SDP1300Q38B is a relatively cost effective and efficient TVS – Mixed Technology solution, designed to protect networks and sensitive components including PC motherboards, direct-broadcast satellite setups, LCD displays, and audio/video amplification circuits from overvoltage surges and transients.  It is capable of providing excellent protection from damage due to transient inrush and over-voltage events.

The SDP1300Q38B is comprised of two major components, a voltage-transient suppressor and a voltage-clamp circuit. The device is designed to protect the motherboard\'s low-voltage circuitry from high voltage transients that occur during on-off or power supply switching. The device consists of a three-lead SDP1300Q38B, which is a low voltage, low resistance protection device, and an MOSFET with a diode to clamp any high-voltage transients.

The SDP1300Q38B is capable of suppressing voltage transients up to 40kV and features a surface-mount design with an integrated power MOSFET that helps to reduce the design overhead of having to source, design, and integrate a separate MOSFET circuitry. The design also features a low turn-on voltage, low leakage current, and low gate-charge, which contributes to increased performance.

When subjected to a high-voltage transient, such as a lightning strike or an electrostatic discharge (ESD), the device will quickly clamp the transient voltage and discharge it to ground. This limits voltage stress on the sensitive components of the system as the transients are quickly dissipated into the ground. It provides excellent protection from voltage surges caused by power failure, power rerouting, and even short circuits.

The SDP1300Q38B also helps to reduce the overall cost of system protection, as it is a single device with all components integrated into it. This helps to significantly reduce the device count, thus reducing the number of board components needed to assemble the system. The device also helps reduce installation time, as a single device solution requires only minimal double-sided PCBs and assembly time.

The SDP1300Q38B is an efficient and reliable technology that is designed to protect sensitive electronic components from voltage surges and transient voltage events. It is capable of providing an excellent protection from overvoltages and offering competitive pricing when compared to other Voltage Transient Solutions. Other benefits of using this device include its low turn-on voltage, low leakage current, low gate-charge, and surface-mount design, which provides superior cost savings while providing a high-level of protection against overvoltage and ESD events.
