The 1N6267HE3/73: At 139 A peak pulse current the clamping voltage sits at 10.8 V maximum, which means the protected rail sees a hard clamp at that level during the event. The 5.5 V reverse standoff is the continuous working voltage the TVS can block without conduction — the rail it sits across when the transient is absent. The 6.12 V minimum breakdown is where conduction begins on a rising overvoltage event, establishing the TVS's trigger point in the clamping chain.
AEC-Q101 — the automotive qualification frame
TransZorb® is Vishay's trademark for its glass-passivated Zener TVS die in an axial package. The -55 °C to 175 °C junction temperature range reflects the die and package combination; the actual board-side limit is set by the thermal pad and surrounding components.
DO-201AA axial package — through-hole TVS integration
The DO-201AA (DO-27) axial body is the standard through-hole outline for 1.5 kW TVS diodes — the lead diameter and body length give the thermal path needed to dissipate the energy during a clamping event without exceeding the junction limit. Mounting is vertical or horizontal in a punched or-formed lead bend; the cathode band marks the Zener polarity. Through-hole assembly is compatible with wave-solder and hand-solder profiles; no reflow profile applies to this package type.
