TVS - Diodes are an integral part of modern electronics and have a wide range of uses. The 3.0SMCJ90ATR is one such device used in many applications across multiple industries. This TVS diode is designed to offer protection against transient voltage surges and ESD (electrostatic discharge). This article will discuss the application field of the 3.0SMCJ90ATR and its working principle.

The 3.0SMCJ90ATR is a unidirectional TVS diode that is designed to offer protection against voltage surges and ESDs. It can handle ratings up to 9kV and is suitable for use in a wide range of applications. This device is ideal for use in automotive, consumer electronics, industrial and telecommunications applications. It is also often used in power supply and energy distribution systems. This device is available in various packages including surface mount and through-hole.

The 3.0SMCJ90ATR offers protection from overvoltage surges, ESDs and other similar transient events. It is designed to clamp or divert unwanted surge currents away from delicate electronic circuits. The device has a breakdown voltage of 9kV and a peak pulse current of 90A. The device also has a low leakage current and a low capacitance. The maximum reverse clamping voltage of the device is 35V.

The working principle of the 3.0SMCJ90ATR is relatively simple. When a voltage above the breakdown voltage, or BV, is applied, the diode begins to conduct current. The current flows from the anode to the cathode and the voltage is “clamped” at a certain point. This clamping voltage is usually lower than the breakdown voltage. This prevents damage to sensitive electronic components by limiting the voltage that reaches them.

The 3.0SMCJ90ATR is suitable for use in a wide range of applications. Most notably, its protection features make it a popular choice in automotive and energy distribution systems. It can also be used in power supplies, consumer electronics and telecommunications applications. Its capacity for handling high current pulses and its low leakage current make it an ideal choice for these types of applications.

In summary, the 3.0SMCJ90ATR is a unidirectional TVS diode that offers protection against voltage surges and ESDs. It has a breakdown voltage of 9kV and a peak pulse current of 90A. It is suitable for use in automotive, consumer electronics, industrial and telecommunications applications. Its working principle is relatively simple; when the breakdown voltage is exceeded, the diode begins to conduct current, clamping the voltage at a certain point and preventing damage to sensitive components.
