Transient Voltage Suppressor (TVS) diodes are an integral component in modern power management applications. They are used to protect against voltage spikes, that can damage sensitive circuitry in an electronic system. The SMCJ10CA-M3/57T TVS diode is an ultra-low capacitance, high-power diode designed for high performance protection from transients in sensitive components.

The SMCJ10CA-M3/57T has an operating voltage of 350V, meaning that it is suitable for protecting components that use AC mains power and other higher voltage supplies. It has a maximum stand-off voltage of 175V and a typical clamping voltage of 157V. This diode can handle a maximum surge current up to 2,200A and a maximum capacitance of just 0.31pF.

The SMCJ10CA-M3/57T is a bi-directional diode, meaning that it can protect a circuit from high power, transient voltages from either polarity. The diode has an extremely low forward voltage, with only 5V maximum, and is able to clamp transient voltages to the clamping voltage very quickly, typically within a few nanoseconds.

The SMCJ10CA-M3/57T is well suited to use in AC mains powered circuits, with a variety of applications. These include AC/DC converters, uninterruptible power supplies (UPS), DC/DC converters, power supplies, telecommunications systems, industrial relays and controllers, portable equipment, audio/visual equipment, automotive systems and medical equipment.

The principle of operation of the SMCJ10CA-M3/57T is relatively simple. In moments when the voltage spike exceeds the maximum stand-off voltage of the diode, the diode will become forward biased, and current will flow through it. The current through the device reduces the voltage, as it passes through the diode and associated circuitry, and the voltage is clamped to the maximum clamping voltage of the device. Once the transient voltage passes or is reduced below the maximum standoff voltage, the diode will switch off and the voltage across it is reduced to a low level.

This is an effective method of limiting the voltage, and reducing the effect the transient voltage can have on the sensitive components in the circuit. The SMCJ10CA-M3/57T is also well suited to high power applications, with a high current rating and low capacitance.

The SMCJ10CA-M3/57T is an ideal solution for protecting high power and sensitive components from overvoltage surges, availing in a range of applications. The bi-directional operation, ultra-low capacitance and fast clamping make it one of the most versatile and reliable transients suppressors.
