The bidirectional design means a single device handles both positive and negative transients, simplifying layout on AC-coupled or bipolar rails. The 151V clamping voltage at 3.3A (10/1000µs) is the ceiling the protected circuit must survive. If your downstream components are rated below 151V, the SMAJ85CE3/TR13 will not protect them — you need a lower-voltage clamp or a higher-energy device. The 500W peak pulse power is the energy rating for a single 10/1000µs pulse; for repetitive surges or longer pulse widths, derate per the datasheet curve. ## Active production – sourcing through distribution","metaTitle":"SMAJ85CE3/TR13 TVS Diode – Microchip, 500W, Bidirectional","metaDescription":"Microchip SMAJ85CE3/TR13 Zener TVS diode: 500W peak pulse power, 85V standoff, 151V clamping, bidirectional, DO-214AC.
