TVS (Transient Voltage Suppression) diodes provide protection for electronic devices on sensitive voltage inputs from large transients caused by electrical over-stress (EOS) such as ESD (Electro-Static Discharge), spike and other disturbances. An SMBG6.5HE3/52 is a unidirectional (UK) transient voltage suppressor diode, commonly used as an overvoltage protection device. It is a diode with a breakdown voltage of 6.5V and a forward voltage of 0.77V (at 1mA). It offers protection against EOS transients up to 1.5kV (positive or negative).

The SMBG6.5HE3/52 can be used in a variety of applications where protection against EOS transients is essential. The most common application is for the protection of electronic components or devices such as microcontrollers, digital logic circuits, memories, processors, voltage regulators, and power transistors from overvoltage due to EOS. It can also be used in automotive,industrial and medical applications where overvoltage protection is necessary.

The working principle of the SMBG6.5HE3/52 is quite simple. The diode acts as a voltage clamp by clamping the voltage to a safe value, thus preventing damage to the connected components from overvoltage. When the applied voltage reaches the breakdown voltage of the diode (6.5V in this case), the diode will start conducting, clamping the voltage to a safe value. After the voltage has been clamped, the diode will stop conducting and the voltage will return to normal. The SMBG6.5HE3/52 features a high surge capability (1.5kV) and a low leakage current, ensuring that it can be used in a wide range of applications.

In summary, the SMBG6.5HE3/52 is a unidirectional (UK) transient voltage suppressor diode, offering protection against EOS transients up to 1.5kV. It is commonly used for the protection of electronic components from overvoltage due to EOS and its working principle is quite simple: clamping the voltage to a safe value when the applied voltage reaches its breakdown voltage. This diode has a high surge capability and a low leakage current, giving it a wide range of applications.
