At 6.05V reverse standoff (typ), the device sits below the breakdown threshold during normal operation; when a transient exceeds 6.75V minimum breakdown, the diode clamps the voltage to 11.7V maximum at 128A peak pulse current, protecting whatever load sits behind it. The 1500W peak pulse rating (10/1000 µs waveform) means it survives a single-event transient of that energy without degradation — the 128A peak current figure tells you how much charge the clamping node must handle at the defined pulse width. ## Thermal and packaging reality In practice, clamping a 1.5kW transient raises the junction temperature significantly, so the leads and board pad area must carry heat away. The axial form factor gives you a longer thermal path to the board than a surface-mount part; lead length and pad design matter for repeatability. ## Sourcing — this part is obsolete Vishay General Semiconductor marked this part obsolete. For existing equipment that specifies this exact order code, independent distribution and surplus channels are the procurement path — availability and lot-specific condition confirmed at RFQ.","metaTitle":"Vishay 1N6268-E3/73, 6.05V TVS, 1.5kW, DO-201AA","metaDescription":"Obsolete — Vishay 1N6268-E3/73 unidirectional TVS diode, 6.05V standoff, 1.5kW peak pulse, DO-201AA axial.
