Applications
The SM6F36AY is designed to protect automotive electronic control units and body electronics operating on 24 V or 36 V bus architectures against load dump transients and ESD events. Its 600 W peak pulse power rating and 76 V clamping voltage make it suitable for protecting MOSFET gate drivers, LIN transceivers, and CAN bus interfaces in harsh automotive environments. 48 V mild hybrid vehicle power nets and industrial power supplies with similar voltage ratings also benefit from its fast transient response.

Frequently Asked Questions
What is the peak pulse power rating of SM6F36AY and how does it handle automotive load dump events?
The SM6F36AY is rated for 600 W peak pulse power at 10 ms pulse width, which covers the ISO 7637-2 load dump transients typical on 24 V commercial vehicle systems. During a load dump event, the device clamps the line voltage to a maximum of 76 V within nanoseconds, protecting downstream ICs from damage caused by overvoltages up to 200 V on the bus.
For a 24 V truck body electronics module, what margin does SM6F36AY provide between the standoff and clamping voltages?
The SM6F36AY has a 36 V working peak inverse voltage standoff and a maximum clamping voltage of 76 V at the 600 W pulse current. This 40 V margin ensures the TVS remains non-conducting during normal 24 V bus operation while activating quickly on transients. The breakdown voltage range of 40 V to 44.2 V provides precise triggering without false clamping.
How does the SOD128 Flat package of SM6F36AY compare to DO-218 when optimising automotive PCB layouts?
The SOD128 Flat (also known as SOD-128 or PowerSOD-128) package measures approximately 3.8 mm x 2.6 mm with a flat profile under 1.1 mm, compared to the taller DO-218 which can reach 2.2 mm height. The lower profile suits modern automotive ECU boards with conformal coating requirements, and the 2-pad layout allows automated reflow soldering at peak reflow temperatures up to 260 degrees C.
What is the lead time for SM6F36AY and how should automotive tier-1 suppliers plan procurement?
STMicroelectronics lists a 25-week factory lead time for SM6F36AY, which is longer than typical passive components. Automotive tier-1 suppliers should include this part in long-horizon MRP planning and carry at least 12 to 16 weeks of safety stock to buffer against supply variability. Blanket orders placed with authorised distributors can reduce effective lead time risk for high-volume programmes.
