SMCJ40CA-TR Description

Short technical summary and product information.

The SMCJ40CA-TR is a bidirectional Zener TVS diode from STMicroelectronics designed for general-purpose transient voltage suppression. It features a reverse standoff voltage of 40V and a clamping voltage of 84V, providing robust protection against voltage spikes. The device can handle a peak pulse current of 119A (8/20µs waveform) and a peak pulse power of 1500W (1.5kW).

 

This TVS diode is mounted using surface-mount technology in a DO-214AB (SMC) package, making it suitable for automated assembly processes. It operates over a wide temperature range from -55°C to 150°C, ensuring reliability in harsh environments. The bidirectional configuration allows it to protect circuits from both positive and negative transients.

 

Typical applications include general-purpose circuit protection in consumer electronics, industrial equipment, and communication systems. The device is RoHS3 compliant and has an MSL of 1 (unlimited), simplifying handling and storage requirements.
