Transient Voltage Suppressors (TVS) are electrical components designed to protect electronic circuits from damages caused by power surges and voltage spikes. TVS Diode refers to a type of diode that includes an integrated protection against overvoltage or electrostatic discharge (ESD). The TVS Diode series includes both unidirectional and bidirectional components.

1SMC54AT3G anti-surge diode is an axial-leaded TVS and belongs to the 1SMC Series. 1SMC54AT3G is a unidirectional TVS diode with low leakage current and a maximum peak pulse power of 540W at 8/20μs waveform. It helps protects sensitive electronic components from transient overvoltages and can withstand high ESD levels.

Application Field: 1SMC54AT3G diode can be utilized in a range of industrial and consumer products, such as portable consumer electronics, telecom equipment, medical devices, wireless devices, computers and other home electronic appliances. Also, it helps protect AC adaptors and integrated circuits from damaged induced by lightning surges or high voltage transients.

Working Principle: When a positive voltage applied to the anode of 1SMC54AT3G diode, the diode will switch off and act as an open circuit. When a negative voltage is applied, the diode will turn on and starts to act as a short circuit, allowing current to flow directly. The maximum rated avalanche current of the 1SMC54AT3G diode is 1.5A, until the diode short-circuits and switches off. The series is designed with an electrostatic discharge rating of 8kV (HBM).

TVS diodes are specially designed and are capable of dissipating high power over a short period of time. They can rapidly clamp excessive voltage and protect sensitive components from high energy transients. 1SMC54AT3G anti-surge diode offers fast response times and can reliably provide protection against overvoltage spikes.
