The P6SMBJ400A from Littelfuse is a unidirectional transient voltage suppression (TVS) diode designed to protect sensitive electronic circuits from voltage transients. It features a reverse standoff voltage of 342V and a maximum clamping voltage of 548V at a peak pulse current of 1.1A. With a peak pulse power rating of 600W (10/1000μs waveform), this device provides robust protection for general purpose applications.
This TVS diode is not intended for power line protection, as indicated by the specification. It operates over a wide temperature range from -55°C to 150°C, making it suitable for demanding environments. The component is mounted using surface mount technology and comes in a compact DO-214AA (SMB) package, which is also known as SMBJ package format.
The unidirectional design (1 channel) ensures fast response to positive transients. While specific breakdown voltage and reverse leakage current are not provided in the available data, the key clamping and standoff parameters allow engineers to integrate this part into overvoltage protection circuits requiring a 342V threshold.
