That clamping ceiling is what the downstream silicon sees — keep it below the absolute maximum rating of the protected IC. ## Package and temperature grade — board-fit and environment check","metaTitle":"SMAJ85CAE3/TR13 – Microchip 85V Bidirectional TVS, DO-214AC","metaDescription":"SMAJ85CAE3/TR13 Zener TVS diode, 85V reverse standoff, 137V clamp, 3.6A peak pulse, DO-214AC SMA, active production.
