Product details

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.

Active production — sourcing posture

Tape & Reel or Cut Tape packaging options are listed.

Frequently asked questions

Where can I buy 1.5KE24A-/54 and how do I get a price?

The 1.5KE24A-/54 is sourced to order through independent and franchised distribution.

What does the 33.2 V clamp voltage mean for a 24 V bus?

The 33.2 V clamp at 45.2 A peak pulse current means the TVS holds the transient below the typical 36 V abs-max of downstream 24 V-rated ICs and modules, giving a 2.8 V margin before the load sees destructive overvoltage.
