STMicroelectronics VNV35NV04

Overview

VNV35NV04 from STMicroelectronics is a fully autoprotected monolithic Power MOSFET in the OMNIFET II family, designed for DC–25 kHz switching in harsh industrial environments. It features 10 mΩ R_DS(on) at 25°C, 30 A linear current limit, 40 V integrated overvoltage clamp, thermal shutdown at 150–200°C, and diagnostic feedback via the input pin. It replaces standard power MOSFETs in motor control, solenoid drivers, and load switching applications.

For engineers reviewing the VNV35NV04 datasheet, VNV35NV04 pinout, VNV35NV04 application, or VNV35NV04 equivalent, this device offers verified fault detection, rugged avalanche energy handling (1.7 J), low input supply current (100 µA typ), and compatibility with TTL logic - critical for reliable high-side switching in automotive body electronics and industrial PLC outputs.

Technical Context

The VNV35NV04 integrates gate control, linear current limiting, overtemperature sensing, and overvoltage clamping into a single VIPower M0-3 silicon die. Its input pin directly drives the internal power MOSFET gate while sourcing only 100 µA during normal operation and sinking up to 20 mA during fault conditions.

Protection functions operate independently of input drive: current limiting activates at 30–60 A depending on junction temperature; thermal shutdown triggers between 150–200°C with automatic restart after ~15°C cooldown; and the 40–55 V drain-source clamp enables safe inductive load switching without external snubbers.

Compared with VNV35NV04, BTS716G offers identical protection behavior and diagnostic signaling but at reduced current capacity and higher conduction loss, while STSPIN32F0A shifts focus to intelligent motor control rather than robust single-channel switching - making VNV35NV04 optimal for high-current, high-reliability on/off applications.

FAQ

What is the maximum continuous drain current for VNV35NV04?

The device features a linear current limiter set to 30 A minimum under typical conditions (V_IN=6 V, V_DS=13 V). This limit is temperature-dependent and rises to 60 A at low junction temperatures but remains internally enforced - no external current-sense resistor is needed to achieve this protection level.

Can VNV35NV04 be driven directly by a microcontroller GPIO?

Yes - the input pin accepts TTL/CMOS logic levels (V_INH ≥ 2.5 V, V_INL ≤ 0.5 V) and draws only 100–150 µA during normal operation. No level-shifting or gate-driver circuitry is required, though a series resistor ≥4.7 Ω is recommended to limit fault-sink current during diagnostics.

How does the diagnostic feedback function work during overtemperature fault?

When junction temperature exceeds T_jsh (150–200°C), the device actively sinks 10–20 mA through the INPUT pin. If the driving source has sufficient current capability, this pulls the input voltage low; if not, the pin collapses to 0 V - both states provide unambiguous fault indication without added components.

Is external clamping required when switching inductive loads?

No - the integrated 40–55 V drain-source clamp eliminates need for external TVS diodes or RC snubbers. Tested with 24 mH inductive loads and 24 V supply, it safely absorbs 1.7 J of single-pulse avalanche energy, making it suitable for solenoid, relay, and motor starter applications without auxiliary protection.
