The SMAJ33A-TR is a unidirectional TVS (Transient Voltage Suppressor) diode from STMicroelectronics designed to protect sensitive electronic circuits from overvoltage transients. It features a reverse standoff voltage of 33 V and a maximum clamping voltage of 69.7 V when subjected to a 33 A peak pulse current (8/20 µs waveform). With a peak pulse power rating of 400 W, it is suitable for general purpose circuit protection applications.
The device utilizes a Zener technology structure and provides protection for a single channel with unidirectional polarity. It is designed for surface mount assembly and is offered in the compact DO-214AC (SMA) package. The operating temperature range spans from -55°C to 150°C, allowing operation in a wide range of environments. The component does not include power line protection and is intended for general purpose use.
The SMAJ33A-TR is compliant with RoHS3 regulations and has a Moisture Sensitivity Level (MSL) rating of 1 (unlimited). It is also classified as unaffected under REACH. These attributes, combined with its electrical specifications, make it a viable choice for overvoltage protection in consumer, industrial, and communication equipment.
