MXLSMCJ7.5AE3 Circuit Protection

TVS - Diodes are a class of PN junction diode devices that are specifically developed for protection of integrated circuitry from high voltage transients induced by electrostatic discharge (ESD). The MXLSMCJ7.5AE3 is a TVS diode designed for protection of sensitive components on circuit boards from voltage spikes and surges. This diode is especially suited for use in critical electronic circuitry to protect components against spikes that occur due to lightning, when connecting the system to an AC power source, or during periods of system downtime.

Application Field

The MXLSMCJ7.5AE3 has a low stand-off voltage and an ultra-low capacitance of 0.4pF, making it ideal for high-value sensitive circuit board components. This diode is especially useful for protecting sensitive components from high voltage transients that can occur due to Lightning. In addition, this diode is used to provide a degree of additional protection against in-rush current, which can occur when AC power is connected to a system. The diode is also useful for preventing damage to digital circuitry from over-voltage. The device can be applied to data interface and telecom lines, and also to protect powerful processor ICs from ESD and IEC61000-4-2 indirect lightning strikes.

Working Principle

The MXLSMCJ7.5AE3 diode features an ultra-low capacitance (0.4pF) and a low stand-off voltage which prevents damage to sensitive components connected to the device’s input/output pins. This diode is designed to absorb and clamp high voltage transients and its stand-off voltage prevents any further current flow into the circuit board. The clamping voltage of the diode is determined by the breakdown voltage of the diode device. When the peak voltage of the transient exceeds the breakdown voltage of the diode, the diode will start conducting current from the diode’s cathode to its anode, thus absorbing and clamping the current from the transient and preventing any further damage to the circuit board.

Conclusion

The MXLSMCJ7.5AE3 is a class of TVS diode, specifically designed for protection of sensitive circuit board components. This diode features an ultra-low capacitance and a low stand-off voltage, which allow it to absorb and clamp high voltage transients. This diode can be used to protect delicate components from damage due to over-voltage, ESD, and lightning. It is also useful for preventing in-rush current when connecting AC power to the system. This device is ideal for protecting data interface and telecom lines as well as powerful processor ICs from ESD and IEC61000-4-2 indirect lightning strikes.
