1500W bidirectional TVS — AEC-Q101 qualified
The 1.5KE10CAHE3_A/D: It clamps at 14.5V maximum with a 103A peak pulse current handling, and its 8.55V reverse standoff voltage means it stays transparent on a 5V or 12V rail until a transient exceeds that threshold. The DO-201AA axial package (DO-27 equivalent) is a through-hole form factor suited for point-of-use transient clamping on power inputs or relay coils.
Protection envelope and sourcing posture
The minimum breakdown voltage is 9.5V, ensuring the device starts conducting before the 14.5V clamp level is reached — this window protects downstream silicon from overvoltage without nuisance triggering on normal rail ripple. The single bidirectional channel covers both positive and negative transients in one package, saving board space vs two unidirectional diodes in series.
