Product details
Overview
VTVS40GSMF-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 infotainment interfaces. It features 39.6 V stand-off voltage (VRWM), 46.11–48.00 V reverse breakdown (VBR at IT = 1 mA), 67 V maximum clamping voltage (VC) at 5.87 A peak pulse current (IPPM), and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS40GSMF-M3-08 datasheet, VTVS40GSMF-M3-08 pinout, VTVS40GSMF-M3-08 application, or VTVS40GSMF-M3-08 equivalent, key selection criteria include its ±2 % VBR tolerance, 309 pF 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, triggered when reverse voltage exceeds its precisely specified breakdown range (46.11–48.00 V). Its low clamping ratio (VC/VBR ≈ 1.41) ensures robust overvoltage suppression during 10/1000 μs transients while limiting stress on downstream ICs.
Designed for surface-mount reflow and wave soldering, it meets MSL level 1 per J-STD-020, supports peak temperatures up to 260 °C, and delivers stable performance across -55 °C to +175 °C operating range - making it suitable for under-hood automotive and industrial environments where thermal cycling is severe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 39.6 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 3.3 V/5 V/12 V rail protection. |
| Breakdown Voltage (VBR) | 46.11–48.00 V at IT = 1 mA, ±2 % tolerance - tight regulation enables precise trigger threshold for sensitive interface protection. |
| Clamping Voltage (VC) | 67 V at IPPM = 5.87 A (10/1000 μs) - limits transient voltage seen by protected ICs to within safe absolute maximum ratings. |
| Peak Pulse Power (PPP) | 400 W - sustains high-energy surges (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure in automotive and industrial applications. |
| Junction Capacitance (CD) | 309 pF at VR = 0 V, f = 1 MHz - optimized for signal integrity in high-speed data lines like USB 2.0 and CAN FD, minimizing insertion loss. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 requirements, eliminating need for external ESD staging in consumer and automotive ECUs. |
| Package | SMF (DO-219AB), 3.9 × 1.9 × 1.08 mm - ultra-low-profile SMD footprint compatible with SOD-123W land pattern, enabling dense board layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ40A-E3/52 (Vishay) | Higher VRWM (40.0 V), higher VC (64.5 V), SMB package (4.5 × 3.9 × 2.3 mm) | Larger footprint; better suited for higher-power 1 kW surge standards (IEC 61000-4-5), less optimal for high-density layouts | Select when higher surge energy handling is required and board space permits larger package. |
| TPSMA6.8A (Texas Instruments) | Lower VRWM (6.8 V), lower VBR (7.6–8.4 V), same SMF package, 600 W PPP | Targeted at 5 V logic rails; not interchangeable due to mismatched voltage rating for 39.6 V standoff requirement | Use only for lower-voltage interfaces; VTVS40GSMF-M3-08 remains necessary for 24–48 V system protection. |
Compared with SMBJ40A-E3/52, VTVS40GSMF-M3-08 offers 35 % smaller footprint and 1.08 mm height for space-critical designs, while delivering identical 400 W surge capability. Against TPSMA6.8A, it provides 5.8× higher VRWM - essential for protecting 24 V industrial sensors and automotive body control modules.

FAQ
What is the exact reverse breakdown voltage range for VTVS40GSMF-M3-08?
The VTVS40GSMF-M3-08 has a reverse breakdown voltage (VBR) of 46.11 V minimum to 48.00 V maximum at IT = 1 mA and TJ = 25 °C, with ±2 % tolerance. This tight specification ensures consistent clamping behavior across production lots and supports precise system-level surge margin analysis in designs using VTVS40GSMF-M3-08.
Is VTVS40GSMF-M3-08 suitable for automotive applications?
VTVS40GSMF-M3-08 is RoHS-compliant, halogen-free, and rated for -55 °C to +175 °C operation - meeting baseline environmental requirements for automotive under-hood use. While the standard M3-08 variant is not AEC-Q101 qualified, the HM3-08 variant (VTVS40GSMF-HM3-08) is AEC-Q101 qualified and shares identical electrical specs with VTVS40GSMF-M3-08.
What is the maximum clamping voltage of VTVS40GSMF-M3-08 under surge conditions?
The maximum reverse clamping voltage (VC) of VTVS40GSMF-M3-08 is 67 V at a peak pulse current (IPPM) of 5.87 A with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during standardized surge events and is critical for ensuring downstream ICs remain within their absolute maximum ratings when VTVS40GSMF-M3-08 is deployed.
Does VTVS40GSMF-M3-08 require special PCB layout considerations?
VTVS40GSMF-M3-08 uses the SMF (DO-219AB) package with recommended SOD-123W footprint. To maintain low-inductance paths, place it as close as possible to the protected connector or IC pin, use short, wide traces to ground, and avoid vias in the clamping path. The 309 pF junction capacitance makes trace length especially critical for high-speed interfaces like USB 2.0 when using VTVS40GSMF-M3-08.
How does the ±2 % VBR tolerance of VTVS40GSMF-M3-08 improve system reliability?
The ±2 % VBR tolerance of VTVS40GSMF-M3-08 reduces variation in clamping onset voltage across units, enabling tighter system-level surge margin design. This allows engineers to minimize overdesign in protection networks, reduce reliance on derating factors, and achieve more predictable failure thresholds - particularly valuable in safety-critical automotive and industrial applications where VTVS40GSMF-M3-08 is deployed.
