SMDJ43A R7G

The SMDJ43A R7G TVS - Diodes is an unidirectional device designed specifically for high-speed communication lines. It is composed of an integrated circuit, a Zener diode and a spark-gap diode, and is typically used for overvoltage protection. It operates by limiting the voltage applied across its terminals to a maximum value. This maximum level is referred to as the breakdown voltage.

When connected in series with the electrical line it is designed to protect, the SMDJ43A R7G will restrict the current that can flow in the line if the voltage exceeds the breakdown voltage. This protects the line from voltage surges which may cause damage or adversely affect performance. Even after a voltage surge, the SMDJ43A R7G will remember its initial operating state and reset once the voltage drops back below the breakdown voltage.

The SMDJ43A R7G TVS - Diode is generally used in automotive, industrial and consumer electronic applications. It is often applied to protect cameras, computers, LCD monitors, Ethernet and Automotive CANbus networks. It is also widely used in devices such as mobile phone chargers, power supplies, DC/DC converters and USB interfaces. The advantage of the SMDJ43A R7G is that it can be used in applications where a Zener diode alone might not be sufficient.

In terms of its working principle, the SMDJ43A R7G is a passive device that is triggered by a specific voltage. When the voltage exceeds the breakdown voltage of the device, the Zener diode will limit the current and the spark gap will begin to break down. This break down creates a low-resistance path that allows the current to be diverted away from the protected circuit and grounding. The excess current will be shunted to ground, thus protecting the circuit from overvoltage or electrostatic discharge.

The SMDJ43A R7G provides reliable protection and is suitable for a variety of applications. It features a low clamping voltage, low capacitance and low leakage current. Furthermore, it is RoHS compliant and has a high surge current capability.

In conclusion, the SMDJ43A R7G is a reliable and efficient TVS - Diode for protection against overvoltage. It is composed of an integrated circuit, a Zener diode and spark gap diode, and is widely used in automotive, industrial and consumer electronic applications.
