This Product Selection Guide contains information to help select products in the Transistors - Special Purpose category on DigiKey.com
Products in the special purpose transistor family are discrete transistors or transistor arrays, with or without additional integrated passive components and internal connections, that are intended for or adapted to some narrow or specific purpose such as current mirroring, balancing series connected capacitor banks, or load switching.
SelectionCharacteristics
Transistor Type: Enumerates product characteristics such as polarity, number of devices incorporated in a package, internal connections among devices, etc.
Applications: Application is the type of equipment or environment the device will be used in, typically they are tested and rated by a third party to ensure certain minimum standards for the application they are intended for.
Voltage - Rated: Typically this represents the maximum voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components.
Current Rating (Amps): Typically this represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Mounting Type: Indicates how the device is mounted.
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 supplier 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.
