SM5S13AHE3_A/I

TVS (Transient Voltage Suppressors), also known as surge suppressors, are electrical components used to protect sensitive components from high voltage spikes. The SM5S13AHE3_A/I is a single-channel TVS diode designed to protect circuits from transients generated by physical shocks, electrostatic discharge (ESD), and overvoltage. This device features an ultra-low capacitance for ultra-high-speed signal attenuation and an 8 kV peak pulse power (10/1000 us) for ESD protection.

SM5S13AHE3_A/I Application Field

The SM5S13AHE3_A/I is designed for use in an automotive environment, such as in-vehicle networks and electronic control units, as well as in industrial and consumer applications. This component is well suited to protect automotive networks and diagnostic connections as well as audio equipment, photo and video equipment, and communication equipment.

SM5S13AHE3_A/I Working Principle

The SM5S13AHE3_A/I features an ultra-low capacitance for ultra-high-speed signal attenuation and protection from ESD. When a high voltage transient occurs, the device will clamp the voltage, limiting the current that flows and protecting the protected device from damage. The device is designed with two zeners connected in reverse to form a bidirectional clamp. When the transient reaches the breakdown voltage of the zeners, the voltage across the protected circuit is limited and the current is diverted away from the protected load.

The device constructed with ultra-low capacitance helps attenuate high frequency transients and allows the device to protect the signal from high frequency spikes. The device also features a low reverse leakage current and low clamping voltage to help minimize the risk of damage to sensitive electronics. Additionally, the device includes a high-voltage breakdown rating that ensures it will not fail even during extremely high voltage and current conditions.

Conclusion

The SM5S13AHE3_A/I is a single-channel TVS diode designed to protect circuits from transients generated by physical shocks, electrostatic discharge (ESD), and overvoltage. It features an ultra-low capacitance, 8 kV peak pulse power, and a high breakdown rating for reliable protection from high voltage transients. The device is well suited to protect automotive networks, diagnostic connections, audio equipment, photo and video equipment, and communication equipment.
