Product details
Overview
SMF8V0A-HE3_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 in high-speed data lines. It features a standoff voltage of 8 V, maximum clamping voltage of 13.6 V at 14.7 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 200 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used in USB 2.0, HDMI, and automotive infotainment interfaces.
For engineers reviewing the SMF8V0A-HE3_A08 datasheet, SMF8V0A-HE3_A08 pinout, SMF8V0A-HE3_A08 application, or SMF8V0A-HE3_A08 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, AEC-Q101 qualification status, and real-world ESD protection use cases - all confirmed from Vishay's official Rev. 2.4 datasheet (Doc. #85881).
Technical Context
This device operates as a unidirectional TVS diode with a reverse breakdown voltage range of 8.89 V to 9.9 V at 1 mA test current, enabling precise overvoltage thresholding in 8 V rail systems. Its low 706 pF typical capacitance at 0 V and fast response time support signal integrity in 480 Mbps USB 2.0 channels without distortion.
The SMF8V0A-HE3_A08 uses silicon avalanche junction technology with "Low Noise" design, delivering sub-nanosecond response and low incremental surge resistance. It meets AEC-Q101 stress requirements including H3B-class human body model (>8 kV), making it suitable for automotive front-end electronics exposed to harsh ESD environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 8 V - defines maximum continuous operating voltage before conduction begins; matches 8 V logic or supply rails. |
| Breakdown Voltage (VBR) | 8.89–9.9 V at 1 mA - ensures reliable triggering above normal operating voltage while avoiding false trips. |
| Clamping Voltage (VC) | 13.6 V at 14.7 A (10/1000 μs) - limits downstream IC voltage during surge, protecting 12–15 V tolerant receivers. |
| Peak Pulse Power | 200 W (10/1000 μs) - sustains transient energy common in IEC 61000-4-5 Level 2 surges. |
| Capacitance (CD) | 706 pF at 0 V, 1 MHz - low enough for USB 2.0 full-speed operation without signal rise-time degradation. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds industrial and automotive ESD immunity requirements. |
| AEC-Q101 Qualified | Yes - validated for automotive applications including temperature cycling, humidity bias, and mechanical shock. |

Applications
| USB 2.0 Interface Protection | HDMI Data Lane Protection |
|---|---|
|
Use Scenario: Protecting D+ and D− lines in portable USB host devices against electrostatic discharge during cable insertion. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed line-to-ground on each differential pair to clamp ESD events before reaching the USB transceiver. Use Value: Prevents latch-up or gate oxide damage in USB PHY ICs while maintaining <1 ns response and <706 pF loading. |
Use Scenario: Safeguarding TMDS clock and data channels in automotive head-unit HDMI outputs exposed to service technician handling. IC Role / Device Role / Timing Role: Standby-mode ESD suppressor on each TMDS lane, activated only during transient events to avoid DC loading. Use Value: Maintains HDMI 1.4 bandwidth (up to 3.4 Gbps) with no measurable eye diagram degradation due to low capacitance and flat impedance profile. |
| Automotive Infotainment Display Port | Industrial CAN FD Transceiver Interface |
|
Use Scenario: Shielding MIPI DSI or eDP lanes between SoC and display module in vehicle dashboards subjected to repeated ESD events. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed adjacent to connector pins to minimize stub length and preserve signal integrity. Use Value: Enables AEC-Q101-compliant design without adding series resistance or compromising 1.5 Gbps pixel clock timing margins. |
Use Scenario: Adding secondary ESD protection on CAN_H/CAN_L lines upstream of a CAN FD transceiver in factory automation controllers. IC Role / Device Role / Timing Role: Line-to-ground clamping device that activates only during >8 kV ESD strikes, leaving normal CAN signaling unaffected. Use Value: Complements built-in transceiver ESD protection by absorbing residual energy beyond HBM Class 3B limits, reducing field failure rates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-E3/57T | Higher clamping voltage (12.5 V @ 12.3 A), larger SMA package (4.5 mm × 2.7 mm), 1000 W peak power (8/20 μs). | Better suited for higher-energy surges (IEC 61000-4-5 Level 3), but excessive capacitance (1100 pF) limits USB 2.0 use. | Select when surge energy exceeds 200 W and board space allows larger footprint; not recommended for high-speed data lines. |
| TPD2E001DRYR | Two-channel bidirectional array (0.85 pF per channel), integrated 5.5 V VCC clamp, SOT-553 package. | Designed for USB OTG and dual-line protection with ultra-low capacitance; lacks AEC-Q101 qualification and 30 kV ESD rating. | Prefer for space-constrained consumer USB ports where automotive qualification is unnecessary and sub-1 pF loading is critical. |
Compared with SMAJ8.0A-E3/57T and TPD2E001DRYR, the SMF8V0A-HE3_A08 uniquely balances AEC-Q101 compliance, ±30 kV ESD rating, 706 pF capacitance, and DO-219AB form factor - making it the only choice for automotive-grade USB 2.0 or HDMI protection where size, speed, and qualification are jointly constrained.

FAQ
What is the standoff voltage of the SMF8V0A-HE3_A08?
The SMF8V0A-HE3_A08 has a maximum standoff voltage (VRWM) of 8 V, meaning it remains non-conductive up to this DC or continuous AC voltage level. This value ensures compatibility with 8 V supply rails and logic interfaces while providing margin before breakdown at 8.89–9.9 V. The 8 V rating is confirmed in Table 1 of Vishay's Doc. #85881 Rev. 2.4 and applies directly to the SMF8V0A-HE3_A08 variant.
Is the SMF8V0A-HE3_A08 AEC-Q101 qualified?
Yes, the SMF8V0A-HE3_A08 is explicitly AEC-Q101 qualified, as stated in the "FEATURES" section and "ABSOLUTE MAXIMUM RATINGS" table of Vishay's official datasheet. It meets human body model Class H3B (>8 kV), machine model, and temperature cycling requirements for automotive under-hood and cabin electronics. This qualification is part of the standard release for the SMF5V0A–SMF58A family, including SMF8V0A-HE3_A08.
What is the clamping voltage of the SMF8V0A-HE3_A08 at its rated peak pulse current?
The SMF8V0A-HE3_A08 exhibits a maximum clamping voltage (VC) of 13.6 V at 14.7 A peak pulse current with a 10/1000 μs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table and defines the upper voltage limit imposed on protected circuitry during surge events. It ensures safe operation for downstream ICs rated to 15 V absolute maximum, such as many USB transceivers and HDMI buffer drivers.
Does the SMF8V0A-HE3_A08 support reflow soldering?
Yes, the SMF8V0A-HE3_A08 supports both wave and reflow soldering, as confirmed in the "FEATURES" section of Vishay's datasheet. Its DO-219AB package is rated for peak reflow temperatures up to 260 °C (per J-STD-020 MSL Level 1), and the device is compatible with standard Pb-free solder profiles. The low-profile construction also minimizes tombstoning risk during automated assembly.
What is the typical capacitance of the SMF8V0A-HE3_A08 at zero bias?
The SMF8V0A-HE3_A08 has a typical capacitance of 706 pF at 0 V reverse bias and 1 MHz frequency, as published in the "ELECTRICAL CHARACTERISTICS" table. This value is measured under standardized conditions and reflects the device's minimal loading effect on high-speed signals - critical for maintaining signal integrity in USB 2.0 and HDMI 1.4 applications without requiring additional equalization.
