Product details
Overview
VTVS11GSMF-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 of low-voltage DC lines. It features 11.2 V maximum stand-off voltage (VRWM), 12.99–13.52 V reverse breakdown voltage (VBR) at 1 mA, 21.75 A peak pulse current (IPPM) under 10/1000 μs waveform, and clamps to ≤18.0 V at rated current - deployed in automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS11GSMF-M3-18 datasheet, VTVS11GSMF-M3-18 pinout, VTVS11GSMF-M3-18 application, or VTVS11GSMF-M3-18 equivalent, key selection criteria include ±2 % VBR tolerance, 910 pF typical junction capacitance at 0 V, AEC-Q101 qualification status, and compatibility with SOD-123W footprint for space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified breakdown range (12.99–13.52 V). Its low-clamping behavior (VC ≤ 18.0 V at IPPM = 21.75 A) ensures downstream ICs remain within safe operating limits during transients.
It delivers ±30 kV ESD immunity per IEC 61000-4-2 (contact/air), supports wave and reflow soldering per J-STD-020 MSL level 1, and maintains stable performance across –55 °C to +175 °C junction temperature range - enabling use in under-hood automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform); sustains high-energy surges without failure in 12 V automotive supply lines |
| Stand-off Voltage (VRWM) | 11.2 V max; blocks normal operation voltage while remaining fully off until transient exceeds threshold |
| Breakdown Voltage (VBR) | 12.99–13.52 V at IT = 1 mA; ±2 % tolerance enables precise overvoltage trip point alignment |
| Clamping Voltage (VC) | ≤18.0 V at IPPM = 21.75 A; limits stress on protected ICs such as CAN transceivers or MCU I/O |
| Junction Capacitance | 910 pF at VR = 0 V, f = 1 MHz; suitable for <10 Mbps data lines but not high-speed USB or Ethernet |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2; meets stringent automotive ESD robustness requirements |
| Operating Temperature | –55 °C to +175 °C; qualified for engine control unit (ECU) and transmission control module (TCM) mounting locations |
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 | Current entry during forward conduction; tied to protected line's ground or low-side return path | Provides low-impedance path to ground during transient events; must connect directly to system ground plane |
| Cathode | Current exit during reverse-biased clamping; connected to protected signal or power rail | Acts as the "input" terminal for surge suppression; placement adjacent to IC pin minimizes inductive loop area |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VBR tolerance | Enables tighter clamping margin vs. ±5 % variants, reducing risk of false triggering or insufficient protection in 12 V systems |
| Low-profile SMF package | 1.08 mm height allows integration into ultra-thin modules like ADAS camera housings and compact ECUs |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, and ESD stress - required for ASIL-B/C subsystems |
| Halogen-free molding compound | Meets RoHS and ELV directives; eliminates corrosive halogen emissions during reflow and end-of-life recycling |
| Wave/reflow solderable | Compatible with standard SMT assembly processes up to 260 °C peak temperature; no special thermal profiling needed |
Applications
| Automotive Infotainment Power Rail | Industrial Sensor Signal Line |
|---|---|

IC Role / Device Role / Timing Role: Low-capacitance unidirectional suppressor mounted directly at transceiver power pin. Use Value: 11.2 V VRWM aligns with LIN 12 V supply; 21.75 A IPPM handles worst-case ISO 7637-2 Pulse 1/2a energy without degradation. |
Use Scenario: Suppressing commutation spikes on microcontroller GPIO driving small brushed DC motors in smart home appliances. IC Role / Device Role / Timing Role: Fast-response TVS placed between GPIO and motor driver FET gate to absorb inductive kickback. Use Value: 18.0 V VC limits gate-source voltage to safe levels for 20 V-rated logic-level MOSFETs; 175 °C TJ max supports sealed enclosure thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | ±5 % VBR tolerance (11.1–12.3 V), higher VC = 18.2 V at same IPPM, non-AEC-Q101 | Acceptable for commercial-grade consumer products but not automotive front-end modules | Select when cost sensitivity outweighs precision clamping and automotive qualification needs |
| 1.5SMC11A | Same ±5 % VBR, larger SMC (DO-214AB) package (7.1 mm × 6.2 mm), higher thermal mass | Better for high-repetition surge environments but incompatible with space-constrained SOD-123W footprints | Choose when board layout allows larger footprint and thermal dissipation is prioritized over miniaturization |
Compared with SMAJ11A and 1.5SMC11A, VTVS11GSMF-M3-18 offers tighter voltage tolerance, automotive qualification, and 60 % smaller footprint - making it optimal for next-generation compact, safety-critical automotive electronics where precision and space efficiency are mandatory.

FAQ
What is the exact reverse breakdown voltage range for VTVS11GSMF-M3-18?
The VTVS11GSMF-M3-18 has a reverse breakdown voltage (VBR) range of 12.99 V to 13.52 V at IT = 1 mA and TJ = 25 °C, with ±2 % tolerance confirmed in Vishay's official datasheet revision 2.2. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable design margins in 12 V automotive systems.
Is VTVS11GSMF-M3-18 qualified for automotive use?
Yes, VTVS11GSMF-M3-18 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and ESD per JESD22-A114. This qualification validates its suitability for automotive applications such as infotainment power rails and body control modules where reliability under thermal and electrical stress is critical.
What package type does VTVS11GSMF-M3-18 use, and is it compatible with standard SMT processes?
VTVS11GSMF-M3-18 uses the SMF (DO-219AB) package - a low-profile surface-mount case measuring 3.9 mm × 1.9 mm × 1.08 mm - and is fully compatible with standard wave and reflow soldering per J-STD-020 MSL level 1, with peak temperature support up to 260 °C. Its footprint matches SOD-123W, enabling drop-in replacement in existing designs.
How does the clamping voltage of VTVS11GSMF-M3-18 compare to its stand-off voltage?
VTVS11GSMF-M3-18 has a maximum stand-off voltage (VRWM) of 11.2 V and clamps to ≤18.0 V at its rated peak pulse current (IPPM = 21.75 A). This 6.8 V differential provides sufficient margin above VRWM to avoid false triggering during normal operation while limiting transient overvoltage to a safe level for downstream 16 V-rated ICs.
What is the junction capacitance of VTVS11GSMF-M3-18, and how does it affect signal integrity?
The VTVS11GSMF-M3-18 exhibits 910 pF typical junction capacitance at VR = 0 V and f = 1 MHz. This value makes it appropriate for protecting low-speed analog or power lines (e.g., 4–20 mA loops, LIN bus, or 12 V supply rails) but unsuitable for high-speed digital interfaces like USB 2.0 or HDMI where sub-10 pF capacitance is required to prevent signal degradation.
