The axial leads suit point-to-point wiring or PCB mounting with standard 0.100-inch pitch holes — the same footprint used by legacy 1.5KE-series parts, so a board already laid out for the series accepts this variant without changes. The single bidirectional channel protects one signal or power rail; no polarity concern since it clamps equally in both directions. Listed as Active in production status, the 1.5KE39CAHA0G remains a current catalog item from Taiwan Semiconductor.","metaTitle":"1.5KE39CAHA0G TVS Diode, 1500W, 33.3V, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE39CAHA0G bidirectional TVS diode, 1500W peak pulse power, 33.3V standoff, AEC-Q101 qualified.
