1SMB11CAT3G Application Field and Working PrincipleTVS - Diodes, often referred to as Transient Voltage Suppressors or Transient Voltage Surge Suppressors, are devices used in conjunction with electronic circuits. They are designed to protect circuits from voltage levels that are too high and that could cause damage or degrade performance. TVS - Diodes are essentially an additional "safety" measure for circuits, allowing the circuitry to operate at its intended levels without fear of exceeding limits that could cause damage.The 1SMB11CAT3G TVS - Diode is designed for use in communications systems. It is designed to provide enhanced protection for applications that require low reverse leakage current and fast response. The 1SMB11CAT3G is ideal for applications such as switches, routers, modems, line cards, and access points.The 1SMB11CAT3G has a unidirectional breakdown voltage of 11.25 V and features a very low leakage current. It also has a high-speed response time of under 10 ns and is able to handle surge currents up to 5 amps. This allows the 1SMB11CAT3G to protect against transient overvoltage events including lightning surges, switching surges, and ESD (electrostatic discharge).The way TVS - Diodes work is fairly straightforward. When the input voltage is greater than the breakdown voltage, electrons will be rapidly forced through the diode. This rapid flow of electrons is what leads to the protection of the circuit. The TVS - Diode acts as a "shunt" in the circuit, diverting the voltage away from the sensitive components of the circuit and dissipating it as heat. If the voltage reaches its maximum, the diode will become consumed by the current flowing through it and break down, diverting all of the current and voltage away from the circuit.In summary, the 1SMB11CAT3G is a unidirectional TVS - Diode that provides enhanced protection for applications that require low reverse leakage current and fast response. It has a breakdown voltage of 11.25 V, a low leakage current, and a fast response time of under 10 ns. It is designed to protect circuits from transient overvoltage events and dissipate the voltage as heat when the diode breaks down.
