TVS - Mixed Technology

TVS (Transient Voltage Suppressors) technology is a well-known electrical component that is used to protect electrical systems from damage due to transient voltages. TVS technology has been broadly utilized in system designs throughout many different industries. One of the newest products in this type of protection is the SDP0640Q38B Transient Voltage Suppressor/MOSFET. This device combines both TVS protection and MOSFET (Metal Oxide Semiconductor Field Effect Transistor) switching capability in a single package.

The SDP0640Q38B was designed to provide a single-package solution for high-voltage transient voltage protection and low on-resistance MOSFET switching. It is an evolution in TVS technology and offers protection up to 600W in the industry\'s smallest form factor. The device utilizes a packaged MOSFET to eliminate the need for external switching components, making it ideal for high-temperature application in space-constrained environments.

SDP0640Q38B Applications

The SDP0640Q38B is ideally suited for a variety of applications, including power management, high-speed data and video devices, automotive systems, communication systems, industrial systems, consumer electronics, military and aerospace, as well as general purpose equipment. Because it can support up to 600W transient voltage, this device is ideal for protecting circuits against surge, noise, and ESD events. These features make the SDP0640Q38B a great protection solution for high-voltage systems.

SDP0640Q38B Working Principle

The SDP0640Q38B operates on the principle of a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) device which switches between its two states of ON and OFF. In the ON state, current flows from the source to the drain. In the OFF state the current between the source and drain is blocked. The SDP0640Q38B is unique in that it incorporates both the MOSFET switching function and the TVS protection into one package. This combination provides an efficient design solution as well as high protection against voltage transients.

The TVS portion of the device acts as an over-voltage protection device. It will provide current limiting and clamping down of the voltage to a safe level, thereby providing protection from surge, noise, and ESD. The MOSFET switching capabilities of the SDP0640Q38B allow users to switch from one state (e.g. ON to OFF) or vice versa (e.g. OFF to ON) without the need for external components, saving space, time and money.

The SDP0640Q38B is a versatile, high voltage transient voltage suppressor/MOSFET that offers effective protection and switching capabilities in the same compact package. This innovative product is ideally suited for applications in power management, high-speed data and video devices, automotive systems, communications systems, industrial systems, consumer electronics, military and aerospace, and general purpose equipment.
