1.5 kW peak pulse in a DO-201AA axial package
The 1.5KE24A-E3/54: The 22.8 V minimum breakdown voltage means the device starts conducting between 22.8 V and the clamp voltage, protecting a 20.5 V rail from transients without interfering with normal operation.
Where the ratings land for a BOM decision
The 1500 W peak pulse rating at 10/1000 µs defines the energy-handling capacity for a single surge — enough to clamp a 33.2 V spike from a 24 V nominal bus in industrial or telecom gear. The DO-201AA (DO-27) axial leaded package is a through-hole form factor — it stands up off the board, so the leads absorb mechanical shock and the body dissipates heat into the solder joint and trace copper.
