The bidirectional channel means polarity does not matter — one part guards a signal pair or a floating supply without orientation. ## Peak power and clamp voltage — the real protection envelope 600W peak pulse at 10/1000µs is the industry-standard rating for this package class. The actual energy absorbed depends on the surge waveform: a shorter 8/20µs pulse can deliver higher peak current, but the 10/1000µs rating is the conservative baseline for telecom surge testing (ITU-T K.20/K.21) and industrial IEC 61000-4-5. The 77V clamp is the voltage the load sees during the pulse — downstream parts must survive that ceiling. The DO-204AC / DO-15 axial body is a standard through-hole footprint — hand-assemblable, easy to inspect, and compatible with existing board layouts that use a 0.025-inch lead diameter. ## Sourcing and compliance check The base product number is P6KE56, so this -B suffix variant is the bulk-packaged, bidirectional, 600W member of the P6KE family.","metaTitle":"P6KE56CA-B Diodes Inc TVS, 600W, 77V Clamp, DO-15","metaDescription":"P6KE56CA-B Diodes Inc Zener TVS, 600W peak pulse, 77V clamping, DO-15 axial.
