Zener TVS diode for general-purpose surge clamping
The 1N6118AE3/TR is a bidirectional Zener TVS diode from Microchip Technology, designed to clamp transients on general-purpose circuits. Its single bidirectional channel means one device handles surges of either polarity — useful on AC signal lines or symmetric DC rails where board space is tight. Rated for a peak pulse power of 500 W under the 10/1000 µs waveform, it can absorb substantial energy from lightning, inductive kickback, or ESD events. The 31.4 V minimum breakdown voltage sets the clamping threshold; the 45.7 V maximum clamping voltage at 10.9 A peak pulse current defines the voltage the protected circuit must survive.
The 25.1 V reverse standoff voltage is the maximum continuous DC voltage the diode can withstand without conducting — your rail must stay below this. The 31.4 V minimum breakdown is where the diode starts to avalanche; the 45.7 V clamp is the worst-case voltage seen by the load during a 10.9 A surge. A 30 V rated bus would be marginal; a 24 V rail has comfortable margin. No power line protection — this device is not intended for continuous overvoltage clamping on mains or power distribution; it is a transient suppressor, not a crowbar or a regulator.
