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.","metaTitle":"1N6118A Zener TVS Diode – 500W, 31.4V Breakdown, Active","metaDescription":"1N6118A Zener TVS diode from Microchip Technology. 500W peak pulse power, 31.4V min breakdown, 45.7V clamping, -55°C to 175°C.

Both share the same 500 W peak pulse power, 45.7 V clamping voltage, and axial package, but the 'A' suffix typically indicates a ±5% breakdown voltage tolerance versus the standard ±10%.
