No official successor order code is recorded for this part. Sourcing is through independent distribution channels; availability and pricing are confirmed at RFQ against the BOM quantity. ## Clamping performance — 344V at 4.4A This bidirectional TransZorb TVS diode clamps at 344V maximum when hit with a 4.4A peak pulse current (10/1000µs waveform). The 214V reverse standoff voltage means the protected line can ride through normal 214V DC without the diode conducting leakage. Rated for 1.5kW peak pulse power, the 1.5KE250CA-/54 absorbs transient energy from lightning-induced surges, inductive load switching, or ESD events in general-purpose DC bus and telecom circuits. ## Breakdown window and temperature range Minimum breakdown voltage is 237V, so the diode starts conducting between 237V and the 344V clamp ceiling.","metaTitle":"1.5KE250CA-E3/54 Vishay TVS, 344V Clamp, 1.5kW","metaDescription":"Vishay 1.5KE250CA-E3/54 TransZorb TVS diode, 214V standoff, 344V clamp, 1.5kW peak pulse.
