Automotive-grade TVS with 1500 W pulse capacity
The 1.5KE47CAHE3_A/D: It is qualified to AEC-Q101, making it suitable for automotive load-dump and transient protection on 24 V or 28 V vehicle buses.
What the key ratings mean for the BOM
40.2 V reverse standoff means the diode draws negligible leakage below that rail voltage — it stays invisible to the protected circuit until a transient exceeds the threshold. Breakdown starts at 44.7 V min, and clamping is hard-limited to 64.8 V at 23.1 A peak pulse current.
Package and board integration
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE47CAHE3_A/D mounts with standard 0.040-inch diameter holes. The bidirectional configuration uses a single device for both positive and negative transients — one part covers both polarities, saving board space over a back-to-back pair.
