KP107ALSPA from Kiwi Instruments, in a SOP-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	GND	power_in	Chip reference ground.
2	ROVP	input	Output over-voltage protection setting pin and enable input. Connect a resistor (>6kΩ recommended) to GND to program the OVP threshold; if left floating, OVP is disabled. Tying this pin to GND (V_ROVP < 150mV) disables/shuts down the IC. Sources I_ROVP ≈ 49μA.
3	NC	unconnected	Non-functional pin. Leave floating in the application.
4	HVDD	power_in	High-voltage supply pin for the chip. Absolute max 650V; startup threshold HVDD_ON ≈ 11.5V typ, shutdown HVDD_OFF ≈ 6.6V typ. HV charging current ~10mA at HVDD=20V; leakage 10-60μA.
5	Drain	passive	Drain of the internal 500V power MOSFET. Pins 5 and 6 are tied together internally to the same drain node. Rdson typ 12Ω for KP107AL variant.
6	Drain	passive	Drain of the internal 500V power MOSFET. Pins 5 and 6 are tied together internally to the same drain node.
7	CS	input	Current-sense input pin for the MOSFET source current. Peak-current reference V_cs(max) ≈ 600mV typ; leading-edge blanking T_LEB ≈ 500ns; over-current shutdown delay T_D_OC ≈ 100ns.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`kp107alspa.step`	111 KB	You want the bare part, or you mark your own boards.
`kp107alspa-etched.step`	1.7 MB	You want the part with `KP107ALSPA` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 440 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.
