Product details

Overview

VNS3NV04PTR-E from STMicroelectronics is a monolithic OMNIFET II fully autoprotected Power MOSFET fabricated in VIPower® M0-3 technology, designed as a rugged replacement for standard N-channel Power MOSFETs in DC–50 kHz switching applications. It features 120 mΩ R_DS(on), 3.5 A linear current limit, 40 V integrated overvoltage clamp, thermal shutdown at 170 °C typical, and diagnostic feedback via the input pin. It is used in automotive body control modules and industrial motor drivers requiring fault-tolerant load switching.

For engineers reviewing the VNS3NV04PTR-E datasheet, VNS3NV04PTR-E pinout, VNS3NV04PTR-E application, or VNS3NV04PTR-E equivalent, this page delivers verified electrical specs, validated protection behavior, confirmed SOT-223 package mapping, real-world fault feedback implementation details, and direct comparison with functionally aligned alternatives - all grounded in ST's production-grade documentation (Doc ID 15626 Rev. 5).

Technical Context

This device integrates gate driver, protection logic, and power stage into a single silicon die. Its linear current limiter operates independently of input voltage and maintains constant I_lim = 3.5 A (typ.) across -40°C to 150°C junction temperature, while the overtemperature shutdown triggers between 150°C and 200°C with automatic restart at ~135°C.

The input pin serves dual roles: it drives the internal gate (with 100 µA typical supply current) and provides fault indication by sinking up to 20 mA diagnostic current during thermal shutdown. The integrated clamp limits V_DS to 45 V (typ.) under inductive turn-off, enabling robust unclamped inductive load handling without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	120 mΩ @ V_IN = 5 V, I_D = 1.5 A, T_j = 25°C - enables low conduction loss in 12 V automotive loads drawing ≤3.5 A
I_lim	3.5 A (min) linear current limit - ensures predictable current limiting during overload without oscillation or latch-up
V_CLAMP	40 V (min) drain-source clamp voltage - protects against inductive kickback up to 40 V without external TVS
T_jsh	150–200°C thermal shutdown threshold - provides fail-safe cutoff before silicon degradation in sustained overload
I_gf	10–20 mA fault sink current - allows direct detection of thermal fault using simple pull-up resistor and MCU GPIO
IISS	100–150 µA input supply current - permits direct TTL/CMOS logic drive without external biasing
E_AS	100 mJ single-pulse avalanche energy - supports reliable operation under unclamped inductive switching stress

Pinout & Package

SOT-223 package: surface-mount, thermally enhanced 3-pin outline with exposed drain pad (pin 2) for improved heat dissipation. Pin 1 = INPUT, Pin 2 = DRAIN (connected to tab), Pin 3 = SOURCE.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (INPUT)	Gate control & fault feedback node	Accepts 0.5–5 V logic input; sinks 10–20 mA diagnostic current during thermal fault; draws only 100 µA in normal operation
Pin 2 (DRAIN)	Main power output terminal	Internally connected to exposed metal tab; handles up to 3.5 A continuous current; clamped to 40 V during inductive turn-off
Pin 3 (SOURCE)	Power return and reference ground	Provides low-impedance return path; referenced to system ground; used for current-sense feedback in some configurations

Key Features

Feature	Design Value
Linear current limitation	Maintains precise 3.5 A (min) current ceiling independent of V_IN or temperature - eliminates need for external current-sense amplifier and comparator loop
Integrated overvoltage clamp	40 V clamp threshold with 100 mJ avalanche rating - replaces discrete TVS diode in 12 V/24 V inductive load circuits
Thermal shutdown + auto-restart	Shuts down at 170°C (typ.), restarts at 135°C - prevents permanent damage during sustained overload while restoring function after cooling
Diagnostic feedback via input pin	Sinks 15 mA (typ.) fault current into input pin - enables zero-component fault signaling to microcontroller without optocoupler or extra IC
ESD robustness	4 kV HBM / 16.5 kV output-pin-only ESD rating - survives handling and board-level transients without additional protection

Equivalent & Alternatives

The following parts are listed as comparable options for similar protected Power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP3NK60ZFP	600 V, 3 A, no integrated protection - requires external current sense, thermal monitoring, and clamp	Used where higher voltage rating is needed but system-level protection is already implemented	Select when cost sensitivity outweighs integration benefit and board space allows discrete protection circuitry
IPS1021H	2.8 A current limit, 42 V clamp, same SOT-223 package - lower I_lim and tighter V_CLAMP tolerance	Targeted at lower-power 5 V logic-driven loads with stricter voltage margin requirements	Prefer for 5 V MCU interfaces needing tighter clamp control; avoid for 12 V/24 V loads demanding ≥3.5 A sustained current

Compared with STP3NK60ZFP, VNS3NV04PTR-E trades off voltage rating for full autonomy in protection and diagnostics; compared with IPS1021H, it delivers higher current capability and broader thermal margin - making it optimal for mid-power automotive and industrial DC switching where reliability trumps raw voltage headroom.

FAQ

What is the maximum continuous drain current for VNS3NV04PTR-E?

The device provides a guaranteed minimum linear current limit of 3.5 A under all operating conditions (V_IN = 5 V, V_DS = 13 V, -40°C ≤ T_j ≤ 150°C). Continuous operation at this level depends on PCB thermal design: with 50 mm² copper pour, it sustains 3.5 A at T_c = 25°C; derating applies above that case temperature per Figure 10 in the datasheet.

Can VNS3NV04PTR-E be driven directly by a 3.3 V microcontroller?

Yes - its input threshold voltage ranges from 0.5 V to 2.5 V, and it draws only 100–150 µA during normal operation. A 3.3 V GPIO can fully turn on the device and still provide sufficient margin to sink the 10–20 mA fault current during thermal shutdown, provided the series resistance is ≤220 Ω to maintain input voltage above 0.3 V under fault.

How does the diagnostic feedback work during thermal shutdown?

When junction temperature exceeds T_jsh (150–200°C), the device actively sinks 10–20 mA through the INPUT pin. If driven by a pull-up resistor (e.g., 10 kΩ to 5 V), this pulls the input voltage near 0 V - detectable as a logic-low fault signal. No external components are required beyond the pull-up, and the device resumes normal operation automatically once T_j falls below ~135°C.

Is an external freewheeling diode required when driving inductive loads?

No - the integrated source-drain diode has V_SD = 0.8 V at 1.5 A and t_rr = 107 ns, which is sufficient for most 12 V/24 V solenoid and relay applications. However, for high-dI/dt (>10 A/µs) or high-energy inductive loads, an external ultrafast diode may be added in parallel to reduce switching losses and improve reliability.
