Zener TVS for 86.6V rail protection
Its 104.5 V minimum breakdown voltage and 151.3 V clamping ceiling make it a fit for protecting 86.6 V nominal rails — the reverse standoff voltage — against surges up to 3.3 A peak pulse current.
Breakdown and clamping margins
Breakdown starts at 104.5 V minimum, clamping the transient at 151.3 V maximum. That 46.8 V window between standoff and clamp gives the downstream silicon some headroom — useful when the rail rides near 86.6 V and the TVS must not leak at DC bias. The single bidirectional channel clamps both polarities, so a single device covers positive and negative transients on the same line — no need for back-to-back series diodes.
Active production, axial tape-and-reel
Microchip lists the 1N6131A/TR as Active. The B, Axial package with 0.50″ lead spacing fits standard through-hole layouts; the -55°C to 175°C junction temperature range covers military and industrial thermal environments.
