Transient Voltage Suppressors (TVS) are devices used to protect electronic circuits against transient voltage spikes. They act as a surge protection device, providing a low-impedance clamping action that prevents excessive current levels from damaging sensitive components in electronic systems. TVS Diodes are one of the most widely used types of transient voltage suppressors. The SMF85A RVG is a TVS Diode designed to provide reliable protection from transients up to 400V peak transient voltage.

The SMF85A RVG TVS Diode is a unidirectional diode offering very low capacitance and fast clamping response, making it an ideal solution for protection of peripherals, data, and signal lines in a wide range of electronic systems. Its protective features include a low stand-off voltage of 5.8V and a maximum peak pulse power rating of 9kW. The device also offers improved ESD protection, with a clamping voltage of 68V at an ESD 15V contact discharge.In terms of its physical package, the SMF85A RVG is a SOT-363 package for automated pick-and-place mounting processes. It has eight terminals, with a typical junction capacitance of 10pF, making it suitable for high-speed switching applications. The SMF85A RVG TVS Diode operates on the principle of a voltage-limiting device. When an overvoltage is detected, the device limits the current flow by forward biasing the diode and clamping the voltage across it to a safe level. This helps to protect the sensitive components of the electronic system from damage due to excessive current flow.The SMF85A RVG TVS Diode can be used in a wide range of applications, including consumer electronics, automotive electronics, telecom systems, power supplies, and industrial systems. It is REACH and RoHS compliant, making it an environmentally friendly device. The SMF85A RVG is also designed for applications where electrical transients are expected to occur. It can help prevent damage to the system due to voltage spikes that can occur due to switching operations, cable discharge, or other transient events. Additionally, the device can help protect against Electrostatic Discharge (ESD) that can occur due to human handling or other sources of electrostatic charge. In summary, the SMF85A RVG TVS Diode is an ideal solution for protecting sensitive components in electronic systems from transient voltage spikes and ESD events. It offers a low stand-off voltage, fast clamping response, and improved ESD protection, making it suitable for a wide range of applications. Due to its low junction capacitance and versatile SOT-363 package, the device is easy to use and provides reliable protection against ESD and transient voltage events.
