OB25134JPA from OB On Bright Elec, in a SOIC-7. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply pin. Recommended operating range 5 V to 16 V; absolute max 20 V. UVLO(ON) ~3.7 V, UVLO(OFF) ~13 V, VDD_OVP ~18 V. |
| 2 | FB | input | Voltage feedback from the auxiliary winding. Connected to a resistor divider from the auxiliary winding that reflects the output voltage. Internal reference Vref_fb = 2.5 V. |
| 3 | NC | unconnected | No connection. Leave floating on the PCB. |
| 4 | CS | input | Current sense input. Connect to a sense resistor Rs from the BJT emitter path to program the peak primary current (Vth_ocp ~500 mV typical) and set CC output level. LEB time ~0.33 us. |
| 5 | C | output | HV BJT collector pin. Connects to the transformer primary winding. Pins 5 and 6 are tied internally to the collector of the integrated 800 V (Vcbo) power BJT; both should be connected together on the PCB for current and thermal handling. |
| 6 | C | output | HV BJT collector pin (paralleled with pin 5). Connect together with pin 5 to the transformer primary winding. |
| 7 | GND | power_in | Ground reference for the device. Also the emitter return of the internal HV BJT (through the CS sense resistor). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 512 faces against 132 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
