1500W peak pulse — clamping a 6.8V rail
The 1.5KE6.8CA: With 1500W peak pulse power handling, it absorbs surge energy without letting the protected line exceed the clamp voltage — critical for a 5V or 3.3V supply bus where a 12V spike would kill the downstream IC.
DO-201 axial — through-hole transient protection
Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE6.8CA mounts through-hole — the leads handle the thermal cycling of repetitive surges better than a surface-mount equivalent in the same power class.
Active production — no last-time-buy pressure
That means the part remains in the standard catalog for new designs and replacement orders alike. No official successor or cross-reference exists within the 1.5KE family because this is the current production variant.
