Product details
Overview
SMF6V5A-HE3_A08 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 6.5 V stand-off voltage, 7.22–8.0 V reverse breakdown at 10 mA, 20 µA max reverse leakage at VRWM, 17.9 A peak pulse current (10/1000 µs), and 11.2 V max clamping voltage at IPPM - enabling robust IEC 61000-4-2 ±30 kV contact/air discharge protection in USB 2.0, HDMI, and industrial sensor interfaces.
For engineers reviewing the SMF6V5A-HE3_A08 datasheet, SMF6V5A-HE3_A08 pinout, SMF6V5A-HE3_A08 application, or SMF6V5A-HE3_A08 equivalent, this device is selected for high-reliability ESD hardening of 5–6.5 V rail-sensitive signal paths where sub-1000 pF capacitance, AEC-Q101 qualification, and SOD-123W-compatible footprint are required.
Technical Context
This unidirectional TVS diode operates as a clamping device in reverse-biased configuration, triggering when transient voltage exceeds its breakdown threshold to divert surge current away from protected ICs. Its low incremental surge resistance and fast response time (<1 ns) ensure minimal overshoot during ESD events.
Designed for integration into compact PCB layouts, it supports wave and reflow soldering per J-STD-020 MSL level 1, with peak temperature tolerance up to 260 °C and thermal resistance RthJA = 180 K/W on standard 3 mm × 3 mm Cu pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 6.5 V - maximum continuous operating voltage before clamping begins; ensures compatibility with 5 V and 6 V logic rails without leakage-induced power loss. |
| Breakdown Voltage (VBR) | 7.22–8.0 V at 10 mA - tight tolerance window enables precise overvoltage threshold control for sensitive interface ICs. |
| Clamping Voltage (VC) | 11.2 V at 17.9 A (10/1000 µs) - limits transient voltage seen by downstream components to safe levels during surge events. |

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 | Higher clamping voltage (10.3 V), larger SMA package (4.5 × 2.7 mm), 600 pF capacitance | Better suited for lower-speed power-line protection; less ideal for USB/HDMI due to higher CD and slower response | Select SMAJ6.0A only if board space permits larger footprint and signal bandwidth is <100 Mbps. |
| TPD2E001DRYR | 2-channel array, 15 pF typical capacitance, 5.5 V stand-off, integrated 10 Ω series resistors | Optimized for ultra-high-speed digital interfaces (USB 3.0, MIPI); not unidirectional standalone solution | Choose TPD2E001DRYR when protecting dual high-speed lines with strict <20 pF budget and integrated termination is acceptable. |
Compared with SMAJ6.0A and TPD2E001DRYR, SMF6V5A-HE3_A08 delivers optimal balance of low capacitance (938 pF), precise 6.5 V stand-off, and compact DO-219AB packaging - making it preferred for cost-sensitive, space-constrained 5 V interface protection where single-line discrete clamping is required.

FAQ
What is the maximum clamping voltage of SMF6V5A-HE3_A08 at its rated peak pulse current?
The SMF6V5A-HE3_A08 has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current of 17.9 A using the 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 12 V-tolerant interface ICs. The SMF6V5A-HE3_A08 maintains this clamping performance across its full operating temperature range.
Is SMF6V5A-HE3_A08 qualified to AEC-Q101 standards?
Yes, SMF6V5A-HE3_A08 is AEC-Q101 qualified and rated for H3B-class human body model (HBM) ESD immunity exceeding 8 kV. This qualification confirms its suitability for automotive applications including infotainment, ADAS sensors, and body electronics where long-term reliability under thermal cycling, mechanical shock, and humidity exposure is mandatory. The SMF6V5A-HE3_A08 achieves this while retaining full compatibility with industrial and consumer-grade reflow profiles.
What is the reverse leakage current specification for SMF6V5A-HE3_A08 at its stand-off voltage?
At its 6.5 V stand-off voltage (VRWM), the SMF6V5A-HE3_A08 exhibits a maximum reverse leakage current (IR) of 20 µA at 25 °C. This low leakage ensures minimal power loss and signal distortion in always-on or battery-powered applications such as portable instrumentation and IoT sensor nodes. The SMF6V5A-HE3_A08 maintains this leakage performance across its full -65 °C to +175 °C operating temperature range.
Can SMF6V5A-HE3_A08 be used in USB 2.0 data line protection?
Yes, SMF6V5A-HE3_A08 is suitable for USB 2.0 D+ and D− line protection due to its 938 pF capacitance at 0 V and 1 MHz, which preserves signal integrity at 480 Mbps data rates without excessive rise-time degradation. Its 6.5 V stand-off aligns with USB 2.0 VDD tolerances, and ±30 kV IEC 61000-4-2 rating covers real-world hot-plug ESD threats. The SMF6V5A-HE3_A08 is commonly deployed in USB host controllers, hubs, and peripheral ports.
What package type does SMF6V5A-HE3_A08 use, and is it compatible with standard SOD-123 footprints?
SMF6V5A-HE3_A08 uses the DO-219AB package (also branded as SOD-123W), measuring 3.9 × 1.9 × 1.08 mm. Vishay explicitly states compatibility with SOD-123F and SOD-123FL outlines, and the footprint recommendation matches industry-standard SOD-123 land patterns - enabling direct use in existing designs without PCB revision. The SMF6V5A-HE3_A08's cathode-bar marking and tape orientation follow JEDEC-compliant carrier tape specifications for automated placement.
