TVS diodes, also known as transient voltage suppression diodes, are electrical components used to protect sensitive electronic circuits from damaging electrical surges. The TV50C640JB-G is a unidirectional surface mount TVS diode specifically designed to protect electronic components and systems against electrostatic discharges (ESDs) and electrical transients. This diode is capable of withstanding repetitive surge currents of up to 8A for 10/1000 μs. It is ideal for automotive applications where transient voltage levels can exceed 6kV.

The TV50C640JB-G TVS diode is a two-terminal, bidirectional, surface mount device. It consists of two paralleled main diodes connected to two opposite terminals. The two terminals of the diode are connected in parallel with the terminals of the circuit. When a transient voltage is applied to the parallel circuit, the diode rapidly switches and the surge current is diverted to ground. This diverts the transient voltage from the protected circuit and reduces its amplitude.

The TV50C640JB-G TVS diode is designed to provide an optimized combination of surge current handling and ESD protection. It is capable of dissipating power levels of over 800W and can survive up to 8A repetitive surge currents. The diode incorporates a unique integrated spark gap that produces an effective spark gap opening voltage of 5.4V. This ensures that the diode opens quickly when subjected to an ESD event.

This diode is ideally suited for a variety of automotive, industrial, and consumer applications where ESD and transient surge protection is required. It is particularly useful in applications involving hazardous high voltages. In automotive applications, this diode can protect automobile components from power-up surges caused by vehicle start-up. In consumer devices, this diode can protect against power supply transients caused by lightning and external power supply transients.

The TV50C640JB-G TVS diode has a very low leakage current of less than 5mA and a maximum forward voltage of 1.6V. It is available in a variety of packages including SOT-89, SOT-23, and DFN-4 packages. The diode has a maximum reverse voltage of 4V and is capable of operating at temperatures ranging from -55°C to +150°C.

The TV50C640JB-G TVS diode is an integral part of any circuit protection system. It provides superior protection against transient voltage surges and ESDs, ensuring that sensitive electronic components remain safe from damage. Combining a high surge current rating with a low voltage and reverse breakdown characteristics, the diode can be used in virtually any high-voltage, low-power environment.
