This Product Selection Guide contains information to help select products in the Surge Suppession Ics category on DigiKey.com
Surge Suppression ICs are designed to keep electrical devices safe from excess voltage and/or current. Components in this family are designed using semiconductor materials. The characteristics are clamping voltage, technology, number of circuits, applications, and mounting type. The technologies are external or internal switch with the number of circuits being 1, 2, 3, or 4. Target applications are automotive, Ethernet, general purpose, portable equipment, SLIC, USB, USB OTG, and others.
SelectionCharacteristics
Voltage - Clamping: Characterizes the maximum value to which a protection device limits an applied voltage. Measured under manufacturer-defined test conditions.
Technology: Indicates whether it has an internal or external switch.
Number of Circuits: The number of individual channels the device can provide independent protection to.
Applications: Application is the type of equipment or environment the device will be used in, they are tested and typically rated by a third party to ensure certain minimum standards for the application they are intended for.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
