This window means a 5 V or 6 V rail is protected: the diode stays transparent below 6.63 V, starts conducting at 7.38 V, and holds the line at 12.5 V during the surge. ## Through-hole DO-201AA axial package Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE8.2-/73 mounts through-hole on the PCB. The axial body and 0.052-inch lead diameter handle the 1500 W pulse without vapor-traces — the copper pad area and lead length set the thermal impedance for repetitive surges. The wide junction temperature margin means derating for high ambient is straightforward — at 125°C the peak pulse power is roughly 50% of the 25°C rating, per the TransZorb derating curve. ## Obsolete — sourced through independent channels Vishay lists the 1.5KE8.2-/73 as obsolete. The TransZorb series includes many 1500 W axial TVS diodes with similar footprint and electrical characteristics. A cross-reference to a functionally equivalent part from the same family can be evaluated against the specific clamping and standoff requirements of the application.","metaTitle":"1.5KE8.2-E3/73 Vishay TransZorb TVS, 1500W, DO-201AA","metaDescription":"Vishay 1.5KE8.2-E3/73 TransZorb TVS diode, 1500W peak pulse, 12.5V clamp, DO-201AA axial.
