Product details
Overview
SMF6V0A-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 V stand-off voltage (VRWM), 10.3 V maximum clamping voltage at 19.4 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 200 W peak pulse power (10/1000 μs). It is widely used in USB 2.0, HDMI, and industrial sensor interfaces requiring robust electrostatic discharge protection.
For engineers reviewing the SMF6V0A-HE3-08 datasheet, SMF6V0A-HE3-08 pinout, SMF6V0A-HE3-08 application, or SMF6V0A-HE3-08 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SOD-123W-compatible packaging details, and real-world use cases - all aligned with Vishay's Rev. 2.4 specification (Document #85881, Jul 2023).
Technical Context
This device operates as a single-channel, unidirectional TVS diode optimized for fast response (<1 ns) and low clamping voltage to protect sensitive downstream ICs. Its junction capacitance of 1063 pF at 0 V enables compatibility with moderate-speed digital interfaces without signal integrity degradation.
The SMF6V0A-HE3-08 uses silicon avalanche technology with "Low Noise" design for minimal parasitic inductance and stable clamping under repetitive ESD events. It meets AEC-Q101 stress requirements including H3B-class human body model (>8 kV) and supports wave/reflow soldering per J-STD-020 MSL level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 6 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system operating margin. |
| Clamping Voltage (VC) | 10.3 V at IPPM = 19.4 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; critical for IC survival. |
| Peak Pulse Power (PPP) | 200 W (10/1000 μs) - Sustains short-duration transients without failure; defines energy-handling capability. |

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 (10.5 V @ 21.1 A); SMA package (larger footprint, higher inductance) | Less suitable for high-speed data lines due to ~15% higher capacitance and slower response | Prefer SMF6V0A-HE3-08 where board space and signal integrity are constrained. |
| TPD2E001DRYR | Lower capacitance (11 pF), dual-channel, integrated ESD array; requires external bias for some configurations | Designed for ultra-high-speed interfaces (USB 3.0, DisplayPort); not rated for 200 W pulse power | Select SMF6V0A-HE3-08 when high-energy surge immunity (200 W) and AEC-Q101 qualification are mandatory. |
Compared with SMAJ6.0A and TPD2E001DRYR, the SMF6V0A-HE3-08 uniquely balances high pulse power handling (200 W), automotive qualification, and compact DO-219AB packaging - making it optimal for space-constrained, high-reliability industrial and automotive data-line protection where both ESD robustness and signal fidelity matter.

FAQ
What is the clamping voltage of SMF6V0A-HE3-08 at its rated peak pulse current?
The SMF6V0A-HE3-08 has a maximum clamping voltage (VC) of 10.3 V at 19.4 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per Vishay's datasheet Rev. 2.4 (Document #85881) and reflects the actual voltage imposed on protected circuitry during worst-case surge events - critical for ensuring downstream ICs remain within safe operating limits. The SMF6V0A-HE3-08 achieves this with low incremental surge resistance and fast avalanche response.
Is SMF6V0A-HE3-08 qualified for automotive applications?
Yes, SMF6V0A-HE3-08 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling (TCT), and highly accelerated stress test (HAST). It supports operating temperatures from -65 °C to +175 °C and is rated for human body model (HBM) >8 kV (Class H3B), making it suitable for automotive body electronics, infotainment interfaces, and BCM modules. The SMF6V0A-HE3-08 meets these requirements per Vishay's official qualification report referenced in Document #85881.
What package type does SMF6V0A-HE3-08 use, and is it compatible with standard SMT processes?
SMF6V0A-HE3-08 uses the DO-219AB (SMF) package - a low-profile, surface-mount outline measuring 3.9 mm × 1.9 mm × 1.08 mm. It is fully compatible with wave and reflow soldering per J-STD-020 MSL level 1 (peak temperature ≤260 °C), with no pre-bake required. Its footprint aligns with SOD-123W land patterns, enabling layout reuse. The SMF6V0A-HE3-08's cathode is marked by a bar on the top surface, supporting automated optical inspection and placement verification.
How does the junction capacitance of SMF6V0A-HE3-08 affect its suitability for high-speed data lines?
The SMF6V0A-HE3-08 exhibits 1063 pF typical junction capacitance at 0 V and 1 MHz, which is appropriate for USB 2.0 (480 Mbps) and RS-485 interfaces but too high for USB 3.x (≥5 Gbps) or HDMI 2.0+ (≥6 Gbps). This capacitance introduces measurable signal attenuation and rise-time degradation above ~100 MHz. Engineers must verify eye diagram integrity in their specific layout; the SMF6V0A-HE3-08 is intentionally optimized for robustness over bandwidth, prioritizing clamping performance and energy handling over ultra-low capacitance.
Can SMF6V0A-HE3-08 replace SMF5V0A in an existing design?
SMF6V0A-HE3-08 can replace SMF5V0A only if the system's signal line DC bias allows a 6 V stand-off voltage (VRWM) instead of 5 V - e.g., when protecting a 3.3 V rail with sufficient noise margin. The SMF6V0A-HE3-08 offers higher breakdown (6.67–7.4 V vs. 6.4–7.1 V) and slightly lower clamping (10.3 V vs. 9.2 V at respective IPPM), but its 26 μA max reverse leakage at VRWM is higher than SMF5V0A's 5 μA. Layout and thermal design remain identical due to shared DO-219AB packaging. Verify system-level ESD margin before substitution.
