The reverse standoff voltage of 6.05 V sets the normal operating point — above 6.05 V the device begins conducting, and above the 6.75 V minimum breakdown voltage it is fully in its protection regime. ## Automotive qualification and thermal margin The TransZorb® designation is Vishay's branded implementation of the Zener-based TVS — it refers to a specific die construction and failure-mode target compared with a plain Zener used in a clamping role. ## Lifecycle and sourcing posture for 1N6268HE3/54 The part ships in Tape & Reel (TR) packaging on a DO-201AA (DO-27) axial body — the through-hole lead spacing and polarity stripe are the mechanical constraints that determine whether any alternative fits the existing board layout.","metaTitle":"Vishay 1N6268HE3/54 TVS Diode, 1.5kW Peak Pulse, Obsolete","metaDescription":"Obsolete Vishay 1N6268HE3/54 unidirectional TVS (TransZorb®), 6.05V standoff, 1.5kW peak pulse.
