TVS - Diodes Transient Voltage Suppressors (TVS) are vital components in modern electronics, providing protection from transient voltage events that can result from lightning strikes, AC power line surges, and other high-energy sources. The 1KSMB47CA is a TVS DIODE designed specifically to protect sensitive electrical and electronic equipment from electrostatic discharge (ESD) and other high-energy transients.The 1KSMB47CA is constructed out of a silicon-oxide-nitride-oxide-silicon (SONOS) material, which provides a high-quality, high-frequency device for protecting sensitive electronic components. The SONOS structure is a five-layer structure that provides superior protection against a wide range of high-energy transients, including those from ESD, electrostatic accidents, and other sources.The 1KSMB47CA is a unidirectional device, meaning that it will only allow current to flow in one direction; current cannot flow in the opposite direction. This feature makes the 1KSMB47CA ideal for use in applications where only one direction of current needs to be protected, such as in automotive wiring applications where control line currents must be routed through the device.The 1KSMB47CA is designed to protect sensitive electronic devices from transient voltage events by absorbing the voltage spike and dissipating it as heat. This ensures that the delicate components of the equipment protected by the 1KSMB47CA are not damaged by the transient voltage event.The 1KSMB47CA has a peak surge current handling capability of 400A, making it ideal for protection against lightning and other large transient voltage events. The 1KSMB47CA also has a low-capacitance design, making it suitable for use in applications where capacitance is a concern, such as in high-speed data communication lines.The 1KSMB47CA also features a built-in protection mechanism that helps ensure that the device is not damaged by too much current, preventing costly repairs or even equipment failure. This protection mechanism, called a "crowbar circuit," automatically shuts off the device if too much current passes through it.In conclusion, the 1KSMB47CA is a high-quality TVS DIODE that offers superior protection against transient voltage events. Its SONOS construction, unidirectional design, and built-in protection circuit make it ideal for use in a wide variety of applications, including automotive wiring protection and high-speed data communication lines.
