The MASMCJ11A diode is a member of the Transient Voltage Suppressor (TVS) family of devices designed specifically to protect against electrical overstress (EOS) caused by electrostatic discharges (ESD). In today’s ever increasing demand for higher levels of performance and reliability, ESD protection must be included in most electronic systems. The MASMCJ11A provides reliable ESD protection using a multichannel I/O TVS diode array. The MASMCJ11A is an ideal solution for data line protection, providing fast, effective protection against ESD, electrical overvoltage and other transient voltage events.

The basic function of a TVS diode is to limit the voltage spike that results from an ESD event or other transient voltage event. The device works by “clamping” the voltage spike at a predetermined voltge, limiting the amount of damage or disruption to the connected equipment. The MASMCJ11A is designed to meet IEC 61000-4-2 requirements for ESD protection of up to 4kV contact discharge and 8kV air discharge. The diode is also designed to offer lightning protection with up to 15A peak pulse current. The diode is suitable for use in high-speed communication lines including RS-232, USB, Firewire, CAN bus, and Ethernet.

The MASMCJ11A is a low-profile diode with a very small outline size. The device features a wide operating temperature range (-55°C to +135°C), low leakage current, and high ESD withstand of up to 4kV. The diode is also fast-acting, providing fast, effective protection in as little as 10ns. The device is available in a variety of packages, including surface mount, through-hole, and VBGA.

The working principle of a TVS diode is based on the Zener diode concept. When voltage above a certain threshold is applied, the diode conducts, providing a path to ground for the excess electrical energy. When the reverse voltage is applied, the diode acts as a regular diode, blocking the flow of current. The MASMCJ11A also features an integrated TVS diode-Zener diode combination, which provides the dual function of ESD protection and overvoltage clamping.
