TVS-Diodes or Transient Voltage Suppressors (TVS) are electronic components used in the automotive, telecom, and industrial applications which help protect sensitive electronic circuits and systems from the effects of electrical transients, ESD, and spikes. SMF4L24A is a type of TVS diode with a voltage clamping of 24V, making it suitable for a wide array of applications in almost any industry. In this article, we’ll discuss its application field and working principles.

SMF4L24A is a low capacitance transient voltage suppressor suitable for use in motor control, industrial or medical electronic circuits that require protection against overvoltage and ESD transients. Its dual-diode design provides extremely low leakage current while affording bidirectional protection for positive and negative surges. The device is available in a 0.47” footprint, allowing for easy implementation in applications that require limited space but require protection from voltage surges.

But what makes SMF4L24A ideal for protecting automotive and industrial systems? First and foremost, it provides protection for circuits subjected to repetitive ESD or EMI/RFI transients up to 8kV contact and 15kV air discharge. This allows the TVS diode to guard against voltage transients and spikes caused by variable loads, heavy switching, and other common events in an industrial or automotive setting. The diode’s low capacitance of just 0.1 pF also ensures that the signal will remain uncompromised, without any distortion following signal transients or absorption.

In terms of the device’s actual working principle, the SMF4L24A functions by providing a low-impedance path for current that is generated by voltage transients or spikes. This keeps the circuit current from increasing to unsafe levels, and in the event that the spike is particularly high, the device will enter a clamping state to further protect the equipment. During clamping, the diode will effectively limit the voltage that reaches the equipment, preventing any damage or malfunction. Typically, the clamping voltage is set to a level that is just 1-2V higher than the normal operating voltage, allowing for the circuit to function properly without any significant interference.

Due to its low capacitance, low clamping voltage, and excellent multi-directional protection, the SMF4L24A is ideal for a range of automotive and industrial applications, including motor control, powering circuits for electric vehicles, and protecting medical equipment from sudden voltage changes. It can easily be implemented in almost any circuit, and its compact size ensures it won’t take up valuable space in the system. If you’re looking for a reliable solution for protecting your automotive or industrial electronics against voltage transients and spikes, the SMF4L24A is certainly worth considering.
