Product details
Overview
VTVS5V0GSMF-HM3-08 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 I/O 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). Used in automotive infotainment USB ports and industrial sensor interfaces.
For engineers reviewing the VTVS5V0GSMF-HM3-08 datasheet, VTVS5V0GSMF-HM3-08 pinout, VTVS5V0GSMF-HM3-08 application, or VTVS5V0GSMF-HM3-08 equivalent, key selection criteria include ±2 % VBR tolerance, halogen-free SOD-123W-compatible SMF package, IEC 61000-4-2 ±30 kV contact/air discharge compliance, and 175 °C max junction temperature capability.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds its precisely specified VBR window (6.57–6.84 V). Its low dynamic impedance enables fast response (<1 ns) and stable clamping at 8.9 V under 43.99 A 10/1000 μs surge, minimizing stress on downstream ICs.
The SMF package (DO-219AB) provides 1.08 mm height and 3.9 × 1.9 mm footprint, optimized for high-density PCB layouts and compatible with standard SOD-123W reflow profiles (peak 260 °C). Thermal resistance RthJL is 20 K/W to leads, supporting sustained operation up to TJ = +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.57 V / 6.84 V at IT = 1 mA - tight ±2 % tolerance ensures predictable turn-on across temperature and production lot |
| VRWM | 5.00 V - maximum continuous reverse working voltage; safe for 5 V rail protection without leakage-induced power loss |
| IR @ VRWM | 5 μA - ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| IPPM | 43.99 A (10/1000 μs) - delivers 400 W peak pulse power handling for IEC 61000-4-5 Level 4 surges |
| VC @ IPPM | ≤8.9 V - clamping voltage margin of 3.9 V above VRWM protects 5 V logic inputs meeting IEC 61000-4-2 |
| CD @ 0 V | 2095 pF - capacitance value suitable for low-speed data lines (e.g., UART, CAN, LIN) but not high-speed USB 2.0 |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds automotive and industrial immunity requirements |
Pinout & Package
SMF (DO-219AB) package: low-profile surface-mount case with cathode bar marking; dimensions 3.9 mm × 1.9 mm × 1.08 mm; compatible with SOD-123W, SOD-123F, and SOD-123FL footprints; halogen-free molding compound (UL 94 V-0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of protected line | Connected to signal/power source; carries surge current into diode during overvoltage event |
| Cathode | Clamp reference node | Connected to ground or lower-potential rail; defines clamping threshold relative to this node |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VBR tolerance | Enables precise overvoltage threshold setting for 5 V systems, reducing design margin uncertainty vs. ±5 % variants |
| 400 W peak pulse power (10/1000 μs) | Withstands repeated lightning-induced surges per IEC 61000-4-5 without degradation |
| IEC 61000-4-2 ±30 kV ESD protection | Eliminates need for additional ESD stages on board-level interfaces like USB, RS-485, or sensor analog outputs |
| Low-noise fast-response technology | Sub-nanosecond response time prevents ESD energy coupling into sensitive analog or RF circuitry |
| AEC-Q101 qualified option available | Supports automotive-grade reliability validation (not inherent to -HM3-08 suffix, but part family offers qualified versions) |
Applications
| Automotive USB Port Protection | Industrial Sensor Signal Line Clamp |
|---|---|
|
Use Scenario: Protecting USB 2.0 D+/D− lines in vehicle infotainment head units against hot-plug transients and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS clamp referenced to system ground, placed adjacent to connector. Use Value: Maintains signal integrity below 2095 pF while clamping to ≤8.9 V, preventing damage to USB transceivers rated for 5.5 V absolute max. |
Use Scenario: Safeguarding 4–20 mA current-loop analog outputs of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role / Timing Role: Standoff-mode protector on loop supply line, absorbing induced surges from nearby motor switching. Use Value: Withstands 43.99 A surges without latch-up, preserving loop accuracy and avoiding false trips in safety-critical monitoring. |
| 5 V Power Rail Surge Suppression | RS-485 Transceiver I/O Protection |
|
Use Scenario: Secondary overvoltage protection on 5 V microcontroller power input after primary DC/DC converter. IC Role / Device Role / Timing Role: Fast-acting shunt device that diverts surge current away from MCU VDD pins during load dump events. Use Value: Clamps 400 W surges within 1 ns, limiting voltage excursion to 8.9 V and preventing brownout or internal latch-up. |
Use Scenario: Board-level ESD hardening of RS-485 transceiver A/B differential lines in building control networks. IC Role / Device Role / Timing Role: Dual unidirectional TVS pair (one per line) referenced to common ground, placed before transceiver inputs. Use Value: Provides ±30 kV IEC 61000-4-2 immunity without degrading signal edge rate due to controlled 2095 pF loading. |
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, 9.2 V clamping at 42.95 A | Looser VBR tolerance increases risk of premature conduction in precision 5 V systems | Select when cost sensitivity outweighs tight threshold control; verify clamping margin with worst-case VBR min |
| 1.5SMC5.0A | DO-214AB (SMC) package, 1.75 mm height, 7.0 mm × 6.2 mm footprint, 400 W rating, 9.2 V clamping | Larger footprint incompatible with space-constrained layouts; higher thermal mass slows response slightly | Choose only if board layout allows larger package and higher mounting height; not drop-in replacement |
Compared with VTVS5V0GSMF-HM3-08, SMAJ5.0A trades tighter voltage control for broader availability, while 1.5SMC5.0A sacrifices miniaturization for higher thermal mass-neither matches the combination of ±2 % tolerance, SMF footprint, and 2095 pF capacitance in this Vishay device.

FAQ
What is the exact reverse breakdown voltage range for VTVS5V0GSMF-HM3-08?
The VTVS5V0GSMF-HM3-08 has a guaranteed 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 behavior across production lots and supports reliable 5 V system protection without excessive design margin.
Is VTVS5V0GSMF-HM3-08 RoHS-compliant and halogen-free?
Yes, VTVS5V0GSMF-HM3-08 is RoHS-compliant and halogen-free, as confirmed by Vishay's material categorization documentation (www.vishay.com/doc?99912). The SMF package uses UL 94 V-0 rated halogen-free molding compound, meeting IPC-1752A Class 3 requirements for environmentally conscious electronics manufacturing.
Does VTVS5V0GSMF-HM3-08 meet automotive qualification standards?
VTVS5V0GSMF-HM3-08 belongs to the Vishay eSMP® Series, which offers AEC-Q101 qualified variants. While the -HM3-08 suffix indicates halogen-free and lead-free terminations, AEC-Q101 qualification is optional and denoted separately (e.g., with "-AQ" suffix); confirm qualification status via Vishay's official product change notices or datasheet revision history for VTVS5V0GSMF-HM3-08.
What is the maximum clamping voltage of VTVS5V0GSMF-HM3-08 under surge conditions?
The maximum reverse clamping voltage (VC) of VTVS5V0GSMF-HM3-08 is 8.9 V at IPPM = 43.99 A with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during worst-case surge events, ensuring compatibility with 5 V logic interfaces.
Can VTVS5V0GSMF-HM3-08 be used for bidirectional signal line protection?
No, VTVS5V0GSMF-HM3-08 is a unidirectional TVS diode and must be used with correct polarity-cathode to ground-to protect positive-going transients on 5 V lines. For bidirectional protection (e.g., AC-coupled data lines), a dual-diode configuration or dedicated bidirectional TVS such as VTVS5V0BGS-M3-08 is required; using VTVS5V0GSMF-HM3-08 in reverse orientation risks permanent failure.
