Switches
A switch is a device that allows electricity to flow through a circuit by completing or interrupting the connection. It is a common component in electrical and electronic systems and is used in a variety of applications, such as controlling the flow of electricity in a circuit, turning devices on and off, and routing electrical signals. One of the primary use cases for switches is to control the flow of electricity in a circuit. This can be done by manually flipping the switch or by using a control mechanism, such as a timer or a sensor. Another common use for switches is to turn devices on and off. This can be done using a switch that is built into the device or by using a separate switch that is connected to the device. In addition to these basic use cases, switches can also be used to route electrical signals. For example, a switch can be used to route a signal from one device to another or to direct a signal to a specific circuit or component. If you're looking for a wide variety of switches for your projects, flux.ai has the world's largest community-driven public library of them. The library includes footprints, symbols, datasheets, and simulation models for a wide range of switches, making it easy to find the right switch for your needs.
SM8S33A
Automotive 6.6 kW Surface-Mount TVS Diode – Unidirectional transient voltage suppressor (TVS) diode designed for automotive electronics, industrial power supplies, DC power rails, telecom equipment, battery protection, load dump suppression, and embedded circuit protection applications. The Littelfuse SM8S33A features a 33 V reverse standoff voltage (VRWM), 36.7 V minimum breakdown voltage, and 53.3 V maximum clamping voltage at a 132 A peak pulse current (10/1000 µs). Rated for 6.6 kW peak pulse power dissipation, it provides robust protection against ESD, lightning-induced surges, inductive switching transients, and automotive load dump events.
