Product details

Overview

VNV49N04 from STMicroelectronics is a fully autoprotected monolithic Power MOSFET in VIPower™ M0 technology, designed as a robust replacement for standard N-channel MOSFETs in DC–50 kHz switching applications. It delivers 49 A current limit (ILIM), 42 V integrated overvoltage clamp (VCLAMP), and 20 mΩ R_DS(on) at V_IN = 10 V, with built-in thermal shutdown and diagnostic feedback via the input pin-used in industrial motor control, solenoid drivers, and automotive body electronics.

For engineers reviewing the VNV49N04 datasheet, VNV49N04 pinout, VNV49N04 application, or VNV49N04 equivalent, key selection criteria include its linear current limiting behavior, fault-sensing capability through the INPUT pin, junction temperature-dependent protection thresholds (T_jsh = 150 °C), and compatibility with TTL-level drive without external gate resistors.

Technical Context

The VNV49N04 integrates a power MOSFET stage with analog gate control, enabling direct TTL-compatible driving while maintaining precise linear current limitation independent of input voltage. Its internal clamp circuit activates at 42 V to suppress inductive kickback, and the device enters thermal shutdown when junction temperature exceeds 150 °C, resetting automatically at 135 °C.

Protection logic is implemented directly in the power die region for fast response: short-circuit detection triggers within 35–150 µs (depending on V_IN), and fault status is signaled by pulling the INPUT pin to ground via a 100 Ω internal resistor-enabling real-time system-level diagnostics without additional sensing components.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CLAMP	42 V typical; clamps inductive transients to protect downstream circuitry without external TVS diodes
R_DS(on)	20 mΩ max at V_IN = 10 V, I_D = 25 A; enables low conduction loss in high-current loads
I_LIM	49 A typical at V_IN = 10 V; provides repeatable current limiting across temperature and supply variations
T_jsh / T_jrs	150 °C shutdown / 135 °C reset; tight hysteresis ensures stable thermal recovery after overload
I_gf	50 mA fault sink current at V_IN = 10 V; drives standard optocoupler or microcontroller input reliably
Q_i	100 nC total input charge; supports fast switching with moderate gate driver strength (R_gen = 10 Ω)
E_AS	4 J single-pulse avalanche energy; sustains unclamped inductive turn-off events without failure

Pinout & Package

Package: PowerSO-10 (surface-mount, 10-lead, exposed drain pad). Thermal resistance R_thj-case = 1 °C/W enables high-power operation with minimal heatsinking.

Pin/Terminal	Circuit Role	Design Meaning
INPUT	Gate control and fault feedback node	Accepts TTL/CMOS logic input; sinks 50 mA during fault to signal overtemperature or short circuit
DRAIN	Main power output terminal	Internally connected to all drain-source paths; electrically tied to exposed pad for thermal and electrical conduction
SOURCE	Power return and reference node	Provides low-impedance return path; used as local ground reference for internal protection circuitry
CLAMP	Overvoltage clamp connection	Internal connection to clamp circuit; not user-accessible-functions autonomously during inductive flyback
GND	Logic ground reference	Separate from SOURCE to isolate digital control domain from high-current power return

Key Features

Feature	Design Value
Linear current limitation	Stabilizes load current at 49 A regardless of input voltage or temperature-prevents runaway during short circuits
Integrated overvoltage clamp	42 V clamping threshold eliminates need for external snubbers in relay/solenoid drivers
Diagnostic feedback via INPUT pin	Active-low fault signaling (100 Ω pull-down) enables immediate microcontroller detection without ADC or comparator
Direct TTL-compatible drive	Operates with 5 V logic without level-shifting; draws only 550 µA IISS at V_IN = 10 V
Rugged avalanche capability	4 J single-pulse E_AS rating allows safe operation under unclamped inductive switching stress

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN840	Integrated 3-phase gate driver + current sense; no built-in clamp or thermal shutdown	Targeted at BLDC motor control-not suitable for standalone solenoid/motor switching	Select only if multi-phase commutation and analog current feedback are required
IPS1021H	Higher R_DS(on) (45 mΩ), lower I_LIM (12 A), same V_CLAMP (42 V), smaller PowerSSO-36 package	Better suited for space-constrained 12 V automotive loads below 10 A	Prefer for compact PCB layouts where 49 A capacity is unnecessary

Compared with VNV49N04, STSPIN840 lacks autonomous protection and requires external gate resistors and sense amplifiers, while IPS1021H trades current capacity and thermal margin for footprint reduction-making VNV49N04 optimal for high-reliability 24–48 V industrial loads demanding full self-protection.

FAQ

What is the maximum continuous drain current for VNV49N04?

The VNV49N04 does not specify a fixed continuous I_D rating due to its active current-limiting architecture. Instead, it guarantees a linear current limit of 49 A (typical) at V_IN = 10 V, with thermal shutdown activating above 150 °C junction temperature. Actual steady-state current depends on PCB copper area, heatsinking, and ambient conditions-derating curves show 25 A sustainable at T_c = 70 °C with PowerSO-10 mounting.

Can VNV49N04 be used as a high-side switch with 5 V logic control?

Yes-VNV49N04 accepts 5 V TTL/CMOS logic directly on its INPUT pin, drawing only 550 µA supply current. It achieves R_DS(on) ≤ 20 mΩ at 5 V drive (typical), and its fault feedback remains functional: during overtemperature, the INPUT pin is actively pulled to ground with 100 Ω impedance, detectable by any microcontroller GPIO with weak pull-up.

How does the integrated clamp protect against inductive kickback?

The internal clamp activates when drain-source voltage exceeds 42 V (typical), diverting flyback energy into the chip's rugged avalanche structure. This limits V_DS to ≤50 V (max) during turn-off of inductive loads like solenoids or relays-eliminating need for external TVS diodes or RC snubbers. The 4 J E_AS rating ensures survival across repeated unclamped switching events.

Is VNV49N04 pin-compatible with VNB49N04?

No-VNV49N04 uses PowerSO-10 packaging (10-lead surface-mount), while VNB49N04 uses TO-263 (D2PAK) packaging (3-lead through-hole/surface-mount). Though electrically identical in function and specifications, their mechanical footprints, thermal paths, and soldering requirements differ significantly; PCB layout and assembly processes must be redesigned for interchange.
