Product details
Overview
VTVS15GSMF-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 15.1 V stand-off voltage (VRWM), ±2 % breakdown voltage tolerance (VBR = 17.6–18.31 V at IT = 1 mA), 25 V maximum clamping voltage at 15.89 A peak pulse current (10/1000 μs), and IEC 61000-4-2 ±30 kV contact/air discharge compliance.
For engineers reviewing the VTVS15GSMF-M3-08 datasheet, VTVS15GSMF-M3-08 pinout, VTVS15GSMF-M3-08 application, or VTVS15GSMF-M3-08 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, low capacitance (684 pF at 0 V), AEC-Q101 qualification status, and compatibility with SOD-123W footprint layouts.
Technical Context
The VTVS15GSMF-M3-08 employs avalanche breakdown physics to clamp transients above its 15.1 V working threshold, delivering sub-nanosecond response time and stable clamping up to 15.89 A (10/1000 μs). Its unidirectional polarity enables protection of positive-rail-only signal paths without reverse leakage concerns beyond 0.05 μA at VRWM.
Thermal resistance is rated at 20 K/W (junction-to-lead, infinite heat sink), supporting continuous operation from –55 °C to +175 °C junction temperature. The device uses halogen-free molding compound and meets MSL level 1 (J-STD-020) for reflow compatibility up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between signal line and chassis ground to shunt transients before reaching downstream ADC or microcontroller input. Use Value: Clamps 15.89 A surges to ≤25 V while maintaining <0.05 μA leakage at 15.1 V, ensuring sensor accuracy and MCU reliability. |
Use Scenario: Safeguarding D+ and D– lines of USB 2.0 ports in infotainment head units against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional-capable layout using two unidirectional devices (one per line) referenced to common ground. Use Value: 684 pF capacitance avoids signal rise-time degradation; ±30 kV IEC 61000-4-2 rating eliminates need for secondary ESD filters. |
| Industrial CAN FD Node | DC Power Rail Clamp (12 V) |
Use Scenario: Protecting CAN FD transceivers in factory automation PLCs subjected to cable discharge events and ground bounce. IC Role / Device Role / Timing Role: Placed across CANH–CANL differential pair with ground reference to absorb common-mode transients. Use Value: 25 V clamping ensures transceiver stays within absolute max ratings (typically ±40 V); 175 °C TJ rating supports sealed enclosure operation. |
Use Scenario: Secondary overvoltage clamp on 12 V supply rail feeding safety-critical microcontrollers in railway signaling equipment. IC Role / Device Role / Timing Role: Connected anode-to-ground, cathode-to-rail to limit rail excursions during load dump or alternator regulation faults. Use Value: 400 W rating handles 100 ms load dump pulses; 15.1 V VRWM allows margin below 13.5 V nominal rail while blocking normal ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/5A | ±5 % VBR tolerance (16.7–18.5 V), 600 W PPP, SMA package (higher profile, 2.3 mm height) | Higher power but larger footprint; less precise clamping threshold | Prefer when higher surge margin is needed and board height >2.3 mm is acceptable. |
| TPSMF15A | Same SMF package, ±5 % VBR, 400 W PPP, 27 V VC at 15.2 A, 600 pF | Lower clamping voltage but wider VBR spread; no AEC-Q101 option in standard M3-08 | Choose when lower VC is critical and automotive qualification is not required. |
Compared with SMAJ15A-E3/5A and TPSMF15A, the VTVS15GSMF-M3-08 delivers tighter ±2 % breakdown control and guaranteed AEC-Q101 qualification in the same low-profile SMF outline-enabling smaller, more reliable designs for automotive and industrial edge nodes where voltage margin and qualification traceability are mandatory.

FAQ
What is the clamping voltage of the VTVS15GSMF-M3-08 under a 10/1000 μs surge?
The VTVS15GSMF-M3-08 clamps to a maximum of 25 V at 15.89 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per the absolute maximum ratings table and ensures protected ICs remain within safe operating limits during transient events. The VTVS15GSMF-M3-08 achieves this with minimal voltage overshoot due to its fast avalanche response and low dynamic impedance.
Is the VTVS15GSMF-M3-08 qualified for automotive use?
Yes, the VTVS15GSMF-M3-08 is AEC-Q101 qualified, as confirmed by Vishay's ordering code "M3-08", which denotes RoHS-compliant, lead-free, halogen-free, and automotive-grade construction. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD-making the VTVS15GSMF-M3-08 suitable for under-hood and cabin applications in passenger vehicles and commercial fleets.
What is the capacitance of the VTVS15GSMF-M3-08 and how does it affect high-speed signals?
The VTVS15GSMF-M3-08 has a typical capacitance of 684 pF at 0 V reverse bias and 1 MHz frequency. This value is low enough to avoid significant signal distortion on USB 2.0 (480 Mbps) and CAN FD (5 Mbps) lines when placed with proper layout-especially with short traces and ground plane isolation. The VTVS15GSMF-M3-08 balances ESD robustness and signal fidelity better than higher-capacitance alternatives (>1 nF) commonly used in lower-speed applications.
How does the ±2 % VBR tolerance of the VTVS15GSMF-M3-08 improve circuit design margin?
The ±2 % breakdown voltage tolerance (17.6–18.31 V) of the VTVS15GSMF-M3-08 reduces uncertainty in clamping onset compared to ±5 % variants, allowing designers to set tighter voltage margins between VRWM (15.1 V) and downstream IC absolute maximum ratings. This precision minimizes overdesign risk and enables higher system-level reliability in space- and cost-constrained applications such as automotive radar modules. The VTVS15GSMF-M3-08 thus supports more aggressive voltage rail optimization without sacrificing surge safety.
Can the VTVS15GSMF-M3-08 be used in bidirectional protection configurations?
No-the VTVS15GSMF-M3-08 is a unidirectional TVS diode and must be used with anode grounded for positive-rail protection. For true bidirectional protection (e.g., AC lines or differential buses), two VTVS15GSMF-M3-08 devices can be back-to-back (anode-to-anode) or a dedicated bidirectional part like VTVS15BGS-M3-08 should be selected. Using a single VTVS15GSMF-M3-08 in reverse-biased orientation risks permanent damage during negative transients.
