Product details

Overview

SN7002N from Infineon Technologies is an N-channel enhancement-mode logic-level SIPMOS small-signal transistor in PG-SOT-23 package, rated for 60 V V_DS, 5 Ω R_DS(on) at V_GS = 4.5 V, and 0.2 A continuous drain current; used in low-power load switching, LED drivers, and level-shifted gate control in automotive body electronics.

For engineers reviewing the SN7002N datasheet, SN7002N pinout, SN7002N application, or SN7002N equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = 0.8–1.8 V), dv/dt ruggedness (6 kV/µs), AEC-Q101 qualification, and SOT-23 thermal resistance (R_thJA = 350 K/W).

Technical Context

This discrete MOSFET operates in enhancement mode with a threshold voltage range of 0.8–1.8 V, enabling direct interface with 3.3 V and 5 V logic controllers without gate boosting. Its 60 V breakdown voltage and 0.2 A continuous ID support low-voltage DC distribution in space-constrained modules.

The device integrates a monolithic body diode with 0.83–1.2 V forward voltage and 14.2–21.3 ns reverse recovery time, suitable for freewheeling in inductive loads like solenoids and relays where fast commutation and low Q_rr (5.9–8.8 nC) reduce switching loss.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 24 V automotive and industrial bus systems with margin against transients
R_DS(on) @ V_GS = 4.5 V	3.9–7.5 Ω - enables logic-level drive from microcontrollers and FPGA I/O banks
I_D (continuous)	0.2 A @ T_A = 25 °C - suitable for signal-level switching and bias control circuits
dv/dt rating	6 kV/µs - ensures robustness against fast voltage transients in noisy environments
V_GS(th)	0.8–1.8 V - guarantees turn-on with standard 3.3 V logic outputs
Q_g	1–1.5 nC @ V_GS = 0–10 V - minimizes gate drive power in high-frequency PWM applications
T_j range	−55 to +150 °C - qualified per AEC-Q101 for under-hood automotive use

Pinout & Package

SN7002N uses the PG-SOT-23 (JEDEC TO-236AB) package with standardized 3-pin layout and 1.3 mm × 2.9 mm footprint. Thermal performance is optimized for minimal PCB copper area (R_thJA = 350 K/W at minimal footprint).

Applications

Automotive Interior Lighting

Industrial Sensor Interface

Use Scenario: Switching 12 V LED strips in door panels and footwells using CAN/LIN-controlled MCU outputs.

IC Role / Device Role / Timing Role: Low-side load switch controlled by 3.3 V GPIO with fast turn-on (t_d(on) ≤ 3.6 ns) and low conduction loss.

Use Value: Eliminates need for external level shifters; R_DS(on) ≤ 7.5 Ω limits I²R heating at 0.2 A.

Use Scenario: Enabling/disabling analog sensor supply rails (e.g., pressure or temperature sensors) in programmable logic controllers.

IC Role / Device Role / Timing Role: Precision on/off control of 5–24 V bias rails with minimal leakage (I_DSS ≤ 0.1 µA at 25 °C).

Use Value: Ensures rail isolation during sleep modes; V_GS(th) stability over −40 to +125 °C maintains reliable turn-off.

Low-Power Relay Driver

USB-C Port Power Switch

Use Scenario: Driving 5 V/12 V electromagnetic relays in HVAC control modules where inductive kick must be clamped.

IC Role / Device Role / Timing Role: Active freewheeling switch using integrated body diode with t_rr ≤ 21.3 ns and Q_rr ≤ 8.8 nC.

Use Value: Reduces voltage overshoot across relay coil; dv/dt rating prevents false triggering during coil de-energization.

Use Scenario: Controlling V_BUS enable on USB-C downstream ports in portable docking stations.

IC Role / Device Role / Timing Role: High-side or low-side power path switch with logic-compatible gate and low quiescent current (I_GSS ≤ 10 nA).

Use Value: Supports USB PD compliance via precise on-resistance control (R_DS(on) typ. 3.9 Ω @ 4.5 V) and thermal safety margin.

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
BSS138W from Diodes Inc.	V_DS = 50 V, R_DS(on) = 3.5 Ω @ 4.5 V, I_D = 0.22 A, no AEC-Q101 qualification	Limited to non-automotive consumer/industrial use due to missing automotive reliability validation	Prefer when cost sensitivity outweighs automotive qualification requirements
NX7002AK from Nexperia	V_DS = 60 V, R_DS(on) = 4.5 Ω @ 4.5 V, I_D = 0.3 A, AEC-Q101 qualified, same SOT-23 package	Higher current rating allows margin in thermally constrained layouts	Select when higher continuous current headroom (0.3 A vs. 0.2 A) is required without changing PCB footprint

Compared with BSS138W and NX7002AK, SN7002N offers tighter V_GS(th) distribution (0.8–1.8 V), superior dv/dt immunity (6 kV/µs), and identical AEC-Q101 compliance to NX7002AK-making it optimal for noise-prone automotive domains requiring predictable turn-on behavior.

FAQ

Is SN7002N suitable for 3.3 V microcontroller gate drive?

Yes. With a guaranteed gate threshold voltage of 0.8–1.8 V and full enhancement at V_GS ≥ 4.5 V, SN7002N switches reliably using standard 3.3 V GPIO outputs. Its R_DS(on) remains below 7.5 Ω at 4.5 V, ensuring low conduction loss without external level shifting.

What is the maximum safe operating temperature for continuous operation?

The junction temperature must not exceed +150 °C. At ambient temperatures up to +70 °C, the device supports 0.16 A continuous drain current. Derating follows the published P_tot vs. T_A curve (Page 4), with R_thJA = 350 K/W limiting power dissipation to 0.36 W at T_A = 25 °C.

Does SN7002N have an integrated body diode, and what are its characteristics?

Yes. It features a monolithic parasitic body diode with forward voltage of 0.83–1.2 V at I_F = I_S, reverse recovery time of 14.2–21.3 ns, and Q_rr of 5.9–8.8 nC. These values are measured at V_R = 30 V, dI_F/dt = 100 A/µs, and support freewheeling in inductive loads without external diodes.

How does the dv/dt rating impact real-world circuit design?

The 6 kV/µs dv/dt rating means SN7002N resists false turn-on during rapid voltage transients-critical in automotive wiring harnesses exposed to load-dump or inductive kick events. This eliminates need for external gate resistors or RC snubbers in many 12/24 V systems, simplifying layout and improving reliability.
