Product details

Overview

VN5R003HTR-E from STMicroelectronics is a reverse battery protection switch built on VIPower® technology, functioning as a high-side load switch with automatic negative-voltage shutdown. It features 3 mΩ on-state resistance, -16 V to 28 V operating supply range, and integrated ESD protection (5 kV HBM), deployed in automotive electronic control units to prevent damage from incorrect battery polarity connection.

For engineers reviewing the VN5R003HTR-E datasheet, VN5R003HTR-E pinout, VN5R003HTR-E application, or VN5R003HTR-E equivalent, this device is selected for robust reverse-polarity protection in 12 V/24 V battery-supplied systems where low R_ON, thermal resilience, and ISO 7637-2 transient immunity are critical design requirements.

Technical Context

The VN5R003HTR-E implements a power MOSFET-based high-side switch with intrinsic body-diode behavior when IN is open, enabling passive reverse-battery blocking without external components. Its control logic is voltage-referenced between IN and Drain: a negative Drain-to-IN voltage forces automatic turn-off, while negative Drain-to-Source voltage (reverse battery) triggers conduction only when IN is biased positively relative to Drain.

It integrates electromagnetic compatibility features including optimized emissions and low susceptibility, complies with RoHS (2002/95/EC), and meets ISO 7637-2 pulse test levels III and IV for automotive transients-including ±100 V pulse 1, +50 V pulse 2a, and +87 V pulse 5b-under defined PCB thermal conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
On-state resistance (R_ON)	3 mΩ at 10 A, 25°C - enables <0.3 W conduction loss at 10 A, minimizing thermal stress in compact ECUs.
Operating supply range (V_S)	-16 V to 28 V - supports full automotive battery range including cold-crank (-16 V) and load-dump (up to +28 V).
Reverse input current (I_IN(REV))	-2 to 0 mA at V_S = -16 V - ensures negligible leakage during reverse-battery fault, preventing false wake-up.
Junction temperature range (T_j)	-40°C to 150°C - qualified for under-hood automotive environments with sustained high-temperature operation.
ESD rating (HBM)	5000 V - protects against handling-induced electrostatic discharge without external TVS diodes.
Thermal resistance (R_thj-case)	0.5 °C/W - allows efficient heat transfer to heatsink or copper plane, supporting >60 A pulsed current capability.
Drain-source clamp voltage (V_CLPDS)	17–23 V at I_S = -5 A - limits energy dissipation during inductive turn-off, protecting downstream circuitry.

Pinout & Package

Delivered in the HPAK package (6-pin, exposed drain tab), the VN5R003HTR-E uses a thermally enhanced surface-mount configuration with four Source pins, one Drain pin (connected to the exposed metal tab), one IN control pin, and one NC pin. The tab must be soldered to a large copper area for thermal management and electrical grounding of the Drain node.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 6, 7 (SOURCE)	Power MOS source terminal	Common low-side return path; electrically tied internally; requires low-impedance PCB routing to minimize voltage drop.
3 (IN)	Control input	Voltage-referenced gate driver input; turn-on occurs when V_IN > V_DRAIN; open-circuit defaults to OFF state.
4 (DRAIN)	Power MOS drain terminal	Connected to exposed metal tab; carries full load current and must be thermally coupled to PCB copper pour.
5 (NC)	No connect	Internally unconnected; must remain floating-no PCB trace or solder mask opening required.

Key Features

Feature	Design Value
Automatic reverse-battery shutdown	Turns OFF when Drain voltage falls below IN by >0.5 V - eliminates need for external sensing or control logic.
Integrated ESD protection	5 kV HBM on all pins - removes requirement for discrete ESD suppressors in cost-sensitive ECU designs.
Low quiescent current in OFF state	<2 µA typical - enables always-connected battery architectures without parasitic drain.
ISO 7637-2 transient immunity	Passes Level IV pulses (±100 V, +87 V) with no functional degradation - validated per automotive EMC standards.
VIPower® process technology	Monolithic integration of logic, protection, and power MOSFET - delivers robust short-circuit and thermal foldback without external components.

Equivalent & Alternatives

The following parts are listed as comparable options for similar reverse battery protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPS4H160-Q1	Higher R_ON (12 mΩ), integrated diagnostics (current sense, fault reporting), SPI interface	Requires microcontroller interface and layout for analog monitoring; suited for ASIL-B diagnostic coverage	Select when functional safety compliance (ISO 26262) and real-time current telemetry are required.
MC33883	Discrete gate driver + external MOSFET solution; R_ON determined by external FET choice	Offers scalable current rating but increases BOM count, layout area, and thermal design complexity	Select when >100 A peak current or custom thermal partitioning is needed beyond HPAK's 60 A limit.

Compared with TPS4H160-Q1 and MC33883, the VN5R003HTR-E provides lowest conduction loss and simplest implementation for cost- and space-constrained reverse-battery protection, trading off programmability and scalability for minimal component count and proven automotive qualification.

FAQ

What is the maximum continuous current rating for VN5R003HTR-E?

The VN5R003HTR-E supports 60 A continuous current at T_j = 25°C with adequate PCB copper area (≥6 cm²). Derating applies above 25°C ambient: at 100°C case temperature, max continuous current drops to ~35 A per thermal data in Table 4 and Figure 4 of the datasheet.

Does VN5R003HTR-E require an external pull-down resistor on the IN pin?

No. The IN pin has internal biasing that ensures the device remains in the OFF state when left open. External pull-down is unnecessary and not recommended, as it may interfere with the voltage-referenced turn-on condition (V_IN > V_DRAIN) required for activation.

Can VN5R003HTR-E be used in 24 V commercial vehicle applications?

Yes. Its operating supply range extends to 28 V, and it passes ISO 7637-2 Pulse 5b up to +87 V with external load-dump clamp, making it suitable for 24 V truck and bus systems where higher battery float voltages and transient energy are present.

How is thermal performance affected if the exposed Drain tab is not soldered to PCB copper?

Without soldering the Drain tab to ≥6 cm² of 70 µm-thick copper, R_thj-amb degrades from 42 °C/W to >80 °C/W, causing rapid thermal runaway above 15 A. ST specifies mandatory tab soldering per Figure 7 and Table 4; omitting it violates the qualified thermal model and voids reliability guarantees.
