Product details

1.5 kW surge clamp for 100 V rails

The 1.5KE120A-E3/54: The Vishay 1.5KE120A-/54 is a 1500W TransZorb® TVS diode designed to clamp transients on nominal 100 V DC rails.

What the ratings mean for your protection design

The 102 V standoff means the diode will not conduct leakage current on a rail that stays below that level, but a sustained overvoltage above 114 V triggers breakdown.
