Rated for 500W peak pulse power, this part handles the energy of a typical industrial transient without exceeding the junction temperature limit of -65°C to 150°C. ## Parametric fit for 78V bus protection The minimum breakdown voltage is 86.7V, ensuring the diode does not conduct during normal 78V operation. Single unidirectional channel in a DO-214AC (SMA) package — the same footprint used across the SMAJ family, simplifying BOM consolidation if multiple voltage ratings are needed on the same board. ## Active production — standard sourcing Sourced to order against BOM quantities.","metaTitle":"SMAJ78AE3/TR13 Microchip Zener TVS Diode 78V 500W DO-214AC","metaDescription":"Microchip SMAJ78AE3/TR13 Zener TVS diode, 78V reverse standoff, 126V clamping, 500W peak pulse power.
