The 1.5KE9.1CAHB0G: Housed in a DO-201AA (DO-27) axial leaded package, it mounts through-hole — the DO-201 footprint is standard for 1500W TVS diodes and mates with common PCB layouts for this power class.
The base product number is 1.5KE9.1, making the HB0G suffix the automotive AEC-Q101 variant.
The 7.78V reverse standoff allows it to sit on a 7.78V rail without conducting in standby.
