Transient voltage suppression diodes (TVS-Diodes) are important tools in protecting modern electronic systems from overvoltage events. The 1KSMBJ130A is a unidirectional, bi-directional, and multi-directional silicon-based surface-mount TVS-diode designed to protect mobile and automotive electronic circuits from overvoltage events.

The 1KSMBJ130A is a unidirectional TVS-diode with a voltage rating of 130V and a power rating of 1.6W. It offers a low operating voltage of 5V and a low clamping voltage of 15.4V. The 1KSMBJ130A has a fast response time of 1.0ns and it is capable of handling repetitive transient pulses up to 100A. The 1KSMBJ130A also offers a high surge current capability of 1000A. The 1KSMBJ130A is available in two packages - a 0408 SOT-23 (standard outline) and an MSOP-8 (mini small outline package).

The application field of 1KSMBJ130A includes protecting automotive and mobile electronic systems from overvoltage events. It can be used in electronic components such as automotive DC-DC converters, generators, and battery chargers, mobile phone antenna modules, and personal computers. The 1KSMBJ130A can also be used in other applications such as communications, consumer electronics, and gaming systems.

The working principle of 1KSMBJ130A is based on the avalanche breakdown. When the applied voltage exceeds the breakdown voltage, an avalanche current begins to flow through the device. This current is controlled by the device’s reverse bias to limit the current flow, while also providing a clamping voltage that is independent of the applied voltage. When the applied voltage drops below the normal operating voltage, the current stops flowing, thus clamping the voltage and protecting the device.

The 1KSMBJ130A is an effective way to protect electronic systems from overvoltage events. It offers fast response time and high surge current capability, and it is available in two packages. The 1KSMBJ130A is suitable for applications such as automotive and mobile electronic systems, communications, consumer electronics, and gaming systems.
