TVS (Transient Voltage Supressor) diodes are specialized devices designed to protect sensitive electronics from transient voltage levels. The SMP15A-M3/84A TVS diode is designed specifically for use applications where transient voltage levels may exceed the ratings of other standard diode types. It is designed to provide high current surge protection and excellent clamping performance while limiting device size and cost.The SMP15A-M3/84A is a unidirectional device that can be used in any orientation. It has a breakdown voltage rating of 15V and a maximum clamping voltage of 10V. The device also has a fast rise time and low clamping capacitance for reduced device stress. The maximum peak surge current rating is 30A for a 10/1000μs impulse waveform and 6A for a 8/20μs waveform, both with a 1.3V maximum clamping voltage and 10V breakdown voltage.The device is suitable for use in a wide range of applications, including automotive, medical, industrial and consumer. It can be used in input, output and protection circuits. It is also suitable for use in portable devices, such as smartphones and tablets, and in high-speed data line protection.In automotive applications, the SMP15A-M3/84A can be used to protect the car\'s electronic control unit (ECU) from voltage surges caused by the alternator or spark plug system. In medical applications, the device can be used to protect sensitive patient monitors or other medical electronics from voltage spikes. In industrial applications, the device can be used to protect sensitive components from voltage transients caused by industrial machinery.The SMP15A-M3/84A works by clamping the voltage to a safe level once it exceeds the breakdown voltage of the device. The voltage is then limited to the maximum clamping voltage, thus protecting the sensitive electronics. The device also has a fast response time, which ensures that it will limit the voltage before too much damage is done to the protected circuit.The working principle of the SMP15A-M3/84A is based on the electrical breakdown of the diode\'s junction. When the voltage across the diode exceeds the breakdown voltage, electrical breakdown occurs, allowing a large current to flow. This large current causes the voltage to be clamped to the maximum clamping voltage, thus preventing damage to the protected circuit.In summary, the SMP15A-M3/84A is a unidirectional TVS diode designed for use in a wide variety of applications. It provides high current surge protection and excellent clamping performance while limiting device size and cost. The device has a fast response time and low clamping capacitance for reduced device stress. The working principle of the device is based on the electrical breakdown of the diode\'s junction, allowing the maximum clamping voltage to be reached when the voltage across the diode exceeds the breakdown voltage.
