Obsolete AEC-Q101 TVS — sourcing reality
The 1.5KE130CAHE3/51: This part carries AEC-Q101 automotive qualification, making it suitable for 12 V and 24 V vehicle electrical systems where transient suppression is required on power rails or signal lines exposed to load-dump and inductive kickback. Sourcing is through independent surplus channels; quantities and pricing are confirmed at RFQ.
Parametric profile and fit
The 111 V reverse standoff voltage means the TVS does not conduct during normal 12 V or 24 V bus operation, but clamps at 179 V when a transient exceeds the 124 V minimum breakdown threshold. Bidirectional construction (single channel) protects against both positive and negative transients on the same line — no polarity concern during installation. Housed in a DO-201AA (DO-27) axial-lead package, it mounts through-hole on the PCB — the lead bend radius and hole diameter follow standard axial diode footprint guidelines.
