1500W peak pulse – what it means on your rail
The 1N6040A/TR: Rated at 1500 W peak pulse power. That is the energy it can clamp once before the junction temperature recovers – enough for a 9 V rail where the breakdown starts at 10.5 V min and the clamp holds at 15.6 V max while passing 96 A of peak pulse current.
DO-13 through-hole – field-swappable
DO-13 package, through-hole mount. No hot-air station needed – a soldering iron and a pair of cutters will swap it on site. The Tape & Reel option suits automated insertion if you are building new boards.
Junction temperature range from -55°C to 175°C. That covers engine-bay electronics, outdoor telecom cabinets, and industrial control panels without derating the pulse power at the hot end.
