It reflows well with standard solder paste but can roll during placement if the pick-and-place nozzle or vacuum pad isn't centred. Under hot air, the body heats evenly — no hidden thermal pad to worry about — but the part must be fixtured or held with tweezers until the solder solidifies. The package is marked; confirm pin 1 orientation by the cathode band (the bidirectional part may have a single band or no band — verify against the marking specification in the datasheet before assembly). ## Active production and sourcing posture The base product number is 1N6118, and the 'AUS' suffix denotes the surface-mount SQ-MELF variant. This part is sourced to order through our supply channel — submit an RFQ for a firm lead time and price.","metaTitle":"1N6118AUS Zener TVS Diode – 500W Bidirectional, SQ-MELF","metaDescription":"1N6118AUS Zener TVS diode from Microchip Technology. 500W peak pulse power, 25.1V reverse standoff, bidirectional, SQ-MELF surface mount.
