PT7M3808G01TAEX from Diodes Incorporated, in a SOT-23-6. 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	RESET	output	Active-low, open-drain RESET output. Driven to a low-impedance state when reset is asserted and remains asserted for the programmed delay after both SENSE rises above VIT and MR returns high. Requires an external pull-up (10kΩ to 1MΩ); the pull-up may be tied to a rail higher than VDD (up to 6.5V). Guaranteed VOL 0.3V @ IOL=0.4mA (1.3V<=VDD<1.8V) or 0.4V @ IOL=1.0mA (1.8V<=VDD<=6.5V); leakage <=300nA when not asserted.
2	GND	power_in	Device ground reference (0 V).
3	MR	input	Active-low manual reset input. Driving MR below 0.3VDD asserts RESET; MR must return above 0.7VDD to clear. Internally pulled up to VDD by a ~90kΩ (70k min) resistor, so the pin can be left floating if unused. Do not apply voltage above VDD.
4	CT	passive	Reset-delay programming pin. Three modes: (a) leave open -> fixed 20ms delay; (b) tie to VDD through 40k-200kΩ -> fixed 300ms delay; (c) tie an external capacitor (>=100pF) from CT to GND -> user-programmable delay 1.25ms-10s per CT(nF)=[tD(s)-0.5e-3]x175. Charged by an internal 220nA source to 1.23V. Absolute range -0.3V to VDD+0.5V; use low-leakage (ceramic) capacitors.
5	SENSE	input	Voltage-monitor input. RESET asserts when SENSE drops below the negative-going threshold VIT (0.405V typ on the G01 adjustable variant); the comparator has ~1.5% VIT hysteresis. Input current ±25nA max on G01. Recommended to add a 1nF-10nF bypass capacitor for noise immunity. Absolute range -0.3V to +7V.
6	VDD	power_in	Supply voltage, 1.7V to 6.5V (absolute max 7.0V). Typical quiescent current ~2.8µA at 3.3V. Place a 0.1µF ceramic decoupling capacitor close to this pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`pt7m3808g01taex.step`	97 KB	You want the bare part, or you mark your own boards.
`pt7m3808g01taex-etched.step`	2.7 MB	You want the part with `PT7M3808G01TAEX` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 667 faces against 117 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.
