| Pin No. | Symbol | Description | |---------|--------|-------------| | 1 | D (Drain) | Internal MOSFET drain – connected to transformer primary | | 2 | S (Source) | Internal MOSFET source – current sense point | | 3 | VCC | Supply voltage for the control IC (start-up and running) | | 4 | FB (Feedback) | Feedback input from secondary side (via optocoupler) | | 5 | GND | Ground reference for control circuit | The tab of the TO-220F package is internally connected to the Source (Pin 2). In many designs, the tab is isolated but may be used for heatsinking. Absolute Maximum Ratings (From Official STR F6267 Datasheet PDF) Caution: Stresses beyond these values may destroy the device.

A: The "H" variant typically has a lower RDS(on) and higher efficiency. Do not interchange without comparing the full datasheet. str f6267 datasheet pdf

A: Yes, Sanken provides datasheets in Japanese and often in English. Some aggregated sites offer translation notes. | Pin No

A: Not recommended. The maximum continuous drain current is 5.5A. For 150W (e.g., 19V/7.9A), the primary peak current would exceed safe margins. Consider STR-F6600 series. Conclusion The STR F6267 datasheet PDF is more than just a pinout diagram—it is an engineering toolkit that includes all necessary specifications for designing robust, high-efficiency flyback power supplies. By understanding the absolute maximum ratings, protection features, and typical application circuit, you can confidently integrate this IC into your next AC-DC converter project.
