These are both reputable component sourcing platforms that reference the STR-F6267 and indicate the availability of technical documentation. For the most accurate specifications, always refer to the official datasheet from such sources or the manufacturer. str f6267 datasheet pdf upd

: Drain / Startup terminal (MOSFET drain and input for start-up signal). Typical Applications

Includes a power MOSFET and a current-mode PWM controller. Operating Temperature: Reliable performance up to 105°C . Efficiency: Can achieve high efficiency levels (up to 95% ). Key Features & Protections

You may encounter variants like STRF6267D(RP) . The "D" often denotes a different or newer revision, and "(RP)" typically indicates tape and reel (embossed) packaging for automated assembly. While electrical characteristics are largely identical, always consult the specific datasheet for the variant you are using.

When AC main power is applied, voltage feeds through a startup resistor to charge an external capacitor connected to the pin. Once the voltage hits the start-up threshold ( The robust current handling capabilities of the STR-F6267

| Symptom | Likely Cause | Datasheet Check Point | Solution | |---------|--------------|------------------------|-----------| | VCC cycles between 8V and 15V | Startup circuit fails or OLP (Overload) triggered | Check UVLO on/off thresholds (typically 15V on, 8.5V off) | Replace startup resistor or check secondary short | | No output, drain pin shows 320V but IC not switching | VCC pin voltage <15V | Measure VCC pin voltage during operation | Auxiliary winding may be open | | IC heats up rapidly | Overcurrent or MOSFET Rds(on) degradation | Check OCP threshold voltage (0.7V typical) | Replace current sense resistor (0.47Ω) | | Random shutdown under load | Thermal shutdown (TSD) activated | TSD temperature >140°C (from datasheet) | Improve heatsinking or reduce ambient temperature |
