Product details

Overview

VNS1NV04D-E from STMicroelectronics is a dual-channel fully autoprotected power MOSFET in SO-8 package, integrating linear current limiting (1.7 A per channel), thermal shutdown (150–200 °C), and 40 V drain-source clamp. It replaces standard power MOSFETs in DC–50 kHz switching applications such as automotive body control modules and industrial I/O drivers.

For engineers reviewing the VNS1NV04D-E datasheet, VNS1NV04D-E pinout, VNS1NV04D-E application, or VNS1NV04D-E equivalent, this device offers diagnostic feedback via input pin voltage drop, direct gate access for analog driving, and rugged ESD protection (4 kV HBM, 16.5 kV output pins), critical for high-reliability load-switching designs.

Technical Context

The VNS1NV04D-E integrates two independent OMNIFET II chips in a single SO-8 package, each featuring VIPower M0-3 technology with monolithic thermal sensing, linear current limiting, and overvoltage clamping. Its input pin serves dual roles: gate drive interface and fault status indicator via sink current (10–20 mA) during overtemperature events.

Each channel operates with R_DS(on) = 250 mΩ at V_IN = 5 V and I_D = 0.5 A, and supports TTL-level input compatibility. Protection features are autonomous-no external components required-and triggered independently per channel based on junction temperature, drain current, and V_DS overvoltage.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	250 mΩ max per channel at 5 V input, enabling low conduction loss in 12 V automotive loads
I_lim	1.7 A typical per channel, linearly limiting current without latch-up during overload
V_clamp	40 V min drain-source clamp, protecting against inductive kickback in solenoid/relay drivers
T_jsh	150–200 °C overtemperature shutdown range, with automatic restart after ~15 °C hysteresis
I_gf	10–20 mA fault sink current on input pin, enabling simple open-collector fault detection
IISS	100–150 µA supply current from input pin, minimizing control-side power burden
ESD Rating	4000 V HBM on input, 16500 V on output pins-robust for factory handling and field deployment

Pinout & Package

Package: SO-8 (standard surface-mount, 1.27 mm pitch, 5.0 × 6.2 mm body). Pin assignments confirmed per STMicroelectronics DocID7395 Rev 4, Figure 1 (top view).

Pin/Terminal	Circuit Role	Design Meaning
1 (INPUT 1)	Channel 1 gate control & fault feedback	Accepts TTL-compatible logic; sinks 10–20 mA during overtemperature to signal fault
2 (SOURCE 2)	Channel 2 source reference	Common source node for Channel 2; tied internally to substrate for thermal coupling
3 (DRAIN 1)	Channel 1 power output	High-current switched output (up to 1.7 A); connected to all DRAIN1 pins for thermal spreading
4 (SOURCE 1)	Channel 1 source reference	Common source node for Channel 1; electrically isolated from SOURCE 2
5 (DRAIN 2)	Channel 2 power output	Independent high-current output (up to 1.7 A); thermally coupled to DRAIN 1 via shared leadframe
6 (INPUT 2)	Channel 2 gate control & fault feedback	Functionally identical to Pin 1; enables dual independent load control
7 (SOURCE 2)	Channel 2 source (redundant connection)	Second tie point to Channel 2 source for improved PCB routing and thermal dissipation
8 (DRAIN 1)	Channel 1 power output (redundant connection)	Second tie point to Channel 1 drain; reduces trace resistance and improves thermal conduction

Key Features

Feature	Design Value
Integrated linear current limiter	Stabilizes output current at 1.7 A per channel without external sense resistor or op-amp
Autonomous thermal shutdown	Self-contained junction temperature sensing triggers cutoff at 150–200 °C, no external sensor needed
Input-pin diagnostic feedback	Single-wire fault signaling: input pin voltage drops to near 0 V when overtemperature occurs
Direct gate access for analog driving	Enables precise linear-mode operation (e.g., current regulation) by bypassing internal driver logic
Output-stage ESD robustness	16.5 kV CDM-equivalent protection on drain/source pins ensures reliability in harsh assembly environments

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
VNS3NV04PTR-E	Higher R_DS(on) (350 mΩ), lower I_lim (1.2 A), same SO-8 package and protection set	Better suited for lower-power 5 V logic-driven loads where thermal margin is constrained	Select when board space is fixed and peak current demand ≤1.2 A per channel
IPS1021HTR	Single-channel, higher voltage rating (60 V), integrated SPI interface for diagnostics	Requires microcontroller communication; not pin-compatible; adds firmware overhead but enables real-time telemetry	Select when system-level diagnostics (e.g., current readback, fault history) outweigh cost and complexity trade-offs

Compared with VNS3NV04PTR-E and IPS1021HTR, the VNS1NV04D-E delivers optimal balance of current capability (1.7 A), thermal resilience, and analog simplicity-ideal for cost-sensitive, high-volume industrial and automotive modules requiring deterministic, self-contained protection without software dependency.

FAQ

Can VNS1NV04D-E be used in parallel for higher current?

No. The VNS1NV04D-E lacks current-sharing features such as matched R_DS(on) tracking or synchronized thermal shutdown. Parallel operation risks current imbalance and premature failure due to parametric spread and independent protection triggering. Use a single higher-current device like VNQ5E050AKTR-E instead.

What is the minimum input series impedance required for safe operation?

The datasheet specifies R_{IN MIN} = 330 Ω per channel. This limits inrush current during fast switching and ensures stable gate drive under fault conditions. Using lower impedance may cause excessive input current during overtemperature events and compromise diagnostic feedback integrity.

Does the device support PWM frequencies above 50 kHz?

No. The datasheet explicitly states suitability "from DC up to 50 kHz." At higher frequencies, thermal accumulation exceeds safe limits due to finite switching energy (E_as = 55 mJ) and R_DS(on) temperature coefficient. Operation beyond 50 kHz requires derating or alternative devices like the VIPower M0-5 family.

How is fault condition detected on the input pin?

During overtemperature shutdown, the device sinks 10–20 mA through the input pin. If driven by a low-impedance source (≤330 Ω), this pulls the input voltage toward 0 V. That voltage drop is monitored externally to trigger system-level fault response-no additional components or ADC channels required.
