The SMCJ33CA-TR is a robust transient voltage suppression (TVS) diode designed by STMicroelectronics, a leader in the semiconductor industry. This component is specifically engineered to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 33V, making it suitable for a range of applications that require this level of protection.
• Peak Pulse Power: It can handle a peak pulse power of 1500W (10/1000μs), providing a high level of protection against energy transients.
• Clamping Voltage: The SMCJ33CA-TR has a clamping voltage of 53.3V, ensuring that any transient above this threshold is effectively clamped down to a safer level.
• Bi-directional Protection: As a bi-directional TVS, it can protect circuits from surges occurring in both directions along the signal or power line.
• Low Leakage Current: It features a low leakage current, minimizing power loss when the device is in standby mode and enhancing the overall efficiency of the application it is used in.
• Response Time: With a response time typically less than 1 picosecond from 0V to BV min, it provides immediate protection upon detection of a voltage spike.
• Package: The SMCJ33CA-TR is available in a surface-mount SMC package, which is suitable for high-density PCB designs and is compatible with automated assembly processes.

Applications

The SMCJ33CA-TR is ideal for protecting voltage-sensitive components in a variety of applications, including:
