The breakdown voltage starts at 36.7V minimum, so the device stays out of the circuit until a real surge arrives. ## Active production, standard DO-214AC footprint Tape & Reel and Cut Tape options are available for both prototyping and production reels. The 500W peak pulse rating is specified at 25°C; at 125°C ambient the power capability derates to roughly 80% of the 25°C value — a margin to account for in high-temperature designs.","metaTitle":"SMAJ33CAE3/TR13 TVS Diode – 500W Bidirectional, DO-214AC","metaDescription":"SMAJ33CAE3/TR13 Zener TVS, 500W peak pulse, bidirectional, 33V standoff, DO-214AC.
