Product details
Overview
VN330SP-E from STMicroelectronics is a quad-channel high-side smart power solid-state relay fabricated in VIPower technology, designed to drive resistive or inductive loads with one side grounded. It delivers 0.7 A per channel, features built-in current limiting (ILIM = 0.7–2.5 A), thermal shutdown (TTSD = 150–170 °C), and open-drain diagnostic output for fault reporting-used in industrial PLC I/O modules requiring robust load control and real-time fault detection.
For engineers reviewing the VN330SP-E datasheet, VN330SP-E pinout, VN330SP-E application, or VN330SP-E equivalent, this page provides verified electrical parameters, PowerSO-10 package layout, protection behavior under short-circuit/overtemperature, and direct alternatives for programmable logic controller and NC machine I/O design.
Technical Context
The VN330SP-E integrates four independent high-side switches with active current limiting, undervoltage lockout (VUSD = 5–8 V), and fast demagnetization (Vdemag = VCC−65 to VCC−45 V). Each channel uses a MOSFET-based power stage with internal clamping (VICL ≥ 32 V) and logic-level input compatibility (VIH = 3.5 V, VIL = 2 V).
Diagnostic functionality is implemented via an open-drain DIAG pin that pulls low during overtemperature or undervoltage events, with status determined >100 µs after switching edges. Truth table behavior confirms fault isolation per channel without cross-talk, supporting reliable multi-load monitoring in safety-critical industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 10–36 V - supports wide industrial supply rails including 24 V DC systems with margin for transients |
| RDS(on) | 0.2 Ω (TJ = 25 °C) - enables <150 mW conduction loss at 0.7 A, reducing thermal stress on PCB |
| ILIM (DC Short-Circuit) | 0.7–2.5 A - actively limits fault current to protect wiring and upstream supplies during sustained shorts |
| td(OFF) | 20–40 µs - ensures rapid turn-off for inductive loads, minimizing energy dissipation during switching |
| TTSD / TR | 150–170 °C / 135–155 °C - hysteresis prevents thermal oscillation during overload recovery |
| VDIAG Low | ≤1 V @ IDIAG = 5 mA - guarantees clean logic-low signal for microcontroller interrupt or status polling |
| Input Clamp Voltage | ≥32 V - allows direct connection to 24 V logic with immunity to 30 V field transients |
Pinout & Package
Delivered in PowerSO-10 package: thermally enhanced surface-mount outline with exposed die pad (Rth(JC) = 2 °C/W), optimized for industrial board layouts with forced-air or minimal heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Primary 10–36 V rail for all four channels; connects to system +24 V with local 100 nF decoupling |
| GND | Power ground reference | Common return for load current and internal bias; must be low-impedance path to avoid false shutdown |
| IN1–IN4 | Digital input control | CMOS-compatible inputs (VIH = 3.5 V); floating state defaults to OFF per channel |
| OUT1–OUT4 | High-side switched outputs | Four independent load connections; each drives one side of resistive/inductive load to GND |
| DIAG | Open-drain fault indicator | Active-low output signaling overtemperature, undervoltage, or short-circuit; requires external pull-up |
Key Features
| Feature | Design Value |
|---|---|
| Quad high-side switching | Four isolated 0.7 A channels enable compact replacement of discrete relays or optocoupled drivers in I/O modules |
| Fast demagnetization | Vdemag down to VCC−65 V accelerates energy decay in solenoids and contactors, preventing arcing and coil damage |
| Integrated diagnostics | Single DIAG pin reports per-channel faults without additional sensing circuitry-reduces BOM count and layout area |
| Input voltage clamping | 32 V minimum clamp protects against field-wiring transients, eliminating need for external TVS diodes on IN pins |
| Thermal shutdown with hysteresis | 150–170 °C trip and 135–155 °C reset avoids cycling during intermittent overloads in enclosed cabinets |
Applications
| PLC Digital Output Module | Industrial CNC Machine I/O |

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 |
|---|---|---|---|
| IPS2050H | Single-channel, higher current (2.5 A), no integrated DIAG pin; requires external fault monitoring | Better suited for high-power single-load applications (e.g., motor starters), not multi-channel I/O consolidation | Select when needing >2 A per channel and willing to add external sensing; not drop-in for quad-channel designs |
| TPS27082L | Quad-channel, lower current (0.5 A), no thermal shutdown or avalanche rating; TI's SmartFET with basic current limit only | Limited to non-safety-critical consumer-grade automation where thermal derating is acceptable | Choose for cost-sensitive, low-ambient-temp applications lacking surge or long-term overload exposure |
Compared with VN330SP-E, IPS2050H offers higher per-channel current but lacks integrated diagnostics and multi-channel integration, while TPS27082L provides quad integration at lower performance and no thermal protection-making VN330SP-E optimal for industrial PLCs demanding reliability, fault visibility, and thermal resilience.

FAQ
What is the maximum safe operating temperature for VN330SP-E?
The junction operating temperature is internally limited by thermal shutdown at 150–170 °C, with automatic reset occurring at 135–155 °C. Continuous operation above 125 °C ambient requires thermal design validation using Rth(JC) = 2 °C/W and proper PCB copper area per DS4361 recommendations.
Can VN330SP-E drive inductive loads without external flyback diodes?
Yes-the device includes fast demagnetization capability delivering Vdemag down to VCC−65 V, which safely dissipates stored inductive energy without external diodes. This is confirmed in Figure 6 waveforms and Table 4 specifications for VCC = 24 V and LLOAD ≥ 1 mH.
How does the DIAG pin indicate different fault conditions?
DIAG pulls low for overtemperature, undervoltage, or short-circuit events. The truth table (Table 7) shows DIAG = L during overtemperature and undervoltage, and H during normal operation or current-limited short-circuit-enabling firmware to distinguish between thermal and electrical faults via timing analysis.
Is VN330SP-E compatible with 3.3 V microcontroller GPIOs?
Yes-input high level is defined at VIH = 3.5 V min, making it compatible with 3.3 V logic when driven with sufficient drive strength (IIN ≤ 600 µA). No level-shifting is required, though noise immunity improves with 5 V logic due to 0.5 V hysteresis (VI(HYST)).
