The MXLLCE15A is a type of TVS (Transient Voltage Suppression) diode optimized for bidirectional ESD (Electrostatic Discharge) protection applications. This diode utilizes the ThinQ! reverse geometry technology to enable ultra low capacitance without compromising on surge capability. It is suitable for ESD protection up to 20 kV Level 4 per IEC 61000-4-2 Contact and Air Discharge.

The MXLLCE15A can be used in a wide variety of ESD protection applications, such as handheld portables, computer peripherals, USB, video, audio, HDMI, Ethernet, automotive, and power systems. It is a compact, low capacitance diode that provides superior protection for sensitive ICs and connectors in a dense environment.

The working principle of the MXLLCE15A is based on the voltage clamp concept, where the transient surge current is routed through the diode in the reverse direction. When the voltage across the diode exceeds the breakdown voltage, the diode will turn on, and the current will be limited to a safe level. The ThinQ! Reverse Geometry technology enables very low clamping voltage even at high transient currents.

The MXLLCE15A has a low capacitance of 0.3pF typical. This allows for minimal signal attenuation, even at high frequencies. The peak pulse power rating is 500W, and the maximum surge current rating is 36A. The breakdown voltage range is from 6V to 12V. This diode also features an integrated internal resistor for thermal stability under high surge current conditions.

The MXLLCE15A also features a low leakage current of 10uA maximum. This allows it to be used in low power applications, such as automotive and portable electronics. The device also has a low thermal resistance, making it suitable for high power applications, such as power supplies and other energy management applications.

The MXLLCE15A is an excellent choice for ESD protection in many applications, due to its low capacitance, high surge capability, low leakage current, and low thermal resistance. It is an ideal choice for high density board designs, and can be used to protect sensitive electronics from ESD damage.
