Application Field and Working Principle of SMC3K51CA-M3/9A TVS Diode

The SMC3K51CA-M3/9A TVS diode is a voltage-dependent, reverse conducting surveillace device specifically designed for ESD protection. This device is used to safeguard sensitive electronic circuits against excessive transient surges caused by Electro-Static Discharge (ESD).With a maximum stand-off voltage of 5.1V, the SMC3K51CA-M3/9A is capable of absorbing up to 40A peak pulse current for a duration of 10/1000ths of a second. Furthermore, its exceptional surge capability allows it to protect circuits from transients up to 11kV without failing. Its bidirectional feature makes the SMC3K51CA-M3/9A suitable for a variety of applications including consumer products, automotive, computers, communication equipment and military systems.The SMC3K51CA-M3/9A is rating for unidirectional and bidirectional applications. It works in two different ways; when an electro-static discharge (ESD) occurs it will act like a short circuit, allowing the current to pass through it and protecting the circuit from damage. When a surge is present, the diode will start conducting current and directing it away from the protected circuitry.At normal conditions, the diode is reverse biased and won’t conduct current. However, when a voltage higher than the specified reverse breakdown voltage is applied to the anode and cathode of the diode, it will start conducting current, allowing it to protect the circuit from overvoltage transients.The SMC3K51CA-M3/9A is an ideal choice for ESD protection applications. Its small body size, exceptional surge capability, cost effectiveness and bidirectional design has made it one of the most popular TVS diodes used today.
