The 44.7 V minimum breakdown voltage gives a 4.5 V guard band above the 40.2 V standoff level before the diode starts conducting leakage current. At the high end, the junction temperature derates the peak pulse power; the 1500 W rating holds at 25°C and must be linearly derated to zero at 175°C per the standard TVS derating curve. ## Package and board integration DO-201AA (DO-27) axial-lead through-hole package — the 1.5KE body diameter and lead spacing match standard 0.35-inch (8.9 mm) lead forming for PCB insertion. The axial leads handle the thermal cycling of the 1500 W pulse without cracking the glass passivation junction. Supplied in Tape & Box (TB) — the TB format is a bulk tray with taped leads for manual or semi-automated insertion, not continuous reel feed. For high-volume pick-and-place, the axial leads require forming and cut-tape handling; verify feeder compatibility before committing the line.","metaTitle":"1.5KE47CA-E3/73 Vishay TVS, 1500W Bidirectional, 40.2V","metaDescription":"Vishay 1.5KE47CA-E3/73 TransZorb TVS diode, 1500W peak pulse, 40.2V reverse standoff, bidirectional, DO-201AA axial.
