Transient Voltage Suppression (TVS) diodes are diode-based electrical protection devices that act as emergency voltage protectors. These devices protect sensitive electrical circuits from high-voltage transients caused by electrical noise. The SMCG90A-M3/9AT is a TVS diode that is used for surge protection in products that are subjected to large voltage transients.

The SMCG90A-M3/9AT has a maximum voltage rating of 9A with an optimal clamping voltage of 14V. It can handle up to 5,000W of total power dissipation. The device offers a failure rate of 8ppm/℃ and a high surge capability of 8kV. The operating temperature range is -55℃ to 125℃. The SMCG90A-M3/9AT is available in the miniature SMA package with a lead spacing of 6.5mm. The diode is RoHS compliant and Halogen free, and is UL and cUL recognized.

The application fields for the SMCG90A-M3/9AT include automotive, aviation and aerospace, consumer electronics, optical communication systems, industrial electronics, and power systems. It can be used in LED drivers, automotive ECUs, power supplies, battery chargers and protection circuits, telecommunications, instrumentation, solar energy, and many other applications. The TVS diode can be used in applications as high as 12V for reverse over-voltage protection, automotive ECUs for reverse or over-voltage protection, power supplies and AC/DC converters for transient voltage surge protection, and in battery protection circuits.

The SMCG90A-M3/9AT works by providing a high-current clamping voltage and limiting the voltage applied to the protected circuit. The device has a low clamping voltage which is only activated when a voltage higher than the specified breakdown voltage is applied to the device. Upon activation, the SMCG90A-M3/9AT will limit the ripple voltage peak amplitude to the zener voltage and the over-voltage voltage that will be applied to the protected circuit can be decided by the user. During operation, the current flow is limited to a safe level as the TVS diode has a very low incremental resistance. The SMCG90A-M3/9AT can absorb very high energy and has very fast response times of less than 1ns.

The SMCG90A-M3/9AT is an ideal device for surge protection applications that require a high voltage and ultra-fast response times. The device allows for low power dissipation and is RoHS and Halogen compliant. The device can be used in a wide range of application fields and offers excellent protection in automotive, consumer electronics, power supplies, LED driving, battery chargers and protection circuits, instrumentation, and many other areas. In addition, the SMCG90A-M3/9AT offers high surge capabilities and low clamping voltages in order to safely protect the circuit from over-voltage conditions.
