Transient Voltage Suppressors (TVS), also known as Transient Voltage Surge Suppressors or Transient Voltage Clamp Diodes, is a device used to protect circuits from damaging voltage transients, which occur during power-up or power-down sequences. The SMCJ70A V7G is an advanced TVS diode designed to protect sensitive equipment in industrial and communications applications from high-voltage transients and power surges.

The SMCJ70A V7G is specifically designed to offer superior protection against electrostatic discharge (ESD), electrical fast transients (EFT), and voltage surges at the board level. The device is capable of dissipating high power and features a low clamping voltage that is ideal for space-sensitive industrial and computer/telecom applications. The diode provides 400W of peak pulse power dissipation, with a nominal breakdown voltage of 70V and a maximum clamping voltage of 95V.

The SMCJ70A V7G is specifically designed with reverse biased avalanche breakdown technology to safely dissipate high-voltage transients and power surges. The diode also features a high reverse blocking voltage of 800V. During signal propagation, the diode provides an extremely low signal degradation with a typical maximum capacitance of just 2pF and a maximum leakage current of 25µA.

The SMCJ70A V7G is ideal for many industrial and communications applications. The device can be used in data processing and telecommunications systems, computer peripherals, 120VAC power supplies, and process control systems. The diode provides superior line-to-ground and line-to-line protection, and is also an excellent choice for protecting against electrostatic discharge, lightning strikes, and other overvoltage transients.

The SMCJ70A V7G offers superior protection against spikes, surges, and ripples transmitted through power circuits. The diode is essentially an equivalent of an overvoltage or surge protector that works by clamping excessive voltages when they exceed a certain threshold. When a voltage surge is detected, the device activates and acts as a low-impedance short circuit, diverting the current away from the device being protected. The diode also offers fast response times of up to 40V/ns, ensuring that the circuit is protected in the event of an overvoltage condition.

The SMCJ70A V7G is an ideal choice for applications requiring superior overvoltage protection. The device is easy to install and offers excellent levels of protection, making it an excellent choice for industrial and communications applications. The diode provides 400W of peak power dissipation, with a nominal breakdown voltage of 70V and a maximum clamping voltage of 95V, making it an ideal choice for protecting sensitive equipment from high-voltage transients and power surges.
