A Transient Voltage Suppression Diode (TVS) is a device that is designed to protect electronic circuits from high-voltage, high-current transients. This type of device is most commonly used in the automotive, industrial and communications fields. One of the most popular types of TVS devices is the SMPC28AN-M3/H. This TVS diode offers a low on-state voltage, low capacitance and high power rating. The SMPC28AN-M3/H is suitable for protection against high peak current spikes.

The SMPC28AN-M3/H is a Unidirectional (ULSAB) transient voltage suppression diode. This means that the TVS diode is only able to conduct current in one direction, making it suitable for use in applications where reverse polarity may be present. The device has an internal connection which facilitates the suppression of negative going transients.

The working principle of the SMPC28AN-M3/H is as follows. When the input voltage rises above a predetermined level, the TVS diode begins to conduct. The internal circuitry then activates, clamping the voltage across the device and redirecting the current away from the protected circuit. Once the source of the transient voltage is removed, the TVS diode ceases conducting and the TVS diode returns to its non-conducting state.

The SMPC28AN-M3/H is ideal for applications in automotive systems, communication systems and systems exposed to high levels of EMI/RFI. This type of TVS diode can be used to protect circuits from high voltage transients, including transients caused by electrostatic discharges and inductive switching. The SMPC28AN-M3/H is also suitable for use in industrial systems, where it can be used to protect circuits from short-term over-voltage spikes.

The SMPC28AN-M3/H is well-suited for automotive applications such as ABS brakes, body control modules and engine control units. In communication systems, the SMPC28AN-M3/H can be used to protect equipment from high peak current transients caused by lightning strikes and other EMI/RFI sources.

In summary, the SMPC28AN-M3/H Transient Voltage Suppression Diode is a popular choice for protection against high voltage, high current transients. The SMPC28AN-M3/H is a Unidirectional (ULSAB) TVS diode which operates by clamping the voltage across the device and redirecting the current away from the protected circuit. This type of TVS diode is most commonly used in automotive, industrial and communication applications, where it can be used to protect equipment from EMI/RFI sources and short-term over-voltage spikes.
