Frequently Asked Questions

What peak pulse power and standoff voltage does SM6F11AY provide for automotive ESD protection?

The SM6F11AY handles 600 W peak pulse power based on a 10/1000 µs waveform with an 11 V standoff voltage. Its breakdown voltage ranges from 12.3 V minimum to 13.7 V maximum, and the maximum clamping voltage is 24.2 V at peak pulse current, making it ideal for protecting 12 V automotive rail components from voltage transients.

How does the SOD128 Flat package of SM6F11AY contribute to board space savings in an automotive ECU?

The SOD128 Flat package measures approximately 3.8 mm x 2.6 mm, which is roughly 30% smaller than the standard DO-218AB package while delivering the same 600 W peak pulse power. This compact 2-pin SMD footprint allows placement directly adjacent to protected ICs on dense automotive PCBs, minimizing parasitic inductance in ESD protection loops.

For an automotive sensor input protection design, why choose SM6F11AY over a lower-power 400 W TVS diode on a 12 V rail?

The SM6F11AY's 600 W peak pulse power rating provides a 50% higher surge margin compared to 400 W alternatives, covering ISO 7637-2 pulse categories up to 600 W on 12 V automotive loads. Its clamping voltage of 24.2 V maximum keeps protected IC inputs within safe limits, and AEC-Q101 automotive qualification ensures reliability over -40°C to +150°C junction temperature ranges.
