AP3301K6TR-G1

Diodes Incorporated · AC-DC Controllers & Regulators · SOT-26

AP3301K6TR-G1 from Diodes Incorporated, in a SOT-26. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Signal ground and current return for the driver and control circuits.
2 FB input Feedback input connected directly to the opto-coupler, with 15-25 kΩ input impedance and a 4.5V typical over-load protection threshold.
3 DEM input Valley detection for QR control (75mV threshold), AC line voltage detection for brown-in/brown-out trigger current, and SOVP sensing (3.8V typical threshold).
4 SENSE input Current sense input with 0.88V typical maximum sense voltage and 1.8V typical FOCP threshold; input range -0.3 to 7V.
5 VCC power_in Supply voltage for the driver and control circuits, with a 10 to 25V recommended range, 30V absolute maximum, and 15.8V typical startup voltage.
6 GATE output Gate driver output with 13V typical clamping voltage and 350mA maximum output current.
