TVS (or Transient Voltage Suppression) diodes are electronic components designed to provide protection against excessive voltage transients. The SMCG90CA-M3/57T is a turn-off/soft turn-off TVS diode that is used in various applications such as high-speed data lines, LVDS interfaces, telecom and industrial systems, and wherever protection against high voltage transients is needed.

The SMCG90CA-M3/57T operates in two stages. First is the turn-off stage. When its input power is greater than its breakdown voltage, the SMCG90CA-M3/57T will turn-off and suppress the voltage. The second stage is the soft turn-off stage. When the input power is lower than the breakdown voltage but still higher than the breakdown voltage minus the diode\'s clamping voltage, the SMCG90CA-M3/57T will soft-turn-off and suppress the voltage.

The SMCG90CA-M3/57T has a reverse breakdown voltage of 9V, a maximum clamping voltage of 6.2V, and a maximum peak pulse current of 57A. Its Vbr is 8.2V and Its Ih is 5mA. The device is housed in low-profile SMA package that is suitable for surface mounting on PCBs. It has a current rating of 3A and a Power dissipation rating of 10W. The SMCG90CA-M3/57T is designed for operation in temperatures from -55C to 125C.

The SMCG90CA-M3/57T is primarily used for ESD and surge protection on applications like network communication such as EMS, routers, and switches, automotive data lines, portable electronics, consumer electronics such as set-top boxes, and industrial control boards. In addition, it can be used in any application where high speed, low leakage, and high surge current protection are required.

To summarize, the SMCG90CA-M3/57T is a turn-off/soft turn-off TVS diode that offers reliable protection from high voltage transients. It has a reverse breakdown voltage of 9V, a maximum clamping voltage of 6.2V, and a maximum peak pulse current of 57A. The device is housed in low-profile SMA package and features a current rating of 3A and a power dissipation rating of 10W. It is primarily used for ESD and surge protection on applications like network communication, automotive data lines, portable electronics, consumer electronics, and industrial control boards.
