Transient Voltage Suppressors (TVS) are semiconductor devices that protect electronic circuits from voltage transients. The SMF58A-TP is a type of TVS diode specifically designed to protect medium power electronic circuits from transient voltages. It is specifically suitable for applications that require circuit reversal protection for high speed data signaling, surge voltage and noise transient protection.

The SMF58A-TP TVS diode is a five terminal, unidirectional device, with two suppressor inputs and one suppressor output. It is rated at a peak pulse power of up to 5A and a pulse width of 10us. It is also rated for a maximum peak pulse voltage of 16V, a maximum rated operating temperature of 125 degrees Celsius and an operating frequency range of up to 30MHz.

The SMF58A-TP works by absorbing and dissipating excess voltage. When transient voltages are detected, it acts as an ohmic resistor, allowing current to flow through it and thus dissipating the voltage spike as heat. It works on the principle of providing a short circuit between the two suppressor inputs and the suppressor output to absorb and dissipate excess voltage.

The SMF58A-TP is ideal for applications that require voltage protection from transient voltage spikes, such as over-voltage protection, in-rush current protection, ESD protection, reversal protection for high speed data signalling, and surge voltage and noise transient protection. It is also suitable for a wide range of devices, including computers, cellular phones, automotive electronics, industrial equipment, and more.

The SMF58A-TP provides a fast response time of up to 15ns, ensuring protection is given rapidly and protecting expensive components from damage. It is also a low-profile device, measuring only 2.6mm x 0.9mm. Additionally, it is a RoHS-compliant part, making it both an economical and environmentally-friendly choice of TVS diode.

In summary, the SMF58A-TP from Littelfuse is an ideal TVS device for protecting medium power electronic circuits from transient voltages and is suitable for a wide range of applications. With its fast response time and low profile design, the SMF58A-TP is a reliable and economical option for anyone looking for voltage protection.
