Product details

Overview

VNS3NV04DTR-E from STMicroelectronics is a dual-channel, fully autoprotected OMNIFET II Power MOSFET in SO-8 package, designed as a rugged replacement for standard power MOSFETs in DC–50 kHz switching applications. It features linear current limitation (3.5 A typ), integrated overvoltage clamp (40 V), thermal shutdown (150–200 °C), and diagnostic feedback via input pin. Used in industrial motor control, solenoid drivers, and automotive body electronics where fault resilience is critical.

For engineers reviewing the VNS3NV04DTR-E datasheet, VNS3NV04DTR-E pinout, VNS3NV04DTR-E application, or VNS3NV04DTR-E equivalent, this page delivers verified technical context, real-world protection behavior, SO-8 terminal mapping, design-meaningful specifications, and validated alternative options for high-reliability load switching.

Technical Context

The device integrates two independent OMNIFET II chips using ST's VIPower M0-3 technology, each with direct gate access for analog driving and low input current draw (100–150 µA). Its linear current limiter operates independently per channel, clamping drain current at 3.5 A (typ) regardless of input voltage, enabling predictable safe operation under overload.

Protection logic is fully monolithic: overvoltage clamp activates at 40 V (min), thermal shutdown triggers at 150–200 °C junction temperature, and fault status is signaled by sinking 10–20 mA through the INPUT pin during overtemperature events. All protections function without external components across –40 °C to 150 °C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on) (per ch.)	120 mΩ (typ) at V_IN = 5 V, I_D = 1.5 A, T_j = 25 °C - enables low conduction loss in 12 V/24 V industrial loads
Current limit (I_LIMH)	3.5 A (typ) - provides repeatable short-circuit current limiting without external sensing
Drain-source clamp voltage	40 V (min) - protects against inductive kickback up to 40 V without external TVS
Thermal shutdown threshold	150–200 °C (T_jsh) - shuts down before silicon damage; auto-restarts at ~135 °C
Input supply current	100–150 µA (I_ISS) - allows direct TTL-level drive without buffer stage
Fault sink current	10–20 mA (I_gf) - delivers unambiguous diagnostic signal to microcontroller GPIO
ESD rating	4 kV HBM (input), 16.5 kV CDM (output) - exceeds IEC 61000-4-2 Level 4 for board-level robustness

Pinout & Package

SO-8 package (ECOPACK® compliant, lead-free, JEDEC MS-012AC); 1.27 mm pitch; 4.9 mm × 6.0 mm body; 1.75 mm height. Dual-channel layout with shared source terminals and independent inputs/drains.

Pin/Terminal	Circuit Role	Design Meaning
1 (INPUT1)	Channel 1 gate control & fault feedback	Accepts 0–5 V TTL logic; sinks 10–20 mA during overtemperature fault
2 (SOURCE1)	Channel 1 source reference	Common return for Channel 1 load; electrically isolated from Channel 2 source
3 (DRAIN1)	Channel 1 high-side switch output	Rated for 40 V clamp; handles up to 3.5 A limited current
4 (DRAIN2)	Channel 2 high-side switch output	Independent of Channel 1; identical clamp and current-limit specs
5 (SOURCE2)	Channel 2 source reference	Common return for Channel 2 load; separate from SOURCE1
6 (INPUT2)	Channel 2 gate control & fault feedback	Functionally identical to Pin 1; supports dual independent control
7, 8 (GND)	Power ground / heat sink pad	Internally connected to both sources; primary thermal path to PCB copper

Key Features

Feature	Design Value
Linear current limitation	Clamps I_D at 3.5 A (typ) per channel - eliminates need for external current-sense resistors and comparators
Integrated overvoltage clamp	40 V min clamp voltage - absorbs inductive energy without external snubber diodes in 24 V systems
Thermal shutdown + auto-restart	Shuts down at 150–200 °C; restarts at ~135 °C - enables self-recovery after transient overloads
Diagnostic feedback via input pin	Sinks 10–20 mA fault current - directly interfaces with MCU GPIO for real-time health monitoring
Direct analog gate driving	0–5 V compatible input with 100–150 µA draw - supports PWM dimming and linear regulation without level shifters

Applications

Industrial Solenoid Control

Automotive Body Electronics

Use Scenario: Driving 12 V/24 V DC solenoids in PLC I/O modules with frequent on/off cycling and inductive kickback.

IC Role / Device Role / Timing Role: High-side load switch with built-in clamp and current limiting - replaces discrete MOSFET + TVS + sense resistor + comparator.

Use Value: Eliminates 4–6 external components per channel while maintaining 3.5 A safe current limit and 40 V transient suppression.

Use Scenario: Controlling door locks, seat adjusters, and mirror actuators in automotive body control modules (BCM).

IC Role / Device Role / Timing Role: Fault-tolerant power switch with diagnostic feedback - reports thermal faults to BCM microcontroller via same input line used for control.

Use Value: Reduces BOM count and improves ASIL-B readiness via integrated overtemperature detection and ESD-hardened I/O.

DC Motor Starter Circuits

Heating Element Drivers

Use Scenario: Starting brushed DC motors in HVAC blowers and industrial fans where stall currents exceed rated MOSFET limits.

IC Role / Device Role / Timing Role: Current-limited high-side driver - sustains 3.5 A indefinitely during startup, then transitions to normal switching once motor spins.

Use Value: Prevents MOSFET destruction during 5–10× stall current events without requiring complex current-loop control firmware.

Use Scenario: Switching resistive heating elements in smart thermostats and appliance control boards with tight thermal margins.

IC Role / Device Role / Timing Role: Thermally protected load switch - shuts down before PCB trace overheating or connector degradation occurs.

Use Value: Enables Class II insulation compliance by limiting junction temperature to ≤200 °C even under sustained overload.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-channel protected high-side switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Single-channel, 3.5 A current limit, integrated current sense output (not diagnostic feedback)	No dual-channel integration; requires two devices for same functionality; lacks input-pin fault sinking	Choose when needing analog current monitoring instead of digital fault signaling
TPS27082L	Single-channel, 4 A current limit, no integrated clamp, 60 V abs max rating, open-drain FAULT pin	Requires external TVS for inductive loads; FAULT pin is dedicated (not shared with input); higher R_DS(on) (180 mΩ)	Prefer for 3.3 V logic systems with lower thermal budget and no clamp requirement

Compared with VNS3NV04DTR-E, STSPIN250 offers current measurement but no dual-channel integration or input-pin diagnostics, while TPS27082L provides higher voltage margin and dedicated fault signaling but demands external protection and delivers higher conduction loss.

FAQ

Is VNS3NV04DTR-E still in active production?

No - STMicroelectronics has marked VNS3NV04DTR-E as obsolete (as confirmed in Rev 3, September 2013 datasheet). However, Aetrix Electronics maintains legacy inventory with full traceability and offers engineering support for drop-in replacements and migration paths to active alternatives like VNQ5E050AKTR-E.

Can VNS3NV04DTR-E drive inductive loads without external flyback diodes?

Yes - its integrated 40 V drain-source clamp (V_CLAMP) safely absorbs energy from inductive loads up to 40 V. For loads generating >40 V transients (e.g., >24 V systems with long cables), an external TVS remains recommended to prevent clamp saturation and thermal runaway.

How does the diagnostic feedback work during overtemperature events?

When junction temperature exceeds 150–200 °C, the device sinks 10–20 mA (I_gf) through the INPUT pin. If driven by a low-impedance source (e.g., MCU GPIO with <1 kΩ series resistance), this pulls the input voltage low - detectable as a logic-low fault flag. High-impedance drivers see the pin fall to 0 V without affecting switching behavior.

What is the maximum continuous drain current per channel?

The device does not specify a continuous I_D rating due to thermal dependence. Under typical SO-8 PCB layout (50 mm² copper), R_thj-amb = 80 °C/W limits usable continuous current to ~1.5 A at 25 °C ambient. At 70 °C ambient, derated continuous current drops to ~0.9 A - always constrained by thermal shutdown activation at 150–200 °C junction temperature.
