Its 78V reverse standoff voltage means the part does not conduct leakage until the line exceeds 78V. The 500W peak pulse power rating gives you the energy margin to survive a surge event without the part failing short.
Sourced per RFQ against your BOM quantity — no stock-holding claim, but the active status keeps the supply chain open through standard distribution.
The SMAJ78CAE3/TR13 is rated for 500W peak pulse power under a 10/1000 µs waveform. That 500W rating is typical for the DO-214AC package size; it sets the maximum energy the part can absorb in a single surge event before the junction temperature exceeds 150°C.
It is a bidirectional Zener TVS. One device clamps both polarities, so you can use it on AC signal lines or bipolar supplies without adding a series diode. The breakdown voltage is 86.7V min in both directions.
