The 5.5A continuous output rating covers a 3.3V rail at 18W or a 12V rail at 66W before derating — enough for most peripheral, sensor, or sub‑regulator feeds in industrial and telecom gear. The 125°C junction temperature rating lets this eFuse sit next to a hot switching regulator or inside a sealed enclosure without forced air. ## Sourcing posture for a BOM line The pad connects to the GND plane through multiple vias — the thermal resistance to the board depends on the copper area and via count, not the package alone.","metaTitle":"TPS259470ARPWR eFuse 2.7V-23V 5.5A TI Active","metaDescription":"Texas Instruments TPS259470ARPWR electronic fuse in 10-VQFN-HR (2x2) package.
