Its 500 W peak pulse power rating (10/1000 µs waveform) handles moderate surges typical of industrial control, telecom, and power-supply inputs, while the 45.7 V clamping voltage keeps downstream semiconductors below their absolute-max rating during an event.
Clamping voltage and breakdown — the numbers that matter for BOM fit
With a minimum breakdown voltage of 31.4 V and a maximum clamping voltage of 45.7 V at the rated peak pulse current of 10.9 A, this part suits 24 V or 28 V rails where the transient must be clamped below 48 V. The 25.1 V reverse standoff voltage means the diode does not conduct at normal operating levels on a 24 V bus.
Package and temperature range for through-hole assembly
Supplied in a through-hole axial package (B, Axial), the 1N6118A is a drop-in for existing board layouts using 0.025-inch lead diameter holes.
