SMCJ26CA-TR Transient Voltage Suppressor by STMicroelectronics

The SMCJ26CA-TR from STMicroelectronics is a robust Transient Voltage Suppressor (TVS) designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is a bidirectional device housed in a DO-214AB (SMC) package, which is well-suited for surface mount applications.

With its stand-off voltage of 26V, the SMCJ26CA-TR is engineered to stabilize overvoltage spikes and prevent them from damaging connected components. It is particularly effective in safeguarding systems that are exposed to high energy transients. The device is characterized by its high surge capability, which enables it to handle high transient power dissipation, making it an ideal choice for a broad range of applications.

The SMCJ26CA-TR features a peak pulse power dissipation of 1500 Watts (at 10/1000μs waveform), which ensures a high level of protection for sensitive circuits. Its response time is virtually instantaneous, less than 1.0 picosecond from 0V to BV min, providing immediate protection against transient overvoltage events. This rapid response time is critical for modern high-speed electronics where even microsecond delays can cause significant damage.

Designed to meet the IEC 61000-4-2 and IEC 61000-4-5 standards, the SMCJ26CA-TR offers reliable performance under harsh conditions. It is compliant with RoHS and Halogen-Free requirements, making it suitable for use in environmentally sensitive applications. Additionally, it supports a wide operating junction temperature range from -55°C to +150°C, which ensures stability and functionality across various temperature environments.

The low clamping voltage of the SMCJ26CA-TR minimizes stress on the protected component during a transient event, while its low leakage current helps in maintaining energy efficiency in the system. Its bidirectional nature means that it provides symmetrical protection in AC circuits or where the polarity of the transients is unpredictable.

In summary, the SMCJ26CA-TR by STMicroelectronics is a high-quality TVS diode that offers excellent transient voltage suppression capabilities, making it an essential component for protecting sensitive electronics in a variety of applications.
