SZP6SMB33CAT3G Description

Short technical summary and product information.

The SZP6SMB33CAT3G is a bidirectional Zener TVS diode from Littelfuse, part of the SZP6SMB series. It provides 600W peak pulse power (1ms) for protecting voltage sensitive components from high voltage transients. Key electrical characteristics include a reverse standoff voltage of 28.2V, nominal breakdown voltage of 33V, and maximum clamping voltage of 45.7V at 13.2A peak pulse current (10/1000µs waveform).

 

Response time is typically less than 1 ns, and leakage current is below 5 µA above 10V. The device offers ESD protection in accordance with IEC 61000-4-2 (30 kV air/contact) and Class 3 HBM rating (>16 kV). It is AEC-Q101 qualified and PPAP capable, making it suitable for automotive electronic applications.

 

The SZP6SMB33CAT3G is supplied in a cost-effective DO-214AA (SMB) surface mount package. Operating junction temperature range is -65°C to 150°C. The SZ prefix indicates automotive grade with unique site and control change requirements.
