What the 1N6161A protects and how it is rated
Its 1500W peak pulse power rating (10/1000µs waveform) means it can absorb a 17.6A surge before the clamping voltage hits 85.3V max — that is the hard ceiling the downstream circuitry sees during a strike.
Microchip lists the 1N6161A as Active.
Package and mounting — through-hole axial
through-hole mounting, axial-leaded package. The B, Axial case body is the standard DO-13 style — fits existing through-hole footprints for 1.5kW Zener TVS diodes. No surface-mount variant in this order code; if your board is SMT-only, look at the surface-mount equivalents in the same power class.
