The SQ-MELF (C) package is a surface-mount ceramic barrel — the same footprint as a standard MELF diode but with a square cross-section for better solder-joint inspection. It operates across the -55°C to 175°C junction temperature range. ## Package and mounting At 1500 W peak pulse power, this part absorbs a 6.9 A surge. The 218.4 V clamp voltage is the ceiling the rail sees during the event — if the protected circuit's absolute-max rating sits below that, you need a lower-voltage TVS or a secondary clamp. The 152 V minimum breakdown voltage gives margin above the 121.6 V standoff — that window keeps the diode off during normal line ripple and only fires when a real transient arrives. ## Active production and ordering posture The base product number is 1N6171; the 'AUS' suffix denotes the SQ-MELF package variant.
