TVS - Mixed Technology

The BSPD400600Y3K is a unique type of mixed-technology TVS (transient-voltage-suppressor) component. It is designed for applications where fast response to voltage transients and reliability are essential. The component is a combination of a metal-oxide varistor (MOV), a common diode, and a surge-absorbent diode. This combination of technologies provides superior surge protection and fast response to transients.

Application Field

The BSPD400600Y3K is suitable for use in applications where transients can result in damage or data loss, such as process automation systems, home appliances, telecommunication systems, automotive systems, and other electronic circuits that require surge protection. It can be used to protect circuits from surges of up to 600 volts, with a maximum surge current of 8.3 amps (nominal 8/20 µs waveform).

Working Principle

The BSPD400600Y3K is a three-in-one solution, combining a metal-oxide varistor, a common diode, and a surge-absorbent diode. The metal-oxide varistor (MOV) is designed to absorb the high-voltage transients. It does this by allowing current to pass through it when the applied voltage exceeds a certain threshold (the breakdown voltage). The common diode is designed to protect against bi-directional transients. The surge-absorbent diode is designed to protect against higher-energy transients, such as lightning strikes. The components are connected in series, allowing them to work together to provide a fast, reliable protection against voltage transients.

The BSPD400600Y3K is designed such that it can be connected either directly to the protected circuit, or in series with a fuse. When connected in series with a fuse, it provides a fast protection response to transients, while the fuse acts as a secondary protection mechanism in case of an extended surge.

The BSPD400600Y3K is designed for reliable protection of sensitive electronic circuits and systems. It has excellent surge protection capabilities, fast response times, and low thermal runaway. It is an ideal choice for applications where fast response to transients and reliable protection are essential.
