1500 W transient clamp for 18.8 V rails
The 1.5KE22CAH: It clamps transients on a nominal 18.8 V rail — the reverse standoff voltage — and breaks down at 20.9 V minimum to start conducting, holding the clamp at 30.6 V maximum while shunting up to 51 A of surge current.
AEC-Q101 qualification and deployment context
The DO-201AA axial package (also known as DO-27) is a through-hole form factor that suits high-reliability point-to-point wiring or PCB mounting where the lead bend absorbs thermal cycling strain better than a surface-mount body.
