Product details
Overview
VN02NSP 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-level compatible input control, integrated thermal and under-voltage shutdown, open-drain diagnostic output, and 0.4 Ω typical RDS(on) at 3 A and 25 °C - used in automotive body control modules for headlight and fan switching.
For engineers reviewing the VN02NSP datasheet, VN02NSP pinout, VN02NSP application, or VN02NSP equivalent, key selection criteria include its 60 V VDSS rating, 0.4 Ω on-resistance, thermal shutdown at 140 °C, diagnostic feedback capability, and PENTAWATT package suitability for high-power industrial and automotive load switching.
Technical Context
The VN02NSP integrates a VIPower high-side MOSFET switch with embedded protection circuitry including thermal shutdown (trip at 140 °C, reset at 125 °C), under-voltage 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 an open-drain configuration.
Control logic accepts 5 V TTL/CMOS-compatible inputs with 0.5 V hysteresis; input clamp voltage is ±0.7 V to 6 V. Switching performance includes 10 µs turn-on delay and 6 µs fall time at 3 A resistive load, with short-circuit response time of 1.5–5 ms depending on case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - maximum drain-source blocking voltage, enabling use in 24 V automotive systems with surge margin. |
| RDS(on) | 0.4 Ω (typ.) at IOUT = 3 A, Tj = 25 °C - determines conduction loss and thermal rise during sustained load operation. |
| IOUT (cont.) | 6 A @ Tc = 25 °C - defines maximum continuous load current before thermal derating applies. |
| VCC Range | 7–26 V - supply voltage range supporting 12 V/24 V battery systems with reverse-battery tolerance via external Schottky diode. |
| Thermal Shutdown | 140 °C trip / 125 °C reset - autonomous recovery behavior prevents latch-up and enables self-resetting fault handling. |
| Status Output | Open-drain diagnostic - sinks current when open load or over-temperature occurs, compatible with standard microcontroller GPIO inputs. |
| Input Logic | VIH = 2 V min, VIL = 0.8 V max - ensures robust interfacing with 5 V digital controllers without level-shifting. |
Pinout & Package
The VN02NSP is housed in a PENTAWATT (5-pin, single-in-line) thermally enhanced through-hole package with isolated heatsink tab (pin 3). The package supports >29 W power dissipation at Tc = 25 °C and features ECOPACK® lead-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power ground reference | Return path for load current and internal bias; requires low-impedance connection to system ground. |
| INPUT (Pin 2) | Digital control input | 5 V logic-compatible enable signal; internally clamped to −0.7 V / +6 V for ESD and overvoltage protection. |
| VCC (Pin 3) | Power supply input | Main supply rail (7–26 V); also serves as heatsink tab - must be electrically connected to PCB copper pour for thermal management. |
| STATUS (Pin 4) | Diagnostic output | Open-drain output indicating open load or over-temperature; requires external pull-up resistor to VCC or logic rail. |
| OUTPUT (Pin 5) | High-side switched output | Drives load between this pin and system ground; rated for 60 V blocking and 6 A continuous current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated thermal protection | Autonomous shutdown at 140 °C junction temperature with automatic restart at 125 °C - eliminates need for external thermal monitoring circuitry. |
| Open-load detection | Diagnosis of disconnected or broken-wire loads via STATUS pin - enables fail-safe diagnostics in safety-critical automotive applications. |
| Low standby power | 50 µA max supply current in off-state - reduces quiescent current draw in always-on vehicle subsystems. |
| Reverse-battery resilience | Supports −4 V reverse supply voltage; combined with external Schottky diode, withstands −26 V automotive reverse-battery transients. |
| Short-circuit response | 1.5–5 ms turn-off time under short-circuit conditions - limits energy dissipation and prevents catastrophic failure during fault events. |

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 |
|---|---|---|---|
| IPS1025H | Higher 25 A current rating, 3.3 V logic compatible, integrated current sense, smaller HTSSOP package | Better suited for higher-power motor drives and industrial PLC outputs requiring analog current feedback | Select when needing >6 A capability, current monitoring, or surface-mount assembly - not pin-compatible with VN02NSP. |
| TPS27081A | Lower 800 mA current rating, 1.8–6 V logic input, no thermal shutdown, SOIC-8 package | Targeted at low-power consumer electronics and USB-powered peripherals where diagnostics are secondary | Select for cost-sensitive, low-current applications without thermal or open-load diagnostics - not functionally equivalent. |
Compared with IPS1025H and TPS27081A, the VN02NSP uniquely balances 6 A drive capability, full diagnostic feedback (open-load + thermal), and rugged PENTAWATT packaging - making it optimal for mid-power automotive and industrial high-side switching where reliability and fault visibility are critical.

FAQ
What is the maximum continuous output current for VN02NSP?
The VN02NSP delivers 6 A continuous output current at case temperature (Tc) of 25 °C. Current capability decreases with rising Tc per the derating curve in Figure 10; at Tc = 85 °C, average short-circuit current drops to 0.9 A, and full 6 A operation requires adequate heatsinking or forced-air cooling.
How does the STATUS pin indicate fault conditions?
The STATUS pin is an open-drain output that pulls low (<0.4 V at 1.6 mA sink) during open-load (no connected load) or over-temperature (>140 °C) events. In normal operation, it remains high-impedance and requires an external pull-up resistor to VCC or logic rail to report high state.
Can VN02NSP be used in 24 V truck applications with reverse-battery protection?
Yes - the VN02NSP tolerates −4 V reverse supply voltage per absolute maximum ratings. For full −26 V reverse-battery protection per ISO 16750-2, ST recommends adding a Schottky diode between Pin 1 (GND) and system ground, as shown in Figure 12 of the datasheet.
Is VN02NSP pin-compatible with other ST high-side switches like VNQ5E050AK?
No - VN02NSP uses a 5-pin PENTAWATT package with unique pin assignment (GND, INPUT, VCC, STATUS, OUTPUT), while VNQ5E050AK is a 32-pin PowerSSO package with quad-channel architecture and different pinout, logic interface, and protection features. They are not mechanically or electrically interchangeable.
