STMicroelectronics VND7NV04

Overview

VND7NV04 from STMicroelectronics is a fully autoprotected high-side Power MOSFET switch in the OMNIFET II family, designed for DC–50 kHz inductive load control in automotive and industrial power distribution systems. It features 60 mΩ R_DS(on) at 3.5 A and 25 °C, 6 A linear current limit, 40 V integrated overvoltage clamp, thermal shutdown at 150–200 °C, and diagnostic feedback via input pin. Used in body control modules for solenoid, relay, and lamp driving.

For engineers reviewing the VND7NV04 datasheet, VND7NV04 pinout, VND7NV04 application, or VND7NV04 equivalent, key selection criteria include its linear current limiting behavior under overload, fault-sinking diagnostic capability (15 mA), low input supply current (100–150 µA), and rugged unclamped inductive switching performance up to 40 mJ.

Technical Context

The VND7NV04 integrates gate driver, protection logic, and VIPower M0-3 high-voltage DMOS in a monolithic structure. Its linear current limiter operates independently of input voltage, clamping drain current to 6–12 A depending on junction temperature, while the overvoltage clamp activates at 36 V threshold and sustains 40–55 V during transients.

Thermal shutdown triggers between 150–200 °C with automatic restart at ~135 °C; fault detection is implemented by sinking 15 mA through the input pin when T_j exceeds shutdown threshold, enabling direct interface with microcontroller GPIO without external circuitry.

Key Specifications

Pinout & Package

VND7NV04 is supplied in TO-252 (DPAK) package: surface-mount, 3-pin, exposed drain pad for thermal dissipation. Thermal resistance R_thj-case = 2.1 °C/W max enables >4.6 W continuous power dissipation at T_c = 25 °C.

FAQ

What is the maximum continuous drain current for VND7NV04 at 85 °C case temperature?

At T_c = 85 °C, the maximum continuous drain current is derated to approximately 3.8 A based on the device's R_thj-case = 2.1 °C/W and thermal shutdown threshold of 150–200 °C. This assumes adequate PCB copper area (≥100 mm²) and free-air convection. Full 6 A current limit remains active during transient overloads regardless of temperature.

Can VND7NV04 drive inductive loads without an external flyback diode?

Yes - the integrated 40–55 V overvoltage clamp and 200 mJ avalanche energy rating allow safe unclamped inductive switching for loads up to 0.7 mH at 13.5 V. However, for repetitive high-energy switching or loads exceeding 40 mJ, an external freewheeling diode is recommended to reduce junction temperature rise and extend lifetime.

How does the diagnostic feedback via the input pin function during thermal fault?

When junction temperature exceeds T_jsh (150–200 °C), the device sinks 15 mA through the input pin. If driven by a low-impedance source (e.g., MCU GPIO with 20 mA drive), this pulls the input voltage low, signaling fault. With high-impedance drivers, the pin falls to 0 V - still detectable as logic-low without affecting normal operation.

Is VND7NV04 compliant with RoHS and automotive qualification standards?

Yes - VND7NV04 is lead-free and RoHS-compliant (per 2002/95/EC). It is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C ambient) and designed for automotive power distribution applications, with validated performance across temperature, humidity, and vibration stress tests per ISO 16750.
