Pin	Signal	Direction	Function
1	S Source	Source	Return reference for the gate drive in a low-side circuit. The intrinsic body diode has its anode here.
2	G Gate	Gate	Insulated gate. Establish a defined voltage relative to S. Use a gate-to-source pull-down if the driver can float.
3	D Drain	Drain	Connect to the low side of the load in a low-side switch. The intrinsic body diode has its cathode here.

Signal assignments

Low-side switch

Drive G relative to S. A pull-down holds the gate near S when the drive is disconnected. Put a resistive load between its positive supply and D.

Intrinsic diode

The diode conducts from S toward D if D falls sufficiently below S. Swapping source and drain can leave the load conducting when the gate is low.

Parameter	Limit	Conditions and source
Drain–source voltage limit60 V	60 V	Absolute maximum for the listed onsemi parts. Check transient voltage and the safe operating area separately. onsemi NDS7002A/D Rev. 11 and onsemi 2N7000TA/D Rev. 1, p. 1
Continuous gate–source limit±20 V / ±30 V	±20 V / ±30 V	±20 V for 2N7000 and its D-code orders; ±30 V for 2N7000BU and 2N7000TA. Both figures are stress ratings. onsemi NDS7002A/D Rev. 11, p. 2; onsemi 2N7000TA/D Rev. 1, p. 1
Gate threshold at 1 mA0.8–3.0 V / 0.4–3.0 V	0.8–3.0 V / 0.4–3.0 V	VDS = VGS, 25 °C. The second range applies to 2N7000BU/TA. Use the specified on-resistance points to choose a gate drive for a load. onsemi NDS7002A/D Rev. 11, p. 2; onsemi 2N7000TA/D Rev. 1, p. 2
On-resistance at 10 V drive5 Ω maximum	5 Ω maximum	At ID = 500 mA under the specified electrical test conditions. The test current is separate from the 200 mA continuous maximum in the ratings. onsemi NDS7002A/D Rev. 11, pp. 2–3; onsemi 2N7000TA/D Rev. 1, pp. 1–2
On-resistance at 4.5 V drive5.3 Ω maximum	5.3 Ω maximum	At 75 mA and 25 °C for the standard 2N7000 in NDS7002A/D. Choose another part if you require a guaranteed on-resistance at 3.3 V. onsemi NDS7002A/D Rev. 11, p. 3
