Product details
Overview
SMF6V0A-HE3_A18 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for low-capacitance transient suppression on high-speed data lines. It features a 6.0 V stand-off voltage (VRWM), 10.3 V maximum clamping voltage at 19.4 A peak pulse current, 1063 pF typical capacitance at 0 V, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMF6V0A-HE3_A18 datasheet, SMF6V0A-HE3_A18 pinout, SMF6V0A-HE3_A18 application, or SMF6V0A-HE3_A18 equivalent, this device is selected for robust, low-clamp overvoltage protection in USB 2.0, HDMI, CAN FD, and automotive infotainment interfaces where fast response, low leakage (<26 µA at 6 V), and thermal stability up to +175 °C are critical.
Technical Context
This diode operates as a unidirectional avalanche clamp with a reverse breakdown voltage range of 6.67–7.4 V at 10 mA test current. Its low incremental surge resistance enables tight clamping (VC = 10.3 V @ IPPM = 19.4 A, 10/1000 µs), while its "Low Noise" technology ensures sub-nanosecond response to ESD transients.
The device is rated for 200 W peak pulse power (10/1000 µs), 1000 W (8/20 µs), and supports wave/reflow soldering per J-STD-020 MSL level 1. Its SOD-123W-compatible DO-219AB package delivers 1.08 mm height and 15 mg weight for space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 6.0 V - Maximum continuous reverse operating voltage before significant leakage; sets threshold for clamping activation in signal line protection. |
| Clamping Voltage (VC) | 10.3 V max @ 19.4 A - Peak voltage seen by protected circuit during 10/1000 µs surge; defines worst-case stress on downstream ICs. |
| Capacitance (CD) | 1063 pF @ 0 V, 1 MHz - Total junction capacitance affecting signal integrity; suitable for ≤480 Mbps USB 2.0 but not USB 3.0. |

| AEC-Q101 Qualified | Yes - Validated for automotive underhood and cabin applications including temperature cycling, humidity, and mechanical shock. |
| Package | DO-219AB (SMD, 3.9 × 1.9 × 1.08 mm) - Industry-standard footprint compatible with SOD-123W reflow profiles and automated placement. |
Pinout & Package
SMF6V0A-HE3_A18 uses a 2-terminal DO-219AB (SMD) package with cathode marked by a bar. The device has no internal pins-only an anode and cathode terminal. Mounting follows standard SOD-123W land pattern with 1.3 mm pad width and 2.9 mm center-to-center spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input/Line side | Connected to protected signal line; conducts surge current toward ground when cathode is held at reference potential. |

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 clamping voltage (10.5 V @ 20.1 A); SMA (DO-214AC) package; 1.5× larger footprint. | Less suitable for ultra-thin mobile designs; better for higher-energy surges due to 400 W rating. | Select when board space allows larger package and higher 8/20 µs surge margin is required. |
| TPD2E001DRYR | 2-channel, 12 pF dual-diode array; integrated 10 kΩ series resistors; 0.65 mm × 0.65 mm DRY package. | Optimized for ultra-high-speed interfaces (USB 3.0, MIPI); not AEC-Q101 qualified. | Select for space-constrained, high-frequency applications where low capacitance outweighs automotive qualification needs. |

FAQ
What is the maximum clamping voltage of SMF6V0A-HE3_A18 under standard surge conditions?
The SMF6V0A-HE3_A18 has a maximum clamping voltage (VC) of 10.3 V when subjected to a 10/1000 µs waveform with a peak pulse current (IPPM) of 19.4 A. This value is measured per IEC 61000-4-5 and ensures protected circuits remain within safe voltage limits during transient events. The clamping performance is guaranteed across the full operating temperature range of -65 °C to +175 °C.
Is SMF6V0A-HE3_A18 qualified for automotive applications?
Yes, SMF6V0A-HE3_A18 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, humidity, mechanical shock, and ESD for use in automotive environments. Its operating temperature range (-65 °C to +175 °C), ±30 kV ESD rating, and DO-219AB package make it suitable for under-hood and cabin applications such as infotainment, body control modules, and ADAS sensor interfaces.
What is the typical junction capacitance of SMF6V0A-HE3_A18 and how does it affect signal integrity?
The SMF6V0A-HE3_A18 exhibits a typical junction capacitance of 1063 pF at 0 V and 1 MHz. This value is appropriate for USB 2.0 high-speed (480 Mbps) and HDMI DDC (I²C) applications but exceeds recommended limits for USB 3.0 or PCIe. Designers must verify eye diagram margins and rise/fall time budgets when integrating SMF6V0A-HE3_A18 into high-frequency signal paths.
Can SMF6V0A-HE3_A18 be used for bidirectional protection?
SMF6V0A-HE3_A18 is a unidirectional device, but bidirectional protection can be achieved by connecting two units in anode-to-anode configuration. In this arrangement, one SMF6V0A-HE3_A18 clamps positive transients while the other handles negative surges-providing symmetrical ±30 kV ESD immunity on differential lines like RS-485 or CAN, with matched 10.3 V clamping in both directions.
What is the package type and soldering compatibility of SMF6V0A-HE3_A18?
SMF6V0A-HE3_A18 uses the DO-219AB surface-mount package (also known as eSMP®), which is mechanically and thermally compatible with SOD-123W, SOD-123F, and SOD-123FL footprints. It supports both wave and reflow soldering per J-STD-020, with peak temperature tolerance up to 260 °C and moisture sensitivity level (MSL) 1-enabling standard automated assembly without pre-baking.
