Transient Voltage Suppressor (TVS) diodes, also known as transil diodes, are electronic components specially designed to protect against high voltage transients or surges. Typically, a TVS diode behaves like an ordinary diode until the peak voltage across its terminals exceeds its peak inverse voltage (PIV) rating. At this point, the diode will begin to conduct current in both directions and, in a typical application, the capacitor will be discharged rapidly, destroying the transient.

As its name implies, the SMF8.0AT1 is a 8V unidirectional Transient Voltage Suppressor (TVS) based on the SMF Series of ultra-low capacitance silicon avalanche technology. This diode has a forward voltage drop of 0.45V (at 8A) and a reverse-standoff voltage of 8V, making it ideal for mobile device applications. It also offers a high peak pulse power capability of 8kW (10/1000µs waveform) and an integrated over-voltage protection (OVP).

The working principle behind a TVS diode is simple. When a transient voltage is applied to the diode, the diode conducts current in both directions, which is then discharged through the capacitor. This in turn reduces the overall voltage across the diode, providing the desired protection against the transient voltage. The SMF8.0AT1 diode offers superior protection against ESD (electrostatic discharge) and EFT (electrical fast transients) with its 0.45V forward voltage drop and 8kW peak power capability.

The main application field for the SMF8.0AT1 is the mobile device market such as smart phones, PDAs, MP3 players and other devices that may be exposed to high-voltage transients or surges. The device can also be used for automotive and consumer electronics applications. In these applications, the SMF8.0AT1 acts as an effective surge protector, offering both protection and reliability.

The SMF8.0AT1 is designed to be an ideal component for mobile device applications, offering robust protection, low voltage drop, and a high peak pulse power capability. With its integrated over-voltage protection (OVP), it is ideal for high-voltage applications that require superior protection against ESD and EFT. The SMF8.0AT1 provides superior protection and reliability in a wide range of applications, making it an ideal choice for any device needing high-voltage transient protection.
