TVS (Transient Voltage Suppression) diodes are devices designed to provide protection from electrical surges, transients and spikes. The MXLSMLJ85A is an uni-directional low-capacitance TVS diode designed to protect sensitive electronic components and systems from transients over a wide range of operating conditions. It is suitable for high-speed data line protections, Ethernet, USB 3.1/3.2/3.3, Audio, Video and Mass Storage systems and it provides robust ESD suppression.

The MXLSMLJ85A is a breakdown diode that stops unwanted voltages from entering or exiting an electronic system. When its cathode voltage is exceeded, it begins to conduct and absorbs any energy that exceeds the protection voltage, effectively stopping transients from entering or leaving the system. It is available in an 8-pin surface mount package with a VBR of 8V-18V and can provide up to 2000 watts of power protection.

In normal operating conditions, the TVS diode acts as an open switch, allowing current to pass through the part without any voltage drop, however when high voltage transients occur, the diode will latch-on and start clamping the voltage between its breakdown voltage and its peak power. This prevents further voltage increases, protecting the connected components from excessive and damaging voltages.

The MXLSMLJ85A offers exceptional performance for ESD and surge protection, with a guaranteed peak power rating of 2000 Watts at 8/20 us waveform and a guaranteed clamping voltage of 9.8 to 16V. Its low capacitance of 0.8pF and 0.2nA guaranteed leakage current also make it ideal for a wide range of protection of high-speed data lines. The diode has a 100pF discharge port to ensure high discharge rates during high peak pulse events and provides a fast response time of 4V/ns.

Its low leakage current and wide operating temperature range make it suitable for a range of applications, including computers, peripherals, audio visual equipment and automotive applications. The massive 8-pin SMT package also makes it a great option for any type of circuit board design, and its superior ESD protection ensures your sensitive electronics are well-protected against ESD events.

In summary, the MXLSMLJ85A is an ideal solution for providing surge and ESD protection in a wide range of applications including computers, peripherals, audio visual equipment and automotive applications, due to its low capacitance, high power rating, wide operating temperature range and fast response time. It is also available in an 8-pin SMT package, making it an ideal choice for any type of circuit board design.
