Published: [Current Date]

Reading Time: 3 minutes

If you repair LCD TVs, power adapters, or industrial SMPS units, you are likely very familiar with the Sanken STR-F6267. This offline flyback regulator IC is a workhorse, but finding the correct and up-to-date technical documentation for it has always been a bit of a headache—until now.

We are happy to report that a revised and updated version of the STR-F6267 Datasheet (PDF) has just been released.

Here is what has changed in the new revision and why you need to download this version before your next repair job.

Verification checklist when you obtain a PDF

• Confirm manufacturer name and logo match expected vendor.
• Check document revision date/version and changelog.
• Validate absolute maximum ratings and protection thresholds against your design margins.
• Review typical application circuit and recommended component values.
• Ensure package mechanical drawing matches the part in hand.

Final Verdict

The STR-F6267 remains a reliable choice for flyback designs under 80W. However, do not rely on a decade-old printout. Always download the updated PDF from Allegro or a verified distributor to get the latest thermal derating curves and PCB layout guidelines.

Pro Tip: Look for the "Rev. 2.0" watermark on your datasheet. If it isn't there, you are looking at obsolete data that might leave your transformer humming and your FET blowing.

STR-F6267 SANKEN Discrete Semiconductors - Jotrin Electronics

The STR-F6267 is an offline switching regulator IC manufactured by Sanken. It is widely used in flyback converter power supplies for televisions and monitors because it integrates a high-voltage power MOSFET and a controller chip in a single package.  Quick Technical Specs  Manufacturer: Sanken Electric Co., Ltd. [3, 4] Package Type: TO-3P-5 (5-pin) or ZIP package [3, 4]

Function: Off-line SMPS (Switching Mode Power Supply) Primary IC [3] Key Features: Internal high-voltage avalanche-guaranteed MOSFET. Built-in Pulse Width Modulation (PWM) control.

Protection features: Overcurrent, Overvoltage, and Thermal shutdown.  Pinout Configuration 

The STR-F6267 typically uses a 5-pin layout. Understanding these pins is crucial for troubleshooting power supply failures:  Pin #  Description 1 Drain

MOSFET Drain; connects to the primary winding of the transformer. 2 Source

MOSFET Source; usually connects to ground via a current-sensing resistor. 3 Ground Control circuit ground. 4 VCC

Power supply for the internal control circuit (startup voltage). 5 Feedback

Regulation input; receives error signal from the optocoupler. Deep Troubleshooting Guide 

If you are repairing a device using the STR-F6267, follow these common diagnostic steps: 

Check Pin 4 (VCC): If the chip won't start, check the startup resistor connected to Pin 4. You should see a rising voltage (typically around 16V–18V) before the chip kicks in.

Inspect the "Source" Resistor: The small-ohm resistor connected to Pin 2 often blows if the MOSFET shorts. If this resistor is open, the IC is likely dead.

MOSFET Test: Use a multimeter to check for a short between Pin 1 (Drain) and Pin 2 (Source). A short here indicates internal catastrophic failure.

Secondary Side: If the IC is "pulsing" (voltage on VCC keeps rising and falling), check for a shorted diode on the secondary side of the power supply.  Technical Resources

5. Protection Features

1. Overcurrent Protection (OCP)

   • Pulse‑by‑pulse limiting using S pin voltage.
   • If OCP persists for a set period → auto restart (hiccup mode).

2. Overload Protection (OLP)

   • Monitored via FB pin voltage.
   • FB > threshold for longer than tOLP → latch/restart.

3. Overvoltage Protection (OVP)

   • On VCC pin. Shuts down when VCC > ~27.5V.

4. Thermal Shutdown (TSD)

   • Prevents overheating. Auto recovery with hysteresis.

3. Protection Latch Mode Table

The updated document clarifies which faults cause auto-restart vs latch-off. Overload (OLP) triggers auto-restart (1 second hiccup), while OVP on VCC triggers a full latch (requires AC power cycling).
