Product details
Overview
VTVS17ASMF-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. It features a 16.9 V maximum stand-off voltage (VRWM), 19.0–21.0 V reverse breakdown voltage (VBR) at 1 mA, 28 V clamping voltage (VC) at 13.79 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity-used in automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS17ASMF-M3-08 datasheet, VTVS17ASMF-M3-08 pinout, VTVS17ASMF-M3-08 application, or VTVS17ASMF-M3-08 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, thermal resistance (20 K/W), halogen-free SOD-123W-compatible packaging, and AEC-Q101 qualification readiness for automotive-grade designs.
Technical Context
This TVS diode operates as a unidirectional shunt protector with avalanche breakdown behavior, triggered when reverse voltage exceeds 19.0 V (min) at 1 mA test current. Its low 20 K/W junction-to-lead thermal resistance enables reliable power dissipation during 400 W peak pulses without thermal runaway in compact PCB layouts.
The device delivers fast response via "Low-Noise" technology, achieving sub-nanosecond turn-on to clamp transients before downstream IC damage. Its 606 pF capacitance at 0 V bias is optimized for signal integrity in ≤10 MHz analog/power-line applications-not suitable for high-speed data lines like USB 2.0 or HDMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform): sustains single-event surges up to 400 W without failure |
| Stand-off Voltage (VRWM) | 16.9 V max: blocks normal operation up to 16.9 V DC while remaining non-conductive |
| Breakdown Voltage (VBR) | 19.0–21.0 V at IT = 1 mA: precise avalanche threshold ensures consistent triggering across temperature |
| Clamping Voltage (VC) | 28 V at IPPM = 13.79 A: limits transient voltage to ≤28 V during worst-case surge |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2): meets highest industrial and automotive ESD robustness class |
| Junction Temp Range | −55 °C to +175 °C: supports under-hood automotive and industrial environments |
| Capacitance (CD) | 606 pF at VR = 0 V, f = 1 MHz: low enough for 12 V power rail filtering, too high for USB/MIPI |
Pinout & Package
SMF (DO-219AB) package: low-profile surface-mount outline compatible with SOD-123W footprint; cathode marked by bar on top surface; dimensions 3.9 × 1.9 × 1.08 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground; completes shunt path during overvoltage events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17A | Higher 600 W rating; larger SMB (DO-214AA) package; 30.5 V VC at 19.9 A | Requires more PCB area; better for higher-energy surges but less space-efficient | Select when surge energy exceeds 400 W or board layout allows SMB footprint |
| 1.5SMC17A | Same 400 W rating; larger SMC (DO-214AB) package; 27.6 V VC at 14.5 A; MSL level 1 | Lower clamping voltage but incompatible with dense SMT layouts due to 7.11 mm length | Prefer for cost-sensitive industrial designs where size constraints are relaxed |
Compared with VTVS17ASMF-M3-08, SMBJ17A offers higher surge capacity at the expense of footprint, while 1.5SMC17A trades lower clamping for significantly larger package-making VTVS17ASMF-M3-08 optimal for space-constrained automotive and portable medical PCBs requiring precise 16.9 V standoff.

FAQ
What is the maximum clamping voltage of the VTVS17ASMF-M3-08 under peak pulse conditions?
The VTVS17ASMF-M3-08 has a maximum reverse clamping voltage (VC) of 28 V at 13.79 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value ensures downstream ICs see no more than 28 V during transient events, directly supporting design margin calculations for 3.3 V and 5 V logic rails powered from protected 12 V sources. The VTVS17ASMF-M3-08 maintains this clamping performance across its full operating temperature range.
Is the VTVS17ASMF-M3-08 qualified to AEC-Q101?
The VTVS17ASMF-M3-08 is part of Vishay's AEC-Q101-qualified eSMP® family, with qualification documentation available upon request. While the base part number does not embed the "-H" automotive suffix, the underlying die and assembly process meet AEC-Q101 stress test requirements-including temperature cycling, HTRB, and ESD testing. Customers requiring certified automotive release should specify VTVS17ASMF-HM3-08. The VTVS17ASMF-M3-08 itself is rated for −55 °C to +175 °C operation, matching AEC-Q101 thermal scope.
What is the package type and footprint compatibility of the VTVS17ASMF-M3-08?
The VTVS17ASMF-M3-08 uses the SMF (DO-219AB) package: a low-profile SMD outline measuring 3.9 × 1.9 × 1.08 mm, with cathode marked by a bar. It is mechanically and solder-reflow compatible with SOD-123W footprints and functionally interchangeable with SOD-123F/FL variants. The VTVS17ASMF-M3-08 requires no adapter or layout change when migrating from legacy SOD-123 designs, supporting drop-in replacement in existing reflow processes.
How does the ±5 % VBR tolerance of the VTVS17ASMF-M3-08 impact circuit protection design?
The ±5 % breakdown voltage tolerance (denoted by the "A" suffix in VTVS17ASMF-M3-08) guarantees VBR between 19.0 V and 21.0 V at 1 mA, enabling tighter margining versus the 16.9 V VRWM. This allows designers to confidently set system overvoltage thresholds just above 21.0 V without risk of false triggering, improving noise immunity while maintaining robust surge response. The VTVS17ASMF-M3-08's tight tolerance eliminates need for derating VRWM below 16.9 V in production validation.
Can the VTVS17ASMF-M3-08 be used on high-speed data lines such as USB or CAN?
No-the VTVS17ASMF-M3-08 has a typical capacitance of 606 pF at 0 V, which would severely distort signal integrity on high-speed buses like USB 2.0 (≤10 pF required), CAN FD (≤200 pF), or Ethernet. It is engineered for DC power rail and low-frequency analog signal protection only. For data line protection, Vishay offers specialized low-capacitance TVS arrays (e.g., VTVSxxGSMF series with matched capacitance). The VTVS17ASMF-M3-08 must be applied exclusively to non-high-speed nodes.
