SMCJ188CA-TR TVS Diode by STMicroelectronics

The SMCJ188CA-TR is a robust transient voltage suppressor (TVS) diode designed by STMicroelectronics, a global semiconductor leader known for its innovative and reliable components. This TVS diode is specifically engineered to protect sensitive electronic equipment from voltage transients induced by system-induced voltage spikes or other transient voltage events such as lightning, electrostatic discharge (ESD), and load switchovers.

With its bidirectional clamping feature, the SMCJ188CA-TR is ideal for AC line protection or instances where a reverse voltage condition may occur. It is housed in a low-profile SMC package, which is highly valued for its compact footprint and its ability to handle high surge power dissipation. The device is rated at 1500W peak pulse power capability for a 10/1000μs waveform, which is sufficient to safeguard most circuits from even the most severe transient threats.

The clamping voltage of the SMCJ188CA-TR is meticulously designed to activate just above the normal operating voltage of most electronics, ensuring that the diode remains non-conductive during regular operation, and only responds when a potentially damaging voltage spike occurs. This diode has a stand-off voltage of 188V, which is the maximum voltage that the device can withstand without going into avalanche breakdown, providing a wide margin of safety for a variety of applications.

One of the key benefits of the SMCJ188CA-TR is its fast response time to transient events, typically in the picosecond range, which is crucial for protecting modern high-speed electronic circuits. Additionally, the device meets the ISO 7637-2 standard for pulse 5 protection and is compliant with the IEC 61000-4-2 and IEC 61000-4-5 surge immunity standards, making it a reliable choice for automotive and industrial applications where adherence to regulatory standards is a must.

STMicroelectronics has designed the SMCJ188CA-TR with longevity and reliability in mind, ensuring that it can withstand multiple high-energy pulses without degradation. Its robust construction and adherence to high-quality standards make it an excellent choice for designers looking to increase the durability and reliability of their electronic systems.

Whether you are designing power supplies, automotive electronics, or industrial control systems, the SMCJ188CA-TR from STMicroelectronics provides the protection your circuits need against the unpredictable nature of transient voltage events.
