A 17V rail sees no leakage at steady state; the TVS only begins conducting when the transient pushes the line above 18.9V. The clamping voltage of 30.5V is the worst-case ceiling at 16.4A peak current. If the downstream IC has an absolute-max rating below 30.5V, you need a lower-clamp part or additional series impedance. For shorter pulses (e.g. 8/20µs from ESD), the part can absorb significantly more peak current; the datasheet derating curve should be consulted for non-standard waveforms. Surface-mount DO-214AC (SMA) package. No power-line protection feature — this is a signal- or low-power-rail protector, not a mains-side suppressor.

It clamps both positive and negative transients symmetrically, so it works on AC signals or bipolar rails without needing two diodes back-to-back."},{"question":"What is the closest pin-compatible alternative in the same family?","answer":"Within the SMAJ series, the unidirectional variant (e.g. SMAJ17A) shares the same DO-214AC footprint and standoff voltage but clamps only one polarity. For a bidirectional part, the SMAJ17CA is the standard commercial-grade sibling. The '' suffix on this Microchip part indicates a tin-lead (Pb-free) finish; the standard suffix may differ.
