Product details

Overview

VNB14N04-E from STMicroelectronics is a fully autoprotected Power MOSFET in the OMNIFET family, designed as a smart high-side switch replacement for standard MOSFETs in DC–50 kHz power control applications. It features integrated linear current limiting (14 A), thermal shutdown (150 °C), 42 V overvoltage clamp, 0.07 Ω R_DS(on) at 10 V_IN, and diagnostic feedback via the input pin - enabling robust load driving in industrial motor controls and solenoid interfaces.

For engineers reviewing the VNB14N04-E datasheet, VNB14N04-E pinout, VNB14N04-E application, or VNB14N04-E equivalent, key selection criteria include its built-in fault detection capability, gate-accessible analog drive mode, rugged unclamped inductive switching performance (0.65 J E_AS), and compatibility with TTL-level logic inputs.

Technical Context

The VNB14N04-E integrates a VIPower M0 process-based vertical power MOSFET with monolithic protection circuitry including a voltage-clamped drain-source path, temperature-sensing junction monitoring, and linear current regulation independent of input voltage. Its input pin serves dual roles: gate control during normal operation and open-drain fault reporting (100 Ω pull-down) during thermal or short-circuit events.

It operates as a high-side switch with direct gate access for analog driving, supports up to 18 V input voltage, draws only 250–500 µA quiescent current from the input, and delivers 7 A continuous drain current with 50 W total dissipation in PowerSO-10 package at T_C = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Clamp	42 V - protects against inductive kickback in relay/solenoid loads without external TVS
R_DS(on)	0.07 Ω @ V_IN = 10 V, I_D = 7 A - enables low conduction loss in 12 V automotive/industrial systems
I_LIM	14 A - programmable current limit prevents wire/fuse damage during overload
T_JSH	150 °C - thermal shutdown triggers before silicon degradation, with 135 °C auto-restart hysteresis
E_AS	0.65 J - single-pulse avalanche energy rating ensures reliability under unclamped inductive switching
I_ISS	250–500 µA - ultra-low input supply current simplifies biasing in battery-powered controllers
Q_i	30 nC - moderate gate charge supports fast switching (t_r/t_f < 200 ns) with 10 Ω driver

Pinout & Package

Package: PowerSO-10 (TO-263-10), surface-mount, thermally enhanced with exposed drain tab.

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 control input and fault feedback node; sinks ~50 mA during thermal fault
TAB	Drain	High-current output terminal; electrically connected to exposed metal tab for heatsinking

Key Features

Feature	Design Value
Integrated overvoltage clamp	42 V clamping threshold eliminates need for external transient suppressors in 24 V systems
Linear current limitation	14 A hard limit active across full input voltage range (5–18 V), enabling predictable fault behavior
Diagnostic feedback	Input pin transitions to ~0 V via 100 Ω internal pull-down during fault - detectable with single resistor and MCU ADC
Direct gate access	Allows analog PWM or linear regulation by varying input voltage - not limited to digital on/off
ESD protection	2000 V HBM rating - withstands handling and board-level ESD without external protection diodes

Applications

Industrial Motor Control

Solenoid & Valve Actuation

Use Scenario: Driving 12–24 V DC brushed motors in PLC I/O modules with stall and wiring-fault protection.

IC Role / Device Role / Timing Role: High-side smart switch providing current-limited, thermally protected power delivery with real-time fault reporting.

Use Value: Eliminates discrete current sense + comparator + shutdown logic; reduces BOM count by ≥4 components while improving system MTBF.

Use Scenario: Controlling pneumatic/hydraulic solenoids in factory automation panels where inductive kick and coil shorts are common.

IC Role / Device Role / Timing Role: Protected high-side driver with integrated clamp and fast fault response (<60 µs current-limit step).

Use Value: Prevents MOSFET destruction during solenoid de-energization; enables immediate diagnostics without adding external snubbers or sense resistors.

Automotive Body Control

Heating Element Management

Use Scenario: Switching interior lighting, seat heaters, or mirror actuators in 12 V vehicle subsystems requiring load dump tolerance.

IC Role / Device Role / Timing Role: Automotive-grade high-side driver compliant with ISO 7637-2 pulse 5a (load dump) due to 42 V clamp and rugged avalanche rating.

Use Value: Withstands 35 V transients without derating; avoids need for external TVS diodes in cost-sensitive body electronics designs.

Use Scenario: Managing resistive heating elements (e.g., defrosters, HVAC duct heaters) with precise current limiting and thermal margin control.

IC Role / Device Role / Timing Role: Current-regulated power switch that maintains constant power delivery despite resistance drift with temperature.

Use Value: Enables stable heater output without external current loops; thermal shutdown prevents overheating of plastic housings or wiring insulation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN7016AJR	Lower R_DS(on) (0.025 Ω), higher I_OUT (20 A), SPI interface, no analog gate drive	Requires microcontroller communication; lacks direct analog input capability	Select when digital control and higher current are prioritized over simplicity and analog flexibility
Infineon BTS716G	Higher R_DS(on) (0.012 Ω typ), integrated current sense, no clamp, lower E_AS (0.15 J)	No integrated overvoltage clamp; requires external protection for inductive loads	Select when precise current measurement is needed and external clamping can be accommodated

Compared with STVN7016AJR and BTS716G, the VNB14N04-E uniquely balances analog drivability, self-contained protection (clamp + thermal + current), and minimal external component count - making it optimal for cost-sensitive, standalone high-side switching where firmware overhead or layout space is constrained.

FAQ

What is the maximum operating frequency for VNB14N04-E?

The VNB14N04-E is rated for DC to 50 kHz operation per ST's official specification. Its switching times (t_r/t_f < 200 ns with 10 Ω gate driver) support efficient PWM control in motor drives and SMPS auxiliary circuits, but sustained operation above 50 kHz may exceed thermal limits due to increased switching losses in the PowerSO-10 package.

Can VNB14N04-E be used as a low-side switch?

No - the VNB14N04-E is configured exclusively as a high-side switch. Its internal architecture connects the drain to the exposed tab (output), source pins to ground, and input pin to gate. Using it as a low-side switch would reverse internal protection logic and disable fault reporting, violating absolute maximum ratings and voiding safe operation guarantees.

How is fault condition detected on the input pin?

During thermal or short-circuit fault, the internal protection circuit disconnects the input from the gate and pulls the input pin to ground through a 100 Ω internal resistor. This causes the input voltage to drop to ≤0.3 V when monitored with a typical 10 kΩ pull-up - enabling simple MCU GPIO or comparator-based fault detection without additional components.

Does VNB14N04-E require an external flyback diode for inductive loads?

No - the integrated 42 V drain-source clamp provides inherent protection against inductive kickback, eliminating the need for an external flyback diode in most 12–24 V applications. However, for loads exceeding the device's 0.65 J single-pulse avalanche energy rating or operating at high repetition rates, an external diode remains recommended to reduce junction temperature stress.
