Transient suppression at 1.5 kW peak
The 1N6268A-E3/73: The 1N6268A-/73 sits in the 1.5KE TransZorb® family — Vishay's TVS-diode classification for Zener-based transient voltage suppression rather than pure voltage-reference Zener duty. The reverse standoff of 6.4 V sets the keep-out voltage where the device remains off during normal operation; breakdown starts at 7.13 V minimum.
High-temperature junction rating
Operating junction temperature runs from -55 °C to 175 °C — the upper bound gives real thermal headroom in outdoor or poorly ventilated enclosures where ambient can spike well above 85 °C. A 175 °C TJ with a DO-201AA axial leadframe and package means the device dissipates transient heat through the leads into the PCB copper, so lead dress and pad area matter more than a surface-mount thermal pad.
Axial through-hole for panel and wire-entry protection
DO-201AA axial package mounts on standard 0.4-inch lead spacing; the Tape & Box packaging variant ships on a straight-taped reel rather than ammo-pack or reel-on-reel. Through-hole termination handles higher current and vibration better than gull-wing — the lead solder fillet absorbs mechanical shock at the board interface. Power line protection is listed as No, so this part guards signal and low-power rails, not the AC mains entry point.
