AEC-Q101 qualification and temperature range
The 1.5KE56AH carries AEC-Q101 automotive qualification, meaning it has passed the stress tests (temperature cycling, HTRB, H3TRB) required for under-hood and chassis-mounted electronics. The unidirectional design (single channel) clamps positive transients only; for bidirectional protection on AC or bipolar rails, a different ordering code from the same 1.5KE family is needed.
Through-hole DO-201 package for high-reliability assembly
The tape-and-reel packaging option supports automated insertion for volume production, though the axial form factor requires a compatible feeder or hand-placement for low volumes.
