SMCJ78C-E3/57T

Transient voltage suppressors (TVSs) are solid state semiconductor devices specifically designed to provide a precise level of protection when large transient voltage surges are present on voltage or power supply lines. The SMCJ78C-E3/57T is a bi-directional TVS diode designed to protect electronic circuits and components from destructive spikes on a line. It provides both near instantaneous clamping and low clamping voltages combined with excellent protection for overvoltageage.

The SMCJ78C-E3/57T is suitable for a wide range of application fields, such as telecommunications, computers, industrial and automotive systems. This bi-directional TVS diode can also be used in board-level and induction systems. It also can be used for surge protection for data lines, I/O lines, and hotspots.

The working principle of the SMCJ78C-E3/57T is that it acts as a type of clamp in which it is able to limit voltage peaks near its breakover voltage. By doing this, it is able to protect the system from any additional voltage that exceeds its own breakdown voltage. Once this threshold is reached, the device then quickly and reliably switches from low impedance mode to high impedance mode. This provides an effective barrier against further voltage increases.

The SMCJ78C-E3/57T also has reverse polarity protection which prevents current from flowing back into the protected device. Reverse bias current is limited to a maximum value by an internal Zener diode that stops the diode from conducting in reverse.

The SMCJ78C-E3/57T is able to withstand very powerful transient voltage without being damaged. It is able to dissipate nominal power levels up to 8,000W on 10/1000 microseconds waveforms. This TVS diode is also able to withstand repetitive impulse discharges up to 6,000 waves with no malfunction or damage.

The SMCJ78C-E3/57T TVS diode is a compact and cost-effective solution for transient voltage surge protection. It is an efficient means of safeguarding electronic circuits, boards, and components from destructive voltage spikes.
