TVS – Diodes play a crucial role in protecting sensitive electronic devices from transient voltage spikes caused by electrostatic discharges and lightning strikes. These components are sometimes referred to as transient voltage suppressors (TVS), which are a form of rectifier that protect sensitive electronics from voltage spikes.

1KSMBJ47A is a type of a highly reliable, low-power, surface-mounted, dual-diode transient voltage suppression (TVS) device that helps to control the transient voltage phenomenon. It is an AEC-Q101 qualified TVS device designed to protect sensitive electronic equipment from damage caused by overvoltage transients. This device has a response time of less than 1.0ns and operates over a broad range of voltages, from 6.0V to 48V.

The 1KSMBJ47A is available in SOT-23 surface-mount packages and is designed for use in automotive applications. Its datasheet indicates that the device has a maximum peak pulse power of 600W (10/1000 μs) and an excellent thermal stability. Moreover, it features a low clamping voltage of 23.6V at an 8A surge current and has a break-down voltage of 26.4V.

The working principle behind the 1KSMBJ47A is quite simple. When an electrical device is exposed to a transient voltage, the 1KSMBJ47A begins to conduct and redirect the excess current away to reduce the voltage observed at the protected devices. This ensures that any electrical device connected to the 1KSMBJ47A remains protected from transient voltage spikes.

The 1KSMBJ47A is able to provide up to the 600W of peak pulse power protection, thus making it a suitable choice for protecting a wide range of automotive applications. Moreover, its low current leakage, fast response time, low profile design, and excellent thermal stability make it a very reliable TVS device for various commercial electronics applications.

In conclusion, the 1KSMBJ47A is a reliable and cost-effective TVS device ideal for protecting automotive applications from transient voltage spikes. By using the 1KSMBJ47A, you can protect sensitive electrical devices from damage caused by overvoltage transients. Moreover, this device offers excellent thermal stability, low current leakage, fast response time, and excellent peak pulse power protection.
