Product details

Transient protection for signal and low-power DC rails

The 1.5KE24A-B: The through-hole DO-201 axial package suits point-to-point wiring on terminal strips or PCB through-hole layouts where a replacement part must drop into an existing board without a layout change.

Clamping window and breakdown margin

The minimum breakdown voltage is 22.8 V, giving a 2.3 V margin above the 20.5 V standoff — enough to avoid false triggering from normal rail ripple while clamping before the protected device's absolute maximum rating is exceeded.

Obsolete — sourcing through independent channels

Sourcing is limited to independent distribution and surplus inventory, where each lot is verified for authenticity and tested to the original datasheet limits before shipment.

Frequently asked questions

What is the closest pin-compatible alternative to the 1.5KE24A-B?

No official pin-compatible successor is recorded from Diodes Incorporated. A functionally equivalent TVS with the same 20.5 V standoff, 1500 W peak pulse rating, and DO-201 package from another manufacturer would require a cross-reference search at RFQ time — no direct drop-in replacement is documented.
