It targets isolated AC-DC converter designs where the primary-side MOSFET must withstand up to 800V — the breakdown rating covers the reflected voltage plus leakage spike on a universal-input flyback without an external clamp. ## Start-up and supply bias range Start-up threshold is 13V, and the Vcc operating range spans 11.5V to 23V. The 13V start-up allows the IC to begin switching before the auxiliary winding takes over, a common bias architecture in off-line flybacks. The wide Vcc range gives margin for the auxiliary winding voltage to vary with load. Output isolation is rated as isolated — the flyback transformer provides galvanic isolation between primary and secondary, meeting the safety isolation requirements of IEC 60950-1 and IEC 62368-1 for AC-DC power supplies. ## Industrial temperature range and package Operating junction temperature spans -25°C to 125°C, covering the industrial temperature band. The 16-SOIC package (0.154-inch body width, 3.90mm) is a standard surface-mount footprint for automated reflow assembly. Supplier device package is 16-SO. Supplied in Tape & Reel (TR) and Cut Tape (CT) options — the TR format suits volume pick-and-place; CT is available for prototype or low-volume builds. Product status is Active — STMicroelectronics continues to manufacture this part with no announced end-of-life. RoHS3 compliant for EU and global markets requiring restriction of hazardous substances. The ALTAIR05T-800TR is a standalone part in its family; BOM replacements would require a board-level evaluation.","metaTitle":"STMicroelectronics ALTAIR05T-800TR Flyback Controller, 800V","metaDescription":"Active STMicroelectronics ALTAIR05T-800TR offline flyback switch with 800V breakdown, integrated switch, isolated output, -25 to 125°C.
