At the full 9.1A peak pulse current the clamp voltage reaches 165.1V — the number to compare against your downstream component's absolute maximum rating. ## Junction temperature range and package constraints The SQ-MELF C package is a surface-mount cylindrical body; the metalized ends are the anode and cathode. Reflow profile needs a longer soak zone than a standard SOT-23 to avoid tombstoning — the cylindrical shape rocks if paste volume is uneven. Microchip lists the 1N6168AUS as Active. The base product number 1N6168 covers the family; the AUS suffix denotes the bidirectional SQ-MELF variant.","metaTitle":"1N6168AUS – 1500W Bidirectional TVS Diode, SQ-MELF","metaDescription":"1N6168AUS from Microchip: 1500W peak pulse power, bidirectional, 91.2V standoff, 165.1V clamp, SQ-MELF package.
