The body is small enough for tight layouts but large enough to hand-solder with a fine iron if you are doing a field swap — just watch the polarity marking. Microchip Technology is the sole manufacturer; no official second-source cross-reference is published. For BOM planning, the part is sourced per RFQ against your quantity.","metaTitle":"SMAJ45AE3/TR13 Zener TVS Diode – Microchip, 500W, DO-214AC","metaDescription":"SMAJ45AE3/TR13 Zener TVS diode, 500W peak pulse power, 45V standoff, 72.7V clamp.
