This is the part that catches a load-dump or inductive kick before it reaches the downstream silicon. ## Package and board-fit Through-hole axial package in DO-201AA / DO-27 form factor — the 1.5KE footprint is a standard across TVS families. The leads solder into a plated through-hole board; the body stands off the board surface. No special pad geometry beyond the standard DO-201 land pattern. That covers the full industrial temperature band and reaches into automotive under-hood environments where the ambient near the ECU sees 125°C and the junction climbs higher under surge. The TransZorb series is built for repetitive surge duty in power supplies, motor drives, and automotive load-dump protection.","metaTitle":"1.5KE47A-E3/73 Vishay TransZorb TVS, 1500W, 40.2V Standoff","metaDescription":"Vishay 1.5KE47A-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 40.2V reverse standoff, DO-201AA axial.
