The 225V minimum breakdown voltage ensures the device does not start clamping during normal operation, while the 360V clamp limits the voltage seen by the protected load during a surge. The 4.2A peak pulse current at the clamp voltage tells you the surge current the device can absorb — useful for sizing the trace width and the upstream fuse coordination. The bidirectional configuration (single device clamps both polarities) saves board space compared to back-to-back unidirectional diodes on an AC line. ## Sourcing an obsolete TransZorb for a legacy BOM Vishay has marked the 1.5KE250C-/54 as obsolete. For a production line or a repair that depends on this exact order code, the supply path runs through independent distribution — surplus and new-old-stock lots are the available channel.","metaTitle":"1.5KE250C-E3/54 Vishay TVS, 1500W Bidirectional, DO-201","metaDescription":"Obsolete 1.5KE250C-E3/54 Vishay TransZorb® TVS diode, 1500W peak pulse, 202V standoff, 360V clamp.
