Product details

Overview

VN02H-E 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 drain-source breakdown voltage, 0.4 Ω on-state resistance at 3 A, 6 A continuous output current, 5 V logic-compatible input, and integrated thermal/under-voltage shutdown protection.

For engineers reviewing the VN02H-E datasheet, VN02H-E pinout, VN02H-E application, or VN02H-E equivalent, key selection criteria include its open-drain diagnostic output for open-load and over-temperature detection, low standby power dissipation, ISO 7637-2 pulse 5 level III load-dump robustness, and PENTAWATT vertical package thermal performance (R_thj-case = 4.4 °C/W).

Technical Context

The VN02H-E integrates a high-side Power MOSFET with embedded protection logic, current-sensing circuitry, and an open-drain status output. Its thermal shutdown activates at 140–160 °C junction temperature and resets at 125–145 °C, enabling automatic recovery after fault clearance.

It supports 9–36 V supply operation with under-voltage lockout at 2.5–5 V, clamps inductive flyback to –2 V (typ.), and delivers controlled (di/dt)_on of 0.15 A/µs and (di/dt)_off of 0.4 A/µs under 3 A load conditions - critical for EMI management in 12 V/24 V vehicle subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Withstands load dump transients up to ISO 7637-2 Pulse 5 Level III without external clamping.
R_DS(on)	0.4 Ω @ T_j = 25 °C, I_OUT = 3 A - Enables ≤2.4 W conduction loss at 6 A, supporting thermally constrained PCB layouts.
I_OUT (cont.)	6 A @ T_c = 25 °C - Rated for continuous solenoid, lamp, and heater control in engine bay or chassis modules.
V_CC Range	9–36 V - Compatible with 12 V and 24 V automotive battery systems including cold-crank (≥6 V) and alternator surge conditions.
t_d(on)	5–20 µs - Ensures fast response for PWM-driven actuators while limiting dI/dt-induced noise coupling.
V_STAT (low)	0.4 V @ I_STAT = 1.6 mA - Provides clean TTL/CMOS-compatible diagnostic signal for microcontroller GPIO monitoring.
T_j Operating	–40 to +150 °C - Qualified for under-hood placement per AEC-Q100 Class 0 requirements (though not officially AEC-certified).

Pinout & Package

PENTAWATT (vertical) package: 5-pin single-in-line (SIP), isolated metal tab for heatsinking, R_thj-case = 4.4 °C/W, footprint optimized for forced-air or chassis-mount thermal management.

Pin/Terminal	Circuit Role	Design Meaning
1 (GND)	Power ground reference	Common return for internal protection circuitry; must be connected to system ground via low-inductance path.
2 (IN)	Logic input	5 V CMOS/TTL compatible; internal hysteresis (0.5 V) prevents noise-induced switching near threshold.
3 (OUT)	High-side switch output	Drives load between this pin and battery positive; handles 60 V transient clamping during inductive turn-off.
4 (V_CC)	Supply input	Accepts 9–36 V; internal UVLO disables output below 2.5 V to prevent erratic behavior during brownout.
5 (STAT)	Open-drain diagnostic output	Sinks current when open-load or over-temperature detected; requires external pull-up to V_CC or logic rail.

Key Features

Feature	Design Value
Integrated thermal shutdown	Auto-recovery at 125–145 °C reset temperature enables fault-tolerant operation without MCU intervention.
Open-drain status output	Single-pin reporting of both open-load (no current flow) and over-temperature faults simplifies diagnostics and reduces BOM count.
Load-dump immunity	Withstands ISO 7637-2 Pulse 5 Level III (12 V system: +110 V/100 ms) without external TVS, reducing board space and cost.
Low standby power	50 µA supply current in off-state minimizes parasitic drain on vehicle battery during sleep mode.
Inductive clamp voltage	–4 V typical flyback clamping limits voltage stress on downstream components and reduces EMI radiation.

Applications

Use Scenario: Controlling headlamps, fog lamps, and HVAC blowers in modern BCMs with centralized power distribution.

IC Role / Device Role / Timing Role: High-side driver replacing electromechanical relays; provides precise PWM dimming and real-time fault feedback to MCU.

Use Value: Eliminates contact wear, enables diagnostic logging of open-circuit faults, and reduces PCB area vs. discrete MOSFET + protection IC solutions.

Use Scenario: Driving 24 V solenoid valves and indicator lamps in factory automation I/O modules.

IC Role / Device Role / Timing Role: Robust output stage with built-in short-circuit protection and thermal foldback for unattended operation.

Use Value: Reduces need for external current sensing and thermal monitoring circuits, lowering design complexity and time-to-market.

Truck & Bus Lighting System

Off-Highway Equipment Control

Use Scenario: Managing stop/tail lights, turn signals, and marker lamps in heavy-duty vehicles with wide battery voltage range.

IC Role / Device Role / Timing Role: High-side switch with load-dump immunity and reverse-battery protection support via Schottky diode configuration.

Use Value: Survives harsh electrical environments (ISO 16750-2) without additional transient suppressors, improving field reliability.

Use Scenario: Controlling hydraulic pump motors and implement solenoids in construction and agricultural machinery.

Use Value: Prevents catastrophic failure during extended duty cycles in high-ambient-temperature cabins or engine compartments.

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
STSPIN250	Lower current rating (2.8 A), integrated current regulation, SPI interface, no open-drain STAT output.	Targeted at stepper motor gate drivers, not general-purpose high-side switching.	Choose only if closed-loop current control and digital configurability outweigh need for diagnostic reporting and 6 A capability.
IPS1021H	Higher voltage rating (600 V), lower current (1.2 A), integrated current sense analog output, same PENTAWATT package.	Designed for industrial AC/DC power supplies and mains-connected loads, not 12/24 V DC automotive systems.	Select when isolation, higher V_DSS, and analog current monitoring are required - not for direct replacement in VN02H-E designs.

Compared with STSPIN250 and IPS1021H, the VN02H-E uniquely balances 6 A drive strength, automotive-grade transient immunity, and dual-fault diagnostic reporting in a thermally efficient PENTAWATT package - making it optimal for cost-sensitive, high-reliability 12/24 V DC load switching where simplicity and field serviceability matter.

FAQ

What is the maximum safe operating voltage for VN02H-E in automotive load-dump conditions?

The VN02H-E is rated for 60 V V_DSS and withstands ISO 7637-2 Pulse 5 Level III (12 V system: +110 V for 100 ms) due to internal clamping. However, sustained voltage above 36 V increases power dissipation and triggers thermal shutdown; external clamping is recommended beyond that limit.

Can VN02H-E drive inductive loads without external flyback diodes?

Yes - the device integrates an active clamp that limits inductive flyback voltage to –4 V (typ.), eliminating the need for external freewheeling diodes in most 12/24 V solenoid and relay coil applications, though layout inductance must be minimized to avoid overshoot.

How does the open-drain STAT pin indicate open-load versus over-temperature faults?

Both conditions pull STAT low; differentiation requires timing analysis: open-load is reported within 100 µs of turn-on if no current flows, while over-temperature latches low until junction cools to ~125 °C. The truth table on page 5 of the datasheet defines exact state transitions.

Is VN02H-E qualified to AEC-Q100 standards?

No - the VN02H-E is not AEC-Q100 qualified. It meets key automotive electrical stress requirements (e.g., ISO 7637-2, reverse battery per Fig. 3), but lacks formal qualification documentation; for AEC-compliant designs, consider ST's AEC-Q100-qualified VIPower devices like VNQ5E050K.
