STMicroelectronics VNS1NV04DTR-E

Overview

VNS1NV04DTR-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), 40 V overvoltage clamp, and diagnostic feedback via input pin. It replaces standard power MOSFETs in DC–50 kHz switching applications such as automotive body control modules and industrial solenoid drivers.

For engineers reviewing the VNS1NV04DTR-E datasheet, VNS1NV04DTR-E pinout, VNS1NV04DTR-E application, or VNS1NV04DTR-E equivalent, key selection criteria include per-channel R_DS(on) (250 mΩ), fault-sink current (10–20 mA), input threshold voltage (0.5–2.5 V), and SO-8 thermal resistance (80 °C/W).

Technical Context

The VNS1NV04DTR-E integrates two independent OMNIFET II chips using ST's VIPower M0-3 technology, each featuring direct gate access for analog driving and internal protection circuitry including linear current limiting, overtemperature sensing, and clamped avalanche energy handling (55 mJ). Its dual-channel architecture enables independent control of two inductive loads without external protection components.

Protection logic operates autonomously: overvoltage clamp activates at 36 V threshold with 40–55 V clamping range; current limit engages within 2.0 µs; thermal shutdown triggers between 150–200 °C with automatic restart after ~15 °C hysteresis. Fault status is signaled by sinking up to 20 mA through the input pin during overtemperature events.

FAQ

Can VNS1NV04DTR-E be used in high-side switching configurations?

No - the device is designed exclusively for low-side switching. Its source terminals are referenced to system ground, and there is no floating supply or level-shifting circuitry to support high-side operation. Attempting high-side use will prevent proper gate biasing and disable protection functions.

What is the maximum recommended PCB copper area for thermal performance?

For the specified R_thj-amb = 80 °C/W rating, ST specifies a minimum 50 mm² of ≥35 µm thick copper connected to all drain pins per channel. Increasing copper area beyond this yields diminishing returns; doubling area typically improves thermal resistance by only 10–15 %.

Does the input-pin fault feedback require external pull-up or pull-down resistors?

No external bias is required. During normal operation, the input pin draws only 100–150 µA. During thermal fault, it actively sinks 10–20 mA - sufficient to pull a standard 10 kΩ pull-up to ≤0.2 V, directly indicating fault to a microcontroller GPIO.

Is VNS1NV04DTR-E qualified for automotive AEC-Q100?

No - the datasheet explicitly states "NOT FOR AUTOMOTIVE OR SAFETY-CRITICAL APPLICATIONS" and prohibits use in life-support, implanted, or automotive environments. It is intended for industrial and consumer equipment where functional safety certification is not mandated.
