TVS diode with 1.5 kW pulse rating and 342 V standoff
The 1.5KE400A-E3/73: Its 342 V reverse standoff voltage protects 380 V nominal rails, clamping transients at 548 V maximum while conducting 2.7 A peak pulse current.
What the clamping voltage means for rail protection
A 548 V clamp at 2.7 A Ipp means the TVS limits overvoltage on a 342 V DC bus to under 550 V during a surge — critical for downstream MOSFETs and DC-DC converters with 600 V abs-max ratings.
Package and mounting for through-hole assembly
Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mount — the lead bend and body length match standard TVS footprints for 1.5 kW class parts. The Tape & Box (TB) packaging suits hand-insertion or vibratory bowl feed; the axial leads require no special soldering profile beyond typical wave or hand-solder processes.
