The SMBJ28CD-M3/H is a transient voltage suppressor (TVS) diode specifically designed to protect sensitive electronic circuits from voltage spikes, transients, and over-voltage events. This device has a wide operating voltage range, from 6.5V to 36V, and can handle a large peak pulse current of up to 28A. It has a low junction capacitance and reverse leakage current, making it an ideal choice for protecting high-speed data lines from damaging voltage spikes.

The SMBJ28CD-M3/H works by clamping the voltage spikes to an acceptable level. When a voltage spike occurs, the TVS diode will force the excess voltage away from the circuit, preventing it from damaging it. This effectively serves as a secondary “fuse,” since the excess current is safely diverted away from the circuit and the device can reset itself once the voltage has been brought back to a safe level.

The TVS diode can be used in a wide range of applications, including industrial systems, automotive control units, IT and telecom systems, consumer electronics, and medical equipment. As its wide operating voltage range and high peak pulse current makes it suitable for high-speed signal lines. The device also has a low on-state resistance, which helps reduce power consumption and ensures efficient power management in sensitive circuits.

The SMBJ28CD-M3/H is designed to be easy to install and integrated into existing systems. The device is hermetically sealed to protect it against water, dust, and other contaminants. It also features a built-in over-voltage shutoff, which automatically switches off when the voltage surpasses the rated limit. This is especially useful for circuits which are vulnerable to frequently occurring voltage spikes, such as those found in automotive systems.

In conclusion, the SMBJ28CD-M3/H is a versatile TVS device suitable for a wide range of applications. Its wide operating voltage range and high peak pulse current ensures it is capable of handling most voltage spikes with ease, while its low on-state resistance and hermetic design make it ideal for power management in sensitive circuits. The device\'s built-in over-voltage shutoff is also a useful feature which helps protect vulnerable circuits from potentially damaging voltage levels.
