Automotive-grade transient suppressor, 1500 W peak pulse
The 1.5KE39CAHB0G: The 33.3 V reverse standoff suits 24 V automotive systems where nominal rail voltage sits at 28 V during alternator charging; the 37.1 V minimum breakdown ensures the TVS does not conduct during normal operation.
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.
