Product details

Overview

VNB14N04TR-E from STMicroelectronics is a fully autoprotected N-channel Power MOSFET in the OMNIFET family, designed as a smart high-side switch replacement for standard MOSFETs in DC–50 kHz load control. It integrates linear current limiting (14 A), thermal shutdown (150 °C), and 42 V overvoltage clamp, with R_DS(on) = 0.07 Ω at V_IN = 10 V and I_D = 7 A. Used in industrial motor drives, solenoid controls, and lighting ballasts where fault resilience and diagnostic feedback are critical.

For engineers reviewing the VNB14N04TR-E datasheet, VNB14N04TR-E pinout, VNB14N04TR-E application, or VNB14N04TR-E equivalent, this page delivers verified electrical specs, validated PowerSO-10 pin mapping, real-world protection behavior, and direct alternatives for ruggedized high-side switching in harsh environments.

Technical Context

The VNB14N04TR-E implements ST's VIPower M0 technology to embed protection logic directly into the power stage. Its input pin serves dual roles: gate drive interface and fault status indicator-pulling low (~0 V) via 100 Ω during thermal shutdown. Current limiting operates independently of input voltage, maintaining I_lim = 14 A across V_IN = 5–10 V.

Protection activation is thermally localized: junction temperature sensing occurs near the power MOSFET die, enabling fast response (<60 µs step response at V_IN = 10 V). The integrated clamp handles unclamped inductive energy up to 0.65 J, while ESD rating meets 2000 V HBM.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Clamp	42 V - Internally clamped drain-source voltage prevents destructive overvoltage during inductive turn-off.
R_DS(on)	0.07 Ω @ V_IN = 10 V, I_D = 7 A - Enables low conduction loss in high-current switching paths.
I_lim	14 A - Linear current limit protects against short circuits without external sensing components.
T_jsh / T_jrs	150 °C shutdown / 135 °C reset - Hysteresis ensures stable recovery after thermal fault clearance.
Q_i	30 nC @ V_DD = 12 V - Input charge determines gate driver sizing for <200 ns switching transitions.
I_ISS	500 µA max @ V_IN = 10 V - Low quiescent current minimizes control-side power overhead.
E_AS	0.65 J - Single-pulse avalanche energy rating supports reliable operation under unclamped inductive stress.

Pinout & Package

Package: PowerSO-10 (TO-263-10), surface-mount, isolated heatsink tab (DRAIN), rated for 50 W total dissipation at T_C = 25 °C.

Pin/Terminal	Circuit Role	Design Meaning
1,2,4,5	SOURCE	Internal source connection; tied to PCB ground plane for low-inductance return path.
6,7,8,9,10	INPUT	Gate drive input and fault feedback node; sinks ~50 mA during thermal fault for open-collector status signaling.
TAB	DRAIN	High-current output terminal; electrically connected to heatsink for thermal management.

Key Features

Feature	Design Value
Integrated overvoltage clamp	42 V clamping threshold eliminates need for external TVS diodes in inductive load switching.
Diagnostic feedback via INPUT pin	Active-low fault signal (≈0 V via 100 Ω) enables real-time system-level fault detection without extra pins.
Linear current limitation	Maintains 14 A limit regardless of input voltage (5–10 V), simplifying driver design for variable supply rails.
Direct gate access	Analog-compatible input allows TTL/CMOS or PWM driving without level-shifting circuitry.
Rugged avalanche capability	0.65 J single-pulse energy rating supports reliable operation in unclamped inductive switching applications.

Applications

Use Scenario: Driving 12–24 V DC brushed motors in PLC-controlled conveyor systems with frequent start-stop cycles.

IC Role / Device Role / Timing Role: High-side smart switch providing current-limited, thermally protected motor on/off control with fault reporting.

Use Value: Eliminates discrete current-sense + comparator + latch circuitry while sustaining 14 A peak loads and surviving back-EMF transients.

Use Scenario: Controlling pneumatic solenoid valves in factory automation panels exposed to vibration and voltage spikes.

IC Role / Device Role / Timing Role: Fault-tolerant high-side driver with integrated clamp and thermal cutout for inductive coil switching.

Use Value: Withstands 42 V inductive kickback and reports faults via same pin used for enable, reducing wiring complexity and board space.

LED Lighting Ballast

Heating Element Control

Use Scenario: Switching constant-current LED strings in commercial signage with ambient temperatures up to 85 °C.

IC Role / Device Role / Timing Role: Thermally self-protected high-side switch managing up to 7 A continuous LED current.

Use Value: Built-in 150 °C thermal shutdown prevents LED driver failure due to heatsink degradation or airflow blockage.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side smart switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN7016F	Lower R_DS(on) (0.035 Ω), higher I_lim (16 A), but requires external 5 V supply for logic interface.	Designed for automotive 12 V systems with stricter EMC and qualification requirements.	Select when lower conduction loss and AEC-Q100 compliance are mandatory; not drop-in due to supply architecture.
IPS1025H	Higher V_DS clamp (60 V), faster fault response (<10 µs), but larger D2PAK package and higher cost.	Targeted at industrial safety-critical systems requiring SIL-2 functional safety support.	Choose for 60 V inductive loads or where sub-10 µs fault detection is required; pinout differs (8-pin SO).

Compared with STVN7016F and IPS1025H, the VNB14N04TR-E offers optimal balance of integration (single-supply operation), ruggedness (42 V clamp + 0.65 J avalanche), and cost for non-automotive industrial DC loads up to 24 V.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, specializing in power management, microcontrollers, and analog ICs for industrial, automotive, and consumer markets.

The OMNIFET product line delivers monolithic, autoprotected high-side switches using VIPower technology, targeting robust load control in harsh industrial environments without external protection circuitry.

FAQ

Can VNB14N04TR-E be used as a low-side switch?

No. The device is configured exclusively as a high-side switch: DRAIN is the output terminal (connected to load), SOURCE is internally tied to ground, and INPUT drives the gate. Using it as a low-side switch would reverse internal protection logic and disable fault feedback functionality.

What happens to R_DS(on) when operating at elevated temperature?

R_DS(on) increases with junction temperature-typical normalized value is 1.5× at 125 °C versus 25 °C. This rise is inherent to silicon MOSFET physics and is documented in Figure 12/13 of the datasheet; thermal derating must be applied in heatsink design.

Is external flyback diode required when driving inductive loads?

No. The integrated 42 V clamp and 0.65 J avalanche rating eliminate need for external flyback diodes in most DC–50 kHz inductive applications. However, for loads exceeding E_AS limits or requiring faster energy dissipation, an external diode remains recommended.

How is fault condition detected on the INPUT pin?

During thermal or short-circuit fault, internal circuitry disconnects the INPUT pin from the gate and pulls it to ground through a 100 Ω resistor. Monitoring this pin with a microcontroller GPIO reveals fault state as ≈0 V, distinguishable from normal high-impedance or driven states (≥0.8 V).
