TVS (Transient Voltage Suppressors) diodes are devices used for protecting sensitive electronics from voltage spikes, including those caused by electrostatic discharge (ESD) and inductively induced voltage (surge). The SM15T36CA-M3/9AT is a product of Vishay Intertechnology, sourced from their VDRM series of three-terminal diodes.

The SM15T36CA-M3/9AT is a double-diode, metal can TVS diode with a 4.4 Watt voltage rating and 2.6 Watt peak power rating. It is designed to protect sensitive electronics from transient voltage up to 15V, making it suitable for automotive, industrial and commercial applications.

In order to better understand the purpose and working principle of the SM15T36CA-M3/9AT, it is helpful to be familiar with its features and specifications. The device has an operating junction temperature range of -55℃ to 175℃. This means it is suitable for use in extreme temperatures. It also has a low breakdown voltage of 15V, making it suitable for use in a wide range of applications. Further specifications include a maximum diode capacitance of 6.3 pF and an average surge current rating of 4 A.

The SM15T36CA-M3/9AT TVS diode works by using a large junction diode to protect open-circuit voltage transients. The large junction diode absorbs the transient voltage, which limits the voltage applied to the protected circuit. In addition, when the current passes through the diode, an electric field is created. This electric field acts to suppress peak or repetitive transients. This suppressive function in turn limits the voltage rise applied to the protected circuit.

The SM15T36CA-M3/9AT is suitable for a wide range of application fields, including automotive, industrial and commercial applications. In automotive applications, the device is useful for protecting sensitive electronic components from voltage transients caused by ignition, alternators, and starters. In industrial applications, the diode can be used to protect DC circuits from voltage transients caused by power supply disturbances. It can also be used to protect AC circuits from transients caused by lightning or switching. It is ideal for commercial applications due to its low breakdown voltage of 15V. This makes it suitable for use in LED lighting, electronic vending machines, office automation systems, POS systems, and vending machines.

To sum up, the SM15T36CA-M3/9AT is a TVS diode designed for use in automotive, industrial, and commercial applications. It is capable of effectively protecting sensitive electronics from voltage transients up to 15V. The device works by absorbing the transient voltage, creating an electric field that limits the voltage rise applied to the protected circuit. This makes it suitable for a wide range of applications such as LED lighting, electronic vending machines, office automation systems, POS systems, and vending machines.
