TVS diodes, or transient voltage suppression, are electronic components designed to protect circuits and electrical components from electrical transients, which are sudden, short-lived spikes in voltage that can occur as a result of a lightning strike, a mechanical effect (such as an inductive load switch), or induced spikes from other sources. The SMB10J28AHR5G is an example of a TVS diode, and is used for many applications.

The SMB10J28AHR5G is a unidirectional silicon-based TVS diode with a peak pulse power rating of 600 watts (10/1000 μs). It is housed in a small, lead-free SMA (Sub-Miniature Adapter) package, which is perfect for space-constrained applications with limited boardspace. This component is primarily used to protect sensitive electronic equipment and components from high-voltage electrical transients, and can be used in many applications, such as telecommunications, networking equipment, automotive control, consumer electronics, and industrial machinery.

The working principle of a TVS diode is simple. When a high-voltage transient appears on the protected line, the diode “clamps” down the voltage to a safe level, thus protecting both the equipment and the components connected to that line. The SMB10J28AHR5G provides protection by clamping the voltage to a maximum of 16V. When the voltage reaches the threshold, it is diverted and dissipated as heat, thus preventing any further damage.

The SMB10J28AHR5G also offers low clamping voltage (Vc) for various working voltages, and has a wide operating temperature range of -65°C to 150°C. It is qualified to AEC-Q101, making it suitable for automotive applications. Furthermore, it is also RoHS-compliant, making it the ideal choice for applications that require high reliability.

In conclusion, the SMB10J28AHR5G is a unidirectional TVS diode that is designed to protect sensitive electronic equipment and components from high-voltage transients. It is housed in a small, lead-free SMA package, and has a peak power rating of 600 watts, making it perfect for space-constrained applications with limited boardspace. Furthermore, it is qualified to AEC-Q101 and RoHS-compliant, making it an ideal choice for applications that require high reliability.
