TVS (Transient Voltage Suppressor) is an important component that many products require in order to protect against electrical transients. One type of TVS that has seen a lot of usage within the electronics industry is the BSPD200240D3P. This component has seen a wide range of applications due to its small size, low capacitance, and low leakage current. In this article we will discuss the application field and working principle of the BSPD200240D3P.

The BSPD200240D3P is a mixed technology TVS. This means that it combines both Zener diodes and TransZorb valves (also known as dual series suppression diode arrays) into a single package. Although this type of device is more expensive than a single diode, it provides superior protection against transients and extreme temperatures. The package contains a Zener diode section to absorb energy and reduce noise, along with four TransZorb valves arranged around a central anode lead to dissipate overvoltage and high-frequency transients.

The BSPD200240D3P is designed mainly for use in consumer electronic applications such as set-top boxes, DVD players, and game consoles, as well as low-power data line applications such as USB, FireWire, and LAN. It is also suitable for 12V automotive applications, providing protection against spikes in the ranging from 0 to 35V.

In terms of working principle, the BSPD200240D3P provides protection through both Zener diode and TransZorb valves. The Zener diode portion of the device works by clamping the voltage at its breakdown voltage (BV) as the designed negative or positive, depending on which part of the device is used. On the other hand, the TransZorb portion works by dissipating energy from transients as heat, thus protecting components downstream from the device.

In summary, the BSPD200240D3P is a mixed technology TVS that provides superior protection against transients and extreme temperatures due to its combination of Zener diodes and TransZorb valves. It is mainly used in consumer electronics and low-power data line applications, and works by clamping the voltage at its breakdown voltage as the designed negative or positive, and dissipating energy from transients as heat.
