Product details

Overview

SN7002NL6433HTMA1 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 / I_D = 0.17 A, and 0.2 A continuous drain current at T_A = 25 °C. It features dv/dt immunity up to 6 kV/µs and is AEC-Q101 qualified for automotive signal switching applications.

For engineers reviewing the SN7002NL6433HTMA1 datasheet, SN7002NL6433HTMA1 pinout, SN7002NL6433HTMA1 application, or SN7002NL6433HTMA1 equivalent, key selection factors include logic-level gate drive compatibility (V_GS(th) = 0.8–1.8 V), low R_DS(on) at 4.5 V, reverse diode recovery time (t_rr = 14.2–21.3 ns), and thermal resistance (R_thJA = 350 K/W).

Technical Context

This device operates as a single N-channel MOSFET with enhancement-mode gate control, optimized for low-voltage logic-compatible drive (V_GS = 4.5 V sufficient for full conduction). Its dv/dt rating of 6 kV/µs enables robust operation in inductive load switching without spurious turn-on.

It integrates a monolithic body diode with V_SD = 0.83–1.2 V at I_F = I_S, t_rr = 14.2–21.3 ns, and Q_rr = 5.9–8.8 nC - characteristics critical for flyback and freewheeling in compact DC-DC converters and LED drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	60 V - supports 24 V and 48 V rail switching with margin against transients
R_DS(on) @ 4.5 V	3.9–7.5 Ω - enables direct interface with 3.3 V/5 V microcontrollers without level shifters
I_D cont @ 25 °C	0.2 A - suitable for low-power load switching (e.g., sensors, LEDs, relays)
V_GS(th)	0.8–1.8 V - ensures reliable turn-on with standard logic outputs
t_rr	14.2–21.3 ns - limits switching losses and EMI in high-frequency (<1 MHz) PWM circuits
dv/dt immunity	6 kV/µs - prevents false triggering in noisy automotive environments
P_tot @ 25 °C	0.36 W - defines maximum power handling on minimal PCB footprint

Pinout & Package

SN7002NL6433HTMA1 uses the PG-SOT-23 (JEDEC TO-236AB) surface-mount package with 3 terminals: Gate (pin 1), Drain (pin 3), Source (pin 2). The marking "sSN" appears on the top surface.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Logic-level input controlling channel conduction; requires no external level shifter for 3.3 V/5 V MCU drive
Pin 2	Source	Reference node for gate drive and current return path; tied to system ground in low-side switch configuration
Pin 3	Drain	High-side connection to load; carries switched current and withstands 60 V transient voltage

Key Features

Feature	Design Value
Logic-level gate drive	V_GS(th) ≤ 1.8 V ensures full enhancement with 3.3 V GPIO, eliminating level-shifting circuitry
AEC-Q101 qualification	Validated for automotive temperature range (−55 °C to +150 °C) and reliability stress tests
dv/dt rated	6 kV/µs immunity prevents parasitic turn-on during fast voltage transients in motor or solenoid drives
Integrated body diode	V_SD = 0.83–1.2 V and t_rr = 14.2–21.3 ns support efficient freewheeling in buck and flyback topologies

Applications

IC Role / Device Role / Timing Role: Low-quiescent-load power gate with minimal standby loss.

Use Value: IGSS ≤ 10 nA at V_GS = 20 V ensures negligible gate leakage; P_tot = 0.36 W supports thermally constrained PCB layouts.

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-7-F	R_DS(on) = 3.5 Ω @ 10 V (vs. 2.5–5 Ω for SN7002N); V_GS(th) = 0.8–1.5 V; no AEC-Q101 qualification	Not rated for automotive use; lower R_DS(on) at 10 V but higher at 4.5 V	Prefer for cost-sensitive consumer designs where AEC-Q101 is unnecessary
DMN2004K-7	R_DS(on) = 2.8 Ω @ 4.5 V; V_GS(th) = 0.5–1.2 V; dv/dt not specified; no AEC-Q101	Higher gate sensitivity may increase noise susceptibility; lacks automotive validation	Choose when lowest possible R_DS(on) at 4.5 V is primary requirement and automotive compliance is not needed

Compared with BSS138W-7-F and DMN2004K-7, SN7002NL6433HTMA1 uniquely combines AEC-Q101 qualification, guaranteed dv/dt immunity, and stable R_DS(on) performance across −55 °C to +150 °C - making it the only option validated for safety-critical automotive signal switching.

FAQ

Is SN7002NL6433HTMA1 suitable for high-frequency PWM switching above 500 kHz?

Yes - its typical turn-off delay (t_d(off) = 5.3–8 ns), fall time (t_f = 3.6–5.4 ns), and low output capacitance (C_oss = 7.2–9.6 pF) support clean switching up to 1 MHz in low-duty-cycle applications. Thermal derating must be applied per the P_tot vs. T_A curve on page 4 of the datasheet.

What is the maximum safe operating voltage for SN7002NL6433HTMA1 in inductive load circuits?

The absolute maximum V_DS is 60 V, but in inductive switching (e.g., relay or solenoid drive), peak voltage spikes must remain below this limit. Its 6 kV/µs dv/dt rating helps suppress false turn-on, yet external clamping (e.g., TVS or RC snubber) is recommended when L·di/dt exceeds 30 V overshoot.

Does SN7002NL6433HTMA1 require a gate resistor for MCU-driven operation?

A gate resistor (typically 10–100 Ω) is recommended to damp ringing and limit peak gate current, especially when driven by fast GPIOs. While not strictly required for logic-level compatibility, it improves EMI performance and prevents potential gate oxide stress during hot-plug or noisy conditions.

Can SN7002NL6433HTMA1 replace BSS138 in existing designs?

Yes - pin-to-pin compatible in PG-SOT-23, with matching pinout (G-D-S). However, SN7002N offers higher V_DS (60 V vs. 50 V), AEC-Q101 qualification, and superior dv/dt immunity. Designers should verify layout thermal relief and confirm R_DS(on) meets load current requirements at actual V_GS and T_j.
