That is the voltage the TVS holds the protected line to during a surge event — design the downstream circuitry to withstand at least that peak without damage. This is a single-channel unidirectional device, meaning it clamps only positive transients above the breakdown voltage; for bidirectional protection on AC or bipolar rails, two devices back-to-back or a dedicated bidirectional part is needed. ## Standoff voltage and breakdown threshold Minimum breakdown voltage is 94.4 V, so the device starts clamping between those two levels. Housed in a DO-214AC (SMA) surface-mount package, supplied on tape and reel. Operating junction temperature range is -65°C to +150°C.","metaTitle":"SMAJ85E3/TR13 TVS Diode – 85V Standoff, 151V Clamp, Active","metaDescription":"Microchip SMAJ85E3/TR13 Zener TVS, 85V reverse standoff, 151V clamping at 3.3A, 500W peak pulse, DO-214AC.
