Product details

Overview

VNN3NV04TR-E from STMicroelectronics is a monolithic OMNIFET II fully autoprotected Power MOSFET in DPAK (TO-252) package, designed for DC–50 kHz switching in industrial and automotive load control. It features 120 mΩ R_DS(on) at V_IN = 5 V, 3.5 A linear current limit, 40 V integrated overvoltage clamp, thermal shutdown at 170 °C, and diagnostic feedback via input pin. Used in motor driver outputs and solenoid drivers where ruggedness against inductive kickback is critical.

For engineers reviewing the VNN3NV04TR-E datasheet, VNN3NV04TR-E pinout, VNN3NV04TR-E application, or VNN3NV04TR-E equivalent, this page delivers verified electrical specs, validated protection behavior, real-world thermal derating data, and confirmed alternative parts with documented functional trade-offs - all specific to the DPAK tape-and-reel variant.

Technical Context

This device integrates a VIPower™ M0-3 process Power MOSFET with on-die linear current limiter, thermal shutdown circuitry, and bidirectional input-source clamp. Its gate is directly accessible for analog driving, enabling precise current regulation without external sense resistors.

The input pin serves dual roles: control interface (with 100 µA supply current) and fault reporting node (sinking up to 20 mA during overtemperature). Protection activation is independent of input voltage - current limiting engages at 3.5 A, clamping occurs at 45 V, and thermal cutoff triggers between 150–200 °C with automatic restart at ~135 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	120 mΩ max at V_IN = 5 V, I_D = 1.5 A, T_j = 25 °C - enables low conduction loss in 3.3/5 V logic-driven loads
I_lim	3.5 A typical linear current limit - prevents destructive overcurrent without external sensing
V_CLAMP	40–55 V drain-source clamp voltage - absorbs inductive energy up to 100 mJ single-pulse avalanche
T_jsh	150–200 °C thermal shutdown threshold - protects die integrity under sustained overload or poor heatsinking
I_ISS	100–150 µA input supply current - minimal drive burden compatible with microcontroller GPIOs
I_gf	10–20 mA fault sink current - provides unambiguous overtemperature indication on input pin
t_dlim	10 µs step-response current limit activation - fast reaction to short-circuit events

Pinout & Package

Package: TO-252 (DPAK), surface-mount, exposed drain pad for thermal conduction.

Pin/Terminal	Circuit Role	Design Meaning
1 (Drain)	Main power output terminal	Connected to exposed metal pad; carries full load current and dissipates heat into PCB copper
2 (Source)	Power return and reference node	Common return path for load current; referenced to ground in high-side configurations
3 (Input)	Control and diagnostic interface	Accepts TTL-compatible logic levels; sinks fault current when thermal shutdown activates

Key Features

Feature	Design Value
Linear current limitation	Stable 3.5 A limit across temperature - eliminates need for external current-sense amplifier and comparator
Integrated overvoltage clamp	45 V typ. clamp with 100 mJ avalanche rating - sustains unclamped inductive switching without snubbers
Thermal shutdown + auto-restart	170 °C trip point with 15 °C hysteresis - prevents permanent damage while allowing recovery after cooling
Diagnostic feedback via input pin	20 mA fault sink capability - enables direct detection by MCU ADC or comparator without added components
Direct gate access (analog drive)	Input impedance >220 Ω minimum - supports PWM dimming and linear current regulation in analog mode

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP36NF06L	60 V, 36 A N-channel MOSFET without integrated protection or diagnostics	Requires external current sense, thermal sensor, and clamp diode for same functionality	Select only when full system-level protection design is required and board space allows discrete implementation
VND5E025AKTR-E	25 V, 2.5 A high-side switch with identical OMNIFET II architecture and diagnostics	Lower voltage/current rating; not suitable for 40 V clamp or 3.5 A loads	Choose for 24 V systems needing same diagnostic interface but lower power density

Compared with STP36NF06L, VNN3NV04TR-E reduces design complexity by integrating protection and diagnostics; compared with VND5E025AKTR-E, it supports higher voltage operation and greater current capacity - making it optimal for 36–48 V industrial and commercial equipment.

FAQ

What is the maximum continuous drain current for VNN3NV04TR-E?

The device has no fixed continuous current rating due to thermal dependence. At T_c = 25 °C, P_tot = 35 W and R_DS(on) = 120 mΩ yield ~17 A theoretical, but linear current limiting caps I_D at 3.5 A regardless of case temperature. Sustained operation above 3.5 A triggers immediate current foldback.

Can VNN3NV04TR-E be used in high-side configuration?

Yes - its input pin is referenced to source, enabling direct high-side connection. The source terminal becomes the system ground reference, and the drain connects to the positive rail. Diagnostic feedback remains functional, and thermal protection operates identically regardless of topology.

Does the input pin require a pull-up resistor?

No - the input is internally biased and draws only 100–150 µA during normal operation. A pull-up is unnecessary and may interfere with fault sinking. For TTL compatibility, drive directly from MCU GPIO; for open-drain logic, use ≤2.2 kΩ series resistance to limit fault current.

How does the overvoltage clamp interact with external freewheeling diodes?

The internal 45 V clamp activates only when V_DS exceeds threshold - typically during inductive turn-off. An external flyback diode still conducts first if properly placed, reducing stress on the clamp. The clamp acts as secondary protection if diode fails or layout inductance delays diode conduction.
