Product details

1500 W peak pulse, 23.1 V standoff — the protection window

The 1.5KE27C: Peak pulse power is rated at 1500 W for a 10/1000 µs waveform, corresponding to a peak current of 40.5 A at the maximum clamping voltage of 39.38 V.

Through-hole axial package for legacy and high-reliability boards

This makes the part suitable for outdoor enclosures, engine compartments, and other environments where ambient temperature can exceed 85°C.

Obsolete — sourcing through independent channels

Littelfuse has marked the 1.5KE27C as obsolete. The part is available through independent surplus and broker channels, with quantities and pricing confirmed at the time of RFQ.
