipment. The DESD32VS2SO-7 can absorb a MM ESD event of up to 25KV between the two terminals.

The DESD32VS2SO-7 is also designed to provide surge protection. It is capable of suppressing transients of up to 100A, with a breakdown voltage of 10V. This enables it to protect against IEC 61000-4-5 compliant surges of up to 2.5KV, as well as IEC 61000-4-2 compliant ESD events. In addition to surge protection, the device can also provide test pulse protection. Its breakdown voltage is 6V, meaning it can protect against test pulses of up to 9V.

The DESD32VS2SO-7 is a robust, reliable, and fast switching TVS diode that can provide ESD, surge, and test pulse protection for automotive, industrial, and telecom electronic systems. Its two terminal design allows for easy installation, while its clamping effect ensures that the system is protected against transients. With its high transient current rating and ESD protection capabilities, it is a great choice for applications that require reliable and effective protection against overvoltage.
