Product details
Overview
VTVS10GSMF-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 11.81 V minimum / 12.30 V maximum reverse breakdown voltage at 1 mA, 10.30 V stand-off voltage, 23.98 A peak pulse current (10/1000 μs), and clamps to ≤16.3 V under full-rated surge.
For engineers reviewing the VTVS10GSMF-M3-18 datasheet, VTVS10GSMF-M3-18 pinout, VTVS10GSMF-M3-18 application, or VTVS10GSMF-M3-18 equivalent, this device delivers ±2 % VBR tolerance, ±30 kV IEC 61000-4-2 ESD immunity, and halogen-free construction - critical for automotive-grade signal line hardening and industrial interface robustness.
Technical Context
This TVS diode operates unidirectionally with a 10.30 V working voltage and clamps transients to 16.3 V at 23.98 A, enabling reliable protection of 12 V nominal systems without false triggering. Its 1.08 mm height and SOD-123W-compatible SMF (DO-219AB) footprint supports high-density PCB layouts while maintaining thermal resistance of 20 K/W to leads.
The device achieves <1 ns response time via "Low-Noise" avalanche technology and sustains 175 °C junction temperature, meeting AEC-Q101 qualification requirements when specified. Capacitance is 988 pF at 0 V, optimized for low-speed data and power rail protection rather than high-frequency signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform) - handles common lightning-induced surges per IEC 61000-4-5 Level 3. |
| Reverse Breakdown Voltage | 11.81–12.30 V @ 1 mA - tight ±2 % tolerance ensures precise trigger margin above 12 V system rails. |
| Stand-off Voltage | 10.30 V max - prevents conduction during normal 12 V operation while allowing headroom for ripple. |
| Clamping Voltage | ≤16.3 V @ 23.98 A - limits downstream IC stress to safe levels during full-rated transient events. |
| ESD Immunity | ±30 kV contact / air discharge (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements. |
| Junction Temperature Range | −55 °C to +175 °C - supports under-hood automotive and industrial ambient environments. |
| Package | SMF (DO-219AB) - industry-standard low-profile surface-mount outline compatible with SOD-123W reflow profiles. |
Pinout & Package
SMF (DO-219AB) package: 2-terminal unidirectional device with cathode marked by bar on top surface. Dimensions: 3.9 × 1.9 × 1.08 mm (L × W × H); recommended footprint per Vishay S8-V-3915.01-001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path | Connected to ground or low-impedance reference; completes clamping loop during overvoltage events. |
| Cathode | Protected line connection | Connected to the line being protected (e.g., CAN_H, LIN, sensor supply); blocks reverse leakage below VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VBR tolerance | Enables tighter design margins for 12 V systems versus ±5 % variants, reducing risk of premature conduction. |
| 400 W peak pulse rating | Supports IEC 61000-4-5 surge testing up to 1 A (2 Ω source) without degradation. |
| Halogen-free molding compound | Meets JESC Q00101 and RoHS Directive 2011/65/EU for environmentally compliant manufacturing. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking - simplifies SMT production logistics. |
| AEC-Q101 qualified option | Available in HM3-18 variant; VTVS10GSMF-M3-18 shares identical electrical specs but lacks automotive qualification. |
Applications
| Automotive Sensor Interface | Industrial 12 V Power Rail |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, or position sensors in engine control modules. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between sensor output and ECU input to absorb load dump and ISO 7637-2 pulses. Use Value: Prevents latch-up or damage to precision op-amps and ADC front-ends during 12 V system transients. |
Use Scenario: Safeguarding 12 V supply inputs to PLC I/O modules, motor drivers, and relay controllers. IC Role / Device Role / Timing Role: Primary surge suppression device across input terminals, coordinated with upstream fuses and filters. Use Value: Limits voltage excursion to ≤16.3 V during 400 W surges, preserving MOSFET gate oxide integrity and MCU brown-out thresholds. |

Use Scenario: ESD protection for D+ and D− lines in embedded USB host/device ports exposed to user handling. IC Role / Device Role / Timing Role: Low-capacitance (988 pF) unidirectional clamp referenced to VSS, placed adjacent to connector. Use Value: Withstands ±30 kV contact discharge without signal distortion or bit errors in full-speed (12 Mbps) operation. |
Use Scenario: Transient suppression on LIN bus master/slave nodes in body electronics (door modules, seat controls). IC Role / Device Role / Timing Role: Standoff voltage (10.30 V) aligns with LIN's 12 V nominal supply; clamps fast spikes from relay switching noise. Use Value: Maintains bus communication integrity during load dump events by limiting voltage overshoot within LIN physical layer spec limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | ±5 % VBR (10.5–11.6 V), 400 W, SMA package (DO-214AC), 2.5 mm height | Higher profile and looser tolerance; less suitable for space-constrained automotive modules | Select when cost sensitivity outweighs board space and precision requirements. |
| SMF10A | ±5 % VBR (10.5–11.6 V), 400 W, SMF package, same footprint but wider tolerance band | Same package but lacks ±2 % precision; not rated for AEC-Q101 even in HM3 variant | Choose for non-automotive industrial use where tighter VBR control is unnecessary. |
Compared with SMAJ10A and SMF10A, VTVS10GSMF-M3-18 provides superior voltage accuracy and lower profile for automotive and high-reliability designs, though it requires verification of ±2 % tolerance impact on system-level margin analysis.

FAQ
What is the clamping voltage of VTVS10GSMF-M3-18 at its rated peak pulse current?
The VTVS10GSMF-M3-18 clamps to a maximum of 16.3 V at its rated peak pulse current of 23.98 A (10/1000 μs waveform). This value is measured per standard test conditions in the Vishay datasheet (Document Number: 85891, Rev. 2.2) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The VTVS10GSMF-M3-18 maintains this clamping performance across its full operating temperature range.
Is VTVS10GSMF-M3-18 AEC-Q101 qualified?
No, VTVS10GSMF-M3-18 is not AEC-Q101 qualified. The AEC-Q101 qualified version is designated as VTVS10GSMF-HM3-18, which includes additional automotive reliability testing. The VTVS10GSMF-M3-18 shares identical electrical specifications and packaging but lacks the qualification documentation and screening required for automotive under-hood applications. Engineers must select the HM3 suffix variant for AEC-Q101 compliance.
What does the "G" in VTVS10GSMF-M3-18 indicate?
The "G" in VTVS10GSMF-M3-18 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffixed parts (e.g., VTVS10ASMF-M3-18) that specify ±5 % tolerance. Per Vishay's ordering table, VTVS10GSMF has a VBR range of 11.81 V to 12.30 V at 1 mA, enabling tighter design margins in 12 V systems. This tolerance grade is confirmed in the Electrical Characteristics table on page 3 of document 85891.
Can VTVS10GSMF-M3-18 be used in bidirectional configurations?
No, VTVS10GSMF-M3-18 is a unidirectional TVS diode and must be used with correct polarity: cathode toward the protected line, anode to ground. It does not provide symmetrical clamping for AC or bidirectional signals. For bidirectional protection, Vishay offers separate dual-diode configurations (e.g., VTVS10Bxx series) or discrete back-to-back arrangements - the VTVS10GSMF-M3-18 itself functions only in one direction and will conduct heavily if reverse-biased beyond its stand-off voltage.
What is the moisture sensitivity level (MSL) rating for VTVS10GSMF-M3-18?
VTVS10GSMF-M3-18 has a Moisture Sensitivity Level (MSL) rating of Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions (<30 °C / 85 % RH) without baking prior to reflow soldering. This is confirmed in the Package Data section (page 2) of Vishay document 85891. The MSL Level 1 rating simplifies manufacturing flow and eliminates pre-bake steps for VTVS10GSMF-M3-18 in standard SMT assembly.
