It protects an 85V nominal rail with a breakdown voltage of 94.4V min and clamps transients to 137V max at 3.6A peak pulse current. The DO-214AC (SMA) package is a common surface-mount footprint that reflows on standard Pb-free profiles. No power line protection feature — this is a unidirectional device for DC rail clamping. ## Clamping voltages and thermal limits Above that, the device breaks down at 94.4V min and clamps the transient to 137V max. The 3.6A peak pulse current rating is the current the diode can sink during the 10/1000µs surge without exceeding the 500W peak pulse limit. The wide range means derating for ambient temperature is minimal in most commercial applications. ## Active production, tape-and-reel supply","metaTitle":"SMAJ85AE3/TR13 Microchip 500W Zener TVS, DO-214AC, Active","metaDescription":"SMAJ85AE3/TR13: 500W peak pulse power, 85V standoff, 94.4V breakdown, 137V clamp, DO-214AC.
