Product details

Overview

VNB14NV04-E from STMicroelectronics is a monolithic VIPower™ M0 OMNIFET II fully autoprotected N-channel Power MOSFET in TO-252 (DPAK) package, rated for 40 V clamp voltage, 35 mΩ R_DS(on) at 7 A/25 °C, and 12 A linear current limit. It replaces standard power MOSFETs in DC–50 kHz industrial load switching applications including automotive body electronics and industrial PLC outputs.

For engineers reviewing the VNB14NV04-E datasheet, VNB14NV04-E pinout, VNB14NV04-E application, or VNB14NV04-E equivalent, key selection criteria include integrated thermal shutdown (150–200 °C trip), diagnostic feedback via input pin sink current (10–20 mA), and rugged unclamped inductive switching capability (93 mJ E_AS).

Technical Context

The device integrates gate driver, protection logic, and power MOSFET on a single die using ST's VIPower M0 process. Its linear current limiter operates independently of input voltage, clamping drain current to 12–24 A depending on junction temperature while maintaining safe SOA during overload.

Overvoltage protection uses an internal clamp set at 45 V (typ.) with robust avalanche energy rating (400 mJ), and fault detection feeds back through the input pin by sinking up to 20 mA when T_j ≥ 170 °C, enabling host controller fault recognition without external sensors.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	35 mΩ max at V_IN = 5 V, I_D = 7 A, T_j = 25 °C - enables low conduction loss in high-current DC loads
I_lim	12 A min at V_IN = 5 V, V_DS = 13 V - provides predictable current limiting during short-circuit events
V_CLAMP	40–55 V at I_D = 7 A - protects against inductive kickback up to 45 V typical, eliminating need for external TVS
E_AS	400 mJ at T_j = 25 °C, V_DD = 24 V - supports reliable unclamped inductive switching in relay/coil drivers
T_jsh	150–200 °C - thermal shutdown activates before silicon damage, with automatic restart after ~15 °C cooldown
I_gf	10–20 mA sink current at fault - allows direct interface with microcontroller GPIO for real-time fault reporting
P_tot	74 W at T_c = 25 °C (DPAK) - defines maximum continuous power dissipation with proper heatsinking

Pinout & Package

TO-252 (DPAK) package: surface-mount, 3-pin, exposed drain pad for thermal conduction. Pin 1 (Input), Pin 2 (Source), Pin 3 (Drain). Drain pad electrically connected to Pin 3 and serves as primary thermal path.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (IN)	Logic-level input / gate control / fault feedback node	Accepts 0–5 V TTL-compatible drive; sinks 10–20 mA during overtemperature fault for diagnostics
Pin 2 (SOURCE)	Power return / reference node for current sensing	Internally tied to substrate; used as common return for load current and diagnostic monitoring
Pin 3 (DRAIN)	Main power output / high-side switch node	Connected to exposed copper pad; carries full load current and dissipates heat directly to PCB

Key Features

Feature	Design Value
Integrated linear current limiter	Clamps I_D to 12–24 A independent of V_IN, preventing runaway during short circuits
Thermal shutdown with auto-restart	Trips at 150–200 °C; resets at ~135 °C, enabling self-recovery without system reset
Diagnostic feedback via input pin	Sinks 10–20 mA fault current - eliminates need for external sense resistor or comparator
On-chip overvoltage clamp	45 V typical clamp threshold with 400 mJ avalanche energy - replaces discrete TVS in inductive load designs
ESD robustness	4 kV HBM (input), 16.5 kV CDM (output) - ensures reliability in handling and assembly environments

Equivalent & Alternatives

The following parts are listed as comparable options for similar protected high-side switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Integrated stepper motor driver (dual H-bridge), 45 V max, no linear current limit per channel	Designed for bipolar stepper control, not discrete high-side load switching	Select only if driving stepper motors; lacks VNB14NV04-E's diagnostic feedback and single-channel robustness
IPS1021H	Higher R_DS(on) (100 mΩ), lower I_lim (4.5 A), same DPAK package and fault sink capability	Better suited for low-power, space-constrained applications where 12 A limit is excessive	Choose for cost-sensitive, lower-current designs requiring identical footprint and diagnostic interface

Compared with STSPIN250 and IPS1021H, VNB14NV04-E uniquely balances 12 A current limit, 35 mΩ conduction loss, and diagnostic sink current in a single DPAK package-making it optimal for mid-power industrial and automotive high-side switching where both performance and fault visibility are required.

FAQ

What is the maximum operating frequency for VNB14NV04-E?

The device is specified for DC to 50 kHz operation under normal conditions. Switching times (td(on)/tr/td(off)/tf) range from 80 ns to 1 µs depending on gate drive impedance, enabling efficient PWM control in motor drives and lighting ballasts without exceeding thermal limits.

Can VNB14NV04-E be used in high-side configuration only?

Yes - VNB14NV04-E is designed exclusively as a high-side switch with source referenced to ground. Its input pin controls the internal gate, and the drain connects to the load supply rail; it cannot function as a low-side switch due to internal topology and diagnostic architecture.

How does the diagnostic feedback work during overtemperature fault?

When junction temperature exceeds the shutdown threshold (150–200 °C), the device sinks 10–20 mA from the input pin. If driven by a low-impedance source (e.g., MCU GPIO), this pulls the input voltage low; if driven high-impedance, the pin collapses to ~0 V - both states signal fault to the controller without external circuitry.

Is external flyback diode required when switching inductive loads?

No - the integrated 45 V clamp and 400 mJ avalanche energy rating eliminate the need for an external flyback diode in most 12–24 V inductive applications. However, for loads exceeding 93 mJ unclamped energy or requiring faster demagnetization, an external diode remains recommended per layout and timing constraints.
