The 9.9V reverse standoff voltage sets the maximum DC operating level before the device starts clamping; the 12.35V minimum breakdown and 18.2V maximum clamping at 82.4A peak pulse current define the protection window. Bidirectional single-channel configuration suits AC or bipolar signal lines. ## Temperature range and package Junction temperature range -55°C to 175°C — this covers military/aerospace and downhole environments. Supplied in a SQ-MELF (C) surface-mount package. The MELF barrel footprint requires careful solder-paste volume control during reflow to avoid tombstoning.","metaTitle":"1N6145AUS Zener TVS – 1500W, 9.9V, SQ-MELF, Active","metaDescription":"Microchip 1N6145AUS Zener TVS diode, 1500W peak pulse, 9.9V reverse standoff, SQ-MELF package, -55°C to 175°C.
