At the 29 A peak pulse current (10/1000 µs), the clamping voltage reaches 53.9 V maximum. That figure sets the voltage stress the protected device sees: a downstream DC-DC converter rated at 60 V abs-max has 6 V of headroom above the clamp, so the TVS absorbs the surge before the converter's input FET avalanches. The DO-201AA (DO-27) axial-lead package suits point-to-point wiring or PCB through-hole mounting. The bulk packaging is typical for high-volume panel assembly where axial components feed into a radial inserter. The single bidirectional channel clamps both polarities, eliminating the need for two series diodes in a unidirectional configuration. ## Active production — sourcing posture The AEC-Q101 certification is backed by the manufacturer's PPAP documentation — a requirement for automotive tier-1 submittals.","metaTitle":"1.5KE39CAHB0G TVS Diode, 1500W, 33.3V, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE39CAHB0G bidirectional TVS, 1500W peak pulse, 33.3V standoff, AEC-Q101 automotive grade.
