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.","metaTitle":"SMAJ78CAE3/TR13 TVS Diode – 78V Standoff, 500W","metaDescription":"SMAJ78CAE3/TR13 from Microchip Technology: 78V reverse standoff, 500W peak pulse power, bidirectional Zener TVS in DO-214AC (SMA).

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."},{"question":"Is SMAJ78CAE3/TR13 unidirectional or bidirectional?","answer":"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.
