TVS clamping and standoff ratings
The 1N6270AHE3_A/C clamps at 13.4 V maximum under a 112 A, 10/1000 µs surge pulse — the 7.78 V reverse standoff sits below the 8.65 V minimum breakdown, giving a design engineer controlled headroom before the diode turns on. For a 12 V automotive rail, a 7.78 V standoff keeps the protected node below its maximum working voltage during normal operation while the clamping ceiling of 13.4 V limits what reaches the downstream circuitry during a load-dump or inductive kick event. That 5.62 V gap between standoff and clamping is the transient absorption window.
1500 W peak pulse dissipation in the DO-201AA axial package means this part handles the short-duration transients typical of automotive load-dump profiles without sacrificing board real estate.
Lead time and current pricing are confirmed against the BOM quantity at RFQ. The DO-201AA axial form factor and the AEC-Q101 automotive grade mean the part carries traceability requirements that an authorized-channel quote will document. If your program requires PPAP-level compliance data, request the automotive documentation package at quote time.
