300V standoff, 482V clamp — what the ratings mean for your rail
The P6KE350A-T: When a transient exceeds the 332V minimum breakdown voltage, the device clamps at 482V maximum (at 1.25A peak pulse current), limiting the overvoltage stress on downstream components. The 600W peak pulse rating (10/1000 µs) defines the energy-handling capability for a standard lightning or inductive-switch surge. The actual peak current at the clamp voltage is 1.25A, so the TVS absorbs the transient energy as heat across the junction.
DO-15 axial package and wide temperature range
Housed in the DO-204AC (DO-15) axial-lead package, the P6KE350A-T mounts through-hole and is suitable for point-of-use transient suppression on power supply rails or signal lines in industrial and telecom equipment. The operating junction temperature range spans -55°C to +175°C, covering cold-start conditions and high-ambient environments such as outdoor cabinets or motor drive bays.
