The 1.5KE56CAHE3_A/C: For a procurement desk qualifying a TVS into an automotive BOM, this removes the single-source lifecycle risk that often triggers a respin when a protection diode goes NRND.
1500W peak pulse — the headline rating and what it means for fit
The 47.8 V reverse standoff means the diode stays transparent on a nominal 48 V bus or a 12 V automotive rail with load-dump transients — it only conducts when the line exceeds the standoff threshold.
AEC-Q101 qualification — the deployment envelope
AEC-Q101 qualified and part of the TransZorb® series, this diode is screened for automotive-grade reliability: temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive stress test profile. The -55°C to 175°C operating junction range covers under-hood and engine-bay environments where a standard commercial TVS would derate or fail.
DO-201AA axial package — board-fit and mounting
Through-hole mounting in a DO-201AA (DO-27) axial package. The lead spacing and body diameter match the standard TVS footprint used across the 1.5KE family — no board layout change if migrating from another 1.5KE56 variant. Tape-and-reel packaging supports automated insertion for volume builds.
