Product details

600W automotive TVS in a standard SMB footprint

It protects a single line with a 64.1V reverse standoff voltage and clamps transients to 134V maximum at the peak pulse current.

Clamping voltage and pulse current — sizing the protection

The 134V clamping voltage at the 30A (8/20µs waveform) peak pulse current sets the upper limit the protected circuitry must survive. For a 12V automotive rail, the 64.1V standoff gives enough headroom above normal battery voltage including load dump transients.

AEC-Q101 and the automotive supply chain

The active lifecycle status confirms STMicroelectronics continues to manufacture the SM6T75AY with no end-of-life notice.

Frequently asked questions

What is the peak pulse power of SM6T75AY?

The SM6T75AY is rated for 600W peak pulse power, measured with a 10/1000µs waveform. This is the energy-handling capacity for a single transient event.

Is SM6T75AY AEC-Q101 qualified?

Yes, the SM6T75AY carries AEC-Q101 qualification, making it suitable for automotive-grade electronic modules and systems.
