Breakdown occurs at a minimum of 36.7 V, and the clamping voltage at peak pulse current (8.5 A) is 59 V max — that window between breakdown and clamp is the energy absorption zone. For a 33 V supply, this margin ensures the TVS does not trigger on ripple but still catches transients before they reach downstream silicon. Microchip lists the SMAJ33E3/TR13 as Active. For volume BOM positions, this part can be quoted to order against your quantity — no supply-chain discontinuity to plan around. The Zener type and unidirectional channel make it suitable for DC rail protection in power supplies, motor drives, and general-purpose circuit boards where a single polarity clamp is needed.","metaTitle":"SMAJ33E3/TR13 — Microchip 33 V Zener TVS, 500 W, DO-214AC","metaDescription":"SMAJ33E3/TR13 Zener TVS diode, 33 V reverse standoff, 500 W peak pulse, DO-214AC surface mount.
