The SMCJ85CA is a TVS diode designed specifically for transient voltage suppression applications. TVS diodes, also known as Transient Voltage Suppressors (TVSs), are components used to protect circuits and devices from transient high-voltage spikes. They do this by diverting excessive current that has been induced in the circuit, either by environmental factors such as lightning, or by electromagnetic interference from motors or other power sources. The SMCJ85CA is rated to withstand up to 8.5 V peak to peak and is able to absorb ESD pulses of up to 25 kV in magnitude.
When an excessive transient voltage is encountered, the SMCJ85CA diode will begin to conduct current, and its cathode will become more positive than its anode. This will cause the diode to enter its forward conduction mode, which will protect the other components of the circuit. As the current is diverted away from the other components, the voltage in the circuit is adjusted to a safe level. Once the voltage returns to its normal level, the diode will stop conducting current and its cathode will become negative with respect to its anode, thus turning it off. This simple on/off switch action is the working principle of a TVS.
Since TVS diodes are designed to handle transient voltages, they are commonly used in sensitive electronic applications such as automotive, computers, telecommunications, and medical equipment. The SMCJ85CA is specifically designed to be used in AC applications with frequencies up to 100 MHz and can be used in any application that requires transient voltage protection. It is certified to meet international safety standards and is rated for operation in temperatures ranging from -65°C to + 155°C. This makes it ideal for automotive applications that must endure wide temperature ranges.
TVS diodes, such as the SMCJ85CA, provide a reliable and cost-effective solution for protecting sensitive electronic circuits from transient surges. They are reliable, efficient, and require minimal external components to maintain their performance. With its wide temperature range and ability to withstand frequencies up to 100 MHz, the SMCJ85CA is an ideal choice for a variety of applications that require transient voltage protection.
