1500W bidirectional TVS in a DO-13 can
The 1N6066A/TR: The single bidirectional channel protects against both positive and negative transients, making it suitable for AC power lines, bipolar DC rails, or signal lines where polarity is not fixed.
Breakdown voltage and clamping margin
With a reverse standoff voltage of 110V, the diode begins conducting above that level; the 124V minimum breakdown ensures the device does not avalanche below the rail's normal operating peak. The 182V maximum clamping voltage at 8.2A peak pulse current defines the worst-case voltage the protected circuit sees during a surge — a 58V window between standoff and clamp gives margin for downstream component voltage ratings.
