Product details

Overview

VNB14NV04TR-E from STMicroelectronics is a monolithic VIPower™ M0 OMNIFET II fully autoprotected high-side N-channel Power MOSFET in TO-252 (DPAK) package, featuring 35 mΩ R_DS(on), 12 A linear current limit, and integrated overvoltage clamp at 40 V. It replaces standard power MOSFETs in DC–50 kHz industrial load switching applications including automotive body control modules and industrial PLC outputs.

For engineers reviewing the VNB14NV04TR-E datasheet, VNB14NV04TR-E pinout, VNB14NV04TR-E application, or VNB14NV04TR-E equivalent, key selection criteria include thermal shutdown threshold (150–200 °C), diagnostic feedback via input pin sink current (10–20 mA), and unclamped inductive energy handling (93 mJ).

Technical Context

This device integrates gate driver, protection logic, and power stage on a single die using ST's VIPower M0 process. Its linear current limiter operates independently of input voltage, maintaining constant 12 A limit across temperature while enabling analog driving via direct gate access.

Thermal shutdown triggers at junction temperatures between 150 °C and 200 °C with automatic restart at ~135 °C; fault status is signaled by sinking 10–20 mA through the input pin during overtemperature events, requiring no external pull-up for detection.

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 12 V automotive and industrial loads
Current Limit (I_lim)	12 A min at V_IN = 5 V, V_DS = 13 V - provides predictable short-circuit current limiting without external sensing
Clamp Voltage (V_CLAMP)	40 V typ at I_D = 7 A - protects against inductive kickback up to 45 V, eliminating need for external TVS in many 24 V systems
Thermal Shutdown (T_jsh)	150–200 °C range - fast-acting junction-sensing shutdown prevents thermal runaway under sustained overload
Fault Sink Current (I_gf)	10–20 mA at T_j = T_jsh - delivers unambiguous open-drain fault signal compatible with TTL/CMOS logic inputs
Input Supply Current (I_ISS)	100–150 µA at V_IN = 5 V - ultra-low quiescent drive requirement simplifies microcontroller GPIO interfacing
Avalanche Energy (E_as)	400 mJ single-pulse at V_DD = 24 V - supports robust operation in unclamped inductive switching (e.g., solenoids, relays)

Pinout & Package

TO-252 (DPAK) package: surface-mount, 3-pin, exposed drain pad for thermal dissipation. Pin 1 = Input (IN), Pin 2 = Source (S), Pin 3 = Drain (D). The exposed drain tab is electrically connected to Pin 3 and must be soldered to PCB copper for thermal performance.

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 thermal fault to signal error condition
Pin 2 (S)	Source terminal / reference node	Common return path for load current; tied to system ground in high-side configuration
Pin 3 (D)	Drain terminal / power output	Connects to positive supply rail; carries full load current; thermally coupled to exposed pad

Key Features

Feature	Design Value
Linear current limitation	Maintains precise 12 A current ceiling regardless of input voltage or temperature-enables predictable fault behavior without external current sense resistors
Integrated overvoltage clamp	40 V clamping threshold with rugged avalanche capability-eliminates need for discrete TVS diodes in 24 V industrial control outputs
Diagnostic feedback via IN pin	Sinks 10–20 mA during thermal shutdown-provides direct, logic-compatible fault reporting without auxiliary circuitry
Direct gate access (analog driving)	Allows variable gate voltage control for soft-start or current ramp shaping-supports analog dimming or controlled inrush management
ESD protection	4 kV HBM (input), 16.5 kV CDM (output)-ensures robustness during board assembly and field handling in harsh environments

Use Value: Prevents fuse blowing during locked-rotor conditions by holding current at 12 A while allowing safe thermal recovery.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Integrated half-bridge driver with PWM control; lower R_DS(on) (20 mΩ); no linear current limit	Designed for bidirectional motor control-not suitable for simple on/off high-side switching	Select when bidirectional drive or PWM modulation is required; not a drop-in replacement for basic protected switching
VND5E025AKTR-E	Higher R_DS(on) (25 mΩ typ), lower I_lim (7 A), same DPAK package and diagnostic feedback	Optimized for lower-power 5 V logic-driven loads; reduced energy handling (E_as = 120 mJ)	Prefer for cost-sensitive, lower-current applications where 7 A limit suffices and 400 mJ avalanche margin is unnecessary

Compared with VNB14NV04TR-E, STSPIN250 adds motor control functionality but removes autonomous current limiting, while VND5E025AKTR-E trades current capacity and ruggedness for lower conduction loss and cost in lighter-duty applications.

FAQ

What is the maximum continuous drain current for VNB14NV04TR-E?

The device features a linear current limit of 12 A minimum under typical operating conditions (V_IN = 5 V, V_DS = 13 V). This is not a pulsed rating-it is actively enforced across temperature and remains stable up to 150 °C junction temperature before thermal shutdown intervenes.

Can VNB14NV04TR-E be used in low-side switching configurations?

No-it is optimized exclusively for high-side switching. The internal architecture ties the source to ground reference and uses the input pin to control the gate relative to source; reversing connections violates absolute maximum ratings and disables protection features.

How does the diagnostic feedback signal work during thermal fault?

When junction temperature exceeds the shutdown threshold (150–200 °C), the device sinks 10–20 mA through the IN 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 indicate fault without requiring external components.

Is an external flyback diode required when driving inductive loads?

Yes-an external freewheeling diode is mandatory across the load. While the integrated clamp limits V_DS to ~40 V, it is not rated for continuous energy dissipation; the external diode handles steady-state demagnetization current, preserving device reliability and thermal margin.
