1.5 kW peak pulse in an axial DO-201 package
The 1.5KE22AHB0G: It clamps a transient at 30.6 V maximum while the reverse standoff voltage sits at 18.8 V — the rail stays protected without conducting during normal operation. A single unidirectional channel handles up to 51 A of peak pulse current, making this part suitable for clamping surges on 12 V or 24 V automotive power buses where the steady-state line voltage stays below 18.8 V.
The DO-201AA (DO-27) axial-lead package is a through-hole form factor common in high-reliability power-supply and battery-line clamping circuits where board-level rework or high surge current demands a leaded package over a surface-mount alternative.
Active production — sourcing and quoting
It is available through independent distribution channels; pricing and lead time are confirmed at the time of RFQ against the specific BOM quantity. No power line protection is built in — this is a pure transient suppressor, not a crowbar or active clamp. The breakdown voltage range (20.9 V min) and clamping voltage (30.6 V max) define the protection window for the downstream circuitry.
