Product details
Overview
SMF6V0A-HM3_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 V standoff 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 0 V - deployed in USB 2.0, HDMI, and industrial sensor interfaces.
For engineers reviewing the SMF6V0A-HM3_A18 datasheet, SMF6V0A-HM3_A18 pinout, SMF6V0A-HM3_A18 application, or SMF6V0A-HM3_A18 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, low capacitance for signal integrity, AEC-Q101 qualification status, and SOD-123W-compatible footprint compatibility with automated assembly.
Technical Context
This device operates as a single-channel unidirectional TVS diode optimized for electrostatic discharge protection in space-constrained, high-reliability applications. Its junction temperature range spans –65 °C to +175 °C, and it delivers 200 W peak pulse power per the 10/1000 μs waveform with 0.01 % duty cycle.
The SMF6V0A-HM3_A18 uses silicon avalanche technology with "Low Noise" fast-response design, achieving sub-nanosecond response time. It is rated for 50 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits 2.5 V forward clamping at 50 A, supporting robust overvoltage resilience in DC-biased signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 6 V - maximum continuous reverse operating voltage before conduction begins; defines safe operating margin for 5 V logic rails. |
| Breakdown Voltage (VBR) | 6.67–7.4 V at 10 mA - ensures reliable triggering above normal signal swing while avoiding false triggering. |
| Clamping Voltage (VC) | 10.3 V at 19.4 A IPPM - limits transient voltage seen by downstream ICs during ESD events, protecting 3.3 V/5 V interface receivers. |
| Capacitance (CD) | 1063 pF at 0 V, 1 MHz - low enough for USB 2.0 full-speed (12 Mbps) and industrial analog sensor lines without signal degradation. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 immunity requirements for industrial and automotive infotainment ports. |

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), larger SMA package (4.5 × 2.7 mm), 600 W peak power (8/20 μs). | Better suited for higher-energy surges (IEC 61000-4-5), but higher capacitance (1200 pF) limits USB 2.0 use. | Select when surge energy exceeds 200 W (10/1000 μs) and board space allows larger footprint. |
| TPD2E001DRYR | Two-channel bidirectional array, 15 pF capacitance, 5.5 V VRWM, not AEC-Q101 qualified. | Optimized for ultra-high-speed digital interfaces (e.g., USB 3.0, PCIe), but lacks automotive qualification and single-line flexibility. | Choose for low-capacitance multi-line protection where AEC-Q101 is not required and layout permits dual-channel placement. |
Compared with SMAJ6.0A-E3/57T and TPD2E001DRYR, the SMF6V0A-HM3_A18 offers the optimal balance of automotive qualification, compact DO-219AB size, and 1063 pF capacitance - making it preferred for space-limited, AEC-Q101–mandated USB/HDMI/sensor protection where moderate surge energy suffices.

FAQ
What is the clamping voltage of the SMF6V0A-HM3_A18 at its rated peak pulse current?
The SMF6V0A-HM3_A18 has a maximum clamping voltage (VC) of 10.3 V at 19.4 A peak pulse current (IPPM) under the 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream ICs see limited overvoltage during ESD events. The SMF6V0A-HM3_A18 maintains this clamping performance across its full operating temperature range of –65 °C to +175 °C.
Is the SMF6V0A-HM3_A18 qualified to AEC-Q101, and what does that qualification cover?
Yes, the SMF6V0A-HM3_A18 is AEC-Q101 qualified, covering stress tests including human body model (HBM) ESD >8 kV (Class H3B), temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This qualification confirms suitability for automotive applications such as infotainment, ADAS camera links, and body control modules. The SMF6V0A-HM3_A18 meets all required failure criteria per the AEC-Q101 standard.
What is the capacitance of the SMF6V0A-HM3_A18, and how does it affect high-speed signal integrity?
The SMF6V0A-HM3_A18 exhibits 1063 pF typical capacitance at 0 V and 1 MHz. This value is low enough to avoid significant signal distortion on USB 2.0 full-speed (12 Mbps) and low-speed industrial analog lines, though it is not suitable for USB 3.0 or HDMI 2.0+ where sub-100 pF is typically required. The SMF6V0A-HM3_A18's capacitance remains stable across reverse bias voltages up to VRWM, ensuring predictable performance in DC-biased interfaces.
Can the SMF6V0A-HM3_A18 be used in bidirectional signal paths like RS-485 or CAN?
No - the SMF6V0A-HM3_A18 is a unidirectional TVS diode, intended only for DC-biased or ground-referenced signal lines (e.g., USB D+, HDMI TMDS+). It cannot protect true bidirectional differential buses like RS-485 or CAN without external biasing circuitry. For those applications, a bidirectional variant such as SMF6.0CA or dedicated array devices are required. The SMF6V0A-HM3_A18 must be oriented with cathode to ground and anode to the protected line.
What is the package type and soldering compatibility of the SMF6V0A-HM3_A18?
The SMF6V0A-HM3_A18 uses the DO-219AB (SMF) package: 3.9 mm × 1.9 mm × 1.08 mm, with cathode marking and SOD-123W-compatible footprint. It supports both wave and reflow soldering per J-STD-020, with peak temperature up to 260 °C and MSL level 1 handling. The SMF6V0A-HM3_A18 is RoHS-compliant and lead-free, with tin-plated terminations and UL 94 V-0 molding compound.
