The 1.5KE150CA-G: The 128 V reverse standoff voltage defines the DC rail it protects — a 128 V bus or lower stays below the leakage knee. Clamping starts at 142.5 V typical breakdown and holds the transient to 207 V maximum at the 7.25 A peak pulse current. The single-channel layout keeps the PCB footprint to one axial hole pair.
Package, mounting, and thermal environment
Supplied in the DO-201AA / DO-27 axial-lead package, the body is through-hole mounted. The DO-201 suffix in the supplier device package field confirms the standard lead form and body diameter for this power class. Packaged in Tape & Box (TB) — the axial leads are taped for automated insertion, then boxed.
Comchip Technology lists the 1.5KE150CA-G as Active on the lifecycle record.
