Product details
Overview
VTVS5V0GSMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of 5.0 V DC power rails and signal lines. It features 6.57 V minimum and 6.84 V maximum reverse breakdown voltage at 1 mA, 5 μA maximum reverse leakage at 5.0 V stand-off, and clamps to ≤8.9 V at 43.99 A peak pulse current (10/1000 μs), enabling robust protection in automotive infotainment USB ports.
For engineers reviewing the VTVS5V0GSMF-HM3-18 datasheet, VTVS5V0GSMF-HM3-18 pinout, VTVS5V0GSMF-HM3-18 application, or VTVS5V0GSMF-HM3-18 equivalent, key selection criteria include ±2 % VBR tolerance, 30 kV IEC 61000-4-2 contact/air discharge rating, halogen-free SOD-123W-compatible SMF package, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a unidirectional avalanche diode with precise 5.0 V working voltage and tight ±2 % breakdown voltage tolerance, ensuring consistent clamping behavior across temperature and production lots. Its low 20 K/W junction-to-lead thermal resistance supports reliable power dissipation during repetitive transients.
The SMF package delivers 1.08 mm height and 3.9 mm × 1.9 mm footprint-compatible with SOD-123W, SOD-123F, and SOD-123FL land patterns-while maintaining MSL level 1 moisture sensitivity and peak reflow tolerance up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 6.57 V / 6.84 V at IT = 1 mA - ensures accurate 5.0 V rail clamping with minimal overvoltage margin |
| VRWM | 5.00 V - maximum continuous reverse voltage before significant leakage begins |
| IR @ VRWM | 5 μA - ultra-low leakage preserves system power budget in always-on circuits |
| IPPM | 43.99 A (10/1000 μs) - sustains high-energy surges without failure in automotive load-dump scenarios |
| VC @ IPPM | ≤8.9 V - limits protected IC voltage stress below typical 12 V logic I/O absolute maximum ratings |
| CD @ 0 V | 2095 pF - optimized for DC power rail protection; not suitable for high-speed data lines |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 immunity requirements for automotive ECUs |
Pinout & Package
Package: SMF (DO-219AB), low-profile surface-mount case compatible with SOD-123W footprint; dimensions 3.9 mm × 1.9 mm × 1.08 mm; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of protection path | Connected to protected line (e.g., VBUS); conducts during reverse transient to shunt energy to ground |
| Cathode | Output side of protection path | Connected to system ground; establishes unidirectional clamping polarity for positive-going transients |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Handles 10/1000 μs surges up to 43.99 A without degradation-meets ISO 7637-2 Pulse 1/2b/5a requirements |
| ±2 % VBR tolerance | Enables tighter design margins than ±5 % variants (e.g., VTVS5V0ASMF), reducing risk of premature conduction or inadequate clamping |
| AEC-Q101 qualified | Validated for automotive under-hood and cabin applications per stress test conditions including HTOL, TCT, and ESD |
| Halogen-free & RoHS-compliant | Meets automotive material compliance standards (JIS C 0950, IEC 61249-2-21) and supports lead-free reflow assembly |
| Low-noise fast response | Sub-nanosecond turn-on time prevents ESD-induced latch-up in sensitive microcontrollers and transceivers |
Applications
| Automotive USB Power Port Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protecting 5 V USB VBUS lines in vehicle infotainment head units against load dump and ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VBUS and chassis ground to clamp transients before reaching USB controller IC. Use Value: Maintains VBUS <8.9 V during 43.99 A surges, preventing damage to USB PHY and preserving communication integrity per USB 2.0 electrical specs. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA transmitter) from induced surges in factory automation PLC modules. IC Role / Device Role / Timing Role: Standoff protector on sensor output node, conducting only when voltage exceeds 5.0 V to divert energy away from precision DAC and op-amp circuitry. Use Value: Limits transient overshoot to ≤8.9 V, avoiding saturation or input-stage damage in instrumentation amplifiers with ±15 V supply rails. |
| Automotive Body Control Module (BCM) CAN Interface | Consumer Appliance DC Power Input Stage |
Use Scenario: Secondary protection on 5 V supply rail feeding CAN transceivers in BCMs exposed to battery line transients. IC Role / Device Role / Timing Role: Bulk transient suppressor upstream of local LDO regulators, absorbing energy before it reaches noise-sensitive CAN PHY power domains. Use Value: Withstands repeated 400 W pulses while maintaining ≤5 μA leakage-preserving LDO efficiency and minimizing thermal drift in CAN bus timing. |
Use Scenario: Overvoltage suppression on 5 V DC input of smart home hubs powered by wall adapters subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary clamping device on main 5 V rail, activated before fuse or polyfuse trips, ensuring uninterrupted operation during transient events. Use Value: Clamps to ≤8.9 V within nanoseconds, protecting MCU, Wi-Fi SoC, and memory from destructive overvoltage without requiring system reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | ±5 % VBR (6.4–7.0 V), same SMF package, 400 W rating, non-AEC-Q101 | Lacks automotive qualification; higher VBR spread increases risk of false triggering or insufficient clamping in tight-margin designs | Select when cost sensitivity outweighs automotive reliability requirements and ±5 % tolerance is acceptable |
| VTVS5V0ASMF-HM3-18 | ±5 % VBR (6.4–7.0 V), identical package and power rating, AEC-Q101 qualified | Same automotive qualification but looser breakdown tolerance reduces design confidence for 5.0 V systems near absolute maximum ratings | Choose when legacy design validation used ±5 % variant and no redesign is permitted |
Compared with SMAJ5.0A and VTVS5V0ASMF-HM3-18, the VTVS5V0GSMF-HM3-18 provides superior voltage accuracy (±2 %) and guaranteed automotive qualification-critical for new designs targeting ASIL-B functional safety zones where predictable clamping behavior directly impacts fault coverage metrics.

The VTVS5V0GSMF-HM3-18 has a reverse breakdown voltage range of 6.57 V to 6.84 V at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % VBR tolerance. This tight specification ensures consistent clamping performance across production lots and temperature ranges, making VTVS5V0GSMF-HM3-18 suitable for precision 5.0 V rail protection where overvoltage margin is critical.
Is VTVS5V0GSMF-HM3-18 qualified for automotive applications?
Yes, VTVS5V0GSMF-HM3-18 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD. This qualification confirms its suitability for automotive under-hood and cabin applications such as infotainment power rails and BCM 5 V supplies, where reliability under thermal and electrical stress is essential.
What package type does VTVS5V0GSMF-HM3-18 use, and is it compatible with standard footprints?
VTVS5V0GSMF-HM3-18 uses the SMF (DO-219AB) package-a low-profile surface-mount case measuring 3.9 mm × 1.9 mm × 1.08 mm-with cathode marking on the top surface. It is fully compatible with SOD-123W, SOD-123F, and SOD-123FL land patterns, enabling drop-in replacement in existing layouts without PCB redesign.
How does the clamping voltage of VTVS5V0GSMF-HM3-18 compare to its stand-off voltage?
VTVS5V0GSMF-HM3-18 has a stand-off voltage (VRWM) of 5.00 V and a maximum reverse clamping voltage (VC) of 8.9 V at 43.99 A peak pulse current. This 3.9 V differential ensures safe operation below the 12 V absolute maximum rating of most 5 V logic ICs while providing sufficient margin to avoid false triggering during normal 5.0 V rail fluctuations.
What is the ESD protection capability of VTVS5V0GSMF-HM3-18 per IEC 61000-4-2?
VTVS5V0GSMF-HM3-18 delivers ±30 kV contact discharge and ±30 kV air discharge protection per IEC 61000-4-2, exceeding Level 4 requirements. This performance is achieved through "low-noise" fast-response avalanche technology, allowing VTVS5V0GSMF-HM3-18 to suppress ESD events before they propagate into downstream ICs such as USB transceivers or CAN controllers.
