TVS (Transient Voltage Suppression) diodes provide surge protection against transient voltage events such as electrostatic discharge (ESD), lightning, and line surges. TPD8S009DSMR is a diode with a bidirectional transient voltage protection (TVP) and is designed to protect both high voltage and low voltage applications.

Applications

TPD8S009DSMR is designed for a wide variety of applications, including communication ports, automotive, medical, consumer, industrial, and computing devices. This TVS diode device is used for providing surge protection against transients that can cause destruction on integrated circuits, buses, and other sensitive components. Additionally, this device is used for limiting voltage transients in any of the AC/DC power line and galvanic isolation applications.

Advantages

The advantages of TPD8S009DSMR include flexible and robust transient voltage protection, high-level power trip point, and a low leakage current. This diode is available in a low-profile package and features an extended frequency response. Furthermore, it features a 40V breakdown rating and operates from -55°C to 150°C. Moreover, the TPD8S009DSMR offers high peak and static clamping capability, with a high frequency response of up to 1GHz.

Working Principle

TPD8S009DSMR works by clamping over-voltages to the manufacturer’s specifications. It works by using a breakdown voltage of 40V and a clamping peak voltage of 35V while offering a low clamping capacitance of 3.2pF. During a transient voltage event, the TPD8S009DSMR quickly clamps the over-voltage from the device’s supply rail.

When a surge current reaches a certain peak value, the TPD8S009DSMR quickly lowers the device’s supply rail voltage and clamps the peak voltage to its rated value. This prevents damage to the device from the transient event. This protection works in both positive and negative surge directions.

Conclusion

The TPD8S009DSMR is an excellent, high-performance diode for surge protection. It provides surge protection in both high and low voltage applications and is used to protect sensitive components from potential destruction. This diode offers a high peak and static clamping capability and a low leakage current. Furthermore, it features a 40V breakdown rating and operates from -55°C to 150°C. Additionally, its low-profile package and extended frequency make it an ideal solution for a wide variety of applications.
