STMicroelectronics SMA6J20CA-TR Transient Voltage Suppressor

The SMA6J20CA-TR from STMicroelectronics is a robust Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This high-performance device is housed in a compact SMA (DO-214AC) package, making it suitable for surface mount technology (SMT) and ideal for high-density circuit boards where space is at a premium.

The SMA6J20CA-TR is specifically engineered to provide bidirectional clamping protection, with a standoff voltage of 20V, ensuring that both positive and negative voltage spikes are safely managed. This TVS diode is characterized by its fast response time to transient events, typically in the picosecond range, which is critical for protecting modern electronic circuits that are sensitive to rapid voltage changes.

Featuring a peak pulse power dissipation of 600W (10/1000μs waveform), the SMA6J20CA-TR is capable of handling significant energy associated with surge events without compromising the integrity of the protected component. Its low incremental surge resistance helps in reducing the clamping voltage during the surge event, thus offering enhanced protection for sensitive components.

Additionally, the SMA6J20CA-TR boasts a low leakage current, which is beneficial for power conservation in battery-powered devices, and it also meets the ISO 7637-2 pulse 5a and 5b standard, making it suitable for automotive applications. Furthermore, it complies with IEC 61000-4-2 and IEC 61000-4-5 surge immunity standards, which are essential for electronic devices that must operate reliably in environments with electrical noise and potential surges.

With its excellent clamping capability, fast response time, and high surge capability, the SMA6J20CA-TR is an excellent choice for protecting voltage-sensitive components in a variety of applications, including automotive systems, industrial electronics, computer interfaces, and telecom equipment.

For designers and engineers looking for a reliable and space-efficient solution to protect their circuits from voltage transients, the SMA6J20CA-TR from STMicroelectronics offers a perfect blend of performance, durability, and compactness.
