About this product
A bidirectional 400 W TVS (transient voltage suppression) diode in the SMA (DO-214AC) package, with a 16 V standoff voltage. It protects I/O lines, power buses and sensitive circuits from transient overvoltage and ESD events.

Frequently asked questions
What does the CA suffix mean?
CA indicates a bidirectional device that clamps both positive and negative transients. It suits AC lines and signal lines that swing both ways.
How do I choose the standoff voltage?
The standoff voltage (16 V here) should be above the normal operating voltage of the line, so the TVS stays inactive during normal operation. Check the clamping voltage in the datasheet.
