3.0SMCJ16ATR Circuit Protection

Transient voltage suppression (TVS) diodes are becoming increasingly popular in sensitive electronics and electrical circuits. TVS diodes offer greater protection than metal oxide varistors (MOVs) due to their ability to suppress and clamp fast transients. 3.0SMCJ16ATR is an example of TVS Diode. This device is designed to provide overvoltage transients with a high level of protection across a wide range of applications.

3.0SMCJ16ATR TVS diode is suitable for transient voltage suppression in industrial, commercial and automotive applications. It offers a low maximum leakage current and high peak surge current capability of 300A (tp=8.3ms). This device is RoHS compliant, making it environmentally friendly. It also provides a wide operating temperature range of -55°C to 150°C.

The 3.0SMCJ16ATR diode is designed to protect low voltage data lines from voltage surges, lightning strikes, and electrostatic discharge (ESD). This device can also be used to protect low voltage equipment from electrical transients caused by nearby switching events, such as contactors and relays. It is ideal for high speed logic and low voltage microcontrollers, providing reliable protection in automotive and industrial electronic systems.

The working principle of the 3.0SMCJ16ATR diode is based on a combination of Zener and avalanche breakdown characteristics. When a transient voltage is applied, the Zener part of the diode starts to conduct. The voltage reaches a critical level where the avalanche breakdown starts and the majority of the transient current is forced to flow through the device. This allows the device to clamp the voltage of the transient to a safe level, preventing damage to the surrounding circuitry.

The 3.0SMCJ16ATR is a popular choice for TVS diode applications. This device offers an ideal balance between performance and cost, making it suitable for a wide range of applications. The combination of its low leakage current, high peak current capability, and wide operating temperature range makes it an excellent choice for protection against transient voltage surges.
