STMicroelectronics VND14NV04

Overview

VND14NV04 from STMicroelectronics is a monolithic VIPower™ M0 OMNIFET II fully autoprotected N-channel Power MOSFET in TO-251 (IPAK) package, rated for 40 V drain-source clamp voltage, 12 A current limit, and 35 mΩ R_DS(on) at V_IN = 5 V and T_j = 25 °C. It integrates linear current limitation, thermal shutdown, short-circuit protection, and diagnostic feedback via the input pin, enabling robust high-side switching in automotive body control modules and industrial PLC output stages.

For engineers reviewing the VND14NV04 datasheet, VND14NV04 pinout, VND14NV04 application, or VND14NV04 equivalent, key selection criteria include its integrated fault feedback capability, 150–175 °C thermal shutdown threshold, 100–150 µA input supply current, and compatibility with TTL-level drive - all critical for designing fail-safe load switches in harsh 12 V/24 V DC systems.

Technical Context

The VND14NV04 implements a self-protected power switch architecture using ST's VIPower™ M0 process, combining a vertical N-channel DMOS transistor with on-chip protection logic. Its input pin directly controls the gate through low-impedance path, while simultaneously sourcing diagnostic current (10–20 mA) during overtemperature fault to signal shutdown without external circuitry.

Protection functions operate independently of input voltage: linear current limiting activates at 12–24 A depending on junction temperature, thermal shutdown triggers between 150–200 °C, and the integrated avalanche-rated clamp sustains 40–55 V unclamped inductive energy. The device supports switching up to 50 kHz with turn-on delay under 250 ns (R_GEN = 10 Ω) and reverse recovery time of 300 ns.

FAQ

What is the maximum continuous drain current for VND14NV04?

The VND14NV04 does not specify a continuous drain current rating due to its integrated thermal protection. Instead, it features a linear current limiter set to 12 A minimum at V_IN = 5 V and V_DS = 13 V. Sustained operation above this limit causes automatic thermal shutdown at 150–200 °C junction temperature, preventing permanent damage.

Can VND14NV04 be used in high-side or low-side configurations?

The VND14NV04 is configured exclusively as a high-side switch. Its Source pin is internally referenced to system ground, and Drain connects to the load's positive supply. Low-side use is not supported - attempting to float the Source pin violates absolute maximum ratings and disables protection circuitry.

How does the diagnostic feedback function work during thermal fault?

When junction temperature exceeds the shutdown threshold (T_jsh), the VND14NV04 actively sinks 10–20 mA from the Input pin. If driven by a low-impedance source (e.g., MCU GPIO), this pulls the input voltage toward 0 V, signaling fault. If driven by high-impedance source, the pin voltage collapses naturally - no external pull-down required.

Is external clamping diode required when driving inductive loads?

No external clamping diode is required. The VND14NV04 integrates an overvoltage clamp with 40–55 V threshold and rugged avalanche capability (400 mJ single-pulse). This safely dissipates inductive energy during turn-off, eliminating need for external TVS or freewheeling diodes in typical 12 V/24 V solenoid and relay applications.
