400W bidirectional TVS in a DO-214AC footprint
The SMAJ110CA-13-F: The 177V clamping voltage at 2.3A peak pulse current means this part clamps a 110V nominal rail hard enough to protect downstream silicon from transients up to that energy level. Packaged in a DO-214AC (SMA) footprint with a supplier device package of SMA, this surface-mount diode suits standard reflow assembly.
Clamping and breakdown voltages that define the protection window
The reverse standoff voltage is 110V — the nominal rail voltage below which the diode draws negligible leakage. Breakdown occurs at a minimum of 122V, and the clamping voltage maxes at 177V when the 2.3A peak pulse current flows. This 55V window between standoff and clamp gives the designer margin for transient energy absorption without nuisance triggering on normal line ripple. Power line protection is marked as 'No', meaning this device is not intended for direct AC mains surge suppression — it targets DC rails and signal lines where bidirectional clamping is needed.
