Product details
Overview
2N7002-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 60V V(BR)DSS, 7.5Ω RDS(ON) @ VGS = 5V, and 210mA ID max at TA = +25°C. It delivers low gate threshold voltage (1.0–2.5V), fast switching (tD(on) = 2.8ns), and low input capacitance (Ciss = 22pF), making it suitable for compact DC-DC converter high-side switches and load switching in portable power management.
For engineers reviewing the 2N7002-7 datasheet, 2N7002-7 pinout, 2N7002-7 application, or 2N7002-7 equivalent, key selection criteria include verified RDS(ON) at 5V drive, thermal resistance (RθJA = 241°C/W on 1"×1" 2oz Cu), body diode forward voltage (VSD = 0.78V), and AEC-Q101 qualification status for automotive-grade reliability assessment.
Technical Context
This discrete MOSFET operates as a voltage-controlled unidirectional switch with enhancement-mode turn-on behavior requiring positive VGS above threshold. Its low RDS(ON) and fast tD(off) = 7.6ns support efficient pulse-width modulation in battery-powered logic-level driven circuits.
The device integrates a monolithic silicon die with integrated body diode (VSD = 0.78V @ IS = 115mA), optimized for bidirectional current handling in flyback and reverse-polarity protection topologies. Gate drive compatibility with 3.3V/5V microcontrollers is ensured by VGS(th) ≤ 2.5V and low Qgs = 82pC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 60V - Maximum drain-source blocking voltage before avalanche conduction; enables use in 24V industrial bus and 36V automotive subsystems. |
| RDS(ON) max | 7.5Ω @ VGS = 5V - Confirmed on-resistance at standard logic-level drive; determines I²R loss in 210mA continuous load switching. |
| ID max | 210mA @ TA = +25°C - Continuous drain current rating under defined PCB thermal conditions; sets upper bound for steady-state load capability. |
| Qg total | 223pC - Total gate charge required for full turn-on; directly impacts switching loss and driver strength requirements in PWM operation. |
| tD(off) | 7.6ns - Turn-off delay time measured at VDD = 30V, ID = 0.2A; critical for minimizing shoot-through risk in half-bridge configurations. |
| VGS(th) | 1.0–2.5V - Gate threshold voltage range; ensures reliable turn-on with 3.3V GPIO and eliminates need for level-shifting in low-voltage MCU interfaces. |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with 3-pin configuration, 0.008g mass, UL 94V-0 flammability rating, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for channel conduction | Connected to ground or low-side reference; forms common node with body diode cathode for synchronous rectification. |
| 2 (Gate) | Control electrode for channel formation | Receives logic-level voltage to modulate RDS(ON); requires <223pC charge for full enhancement; sensitive to ESD (±20V VGSS rating). |
| 3 (Drain) | High-side current entry point | Connects to load or supply rail; sustains 60V blocking; hosts integrated body diode anode for freewheeling current paths. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 5V drive | 7.5Ω enables <0.83mW conduction loss at 100mA, reducing thermal stress in space-constrained PCB layouts. |
| Fast switching speed | 7.6ns tD(off) and 5.6ns tf minimize transition losses in >1MHz DC-DC controllers without external gate drivers. |
| AEC-Q101 qualified | Validated for automotive applications including body control modules and infotainment power sequencing per stress test requirements. |
| Green RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets EU ELV and China RoHS environmental mandates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004K-7 | RDS(ON) = 3.5Ω @ VGS = 4.5V; higher ID = 600mA; SOT23-3 package identical. | Higher current capability supports larger loads but increases gate charge (Qg = 520pC), demanding stronger drive. | Select when >210mA load current or lower conduction loss is required; verify driver can source 520pC within timing budget. |
| BSS138-7-F | RDS(ON) = 3.5Ω @ VGS = 10V only; VGS(th) = 0.8–1.5V; same SOT23 footprint. | Lower VGS(th) improves 1.8V logic compatibility but RDS(ON) degrades significantly below 4.5V drive. | Prefer for ultra-low-voltage systems (1.8V–2.5V MCU); avoid in 3.3V-only designs where RDS(ON) exceeds 10Ω. |
Compared with DMN2004K-7 and BSS138-7-F, the 2N7002-7 offers balanced trade-offs: moderate RDS(ON) at 5V, minimal Qg for weak-drive MCUs, and AEC-Q101 validation-making it optimal for cost-sensitive, thermally constrained 3.3V automotive and industrial load switches.

FAQ
What is the maximum junction temperature for continuous operation?
The 2N7002-7 has an operating junction temperature range of –55°C to +150°C. For continuous operation at rated ID = 210mA, thermal design must ensure TJ remains ≤150°C-achievable with RθJA = 241°C/W on a 1"×1" 2oz Cu PCB, limiting ambient temperature to ≤85°C under full load.
Is the 2N7002-7 suitable for 3.3V microcontroller GPIO drive?
Yes-the 2N7002-7's VGS(th) range of 1.0–2.5V guarantees turn-on with 3.3V logic, and its RDS(ON) = 7.5Ω at VGS = 5V implies sub-10Ω performance at 3.3V (per Fig. 4). Measured data shows RDS(ON) ≈ 9.2Ω at VGS = 3.3V, sufficient for ≤150mA loads with <2mW conduction loss.
Does the 2N7002-7 include integrated ESD protection?
No-the 2N7002-7 lacks on-die ESD protection circuitry. Its absolute maximum VGSS rating is ±20V, and gate oxide is susceptible to damage from static discharge. External TVS diodes or series resistors (≥100Ω) are recommended in handling and PCB layout to prevent gate rupture during assembly or field operation.
How does the body diode affect reverse-current blocking in high-side configuration?
In high-side switch configuration, the intrinsic body diode conducts when VS > VD, allowing reverse current flow unless actively blocked. To prevent backfeeding, the 2N7002-7 must be used with external circuitry (e.g., series Schottky or second MOSFET) or operated only in unidirectional load-switching mode where reverse voltage is clamped or absent.
