Always cross-reference the datasheet tables before substituting.
Use a multimeter to check for a short circuit between Drain (Pin 1) and Source (Pin 2). Where to Download the STR-F6267 Datasheet PDF str f6267 datasheet pdf
Often utilized in higher-wattage power supplies but shares equivalent structural pin layouts. Below are the primary technical parameters compiled from
The datasheet includes several application notes that provide guidance on using the STR-F6267 in different applications. These notes cover topics such as: Overvoltage Protection (OVP)
Includes Overcurrent Protection (OCP), Overvoltage Protection (OVP), and Thermal Shutdown (TSD).
| Symptom | Likely cause per datasheet | Solution | |------------------------------|-----------------------------------------------------|--------------------------------------------| | No startup, VCC oscillates | VCC startup capacitor too small or leakage | Increase to 47µF, check startup resistor | | Supply shuts down under load | Current sense resistor too large (false OCP) | Reduce resistor value (e.g., 0.33Ω→0.27Ω) | | Blown IC | Drain overvoltage spike exceeding 650V | Improve snubber, check transformer leakage | | Intermittent restart | Overload protection triggered by noise on FB pin | Add 100pF capacitor from FB to GND |
The STR-F6267 is favored in heavy-duty consumer electronics repair due to its robust safety limits and high operating efficiency (up to 95%). Below are the primary technical parameters compiled from global database documentation like Alldatasheet :
