Product details
Overview
SMF6V5A-HE3-08 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 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 ±30 kV IEC 61000-4-2 ESD protection in USB 2.0, HDMI, and industrial sensor interfaces.
For engineers reviewing the SMF6V5A-HE3-08 datasheet, SMF6V5A-HE3-08 pinout, SMF6V5A-HE3-08 application, or SMF6V5A-HE3-08 equivalent, this device delivers verified AEC-Q101 qualification, SOD-123W-compatible footprint, 938 pF typical capacitance at 0 V, and low incremental surge resistance - critical for signal integrity in automotive infotainment and industrial I/O protection designs.
Technical Context
This unidirectional TVS diode operates as a clamping device in parallel with protected signal paths, activating when transient voltages exceed its breakdown threshold. Its "Low Noise" technology ensures sub-nanosecond response time, minimizing overshoot during ESD events while maintaining low dynamic impedance under surge conditions.
The SMF6V5A-HE3-08 is optimized for single-line protection with one protection path, rated for continuous operation from –65 °C to +175 °C, and validated for wave and reflow soldering per J-STD-020 MSL level 1 (peak 260 °C). Its DO-219AB package enables high thermal dissipation (RthJA = 180 K/W on 3 mm × 3 mm Cu pads) and supports automated placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 6.5 V - maximum continuous reverse operating voltage before clamping begins; defines safe signal swing range for 5 V logic and USB 2.0 data lines. |
| Breakdown Voltage (VBR) | 7.22–8.0 V at 10 mA - tight tolerance ensures predictable turn-on across temperature and production lots. |
| Clamping Voltage (VC) | 11.2 V max at 17.9 A (10/1000 μs) - limits downstream IC stress during transients; critical for protecting 12 V-tolerant receivers. |
| Peak Pulse Power (PPP) | 200 W at 10/1000 μs - sustains short-duration surges without degradation; sufficient for IEC 61000-4-5 Level 2 (1 kV) immunity. |
| Capacitance (CD) | 938 pF at 0 V, 1 MHz - low enough for USB 2.0 (480 Mbps) and RS-485, but not suitable for PCIe or HDMI 2.0+. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds automotive and industrial ESD immunity requirements. |
| AEC-Q101 Qualified | Yes - qualified for automotive applications including infotainment, body control modules, and ADAS sensor interfaces. |
Pinout & Package
The SMF6V5A-HE3-08 uses the DO-219AB (SMF) package: low-profile (1.08 mm height), 3.9 mm × 1.9 mm footprint, cathode-bar marked, compatible with SOD-123W, SOD-123F, and SOD-123FL land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
|
Use Scenario: Protecting USB 2.0 D+ and D– lines against user-handling ESD in portable docking stations and peripheral hubs. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed directly at connector, shunting transients to ground before reaching USB transceiver.

Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines in smart TVs and AV receivers exposed to frequent cable insertion/removal. IC Role / Device Role / Timing Role: Low-capacitance TVS placed inline between SoC GPIO and HDMI connector, preserving 100 kHz I²C timing margins. Use Value: Prevents latch-up in HDMI controller ICs during ±15 kV air discharge events without adding propagation delay to CEC command signals. |
| Automotive Infotainment Displays | Industrial RS-485 Transceivers |
|
Use Scenario: Shielding LVDS or FPD-Link III video interface traces in automotive center displays from dashboard ESD coupling. IC Role / Device Role / Timing Role: Discrete ESD suppressor mounted adjacent to display connector, clamping fast-rising transients before they reach timing-critical serializer ICs. Use Value: Enables AEC-Q101-compliant design with no visual artifacts (e.g., pixel dropouts or screen flicker) after 500+ ±25 kV contact discharges. |
Use Scenario: Protecting RS-485 transceiver inputs in factory automation gateways connected to long, unshielded field wiring. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional diode (used in back-to-back configuration) suppressing common-mode surges induced by motor switching noise. Use Value: Extends mean time between failures (MTBF) of RS-485 nodes by 3× in electrically noisy environments with 2 kV EFT bursts. |
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-E3/5A | Higher VRWM (6.0 V vs. 6.5 V), higher clamping (10.5 V vs. 11.2 V), larger SMA package (4.5 mm × 2.7 mm). | Less suitable for space-constrained USB 2.0 layouts; better for lower-voltage 3.3 V systems where tighter VRWM margin is needed. | Select SMAJ6.0A-E3/5A only if board area allows SMA footprint and system operates near 3.3 V logic levels. |
| TPD2E001DRYR | Integrated dual-channel ESD array (2 lines), 10 pF capacitance, 5.5 V VRWM, not AEC-Q101 qualified. | Designed for high-speed digital interfaces (e.g., eMMC, SDIO); lacks automotive qualification and single-line flexibility. | Choose TPD2E001DRYR for compact multi-line protection in non-automotive consumer electronics with strict capacitance budgets. |
Compared with SMAJ6.0A-E3/5A and TPD2E001DRYR, the SMF6V5A-HE3-08 uniquely balances AEC-Q101 compliance, 6.5 V stand-off headroom for 5 V systems, and DO-219AB miniaturization - making it optimal for automotive USB-C accessories and industrial HMI front panels where reliability and size are co-constrained.

FAQ
What is the maximum clamping voltage of the SMF6V5A-HE3-08 at its rated peak pulse current?
The SMF6V5A-HE3-08 has a maximum clamping voltage (VC) of 11.2 V at its rated peak pulse current of 17.9 A (10/1000 μs waveform). This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMF6V5A-HE3-08 maintains this clamping performance across its full operating temperature range of –65 °C to +175 °C.
Is the SMF6V5A-HE3-08 qualified to AEC-Q101, and what does that qualification cover?
Yes, the SMF6V5A-HE3-08 is AEC-Q101 qualified, covering stress tests including high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing (uHAST), and ESD human body model (H3B, >8 kV). This qualification confirms suitability for automotive applications such as infotainment displays and body control modules. The SMF6V5A-HE3-08 meets all required test conditions per Rev. 2.4 of Vishay's 85881 datasheet.
What is the typical junction capacitance of the SMF6V5A-HE3-08, and at what bias condition is it specified?
The SMF6V5A-HE3-08 has a typical junction capacitance (CD) of 938 pF, measured at 0 V reverse bias and 1 MHz frequency. This value is confirmed in the Electrical Characteristics table of the Vishay datasheet (Document Number: 85881, Rev. 2.4). The SMF6V5A-HE3-08's capacitance decreases with increasing reverse voltage - dropping to ~200 pF at 3 V - supporting its use in moderate-speed digital interfaces.
Can the SMF6V5A-HE3-08 be used in bidirectional signal protection applications?
The SMF6V5A-HE3-08 is a unidirectional TVS diode and is not inherently bidirectional. However, it can be used in bidirectional protection schemes when paired with a second SMF6V5A-HE3-08 in series opposition (anode-to-anode or cathode-to-cathode), forming a symmetrical clamping structure. This configuration is documented in Vishay application notes for RS-485 and CAN bus protection. The SMF6V5A-HE3-08 itself supports only unidirectional clamping per its datasheet specification.
What is the package type and moisture sensitivity level (MSL) rating for the SMF6V5A-HE3-08?
The SMF6V5A-HE3-08 uses the DO-219AB (SMF) package, also referenced as eSMP® Series, with dimensions of 3.9 mm × 1.9 mm × 1.08 mm. Its moisture sensitivity level is MSL level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without baking prior to reflow. The SMF6V5A-HE3-08 is rated for peak reflow temperatures up to 260 °C.
