Product details
Overview
VNS3NV04D-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), thermal shutdown (150–200 °C), and integrated 40 V drain-source clamp. Used in automotive body control modules and industrial motor drivers where fault resilience and diagnostic feedback are critical.
For engineers reviewing the VNS3NV04D-E datasheet, VNS3NV04D-E pinout, VNS3NV04D-E application, or VNS3NV04D-E equivalent, this page delivers verified electrical specs, SO-8 terminal mapping, protection behavior under overload/overtemperature, and real-world use cases in load switching with diagnostics.
Technical Context
The device integrates two monolithic VIPower M0-3 OMNIFET II chips in one SO-8 package, each with independent input-driven gate control, internal linear current limiter, overvoltage clamp, and thermal sensing. Its analog gate drive enables direct TTL-level compatibility without external level-shifting.
Protection logic operates autonomously: overtemperature shutdown triggers at 150–200 °C junction temperature and resets at ~135 °C; fault status is communicated via sink current (10–20 mA) on the INPUT pin during thermal fault, enabling host MCU detection without additional sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) per channel | 120 mΩ (typ) at VIN = 5 V, ID = 1.5 A, Tj = 25 °C - defines conduction loss in low-side switch configuration |
| Current limit (ILIM) | 3.5 A (typ) at VIN = 5 V, VDS = 13 V - provides predictable short-circuit current ceiling without external sense resistor |
| Drain-source clamp voltage | 40 V (min) - protects against inductive kickback up to rated energy (100 mJ single-pulse avalanche) |
| Input supply current (IISS) | 100–150 µA at VIN = 5 V - enables low-power control interface with minimal bias draw |
| Fault sink current (IGF) | 10–20 mA during thermal shutdown - allows direct detection of fault state by monitoring input pin voltage drop |
| ESD rating (HBM) | 4 kV - meets automotive-grade robustness requirements for board-level handling |
| Switching frequency range | DC to 50 kHz - supports PWM-controlled resistive and inductive loads without derating |
Pinout & Package
SO-8 package (ECOPACK®, lead-free, RoHS-compliant); 1.27 mm pitch; 4.9 mm × 6.0 mm body; thermal resistance Rthj-lead = 30 °C/W per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (INPUT1) | Channel 1 gate control & fault feedback | Accepts TTL-compatible input; sinks 10–20 mA during thermal fault to signal shutdown |
| 2 (SOURCE1) | Channel 1 source reference | Common return for channel 1 load; tied internally to power ground path |
| 3 (DRAIN1) | Channel 1 high-current output | Connects to switched load; handles up to 3.5 A limited current with 40 V clamp |
| 4 (DRAIN2) | Channel 2 high-current output | Independent high-side or low-side output; shares same protection architecture as DRAIN1 |
| 5 (SOURCE2) | Channel 2 source reference | Separate return for channel 2; enables dual independent load control |
| 6 (INPUT2) | Channel 2 gate control & fault feedback | Functionally identical to INPUT1; supports synchronous or independent channel operation |
| 7, 8 (GND) | Power ground connection | Internally connected to both SOURCE pins; must be low-inductance PCB plane for thermal and EMI performance |
Key Features
| Feature | Design Value |
|---|---|
| Linear current limitation | Clamps ID to 3.5 A (typ) regardless of VIN, preventing destructive runaway during short circuits |
| Integrated overvoltage clamp | 40 V min clamp voltage with 100 mJ single-pulse avalanche energy rating - eliminates need for external TVS in many inductive drive designs |
| Thermal shutdown with auto-restart | Shuts down at 150–200 °C; restarts automatically when Tj drops ~15 °C below trip point - enables self-recovering system behavior |
| Diagnostic feedback via INPUT pin | Active sink current (10–20 mA) on INPUT pin during fault - enables MCU-level fault logging without extra pins or components |
| Direct analog gate drive | Operates with 0.5–6 V input voltage range; compatible with 3.3 V and 5 V logic - removes need for gate driver ICs in cost-sensitive designs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel protected power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN250 | Single-channel, integrated current regulation + microstepping; no thermal shutdown or clamp; 1.8 A max continuous | Targeted at stepper motor control, not general-purpose load switching | Choose only if microstepping or integrated driver logic is required - lacks VNS3NV04D-E's dual-channel autonomy and ruggedness |
| IPS1021H | Single-channel high-side switch; 2.5 A current limit; 42 V clamp; no linear current limiting (only foldback) | Designed for high-side automotive loads; no dual-channel integration | Select when high-side topology and AEC-Q100 qualification are mandatory - sacrifices channel count and linear limiting behavior |
Compared with STSPIN250 and IPS1021H, the VNS3NV04D-E uniquely combines dual independent channels, linear current limiting, thermal auto-restart, and diagnostic sink capability in a single SO-8 package - making it optimal for space-constrained, fault-aware DC load switching where channel independence and field reliability are prioritized.

FAQ
Is VNS3NV04D-E still in active production?
No - STMicroelectronics has marked VNS3NV04D-E as obsolete (as confirmed in the September 2013 Rev 3 datasheet). However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle support including cross-reference guidance and last-time-buy planning for ongoing production programs.
Can VNS3NV04D-E drive inductive loads directly without external flyback diodes?
Yes - its integrated 40 V drain-source clamp and 100 mJ single-pulse avalanche energy rating allow safe operation with inductive loads like solenoids and relays without external clamping components, provided peak stored energy stays within the rated limit and layout minimizes parasitic inductance.
How does the diagnostic feedback work during thermal shutdown?
When junction temperature exceeds 150–200 °C, the device sinks 10–20 mA through the INPUT pin. If driven by a low-impedance source (e.g., MCU GPIO with pull-up), this causes measurable voltage drop; if driven high-impedance, the INPUT pin collapses to ~0 V - both states are detectable by firmware without added circuitry.
What is the maximum recommended PCB copper area for thermal performance?
For optimal thermal resistance, ST specifies mounting on a standard single-sided FR4 board with ≥50 mm² of ≥35 µm thick copper connected to all DRAIN pins per channel - achieving Rthj-amb = 80 °C/W. Larger copper pours or internal layers further reduce thermal resistance in high-power layouts.
