Product details
Overview
SMF6V0A-HM3_A08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for low-capacitance transient voltage suppression on high-speed data lines. It features a 6 V stand-off voltage (VRWM), 10.3 V maximum clamping voltage at 19.4 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 1063 pF typical capacitance at 1 MHz - optimized for USB 2.0, HDMI, and industrial sensor interface protection.
For engineers reviewing the SMF6V0A-HM3_A08 datasheet, SMF6V0A-HM3_A08 pinout, SMF6V0A-HM3_A08 application, or SMF6V0A-HM3_A08 equivalent, this device delivers verified AEC-Q101 qualification, low incremental surge resistance for precise clamping, and compatibility with SOD-123W footprint layouts - critical for automotive infotainment and industrial I/O port hardening.
Technical Context
This diode operates as a single-channel unidirectional TVS, leveraging silicon avalanche junction technology to clamp transients above its reverse breakdown voltage (6.67–7.4 V). Its low 1063 pF capacitance and fast response time enable use on 480 Mbps USB 2.0 differential pairs without signal integrity degradation.
The device meets IEC 61000-4-2 (±30 kV contact/air), IEC 61000-4-5 (1000 W, 8/20 μs), and AEC-Q101 Class H3B (>8 kV HBM) standards. Thermal resistance is 180 K/W when mounted on 3 mm × 3 mm Cu pads, supporting reliable operation up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |

|---|---|
Use Scenario: Protecting USB 2.0 data lines (D+/D−) in automotive head units against hot-plug ESD and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed directly at connector, clamping transients before they reach USB transceiver IC. Use Value: 10.3 V clamping voltage ensures <6.5 V stress on 5 V-tolerant PHY inputs; 1063 pF capacitance maintains <1 ns rise-time margin. |
Use Scenario: Safeguarding HDMI Display Data Channel (DDC) lines (SCL/SDA) in digital signage controllers from user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance ESD suppressor on 5 V open-drain I²C bus, preserving clock/data timing integrity. Use Value: ±30 kV contact discharge immunity prevents latch-up in HDMI source/sink EEPROMs; 6 V VRWM avoids false triggering during 3.3–5 V bus operation. |
| Industrial Sensor I/O Protection | Automotive LIN Bus Node |
Use Scenario: Shielding analog/digital sensor outputs (e.g., pressure, temperature) in PLC modules from field-induced surges and ESD. IC Role / Device Role / Timing Role: Standoff-clamp TVS on 0–10 V or 4–20 mA signal paths, referenced to chassis ground. Use Value: 175 °C max junction temperature enables direct mounting near heat-generating enclosures; 180 K/W RthJA allows passive thermal management. |
Use Scenario: Adding ESD resilience to LIN transceiver pins in door module ECUs where wiring harness exposure increases risk. IC Role / Device Role / Timing Role: Unidirectional suppressor on LIN bus line (single-wire), grounded at node PCB to limit voltage overshoot. Use Value: AEC-Q101 qualification confirms reliability under automotive thermal cycling; 10.3 V VC prevents LIN physical layer damage during ±30 kV discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/57T | Higher 11.3 V clamping voltage at same IPPM; SMA package (larger, 4.5 mm × 2.7 mm). | Less suitable for space-constrained USB 2.0 layouts; better for higher-power 24 V industrial lines. | Select SMAJ6.0A-E3/57T only if board area permits larger footprint and 11.3 V clamping is acceptable for protected IC. |
| TPD2E001DRYR | 2-channel, 15 pF per line, 6.5 V VRWM; integrated dual-diode array in SOT-553. | Designed for ultra-low-capacitance applications (e.g., USB 3.0); not AEC-Q101 qualified. | Choose TPD2E001DRYR for multi-line, high-speed interfaces where sub-20 pF is mandatory; avoid for automotive under-hood use. |
Compared with SMAJ6.0A-E3/57T and TPD2E001DRYR, SMF6V0A-HM3_A08 uniquely balances AEC-Q101 compliance, 1063 pF capacitance for USB 2.0, and DO-219AB compactness - making it optimal for cost-sensitive, thermally demanding automotive and industrial edge nodes.

FAQ
What is the clamping voltage of SMF6V0A-HM3_A08 at its rated peak pulse current?
The SMF6V0A-HM3_A08 has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 19.4 A using the 10/1000 μs waveform. This value is specified in the Electrical Characteristics table of Vishay's document 85881 and ensures safe voltage limiting for 5–6 V logic interfaces. The SMF6V0A-HM3_A08 achieves this clamping performance while maintaining low incremental surge resistance.
Is SMF6V0A-HM3_A08 qualified for automotive applications?
Yes, SMF6V0A-HM3_A08 is AEC-Q101 qualified per Vishay's documentation, meeting Class H3B human body model requirements (>8 kV) and supporting operation from −65 °C to +175 °C. This qualification validates its suitability for automotive infotainment, body electronics, and powertrain-related non-safety-critical subsystems. The SMF6V0A-HM3_A08 carries the "H" suffix in its ordering code to denote AEC-Q101 compliance.
What package does SMF6V0A-HM3_A08 use, and is it compatible with standard SOD-123W footprints?
SMF6V0A-HM3_A08 uses the DO-219AB package (also branded as SMF), with dimensions of 3.9 mm × 1.9 mm × 1.08 mm. Vishay explicitly states compatibility with SOD-123W, SOD-123F, and SOD-123FL outlines. Its land pattern matches industry-standard SOD-123W reflow soldering profiles, enabling drop-in replacement in existing layouts without PCB redesign. The SMF6V0A-HM3_A08 cathode is marked by a band on the device body.
How does the capacitance of SMF6V0A-HM3_A08 affect high-speed signal integrity?
With a typical capacitance of 1063 pF at 0 V and 1 MHz, the SMF6V0A-HM3_A08 is optimized for full-speed USB 2.0 (480 Mbps) and other moderate-bandwidth interfaces where sub-nanosecond rise times must be preserved. While higher than ultra-low-capacitance arrays, this value avoids measurable jitter or attenuation on properly terminated 90 Ω differential pairs. The SMF6V0A-HM3_A08 capacitance is measured under standardized conditions and remains stable across its operating voltage range.
What is the peak pulse power rating of SMF6V0A-HM3_A08 for different surge waveforms?
The SMF6V0A-HM3_A08 delivers 200 W peak pulse power with the 10/1000 μs waveform (per IEC 61000-4-5 Annex C) and 1000 W with the 8/20 μs waveform (per IEC 61000-4-5 main clause). These ratings reflect its ability to absorb transient energy without failure during lightning-induced surges or switching transients. The SMF6V0A-HM3_A08 maintains these ratings across its full operating temperature range, validated per Vishay's absolute maximum ratings table.
