TVS - Diodes Overview

The TVS or transient voltage suppression (TVS) diode is a type of diode specifically designed to protect electrical systems from voltage spikes. TVS diodes are used in a variety of applications such as power supplies, protection circuits, and data lines. With their broad range of uses, TVS-diodes are often found in consumer, medical, and military electronics.

What is the 1KSMB130A?

The 1KSMB130A is a TVS diode that is used to protect sensitive electronic systems from overvoltage conditions. It is composed of a silicon epitaxial planar construction. It is packaged in a SMA package and rated for Operating Temp -55 C to + 150 C .The 1KSMB130A is composed of a zener diode in series with a transient-suppression diode, providing better ESD protection than standard bidirectional TVS diodes.

1KSMB130A Application Field

The 1KSMB130A is mainly used in the protection for the equipment against Electrostatic Discharge (ESD), and electron burst, and surge pulse such as lightning. It is mainly used on car electronic systems such as airbags, central locking, audio/video systems, immobilizers, and power control units. The 1KSMB130A is also used in consumer electronics such as digital cameras, cell phones, and cordless phones. Additionally, it can be used in many other applications such as computers and industrial electronics.

1KSMB130A Working Principle

The 1KSMB130A operates by providing a sudden path to ground for transient voltages. It is composed of two components: a Zener diode and a transient-protection diode. The Zener diode is used to limit the maximum voltage on a circuit, while the transient-protection diode helps to absorb any remaining voltage above this level.When a surge voltage is applied, the Zener diode rapidly conducts its current out of the circuit and the transient-protection diode then helps absorb the remaining surge voltage. This helps protect the electrical systems from any damage caused by transient voltage spikes. The 1KSMB130A is a popular choice for surge protection, as it\'s capable of absorbing more than 65 Amps of peak surge current.

Conclusion

The 1KSMB130A is a TVS diode designed for the protection of sensitive electronic systems from overvoltage conditions. This diode has a wide range of applications, from automotive electronics to consumer electronics. It is composed of two components—a Zener diode and a transient-protection diode—which work together to absorb any surge voltages that are applied on the circuit. This helps protect the electrical systems from damage caused by these transient voltage spikes, making the 1KSMB130A a popular choice for surge protection.
