Product details

Overview

VN02AN-12-E from STMicroelectronics is a high-side smart power solid-state relay built with VIPower technology, designed to drive grounded resistive or inductive loads in automotive and industrial control systems. It delivers 7 A continuous output current at Tc = 25 °C, features 60 V drain-source breakdown voltage, 0.35 Ω on-state resistance, integrated thermal shutdown (140 °C), and open-drain diagnostic output for overtemperature indication.

For engineers reviewing the VN02AN-12-E datasheet, VN02AN-12-E pinout, VN02AN-12-E application, or VN02AN-12-E equivalent, key selection criteria include its -18 V fast demagnetization clamp for inductive loads, 5 V logic-compatible input with hysteresis, under-voltage lockout (3.5–7 V), and PENTAWATT vertical package thermal performance (R_thj-case = 4 °C/W).

Technical Context

The VN02AN-12-E integrates a high-side Power MOSFET with protection logic, thermal sensing, and diagnostic feedback in a monolithic VIPower structure. Its internal circuitry enables automatic thermal reset (125 °C turn-on after 140 °C shutdown), under-voltage protection, and overcurrent detection via internal current-sense threshold (~15 A short-circuit peak).

It supports fast switching (t_d(off) = 14 µs, t_f = 4.5 µs) and provides active inductive load demagnetization with a controlled negative clamp (-14 to -24 V), reducing energy dissipation during turn-off by enabling rapid current decay without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Maximum drain-source blocking voltage; ensures safe operation with 36 V supply and transient spikes in 24 V automotive systems.
R_DS(on)	0.35 Ω (typ.) at I_OUT = 3 A - Low conduction loss enables 7 A continuous current with ≤1.7 W dissipation at 25 °C case temperature.
I_OUT	7 A continuous - Rated for sustained load driving at T_c = 25 °C; derates to ~0.6 A at T_c = 85 °C under short-circuit conditions.
V_DEMAG	-18 V (typ.) - Internally clamped negative voltage during turn-off accelerates inductive current decay and reduces switching losses.
T_TSD	140 °C - Thermal shutdown junction temperature; protects against latch-up and permanent damage during overload or poor heatsinking.
V_USD	3.5–7 V - Under-voltage lockout range prevents erratic operation during brown-out or cold-cranking in vehicle electrical systems.
V_IL/V_IH	0.8 V / 2 V - 5 V logic-compatible input thresholds with 0.5 V hysteresis ensure noise immunity in electrically noisy environments.

Pinout & Package

PENTAWATT (vertical) package: 5-pin single-in-line (SIP) thermally enhanced power package with isolated metal tab (pin 3 = Drain, pin 5 = Source); R_thj-case = 4 °C/W enables high-power operation with minimal heatsink.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (GND)	Logic ground reference	Reference for input logic and status output; must be tied to system signal ground, not chassis/power ground unless isolated per Fig. 4.
Pin 2 (IN)	Logic input	5 V CMOS-compatible control input with internal clamping (±6 V max); accepts TTL/CMOS levels with 0.5 V hysteresis.
Pin 3 (D)	Power drain	Main high-side switch output terminal; connects to load supply rail (V_CC = 9–36 V); electrically isolated metal tab for heatsinking.
Pin 4 (STAT)	Open-drain diagnostic output	Sinks up to 1.6 mA when overtemperature or undervoltage occurs; requires external pull-up to V_CC or logic rail.
Pin 5 (S)	Power source / load return	Connected to load low-side (grounded load); forms current path with pin 3; also serves as internal current-sense reference node.

Key Features

Feature	Design Value
Integrated thermal shutdown & auto-restart	Shuts off at 140 °C junction; resumes conduction at 125 °C - eliminates need for external thermal monitoring and manual reset.
Active inductive demagnetization	Internal -18 V clamp during turn-off - reduces flyback energy dissipation and eliminates external freewheeling diode requirement for many solenoid/valve drivers.
Undervoltage lockout (UVLO)	3.5–7 V activation window - prevents partial turn-on and shoot-through during low-battery conditions in automotive applications.
Diagnostic open-drain status output	Single-pin fault reporting for overtemperature and UVLO - simplifies microcontroller interface with one GPIO and pull-up resistor.
VIPower monolithic integration	Combines power MOSFET, driver, protection logic, and diagnostics on one die - improves reliability vs. discrete high-side driver + sense + protection solutions.

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
IPS1021H	Lower R_DS(on) (0.15 Ω), higher I_OUT (10 A), integrated current sense analog output	Requires external op-amp for current monitoring; no built-in -18 V demag clamp	Preferred for precision current-controlled loads; less suitable for unbuffered inductive switching without added clamp circuitry.
TPS27081A	Lower voltage rating (36 V), no thermal shutdown reset hysteresis, no diagnostic output	Designed for consumer-grade 5–24 V systems; lacks automotive-grade fault reporting and ruggedness	Cost-effective for non-safety-critical 24 V industrial controls where diagnostics are handled externally.

Compared with VN02AN-12-E, IPS1021H offers higher current capacity and analog sensing but sacrifices integrated demagnetization and simplified fault signaling; TPS27081A reduces cost and complexity but omits critical automotive protections and thermal recovery behavior.

FAQ

What is the maximum continuous output current for VN02AN-12-E, and under what thermal conditions?

The VN02AN-12-E delivers 7 A continuous output current at case temperature (T_c) = 25 °C. Current capability decreases with rising case temperature due to thermal derating: at T_c = 85 °C, average short-circuit current drops to 0.6 A. The device uses internal thermal shutdown (140 °C) and automatic restart (125 °C) to maintain safe operation without external intervention.

How does the VN02AN-12-E handle inductive load turn-off, and why is this important?

The VN02AN-12-E actively clamps the load voltage to -18 V (typ.) during turn-off, accelerating current decay in inductive loads like solenoids and relays. This reduces energy dissipation in the switch and eliminates arcing or voltage overshoot that could damage downstream components. Unlike passive freewheeling diodes, this internal function minimizes EMI and PCB footprint while improving system reliability.

Can VN02AN-12-E be used in reverse-battery protection configurations?

Yes - the VN02AN-12-E can withstand continuous -36 V reverse supply when protected with an external Schottky diode between pin 1 (GND) and chassis ground (Fig. 3). Alternatively, separating signal ground (pin 1) from power ground enables use of a standard diode. Input thresholds (V_IL, V_IH) and status voltage shift accordingly, so system-level grounding strategy must be validated per application circuit diagrams.

What does the STAT pin indicate, and how should it be interfaced?

The STAT pin is an open-drain output that sinks current during overtemperature or undervoltage fault conditions. It requires an external pull-up resistor (typically to V_CC or MCU I/O rail). When pulled low, it signals active fault; high-impedance state indicates normal operation. Leakage current is ≤10 µA, allowing direct connection to most microcontroller GPIO pins without level-shifting.
