The SPUSB1AJT is a type of TVS – Mixed Technology designed by SPAK. It integrates multiple technologies, including ESD, EFT and surge protection, in a single package. This versatile device is applicable to a wide range of applications due to its flexibility and competitive pricing.

The device features a discrete-mounted transient voltage suppressor (TVS) array, a resistor array and a thermally-activated fuse. The TVS array provides protection against ESD and EFT events, with clamping occurring at a rated voltage of 8 volts or more. The resistor array allows for a low surge absorption and an adjustable clamping voltage. The combination of these two components optimizes the protection during surge events. The thermally-activated fuse serves as an additional layer of protection during surge events, providing the device with a fast response time and a low trip point.

The SPUSB1AJT is designed for use in a wide range of consumer and industrial applications. It can be used in power supplies, communications equipment, computers and industrial control systems. It is suitable for use in applications where power disturbances occur, such as from lightning and short circuits. Its small size and flexibility allow for easy integration into the application and provide a cost-effective solution for protection against transient voltage.

The working principle of the SPUSB1AJT is simple and straightforward. The TVS array provides the primary protection against ESD and EFT events. It absorbs the transient current and limits the voltage across its terminals to a predetermined operating voltage. The resistor array absorbs excess energy from the surge event and provides additional protection against transient voltage. The thermally-activated fuse acts as an additional layer of protection by providing a fast response time and a low trip point.

In summary, the SPUSB1AJT is a versatile and reliable transient voltage suppressor ideal for a wide range of applications. Its flexibility and competitive pricing make it an attractive solution for protecting against transient voltage events. The device integrates multiple technologies into a single package, including ESD, EFT and surge protection, providing ample protection for critical applications. Its working principle is simple and reliable, providing fast response times and a low trip point.
