600 W peak pulse, 85.5 V standoff — the TVS that guards a 48 V to 72 V rail
The P6KE100CA-T: Its 85.5 V reverse standoff voltage and 137 V clamping point make it a fit for protecting 48 V to 72 V DC buses in industrial power supplies, telecom rectifiers, and battery-charger outputs where a single transient event must not propagate into downstream converters.
Clamping, breakdown, and the operating margin
The minimum breakdown voltage is 95 V, and the maximum clamping voltage at the 4.4 A peak pulse current is 137 V. That 42 V window between breakdown and clamp defines the energy-absorption band — the TVS starts conducting at the knee and holds the rail below the downstream device's absolute maximum rating during the surge.
DO-15 axial — the through-hole workhorse
Housed in the DO-204AC (DO-15) axial-lead package, the P6KE100CA-T is a through-hole part suited for point-to-point wiring or PCB mounting where the lead bend radius and hole diameter follow the standard DO-15 footprint. The axial body allows the TVS to sit off the board for better convective cooling during repetitive pulse events.
Obsolete — sourcing through independent channels
Diodes Incorporated lists the P6KE100CA-T as obsolete. For a BOM sustaining a legacy design, the 600 W rating and DO-15 footprint are the cross-reference anchors — any replacement must match the 85.5 V standoff and bidirectional polarity.
