Key Features
- 600 W peak pulse power dissipation capability for robust transient suppression on 12 V automotive lines
- 27.2 V maximum clamping voltage with 15.2 V nominal breakdown providing tight overvoltage protection
- Automotive-grade SOD128 Flat surface-mount package with unidirectional silicon TVS for PCB-level protection
Applications
SM6F13AY provides transient voltage protection on 12 V automotive power lines, shielding ECUs, body control modules, and sensor interfaces from load dump and inductive switching spikes up to 600 W peak. Its 27.2 V clamping voltage protects downstream ICs rated for 20 V to 26 V absolute maximum on automotive 12 V battery rails during transient events. The SOD128 Flat package enables high-density placement near protected pins on compact automotive PCBs.

Frequently Asked Questions
What peak pulse power can SM6F13AY clamp and over what pulse duration?
SM6F13AY handles 600 W of peak pulse power, typically specified for a 10/1000 µs waveform per automotive transient test standards. During a load dump event on a 12 V automotive battery line, this 600 W capability absorbs the energy spike before the clamping voltage rises above the 27.2 V maximum, protecting downstream electronics rated below 30 V.
How do the breakdown voltage limits of SM6F13AY affect selection for a 12 V automotive rail?
SM6F13AY has a nominal breakdown voltage of 15.2 V with a minimum of 14.4 V and a maximum of 16 V. This range ensures the device remains non-conducting under normal 12 V to 13.8 V battery charging conditions but begins clamping when transients exceed 14.4 V, preventing the voltage from rising above the 27.2 V maximum clamp level that could damage 5 V or 3.3 V interface circuits.
When should SM6F13AY be chosen over a bidirectional TVS on an automotive signal line?
A unidirectional TVS like SM6F13AY is the correct choice for DC power rails and unipolar signal lines where transients always appear as positive overvoltage relative to ground. Bidirectional TVS devices are needed only on AC or bipolar lines such as CAN bus or LIN bus differential pairs. Choosing SM6F13AY on a unipolar 12 V rail lowers the forward voltage drop in the conducting direction, improving clamping speed and reducing clamped energy compared to a bidirectional device of the same 600 W rating.
