For a 24V rail, this TVS is overkill — the 43V standoff is well above the rail, so the part never conducts during normal operation. It would only clamp on a transient that exceeds 47.8V, which is plausible on a 24V bus with inductive kickback or surge events.","metaTitle":"SMAJ43CE3/TR13 – Microchip 43V Zener TVS, 500W, DO-214AC","metaDescription":"Microchip SMAJ43CE3/TR13 Zener TVS diode: 43V reverse standoff, 500W peak pulse power, bidirectional, DO-214AC (SMA).
