Product details
Overview
VTVS11GSMF-M3-08 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 low-voltage DC lines such as USB, HDMI, and automotive sensor interfaces. It features 11.2 V maximum stand-off voltage (VRWM), 12.99–13.52 V reverse breakdown voltage (VBR) at 1 mA, 18.0 V maximum clamping voltage (VC) at 21.75 A peak pulse current (IPPM), and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS11GSMF-M3-08 datasheet, VTVS11GSMF-M3-08 pinout, VTVS11GSMF-M3-08 application, or VTVS11GSMF-M3-08 equivalent, key selection criteria include its ±2 % VBR tolerance, 910 pF typical junction capacitance at 0 V, 175 °C max junction temperature, halogen-free construction, and compatibility with SOD-123W footprint for space-constrained PCB layouts.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its precisely specified breakdown range (12.99–13.52 V), then clamping transients to ≤18.0 V at 21.75 A (10/1000 μs waveform). Its low 910 pF capacitance minimizes signal distortion on high-speed data lines up to ~100 MHz.
Designed for surface-mount reflow and wave soldering, it meets AEC-Q101 qualification requirements and delivers ±30 kV contact/air discharge ESD protection per IEC 61000-4-2 - critical for automotive infotainment and ADAS sensor interfaces where robustness and reliability are non-negotiable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Automotive Sensor Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine bay modules exposed to ISO 7637-2 pulses and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between signal line and chassis ground to clamp transients before reaching MCU ADC input or LIN transceiver. Use Value: Maintains 11.2 V stand-off while clamping to ≤18.0 V, preventing latch-up or damage to 12 V-rated automotive microcontrollers. |
Use Scenario: Safeguarding D+ and D− lines of USB 2.0 ports in infotainment head units against hot-plug ESD and cable-induced surges. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional VTVS11GSMF-M3-08 used per line with cathode to ground, leveraging low 910 pF capacitance. Use Value: Preserves signal integrity up to 480 Mbps with minimal rise-time degradation due to sub-1 ns response and controlled capacitance. |
| Industrial CAN FD Node | Power Supply Rail Clamp |
Use Scenario: Secondary protection on CAN FD physical layer (e.g., near connector) in factory automation controllers subjected to long-cable induced transients. IC Role / Device Role / Timing Role: Standoff-aligned TVS (11.2 V VRWM) placed across CANH–GND and CANL–GND to absorb common-mode surges without affecting differential signaling. Use Value: Clamps to 18.0 V within nanoseconds, protecting ISO 11898-2 compliant transceivers rated for 40 V absolute max while maintaining bit-rate fidelity. |
Use Scenario: Input rail protection for 12 V DC-DC converters in telecom power supplies facing lightning-induced surges per IEC 61000-4-5 Level 3. IC Role / Device Role / Timing Role: Primary transient suppressor on VIN line, coordinated with upstream fuse and downstream ceramic capacitor to limit let-through energy. Use Value: 400 W peak power rating handles 10/1000 μs surges up to 21.75 A, enabling robust front-end protection without thermal runaway at 175 °C TJ max. |
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 (11.1–12.3 V), 200 W PPPM, 1000 pF CD, SMA package (larger than SMF) | Limited to lower-energy transients; less suitable for automotive AEC-Q101 systems or high-density layouts | Select when cost sensitivity outweighs precision clamping and board space constraints |
| TPSMF11A | ±5 % VBR, same 400 W PPPM and SMF package, but not AEC-Q101 qualified; 950 pF CD | Acceptable for industrial consumer gear, but excluded from automotive Tier-1 BOMs requiring AEC-Q101 validation | Choose for non-automotive applications where qualification documentation is not mandated |
Compared with SMAJ11A and TPSMF11A, VTVS11GSMF-M3-08 offers tighter ±2 % breakdown tolerance, guaranteed AEC-Q101 qualification, and identical 400 W surge rating in a smaller SMF footprint - making it the preferred choice for next-generation automotive and high-reliability industrial designs demanding precision and compliance.
