10V rail protection in a DO-214AB SMC package
Its 10V reverse standoff voltage means the device does not conduct at normal operating voltage — it sits transparently across the rail until a surge pushes the line above the 11.1V minimum breakdown threshold. At that point the TVS clamps the voltage to 17V maximum while shunting up to 88.2A of peak pulse current in the standard 10/1000µs waveform, absorbing 1500W of peak pulse power.
The DO-214AB (SMC) package is a surface-mount footprint with a large copper tab for heat sinking; the board layout should connect the cathode tab to the protected rail with a low-inductance trace and place the TVS close to the connector or transient entry point.
