The reverse standoff of 53 V is the continuous DC rail voltage the diode can sit across without degrading — a 48 V supply with 5 % tolerance stays comfortably below this level. The wide Tj max of 175 °C means the device absorbs the rated 1500 W pulse without derating at elevated ambient, as long as the average power stays within the thermal limits of the DO-201AA package. The DO-201AA (also known as DO-27) axial-lead through-hole package is the standard for 1.5 kW TVS diodes. Lead spacing and body diameter match legacy footprint patterns, and the axial leads handle manual or wave-solder insertion into plated through-holes on single-layer or multi-layer boards. The 1.5KE package marking is the supplier device code. ## Active production — current lifecycle for a long-running TransZorb series The TransZorb series has been in continuous production for decades, and the 1.5KE62CA-/73 remains a current, orderable line item.","metaTitle":"Vishay 1.5KE62CA-E3/73 TransZorb TVS, 1500W, 85V Clamp","metaDescription":"Vishay 1.5KE62CA-E3/73 TransZorb bidirectional TVS diode, 1500W peak pulse, 53V standoff, 85V clamp.
