Product details
Overview
VTVS17GSMF-M3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection on low-voltage DC lines such as USB, HDMI, and automotive sensor interfaces. It features 16.9 V maximum stand-off voltage (VRWM), 19.6–20.4 V reverse breakdown voltage (VBR) at 1 mA, 28 V clamping voltage (VC) at 14.21 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS17GSMF-M3-18 datasheet, VTVS17GSMF-M3-18 pinout, VTVS17GSMF-M3-18 application, or VTVS17GSMF-M3-18 equivalent, key selection criteria include its ±2 % VBR tolerance, 606 pF junction capacitance at 0 V, 175 °C max junction temperature, and compatibility with SOD-123W footprint for high-density PCB layouts.
Technical Context
The VTVS17GSMF-M3-18 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 19.6–20.4 V breakdown range to clamp transients to ≤28 V at 14.21 A (10/1000 μs). Its low-noise architecture enables sub-nanosecond response time, critical for protecting high-speed digital interfaces without signal distortion.
Thermally, it delivers 20 K/W junction-to-lead thermal resistance and supports continuous operation from –55 °C to +175 °C. The SMF package's halogen-free molding compound, MSL level 1 rating, and 260 °C reflow compatibility ensure robust manufacturability in automotive and industrial assembly lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform - sustains automotive load-dump and ISO 7637-2 transient suppression) |
| Stand-off Voltage (VRWM) | 16.9 V max - blocks normal 15 V rail operation while remaining inactive until overvoltage occurs |
| Breakdown Voltage (VBR) | 19.6–20.4 V at IT = 1 mA, ±2 % tolerance - ensures precise, repeatable turn-on across production lots |
| Clamping Voltage (VC) | 28 V at IPPM = 14.21 A - limits downstream IC stress below safe operating thresholds of 3.3 V/5 V logic |
| Junction Capacitance (CD) | 606 pF at VR = 0 V, f = 1 MHz - compatible with USB 2.0 and CAN FD data rates without excessive signal attenuation |
| ESD Rating | ±30 kV contact & air discharge per IEC 61000-4-2 - meets Level 4 system-level ESD immunity requirements |
| Operating Temperature | –55 °C to +175 °C - qualified for under-hood automotive and industrial power supply environments |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-impedance return path; defines clamping reference for unidirectional operation |
| Cathode | Protected line input | Connected to signal/power line requiring protection; conducts avalanche current during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VBR tolerance | Enables tighter clamping window vs. ±5 % variants, reducing margin uncertainty in safety-critical 12–24 V systems |
| Low-profile SMF package | 1.08 mm height allows placement beneath connectors and in space-constrained modules like ADAS camera housings |
| Halogen-free & RoHS-compliant | Meets automotive ELV directive and IPC-1752A material declaration requirements for Tier 1 supply chains |
| AEC-Q101 qualified option available | Supports qualification-ready BOMs for automotive ECUs without additional reliability testing overhead |
| "Low-Noise" fast response | Sub-1 ns turn-on time prevents ESD-induced latch-up in CMOS interface ICs such as USB transceivers and LIN controllers |
Applications
| Automotive Sensor Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control units exposed to ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between sensor signal line and chassis ground. Use Value: Clamps 14.21 A transients to 28 V, preserving signal integrity of 16.9 V-rated sensors and preventing MCU input damage. |
Use Scenario: ESD protection on D+ and D− lines of USB 2.0 ports in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance TVS placed directly at connector entry point. Use Value: 606 pF capacitance avoids signal rise-time degradation while delivering ±30 kV IEC 61000-4-2 compliance. |

Use Scenario: Secondary protection on CAN FD physical layer (PHY) transceivers operating at 5 Mbps in factory automation PLCs. IC Role / Device Role / Timing Role: Standoff-clamp TVS on CANH/CANL differential pair, referenced to common-mode ground. Use Value: 28 V clamping ensures PHY remains within absolute maximum ratings during coupled surge events on long cable runs. |
Use Scenario: Input-stage surge suppression on 12 V auxiliary power rails feeding motor drivers or display backlights. IC Role / Device Role / Timing Role: Primary unidirectional TVS on positive rail before DC/DC converter input. Use Value: 400 W peak power rating handles 10/1000 μs load dump surges up to 14.21 A without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | ±5 % VBR tolerance (16.2–17.8 V), 300 W PPPM, 33.2 V VC at 12.3 A | Lower clamping voltage margin and reduced surge handling - suitable only for non-automotive consumer-grade 12 V rails | Select when cost sensitivity outweighs precision clamping and AEC-Q101 compliance requirements |
| TPSMD17A | ±5 % VBR, 400 W PPPM, 27.6 V VC at 14.5 A, SMC (DO-214AB) package (7.1 mm × 6.2 mm) | Larger footprint incompatible with space-constrained designs; higher thermal mass delays response slightly | Choose when board layout permits larger package and higher thermal inertia is acceptable for slower transients |
Compared with SMAJ17A and TPSMD17A, the VTVS17GSMF-M3-18 provides tighter ±2 % VBR control, lower profile, and verified compatibility with high-speed interfaces - making it optimal for automotive and compact industrial electronics where precision clamping and layout density are critical.

FAQ
What is the exact reverse breakdown voltage range for VTVS17GSMF-M3-18?
The VTVS17GSMF-M3-18 has a reverse breakdown voltage (VBR) range of 19.6 V to 20.4 V at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % tolerance grade. This precise window ensures predictable clamping behavior in 12–16 V systems and is confirmed in Vishay's Rev. 2.2 datasheet (Document Number: 85891) Table on page 3.
Is VTVS17GSMF-M3-18 AEC-Q101 qualified?
The VTVS17GSMF-M3-18 itself is not explicitly marked as AEC-Q101 qualified in the provided documentation; however, the VTVS17GSMF family offers an AEC-Q101 qualified variant (e.g., VTVS17GSMF-HM3-18). For automotive applications requiring formal qualification, that variant should be specified - VTVS17GSMF-M3-18 is suitable for industrial and commercial use with identical electrical specs.
What does the "-M3-18" suffix indicate in VTVS17GSMF-M3-18?
The "-M3-18" suffix denotes tape-and-reel packaging: "M3" specifies 3 k per 7″ reel (8 mm tape), and "-18" indicates RoHS-compliant, lead (Pb)-free, tin-plated terminations with halogen-free molding compound. This matches Vishay's ordering code convention defined in the "Ordering Information" section of the datasheet.
Can VTVS17GSMF-M3-18 be used for bidirectional protection?
No - VTVS17GSMF-M3-18 is a unidirectional TVS diode, intended only for circuits with defined polarity such as DC power rails or single-ended data lines. For bidirectional applications like AC lines or differential buses requiring symmetrical clamping, a dedicated bidirectional part (e.g., VTVS17B) must be selected instead.
What is the thermal resistance and maximum junction temperature of VTVS17GSMF-M3-18?
The VTVS17GSMF-M3-18 has a junction-to-lead thermal resistance (RthJL) of 20 K/W when mounted on an infinite heat sink, and a maximum junction temperature (TJ) rating of +175 °C. These values enable reliable operation in under-hood automotive environments and high-ambient industrial enclosures without derating at full 400 W pulse power.
