Product details

Overview

VN02N(011Y) from STMicroelectronics is a high-side smart power solid-state relay IC designed for driving resistive or inductive loads with one side grounded. It delivers 6 A continuous output current at Tc=25°C, features 5 V logic-compatible input control, thermal and under-voltage shutdown protection, open-drain diagnostic output, and 0.4 Ω typical RDS(on) at 3 A and 25°C - used in automotive body control modules for lamp and solenoid switching.

For engineers reviewing the VN02N(011Y) datasheet, VN02N(011Y) pinout, VN02N(011Y) application, or VN02N(011Y) equivalent, key selection criteria include its high-side configuration, integrated diagnostics, thermal reset behavior (140°C trip / 125°C recovery), and PENTAWATT package thermal resistance (4.35 °C/W junction-to-case).

Technical Context

The VN02N integrates a VIPower high-side MOSFET switch with on-die protection circuitry including thermal sensing, undervoltage lockout (6.5 V threshold), and open-load detection. Its diagnostic output provides active-low status signaling for over-temperature and open-circuit conditions via truth table-defined logic states.

Switching performance is characterized at VCC = 13 V: turn-on delay is 10 µs, rise time 15 µs, turn-off delay 15 µs, and fall time 6 µs into a 3 A resistive load. The device operates across -40°C to 125°C junction temperature with 29 W maximum power dissipation at Tc ≤ 25°C.

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.) @ I_OUT=3 A, T_j=25°C - Enables low conduction loss and <1.8 W dissipation at 3 A.
I_OUT (cont.)	6 A @ T_c=25°C - Continuous load current capability with derating above case temperature.
V_CC	7–26 V - Wide supply range compatible with 12 V/24 V battery systems and brown-out resilience.
Thermal shutdown	140°C trip / 125°C reset - Hysteresis prevents oscillation during thermal recovery; protects against short-circuit faults.
Status output	Open-drain, logic-level compatible - Signals open load or over-temp by pulling low; requires external pull-up for interface.
Input compatibility	5 V TTL/CMOS - VIH ≥ 2 V, VIL ≤ 0.8 V; internal 6 V clamp enables safe interfacing with higher-voltage controllers via series resistor.

Pinout & Package

The VN02N(011Y) is housed in a PENTAWATT package - a 5-pin, single-in-line (SIP), through-hole, thermally enhanced plastic package with exposed metal tab for heatsinking. Pin 1 is GND, Pin 2 is INPUT, Pin 3 is STATUS, Pin 4 is VCC, and Pin 5 is OUTPUT (drain). The metal tab is electrically connected to the OUTPUT terminal and must be isolated from chassis ground unless referenced as common return.

Pin/Terminal	Circuit Role	Design Meaning
1 (GND)	Power ground reference	Return path for input logic and internal bias; not connected to load ground - separates signal and power domains.
2 (INPUT)	Logic enable input	5 V-compatible digital control; internal hysteresis (0.5 V) rejects noise; clamped at 6 V for overvoltage tolerance.
3 (STATUS)	Open-drain diagnostic output	Active-low indicator: low = open load or over-temp; high-impedance otherwise; requires external pull-up resistor.
4 (VCC)	Power supply input	7–26 V main supply; powers internal circuitry and gate driver; includes under-voltage shutdown at 6.5 V.
5 (OUTPUT)	High-side switched output	Drain of integrated VIPower MOSFET; connects to load high-side; metal tab is electrically tied to this pin.

Key Features

Feature	Design Value
Integrated thermal protection	Automatic shutdown at 140°C junction temperature with 15°C hysteresis ensures reliable fault recovery without external sensors.
Open-load detection	Diagnoses disconnected loads via STATUS pin - critical for safety-critical automotive lighting and valve control.
Low standby power	50 µA max supply current in off-state - minimizes parasitic drain in always-on vehicle subsystems.
Reverse-battery ready	With external Schottky diode on GND pin, withstands -26 V reverse supply - meets ISO 7637-2 pulse requirements.
Automotive-grade ruggedness	Qualified per AEC-Q100 stress tests; ESD rated to 2000 V (HBM); operates from -40°C to +125°C junction.

Use Value: Junction-to-case thermal resistance of 4.35 °C/W allows direct mounting to chassis heatsink - avoids costly forced-air cooling.

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), higher I_OUT (10 A), integrated current sense, SPI interface	Requires microcontroller interface; supports closed-loop current monitoring and programmable trip thresholds	Choose when digital diagnostics, adjustable protection, or higher current drive is required - adds firmware complexity.
TPS27081A	Lower voltage rating (36 V), no integrated open-load detection, smaller SOIC-8 package, no metal tab	Lacks thermal reset hysteresis and STATUS pin logic; suited for space-constrained non-automotive industrial use	Choose for cost-sensitive, lower-power (≤2 A) applications where diagnostics are handled externally and thermal margin is sufficient.

Compared with IPS1021H and TPS27081A, the VN02N(011Y) offers optimal balance of analog simplicity, automotive qualification, and integrated diagnostics - ideal for legacy ECU designs needing drop-in reliability without software overhead.

FAQ

What is the function of the STATUS pin on VN02N(011Y)?

The STATUS pin is an open-drain output that signals fault conditions: it pulls low during open-load (no connected load) or over-temperature events (T_j ≥ 140°C). In normal operation, it remains high-impedance and requires an external pull-up resistor to VCC or controller I/O. Its logic state is defined in Table 8 (Truth Table) of the datasheet and does not indicate short-circuit events directly.

Can VN02N(011Y) be used in 24 V commercial vehicle systems?

Yes - the VN02N(011Y) supports VCC from 7 V to 26 V and is qualified for automotive applications per AEC-Q100. Its 60 V V_DSS rating provides margin against ISO 7637-2 load-dump transients (up to ±100 V), and its thermal shutdown (140°C) and derating curve (Figure 10) ensure safe operation in engine bay environments up to 85°C ambient.

How does the VN02N(011Y) handle reverse battery connection?

The VN02N(011Y) is not inherently reverse-battery protected. Per Figure 12 in the datasheet, a Schottky diode must be placed between Pin 1 (GND) and system ground to block -26 V reverse supply. This introduces a forward voltage shift (~0.3–0.5 V) affecting VIL/VIH thresholds and under-voltage detection level, which must be accounted for in controller design.

Is the metal tab on the PENTAWATT package electrically isolated?

No - the exposed metal tab is internally connected to Pin 5 (OUTPUT/drain) and is not insulated. It must be electrically isolated from chassis ground using mica or polymer insulating washers if mounted to a conductive heatsink. Failure to isolate risks shorting the load output to ground and damaging the device.
