TVS - Diodes, also known as Transient Voltage Suppressors, are devices designed to protect against transient overvoltage events. PGB2010402KRHF is a type of TVS diode. It is designed to protect sensitive electronic equipment from the damaging effects of Electro-Static Discharge (ESD).

PGB2010402KRHF is a small surface mount device, composed of a special semiconductor material. This material is made with a unique layer of insulation, which helps to absorb electrical discharges and dissipate their energy quickly and safely. PGB2010402KRHF devices are designed to operate within the DC spectrum from 4V to 140V and under an operating temperature range of -55°C to 125°C.

The working principle of PGB2010402KRHF is based on the concept of avalanche breakdown. This is a process in which a sudden increase in the voltage across the component causes the current to flow heavily through it. The device\'s internal resistance when flowing current will increase exponentially. This causes a large portion of the excess energy to be dissipated by the component and limits the voltage surge that passes through the rest of the circuit.

The PGB2010402KRHF is primarily used in applications that require overvoltage protection. Some examples are: personal computers, home theaters, telecom equipment, industrial machinery and Industrial Control Systems (ICS). This device can also be used for mixed signal protection, such as providing protection for both digital and analog input signals. Its low capacitance, low inductance, high frequency response, and high dV/dt limit, make it well suited for these applications.

The device must be carefully chosen to ensure that the operating voltage of the device matches the voltage that it is expected to protect against. PGB2010402KRHF devices have a stand-off voltage of 10V, with a max peak pulse voltage of 15kV. This means that they should be appropriate for standard ESD voltages of up to 2kV.

In conclusion, PGB2010402KRHF is a type of TVS diode designed to protect electronic equipment from transient overvoltage events, such as ESD. It works by dissipating excess energy in the form of heat, and limiting the amount of voltage that passes through the circuit. It is well-suited for applications such as personal computers, home theaters, and Industrial Control Systems, and should be chosen according to the expected operating voltage.
