1500 W peak pulse in a through-hole axial package
The 1.5KE120CAHA0G: The 102 V reverse standoff voltage means it stays transparent on a nominal 100 V bus, only conducting when the line exceeds the 114 V minimum breakdown threshold.
Graded Automotive and qualified to AEC-Q101, this part is screened for the reliability stresses expected in under-hood and chassis-mounted electronics — temperature cycling, high-temperature reverse bias, and ESD robustness. No power line protection is built in; it is a pure transient suppressor, not a filter.
Housed in a DO-201AA / DO-27 axial-lead through-hole package (supplier device package DO-201), the 1.5KE120CAHA0G is supplied in Tape & Box. The axial leads suit point-to-point wiring or PCB through-hole mounting with a standard 0.100-inch pitch footprint. The body diameter and lead spacing match the common DO-201 land pattern — no board spin needed if replacing a similar axial TVS.
The base product number 1.5KE120 covers the family; the HA0G suffix indicates the automotive AEC-Q101 grade and the Tape & Box packaging.
