At the 1500 W peak pulse rating the diode clamps to 10.5 V maximum while conducting 143 A — this clamping voltage is the peak the protected circuit must survive without latch-up or oxide rupture. Single unidirectional channel; the cathode band on the DO-201AA axial package marks the anode for correct polarity insertion on a DC bus. ## DO-201AA axial package and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the part mounts through-hole — the lead diameter and body length match standard 0.100-inch pitch board layouts common in power entry and telecom line cards. Junction temperature range spans -55°C to 175°C, covering industrial enclosure ambient and the self-heating from repetitive pulse trains without derating below the 1500 W single-pulse capability.","metaTitle":"1.5KE6.8A-E3/73 Vishay TransZorb TVS, 1500W, 6.45V breakdown","metaDescription":"Active Vishay 1.5KE6.8A-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 10.5V clamping, 143A Ipp. DO-201AA axial.
