MXLSMBJSAC18 Circuit Protection

TVS (Transient Voltage Suppressor) diodes are semi-conductor components used to protect electrical and electronic systems from overvoltage events. The MXLSMBJSAC18 ultra-low capacitance (UL) transil diodes belong to this family and are specifically designed for ESD, EFT and surge protection of high-speed data lines in automotive, aerospace and industrial applications.

The MXLSMBJSAC18 TVS diode features a mini-SMD (123 mils) configuration and an extremely low capacitance of just 0.65 pF. It also provides high peak pulse power of up to 38 A (10/1000s) and a low clamping voltage for increased surge immunity. The diode has a maximum operating voltage of 18V and a reverse leakage current of less than 100nA at 8V.

The working principle of the MXLSMBJSAC18 TVS diode is quite simple. When an overvoltage occurs, the diode redirects the pulse current to ground and provides a low resistance path for the excess voltage. This helps to protect the connected system by quickly clamping down the high voltage before it gets a chance to damage the system’s components. The diode is highly effective in protecting against ESD, EFT and surge-induced electrical disturbances.

The MXLSMBJSAC18 TVS diode is suitable for use in a wide range of application fields. It is particularly well-suited for high-speed data lines in automotive, aerospace and industrial environments, and is also ideal for protecting various electronic circuits, including RS-232 (serial) and USB (Universal Serial Bus) interface circuits. In addition, this diode is compatible with lead-free reflow conditions and offers excellent EOS (electrical over-stress) immunity.

The MXLSMBJSAC18 TVS diode provides superior protection against system failures caused by overvoltage conditions. Its advanced features, including its mini-SMD configuration, low capacitance and high peak pulse power, make it an ideal solution for ESD, EFT and surge protection of high-speed data lines in automotive, aerospace and industrial applications.
