Product details

Overview

VN02H from STMicroelectronics is a high-side smart power solid-state relay IC built with VIPower technology, designed to drive grounded resistive or inductive loads in automotive and industrial control systems. It features 60 V V_DSS, 0.4 Ω R_DS(on) at 3 A, 6 A continuous output current, 5 V logic-compatible input, and open-drain diagnostic output for open-load and over-temperature detection.

For engineers reviewing the VN02H datasheet, VN02H pinout, VN02H application, or VN02H equivalent, key selection criteria include thermal shutdown behavior (140–160 °C), under-voltage lockout (2.5–5 V), short-circuit response time (1.5–5 ms), and ISO 7637-2 pulse 5 load-dump robustness.

Technical Context

The VN02H integrates a high-side N-channel Power MOSFET with protection circuitry including thermal shutdown, under-voltage lockout, and over-current detection. Its diagnostic output signals open-circuit (no load) and over-temperature conditions via an open-drain structure referenced to ground.

It operates with supply voltage from 9 V to 36 V (clamped at 36 V above that), supports 5 V logic-level input with 0.5 V hysteresis, and delivers controlled switching with turn-on/turn-off delays of 5–20 µs and rise/fall times of 5–45 µs under 3 A resistive load.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Maximum drain-source breakdown voltage; defines safe operating voltage margin for automotive 24 V systems and load-dump transients.
R_DS(on)	0.4 Ω @ T_j = 25 °C, I_OUT = 3 A - Low conduction loss enables 6 A continuous operation at T_c = 25 °C with ≤28 W dissipation.
I_OUT (cont.)	6 A - Continuous output current rating at case temperature 25 °C; derates with junction temperature per R_thj-case = 4.4 °C/W.
V_CC Range	9–36 V - Valid supply range; clamps output at 36 V above this, triggering thermal shutdown if power dissipation exceeds limits.
t_SC	1.5–5 ms - Short-circuit switch-off time at V_CC = 13 V, R_LOAD < 10 mΩ; ensures fast fault isolation before destructive energy buildup.
T_TSD	140–160 °C - Thermal shutdown activation threshold; resets automatically at T_R = 125–145 °C for self-recovery after fault clearance.
V_USD	2.5–5 V - Under-voltage shutdown threshold; prevents erratic operation during brown-out or battery sag below functional minimum.

Pinout & Package

Packaged in PENTAWATT vertical (order code VN02H), a 5-pin through-hole power package with isolated heatsink tab (pin 3). Thermal resistance junction-to-case is 4.4 °C/W, enabling direct mounting to heatsinks for high-power switching.

Pin/Terminal	Circuit Role	Design Meaning
1 (GND)	Logic ground reference	Reference for input logic and status output; must be tied to system signal ground-separate from power ground in reverse-battery protection schemes.
2 (IN)	Control input	5 V logic-compatible TTL/CMOS input with 0.5 V hysteresis; accepts up to 6 V via external current-limiting resistor.
3 (DRAIN)	High-side power output	Switched high-side output terminal connected to load; requires external flyback diode for inductive loads.
4 (SOURCE)	Power return path	Connected to load's grounded side; forms current path with DRAIN; not internally connected to GND (pin 1).
5 (STAT)	Open-drain diagnostic output	Signals open-load (high impedance) or over-temperature (low) with internal pull-down; requires external pull-up resistor.

Key Features

Feature	Design Value
Integrated thermal shutdown	Auto-disable at 140–160 °C junction temperature with hysteresis-based auto-restart at 125–145 °C.
Open-load and over-temp diagnostics	Single open-drain STAT pin distinguishes no-load (high-Z) from over-temp (low) using timing-based detection >100 µs post-switch edge.
Load-dump immunity	Withstands ISO 7637-2 Pulse 5 (Level III) without external clamping, supporting 24 V automotive systems.
Reverse battery protection support	Compatible with Schottky diode between pin 1 and chassis ground; design allows separate signal/power ground partitioning to avoid VIH/VIL shift.
Low standby power	Off-state supply current ≤50 µA ensures minimal quiescent draw in always-on vehicle modules.

Applications

Automotive Body Control Module

Industrial PLC Output Stage

Use Scenario: Driving solenoids, fans, and lamps in vehicle door modules and lighting control units.

IC Role / Device Role / Timing Role: High-side switch replacing electromechanical relays; provides diagnostic feedback for OBD-II compliance.

Use Value: Eliminates contact wear and bounce; enables real-time open-circuit detection for predictive maintenance and fault logging.

Use Scenario: Controlling 24 V DC actuators and valves in factory automation I/O racks.

IC Role / Device Role / Timing Role: Solid-state output driver with integrated short-circuit and thermal protection for unattended operation.

Use Value: Reduces system downtime by auto-shutdown on overload and self-recovery after cooling-no manual reset required.

Truck & Bus Lighting System

Off-Highway Equipment Power Distribution

Use Scenario: Managing headlamp, fog lamp, and marker light circuits subject to ISO 7637-2 transients.

IC Role / Device Role / Timing Role: Load-dump hardened high-side switch with clamped V_CC and fast short-circuit response.

Use Value: Maintains functional safety during 12/24 V battery system surges up to ±100 V (Pulse 5 Level III), avoiding external TVS stacking.

Use Scenario: Powering hydraulic solenoids and sensor exciters in construction and agricultural machinery.

IC Role / Device Role / Timing Role: Ruggedized high-current switch with wide V_CC range (9–36 V) and -40 to 150 °C junction operation.

Use Value: Enables single-part sourcing across 12 V and 24 V platforms while meeting extended temperature and vibration requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STVN02HSP	Same die, enhanced package variant with improved thermal performance (R_thj-case = 3.8 °C/W vs. 4.4 °C/W); identical electrical specs.	Preferred for higher ambient or sustained 6 A loads where heatsinking is constrained.	Select when thermal margin is critical and board space allows PENTAWATT horizontal footprint.
IPS1021H	Lower R_DS(on) (0.25 Ω), higher I_OUT (10 A), integrated current sense; lacks open-load detection and uses SPI interface instead of analog STAT.	Suited for closed-loop current-controlled systems requiring telemetry-not drop-in replacement for diagnostic simplicity.	Choose only if digital monitoring and tighter current regulation outweigh need for analog STAT compatibility.

Compared with STVN02HSP and IPS1021H, the VN02H offers optimal balance of diagnostic simplicity, proven automotive qualification, and thermal robustness in legacy 5-pin PENTAWATT layouts-making it ideal for cost-sensitive, high-reliability relay replacements where open-load reporting is mandatory.

FAQ

What is the maximum continuous output current for VN02H and under what thermal conditions?

The VN02H delivers 6 A continuous output current at case temperature (T_c) = 25 °C. Current derating follows R_thj-case = 4.4 °C/W; at T_c = 85 °C, max continuous current drops to approximately 3.5 A. Junction temperature must remain ≤150 °C for reliable operation.

How does the open-drain STAT pin indicate open-circuit versus over-temperature conditions?

The STAT pin outputs high-impedance (open-circuit) when no load is connected, and low (≤0.4 V) during over-temperature events. Detection occurs >100 µs after switching edges, using internal logic to distinguish fault types-no external timing components required.

Can VN02H operate safely with a 42 V load-dump transient?

Yes-VN02H withstands ISO 7637-2 Pulse 5 Level III (±100 V, 100 ms), which covers typical 42 V transients. Its internal clamp limits V_CC to 36 V; excess energy dissipates thermally, and thermal shutdown activates if junction temperature exceeds 140 °C.

Is an external flyback diode required when driving inductive loads?

Yes-an external flyback diode must be placed across the inductive load (anode to GND, cathode to DRAIN) to clamp V_demag ≤ –2 V. The device does not integrate a freewheeling path; omitting the diode risks exceeding V_BRDSS and damaging the output stage.
