SMCJ33CA-TR/N Transient Voltage Suppressor from STMicroelectronics

The SMCJ33CA-TR/N 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 TVS diode is a bidirectional device, meaning it can provide protection in both forward and reverse directions, making it an ideal choice for AC applications or where the polarity is uncertain.

Key Features

• Stand-off Voltage: The SMCJ33CA-TR/N has a stand-off voltage of 33V, which is the maximum voltage that the diode can withstand without conducting significant current.
• Peak Pulse Power: It offers a peak pulse power dissipation of 1500 Watts for 10/1000μs waveform, ensuring reliable protection against high energy transients.
• Clamping Voltage: The device has a clamping voltage of 53.3V, which is the maximum voltage to which it will limit the transient when subjected to a surge event.
• Package: Housed in a SMC (DO-214AB) package, the SMCJ33CA-TR/N is compact and suitable for high-density circuit board designs.
• Low Leakage Current: It features a low leakage current, minimizing power loss when the device is in standby mode and enhancing system efficiency.
• Fast Response Time: The TVS diode provides a fast response time to transient events, typically in the picosecond range, ensuring immediate protection for sensitive components.
• RoHS Compliant: This product is RoHS compliant, meeting the European Union's directives on the restriction of hazardous substances in electronic equipment.
