12V rail protection – 500W peak pulse, Axial through-hole
The 1N6463 is a single-direction Zener TVS diode from Microchip Technology, designed to clamp transients on a 12V nominal rail. Its reverse standoff voltage is 12V, meaning the diode does not conduct at normal line voltage; when a surge exceeds the 13.6V minimum breakdown, it clamps at 22.6V maximum and shunts up to 125A of 8/20µs peak pulse current. The 500W peak pulse power rating defines the energy it can absorb in a single surge event — a key number for derating against the expected transient energy on an industrial control or telecom line.
The B, Axial package is a through-hole form factor — the lead spacing and body diameter match standard 0.100-inch pitch board layouts.
Sourcing and compliance – authorized channel, RoHS
As an Active Microchip part, the 1N6463 is available through authorized distribution. The part is RoHS compliant per standard Microchip declarations. For volume BOM positions, the exact ordering code 1N6463 is the through-hole Axial variant — no suffix for tape or reel, since the package is Bulk. Quoted to order against your line-item quantity.
