Frequently Asked Questions
How much peak pulse power can SM6F5.0AY clamp, and what breakdown voltage range does it guarantee?
SM6F5.0AY handles 600 W peak pulse power with a guaranteed breakdown voltage between 6.4 V and 7.1 V, clamping transients to a maximum of 13.4 V. This makes it well-suited for protecting 5 V microcontroller I/O lines and bus interface circuits against ESD and ISO 7637 automotive load dump pulses.
Is SM6F5.0AY qualified for automotive applications, and which bus lines does it protect?
Yes, SM6F5.0AY is automotive-qualified and designed to protect 5 V signal lines such as CAN bus, LIN bus, and sensor supply rails in vehicles. Its unidirectional configuration and 5 V standoff voltage prevent false clamping under normal operating conditions while immediately diverting surge currents above the 6.4 V minimum breakdown threshold.
How does the SOD128 Flat package of SM6F5.0AY compare to larger DO-214 TVS packages for PCB space savings?
The SOD128 Flat package has a footprint of approximately 3.8 mm × 2.6 mm, significantly smaller than the DO-214AB (SMC) package at 7.5 mm × 5.3 mm, allowing designers to place protection devices within 2 mm to 5 mm of connector pads in compact automotive ECU and industrial I/O boards without consuming excessive routing area.
