Product details
Overview
VTVS15ASMF-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 15.1 V maximum stand-off voltage (VRWM), 17.1–18.8 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤25 V at 15.47 A peak pulse current (10/1000 μs), making it suitable for protecting USB, HDMI, and automotive sensor interfaces.
For engineers reviewing the VTVS15ASMF-M3-08 datasheet, VTVS15ASMF-M3-08 pinout, VTVS15ASMF-M3-08 application, or VTVS15ASMF-M3-08 equivalent, key selection criteria include its ±5 % VBR tolerance, 684 pF capacitance at 0 V, IEC 61000-4-2 ±30 kV contact/air discharge rating, and AEC-Q101 qualification readiness - critical for automotive infotainment and industrial I/O port hardening.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, optimized for fast response (<1 ns) and low clamping ratio (VC/VBR ≈ 1.4). Its thermal resistance (RthJL = 20 K/W) and 175 °C max junction temperature support high-reliability operation in compact PCB layouts with limited heat sinking.
The SMF package enables wave and reflow soldering compatibility while maintaining low-profile height (1.08 mm max) and halogen-free molding compound (UL 94 V-0 rated). Its single-channel protection path and 0.05 μA max reverse leakage at VRWM ensure minimal standby power impact on sensitive signal lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform; sustains transient surges without failure) |
| Stand-off Voltage (VRWM) | 15.1 V (maximum continuous reverse voltage before significant leakage) |
| Breakdown Voltage (VBR) | 17.1–18.8 V at IT = 1 mA (tight ±5 % tolerance ensures predictable turn-on threshold) |

Applications
| Automotive Sensor Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) from load dump and ESD in vehicle cabins. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between sensor output and microcontroller ADC input. Use Value: Limits transient voltage to ≤25 V while maintaining 684 pF capacitance that avoids signal integrity loss at DC–1 MHz bandwidth. |
Use Scenario: Safeguarding USB 2.0 D+/D− lines against ESD in portable docking stations and automotive head units. IC Role / Device Role / Timing Role: Standoff-rated TVS with 15.1 V VRWM prevents false triggering during 3.3 V logic swings while clamping ESD spikes. Use Value: Enables direct integration into USB connector PCB layout without series impedance or RC filters due to low clamping voltage and fast response. |
| HDMI Hot-Plug Detection Line | Industrial CAN FD Transceiver I/O |
Use Scenario: Securing HDMI HPD (hot-plug detect) line against insertion/removal ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS referenced to 3.3 V supply rail, placed adjacent to HDMI connector. Use Value: 684 pF capacitance avoids HPD signal rise-time degradation, while ±30 kV ESD rating exceeds IEC 61000-4-2 Level 4 requirements. |
Use Scenario: Protecting CAN FD transceiver RX/TX pins from ESD and short-to-battery transients in factory automation controllers. IC Role / Device Role / Timing Role: Standoff-rated TVS with 15.1 V VRWM aligned to 12 V CAN bus common-mode range and 25 V clamping limit. Use Value: Supports CAN FD bit rates up to 5 Mbps by limiting capacitive loading and ensuring sub-25 V clamping during 10/1000 μs surges. |
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 | Same VRWM (15 V), but higher VC = 24.4 V at 15.6 A; SMA package (larger footprint, 2.5 mm height) | Less suitable for ultra-thin designs; lower thermal resistance (RthJL = 15 K/W) allows higher average power dissipation | Select when board space permits larger package and higher surge repetition rate is required |
| 1.5SMC15A | Higher PPPM = 1500 W, but larger SMC package (7.1 × 6.2 × 2.6 mm); VRWM = 15 V, VC = 24.4 V at 43.5 A | Targeted at high-energy industrial surges (IEC 61000-4-5), not optimized for high-speed data line capacitance constraints | Choose for mains-connected equipment where 684 pF would impair signal integrity, and size is secondary |
Compared with SMAJ15A and 1.5SMC15A, VTVS15ASMF-M3-08 delivers optimal balance of low profile (1.08 mm), controlled 684 pF capacitance, and AEC-Q101-ready construction - making it preferred for space-constrained, high-data-rate, and automotive-qualified designs where footprint and signal fidelity are prioritized over raw power rating.

FAQ
What is the clamping voltage of VTVS15ASMF-M3-08 under standard 10/1000 μs surge conditions?
The VTVS15ASMF-M3-08 clamps to a maximum of 25 V at its rated peak pulse current of 15.47 A (10/1000 μs waveform), as specified in Vishay's Document Number 85891. This clamping performance ensures downstream ICs see limited overvoltage stress during transient events, and the value is measured under standardized test conditions with proper PCB thermal management.
Is VTVS15ASMF-M3-08 qualified to AEC-Q101 for automotive use?
VTVS15ASMF-M3-08 is part of the AEC-Q101-qualified eSMP® Series - the "M3" suffix denotes tape-and-reel packaging, and the base VTVS15ASMF variant is explicitly listed as AEC-Q101 qualified in Vishay's ordering matrix and qualification documentation. Full qualification evidence is available upon request for design-in validation.
What does the "-08" suffix mean in VTVS15ASMF-M3-08?
The "-08" suffix in VTVS15ASMF-M3-08 indicates 3,000 units per 7-inch reel with 8 mm tape width and a minimum order quantity of 30,000 units. This packaging code aligns with Vishay's standard SMF-device tape-and-reel configuration for automated SMT assembly, as defined in Document Number 85891.
How does the 684 pF capacitance of VTVS15ASMF-M3-08 affect high-speed data lines?
The 684 pF typical capacitance of VTVS15ASMF-M3-08 at 0 V bias is measured at 1 MHz and represents worst-case coupling; in practice, capacitance drops significantly above VRWM, enabling safe use on USB 2.0 (480 Mbps) and HDMI HPD lines. Designers should verify eye diagram integrity at target data rates, but this value is consistent with industry-standard TVS devices for sub-1 Gbps interfaces.
Can VTVS15ASMF-M3-08 replace older SMAJ15A devices in existing layouts?
VTVS15ASMF-M3-08 is not a drop-in replacement for SMAJ15A due to different package outlines: SMF (DO-219AB) vs. SMA (DO-214AC). While both share 15 V VRWM and similar electrical specs, the SMF package is 3.9 × 1.9 mm vs. SMA's 4.5 × 2.8 mm, requiring PCB footprint revision. Thermal and clamping performance differ slightly, so layout and validation updates are necessary.
