Mixed technology TVS (Transient Voltage Suppressors) such as the BSPD120480D3K have a plethora of application fields and working principles. A TVS acts as a surge protector and diverts high transients of voltage to ground or across a “clamping voltage” to protect sensitive electronics from damage, making them ideal for use in situations where sensitive electronics must withstand a wide range of voltages. The BSPD120480D3K utilizes a unique combination of two different technologies: a series of Zener diodes and Low Voltage Disconnect (LVD).

The Zener diodes act as the main surge protection. They are unable to conduct normal current flow, but when their breakdown voltage is exceeded (the phrase “breakdown voltage” refers to the maximum voltage a device can withstand before it breaks down into breakdown or avalanche mode and conducts current) they enter avalanche mode and conduct current. This ensures that any sudden increases of voltage (indicated by the P dv/dt value) are safely diverted from inputs and outputs of systems.

In addition to the Zener diodes, the BSPD120480D3K uses a complex Low Voltage Disconnect functionality operating in parallel with the Zener diodes. This adds the function of disconnecting components and not just protecting them in cases in which the voltages exceed the P dv/dt setpoint. Low Voltage Disconnect (LVD) is an effective way of preventing complete breakdowns that might be caused by large surges, ensuring that components don’t fail by disconnecting them from a system when a predetermined voltage is exceeded.

So the working principle of the BSPD120480D3K is a combination of Zener Diode protection and Low Voltage Disconnect protection. This makes it ideal for use in a wide range of applications, such as in aerospace, power grid, automotive, telecommunications, home appliance, medical and industrial control systems. It is also suitable for use in high-voltage and high-frequency operations, making it a great way to prevent ESD-related (electrostatic discharge) power surges.

Due to its combination of Zener diodes and LVD, the BSPD120480D3K is also ideal for use in portable devices such as laptops, cell phones, and tablets. These devices are at risk of a wide range of voltage surges due to their frequent use and mobility. The BSPD120480D3K can be used to protect these devices’ circuits by diverting the transients of voltage to ground with its Zener Diode protection and disconnecting them if the voltage surpasses a pre-set shutdown threshold.

The BSPD120480D3K is also suitable for battery-operated equipment, given its low power consumption of only 2.4nA. Its low power consumption ensures that battery life is not affected by transferal of energy, making it an ideal choice for a wide variety of battery-operated applications.

The BSPD120480D3K is a great example of a Mixed Technology TVS due to its unique combination of surge protection by Zener diode and current interruption by LVD. As such, it can be used in a variety of applications, especially ones involving portable devices and battery-powered equipment, and can prevent damage from power surges, ESD, and other voltage abnormalities.
