When a surge exceeds the 14.3 V minimum breakdown, the device avalanches and clamps the transient to 21.2 V maximum. The 10/1000 µs waveform is the industry-standard test pulse for TVS diodes — an 8/20 µs surge would see a higher peak current capability, but the 10/1000 µs rating is the conservative figure for comparing parts across suppliers. ## Package and board integration — DO-201AA axial through-hole The DO-201AA (also known as DO-27) axial-lead package is a through-hole form factor that inserts into 0.040-inch diameter plated-through holes on a standard PCB. The 1.5KE body diameter is roughly 5.3 mm with a 25.4 mm lead length — the leads are tin-plated copper for solderability into the board. The junction temperature limit of 175°C is the thermal ceiling for repetitive surge events — a single 1500 W pulse at 25°C ambient raises the junction well below this limit. ## Sourcing posture — active, quoted to order The 1.5KE15A-/73 carries an active lifecycle status from Vishay.","metaTitle":"1.5KE15A-E3/73 Vishay TVS Diode, 1500W, 12.8V Standoff","metaDescription":"Active Vishay TransZorb 1.5KE15A-E3/73 TVS diode, 1500W peak pulse, 12.8V standoff, 21.2V clamp.
