TVS diodes provide surge protection against voltage transients induced by lightning and other sources. TVS diodes are designed to protect sensitive electronic components from damage due to electrical surges. The PGSMAJ100A R3G is a TVS diode used to protect high-speed data lines from ElectroStatic Discharge (ESD) and other transient voltage events. This diode provides high-speed response, low leakage current, and low steady-state clamping voltage.

The PGSMAJ100A R3G is an unidirectional diode of the Transil family, specifically intended for the protection of high speed data lines during ESD surges. This diode can protect data and transmission lines from voltage transients up to 40A peak and 5A continuous. The device has a high surge capability of up to 12kV. In addition, the PGSMAJ100A R3G has a low capacitance (4pF typical) which ensures fast response times and less signal degradation.

The PGSMAJ100A R3G works by clamping the voltage induced by transients to a safe operating level. This is done by using the diode’s junction capacitance which stores the energy of the transient and then releases it slowly. This limits the voltage to a safe value, protecting the circuit from damage. In addition, the diode is able to transfer the energy of the transient to a resistor which dissipates it in the form of heat. This prevents damaging current spikes.

The PGSMAJ100A R3G is typically used in applications such as automotive on-board systems, automotive body electronics, audio/video systems, mobile phones, and other consumer electronics. This diode is able to provide reliable ESD protection performance over the entire operating temperature range of -40°C to 125°C.

The PGSMAJ100A R3G is a versatile TVS diode providing effective surge protection for a wide range of applications. This device offers fast response times, low leakage current, and low steady-state clamping voltage, making it an ideal choice for protecting sensitive electronics from unexpected voltage spikes.
