The 1N6267AHE3_A/C is a unidirectional Zener-based transient voltage suppressor — the TransZorb designation means Vishay's avalanche-characterized Zener construction, designed to clamp a transient surge rather than block continuous overvoltage. It is AEC-Q101 qualified, placing it in the automotive screening flow for defect rates and lot traceability. At that waveform the clamping voltage holds at 10.5V maximum with a peak surge current of 143A; the reverse standoff sits at 5.8V typical, defining the normal working window the diode sees before a transient triggers. The minimum breakdown of 6.45V gives the clamping margin above the standoff rail.
Operating range and package fit for under-hood deployment
The DO-201AA (DO-27) axial package is the through-hole TVS diode standard; it mounts on a PCB with leads sized for wave or hand soldering and handles the thermal cycling associated with engine bay boards without a specialized heatsink. Tape-and-reel packaging is the production reel format — confirm reel orientation and lead forming requirements for your pick-and-place or through-hole insertion line before committing to the BOM quantity.
