The 3.6 A peak pulse current rating at the 10/1000 µs waveform tells you the maximum surge this part can absorb — useful for sizing the upstream fuse or PTC to coordinate protection. ## Through-hole package and board fit Housed in a DO-201AA (DO-27) axial-lead package, this is a through-hole part that hand-solders easily — no hot-air station needed, just a clean iron and a bit of flux. The 1.5KE supplier device package marking is consistent across the series, so a replacement from the same family drops into the same board holes.","metaTitle":"1.5KE300A-E3/73 Vishay TVS, 1.5kW, 414V Clamp, DO-201AA","metaDescription":"Vishay 1.5KE300A-E3/73 TransZorb TVS diode, 1500W peak pulse, 256V reverse standoff, 414V clamp.
