SM6T33CAY Description

Short technical summary and product information.

The SM6T33CAY is a bidirectional Zener TVS diode designed for automotive applications. It features a reverse standoff voltage of 28.2V typical and a maximum clamping voltage of 59V at 68A peak pulse current (8/20µs waveform). With a peak pulse power rating of 600W, this device provides robust transient voltage suppression for sensitive electronics.

 

This component is surface mount packaged in a DO-214AA (SMB) case, suitable for automated assembly. It operates over a wide temperature range of -55°C to 150°C, making it reliable in harsh automotive environments. The part is not intended for power line protection, focusing instead on signal and data line protection.

 

As an automotive-grade component, the SM6T33CAY meets the reliability and performance requirements of vehicle electronic systems. Its bidirectional configuration allows protection of circuits where the signal can swing both positive and negative relative to ground.
