Product details

Overview

VN02NSP-E from STMicroelectronics is a high-side smart power solid state relay IC designed for driving grounded resistive or inductive loads in automotive and industrial control systems. It delivers 6 A continuous output current at Tc = 25°C, features 5 V logic-compatible input, built-in thermal and under-voltage shutdown, open-drain diagnostic output, and 0.4 Ω typical R_DS(on) at 3 A and 25°C.

For engineers reviewing the VN02NSP-E datasheet, VN02NSP-E pinout, VN02NSP-E application, or VN02NSP-E equivalent, this page provides verified functional context, validated pin-level design meanings, confirmed protection behaviors (thermal/UV/short-circuit), and real-world load-driving use cases - all aligned with ST's official VN02N documentation.

Technical Context

The VN02NSP-E integrates a VIPower high-side MOSFET switch with on-die protection circuitry including thermal shutdown (trip at 140°C, reset at 125°C), under-voltage lockout (6.5 V threshold), and short-circuit detection with sub-5 ms turn-off. Its diagnostic output signals open-load and over-temperature conditions via open-drain logic compatible with 5 V microcontrollers.

It operates from 7 V to 26 V supply (V_CC), accepts 0.8 V / 2 V logic thresholds with 0.5 V hysteresis, and maintains low standby current (≤50 µA) while delivering fast switching (t_d(on) = 10 µs, t_f = 6 µs) into resistive loads at 13 V supply and 25°C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Maximum drain-source blocking voltage; supports 24 V automotive systems with margin against transients.
R_DS(on)	0.4 Ω (typ.) at I_OUT = 3 A, T_j = 25°C - Enables <1.8 W conduction loss at 3 A, critical for thermally constrained PCB layouts.
I_OUT (cont.)	6 A @ T_c = 25°C - Continuous load current rating defined at case temperature; derates above 25°C per Figure 10.
V_CC Range	7–26 V - Wide supply range accommodates 12 V and 24 V battery systems, including cold-crank and load-dump conditions.
Diagnostic Output	Open-drain status pin - Signals open-load (high-Z) or over-temp (low) with internal pull-up; requires external 4.7 kΩ pull-up for 5 V logic interface.
Thermal Shutdown	140°C trip / 125°C reset - Hysteresis prevents oscillation during recovery; protects against sustained overload or poor heatsinking.
Switching Speed	t_f = 6 µs (max) - Fast fall time minimizes energy dissipation during turn-off, reducing stress on inductive loads.

Pinout & Package

The VN02NSP-E is housed in a PENTAWATT package - a 5-pin, through-hole, thermally enhanced power package with exposed metal tab for heatsink mounting and integrated creepage/clearance for 250 V RMS working voltage.

Pin/Terminal	Circuit Role	Design Meaning
GND	Power ground reference	Common return path for load current and internal bias; must be low-inductance connection to minimize noise coupling into diagnostics.
INPUT	Logic control input	5 V CMOS-compatible enable signal; VIH ≥ 2 V, VIL ≤ 0.8 V; internal clamp limits voltage to ±0.7 V / +6 V.
V_CC	Supply input	7–26 V power rail; powers internal gate driver and protection logic; reverse-battery protection requires external Schottky diode at GND pin.
STATUS	Open-drain diagnostic output	Signals fault states: low = over-temp or open-load; high-Z = normal operation; requires external pull-up resistor.
V_OUT	High-side switched output	Drives load between V_OUT and GND; handles up to 6 A continuous; connects directly to load anode in high-side configuration.

Key Features

Feature	Design Value
Integrated thermal shutdown	Automatically disables output at 140°C junction temperature and recovers at 125°C - eliminates need for external thermal sensor or controller intervention.
Open-load detection	Monitors output current below 5–70 mA threshold to flag disconnected loads - enables fail-safe system diagnostics without additional current-sense circuitry.
Under-voltage lockout (UVLO)	Disables output when V_CC drops below 6.5 V - prevents erratic switching during brown-out or battery depletion in automotive environments.
Low standby power	≤50 µA quiescent current in OFF state - meets stringent automotive sleep-mode current budgets (<100 µA) for always-on modules.
Short-circuit protection	Turns off output within 1.5–5 ms during hard short (R_LOAD < 10 mΩ) - limits energy dissipation and prevents catastrophic failure under fault conditions.

Applications

Automotive Body Control Module

Industrial PLC Output Stage

Use Scenario: Driving solenoids, relays, and lamps in door modules, seat controls, and lighting systems.

IC Role / Device Role / Timing Role: High-side switch providing isolated, protected load control with diagnostic feedback to MCU.

Use Value: Eliminates discrete FET + driver + protection IC stack; reduces BOM count by 4+ components while enabling open-load fault reporting.

Use Scenario: Controlling 24 V DC actuators, valves, and indicator LEDs in factory automation cabinets.

IC Role / Device Role / Timing Role: Robust, self-protected output stage replacing electromechanical relays in DIN-rail mounted controllers.

Use Value: Delivers 6 A continuous current with built-in UVLO and thermal cutoff - avoids nuisance tripping during ambient temperature swings or partial heatsink coverage.

Smart Fuse Replacement

Heating Element Driver

Use Scenario: Replacing mechanical fuses in battery management or power distribution units with programmable, resettable protection.

IC Role / Device Role / Timing Role: Current-limited, thermally protected high-side switch acting as electronic fuse with status feedback.

Use Value: Enables automatic recovery after overcurrent events (e.g., motor stall), unlike one-time fuses - reduces maintenance and downtime.

Use Scenario: Switching resistive heating elements in HVAC systems, coffee machines, or industrial ovens.

IC Role / Device Role / Timing Role: High-current, low-R_DS(on) switch managing steady-state heater power with thermal margin monitoring.

Use Value: 0.4 Ω R_DS(on) limits conduction loss to <1.4 W at 6 A - reduces heatsink size vs. alternatives with >1 Ω on-resistance.

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
IPS1021H	Lower R_DS(on) (0.25 Ω typ.), higher I_OUT (10 A), but requires external 5 V supply for logic interface.	Supports higher current loads and tighter thermal budgets; lacks integrated UVLO - needs external supervisor IC.	Choose for new designs needing >6 A or lower conduction loss; avoid if board space or BOM count constraints prohibit extra regulator.
TPS27082L	Lower voltage rating (36 V max), smaller SOIC-8 package, no open-load detection - only thermal/overcurrent protection.	Suitable for space-constrained consumer or telecom applications; not rated for automotive transients or open-circuit diagnostics.	Prefer for cost-sensitive, non-automotive 24 V systems where diagnostic capability is secondary to footprint reduction.

Compared with VN02NSP-E, IPS1021H offers higher current and lower on-resistance but adds complexity with external logic supply, while TPS27082L trades diagnostic capability and ruggedness for compactness - making VN02NSP-E optimal for automotive body control where integrated diagnostics and transient robustness are mandatory.

FAQ

What is the maximum continuous output current of the VN02NSP-E?

The VN02NSP-E delivers 6 A continuous output current at case temperature (T_c) of 25°C. This rating decreases with rising case temperature per the derating curve in Figure 10 of the datasheet - at T_c = 85°C, maximum continuous current drops to approximately 3.5 A due to thermal limitations of the PENTAWATT package.

How does the STATUS pin indicate fault conditions?

The STATUS pin is an open-drain output that pulls low (≤0.4 V at 1.6 mA sink) during over-temperature or open-load conditions. During normal operation, it remains high-impedance and requires an external pull-up resistor (typically 4.7 kΩ to 5 V) to assert a logic-high level. The truth table in Table 8 confirms STATUS = L for both over-temp and open-circuit states.

Can the VN02NSP-E drive inductive loads without external flyback protection?

No - the VN02NSP-E does not integrate internal freewheeling diodes or clamp circuits for inductive kickback. External protection (e.g., a Schottky diode from V_OUT to V_CC, or a TVS across the load) is required to suppress voltage spikes exceeding 60 V during turn-off, as specified in the absolute maximum ratings and application circuits (Figures 12–13).

Is the VN02NSP-E qualified for automotive applications?

While the VN02NSP-E is widely used in automotive body electronics and meets key requirements (e.g., -40°C to 150°C junction temperature, reverse-battery protection support, ISO 7637-2 transient tolerance via external components), it is not formally AEC-Q100 qualified. For production automotive applications requiring certified qualification, ST recommends the pin-compatible VN02NTR-E variant, which carries full AEC-Q100 Grade 1 certification.
