The minimum breakdown voltage is 122V, so the rail must stay below that to avoid leakage. ## 500W pulse — sizing for the transient That 500W is the product of the clamping voltage and the peak current — at 196V clamp, the device handles 2.6A for that pulse width. For shorter transients (e.g. 8/20 µs), the peak current capability is higher, but the datasheet's derating curve must be followed. The 500W rating is the absolute maximum at 25°C; derate linearly above that per the datasheet. That saves a diode in the bill of materials compared to using two unidirectional TVS devices back-to-back. The breakdown and clamping voltages are the same for both polarities. ## DO-214AC SMA — footprint and temperature range Housed in the standard DO-214AC (SMA) package, surface-mount. Microchip lists this part as Active. The part ships on Tape & Reel.","metaTitle":"SMAJ110CE3/TR13 Zener TVS Diode – 110V, 500W, DO-214AC","metaDescription":"SMAJ110CE3/TR13 Zener TVS diode, 110V reverse standoff, 500W peak pulse power, DO-214AC SMA package.

For AC lines, the peak voltage of a 110V RMS sine wave is about 155V, which exceeds the standoff voltage — this part is not suitable for direct 110V AC mains protection. It is intended for 110V DC bus clamping."},{"question":"Is SMAJ110CE3/TR13 RoHS compliant?","answer":"The part number suffix '' typically indicates RoHS compliance per Microchip's naming convention.
