SMCJ85ATR

Transient voltage suppression (TVS) diodes are widely used in electronics today. They are designed to protect against voltage spikes and transients, by providing a fast, low impedance path to ground. The SMCJ85ATR is a surface mountable, unidirectional TVS diode from Vishay Intertechnology. This type of TVS diode is designed for use in protecting sensitive electronics from surges up to 5.5kV, such as from lightning or other power line surges. It is suitable for use in both consumer and industrial applications.

The SMCJ85ATR offers high surge capability and fast response times, as well as low leakage current and low clamping voltage during normal operating conditions. It is designed in a J-bend, ultra-small, SOD-323 package with a footprint of 0.84mm². This diode also has a wide operating temperature range of -55 to +175°C and is suitable for flow and reflow soldering processes.

The working principle of the SMCJ85ATR is quite simple. When a voltage surge enters the diode, it immediately begins to conduct, creating a fast, low impedance path for the transient energy to be discharged. This helps to protect the sensitive electronic components that are connected to it. As the voltage drop decreases, the diode will recover and stop conducting.

The SMCJ85ATR has a wide variety of applications, such as providing overvoltage protection to computers, personal electronics, automotive systems, and power supplies. It is also used in cell phones, circuit boards, consumer appliances, and LCD displays. In addition, this diode can be used in both consumer and industrial applications, as it is designed to operate in temperatures up to 175°C. The SMCJ85ATR is also designed for use in AC and DC circuits.

In summary, the SMCJ85ATR is a unidirectional TVS diode that is designed for a wide range of applications. It offers high surge capability and fast response times, while also having low leakage current and low clamping voltage during normal operating conditions. This diode has a wide operating temperature range and is suitable for flow and reflow soldering processes. Its working principle is quite simple and it is designed to provide protection against voltage spikes and transients.
