Product details
Overview
SMF5V0A-HE3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for low-capacitance transient suppression on data lines. It features a 5.0 V stand-off voltage (VRWM), 6.4 V minimum breakdown voltage (VBR), 9.2 V maximum clamping voltage at 21.7 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 1120 pF typical junction capacitance at 0 V - optimized for USB 2.0, HDMI, and industrial sensor interface protection.
For engineers reviewing the SMF5V0A-HE3-08 datasheet, SMF5V0A-HE3-08 pinout, SMF5V0A-HE3-08 application, or SMF5V0A-HE3-08 equivalent, key selection criteria include clamping voltage under 21.7 A IPPM, sub-6 V VRWM for 5 V rail compatibility, SOD-123W-compatible DO-219AB footprint, AEC-Q101 qualification status, and low-noise fast-response ESD response time.
Technical Context
This device operates as a single-channel unidirectional TVS diode with avalanche breakdown behavior, engineered to clamp transients before downstream ICs exceed absolute maximum ratings. Its low incremental surge resistance enables tight voltage control during 10/1000 μs surges, while its "Low Noise" technology ensures sub-nanosecond response to ESD events.
The SMF5V0A-HE3-08 is rated for 200 W peak pulse power (10/1000 μs), 1000 W (8/20 μs), and supports continuous operation from -65 °C to +175 °C. It meets AEC-Q101 stress requirements including H3B-class human body model (>8 kV) and full IEC 61000-4-2 contact/air discharge compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 5.0 V - blocks normal 5 V rail operation while triggering only above this threshold |
| Breakdown Voltage (VBR) | 6.4–7.1 V at 10 mA - defines reliable avalanche onset range for predictable clamping |
| Clamping Voltage (VC) | 9.2 V max at 21.7 A IPPM - limits transient voltage seen by protected ICs |
| Junction Capacitance (CD) | 1120 pF at 0 V, 1 MHz - suitable for <480 Mbps interfaces like USB 2.0, not high-speed PCIe |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds automotive and industrial immunity requirements |
| Package | DO-219AB (SOD-123W-compatible) - 3.9 × 1.9 × 1.08 mm low-profile footprint for space-constrained PCBs |
| Operating Temp | -65 °C to +175 °C - qualified for under-hood automotive, industrial, and harsh-environment use |

FAQ
What is the clamping voltage of SMF5V0A-HE3-08 at its rated peak pulse current?
The SMF5V0A-HE3-08 has a maximum clamping voltage (VC) of 9.2 V at 21.7 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value ensures protected downstream ICs - such as USB transceivers or sensor amplifiers - remain within their absolute maximum voltage ratings during transient events. The clamping performance is guaranteed across the full operating temperature range of -65 °C to +175 °C.
Is SMF5V0A-HE3-08 qualified to AEC-Q101 standards?
Yes, SMF5V0A-HE3-08 is AEC-Q101 qualified and rated for H3B-class human body model ESD (>8 kV). It undergoes full stress testing per the AEC-Q101 standard, including temperature cycling, humidity bias, and high-temperature operating life. This qualification makes SMF5V0A-HE3-08 suitable for automotive applications including body electronics, infotainment, and ADAS sensor interfaces where reliability under harsh environmental conditions is required.
What package type does SMF5V0A-HE3-08 use, and is it compatible with automated assembly?
SMF5V0A-HE3-08 uses the DO-219AB (SMF) package - a 3.9 mm × 1.9 mm × 1.08 mm low-profile surface-mount case with cathode marking. It is fully compatible with standard reflow and wave soldering processes, certified to J-STD-020 MSL level 1, and supports peak temperatures up to 260 °C. Its footprint aligns with SOD-123W land patterns, enabling seamless integration into high-volume SMT production lines.
Can SMF5V0A-HE3-08 be used for bidirectional protection?
SMF5V0A-HE3-08 is a unidirectional TVS diode and is not inherently bidirectional. However, it can be configured for bidirectional protection by connecting two devices anode-to-anode in series - a standard practice for protecting AC-coupled or differential lines like RS-485. In that configuration, each SMF5V0A-HE3-08 clamps one polarity, delivering symmetrical ±9.2 V clamping with verified performance in industrial communication designs.
What is the typical junction capacitance of SMF5V0A-HE3-08, and how does it affect high-speed signal lines?
The SMF5V0A-HE3-08 has a typical junction capacitance of 1120 pF at 0 V and 1 MHz. This value is appropriate for interfaces up to 480 Mbps (e.g., USB 2.0 full-speed), but not recommended for USB 3.0 (5 Gbps), HDMI 2.0, or PCIe Gen3+ due to signal integrity impact. For those applications, lower-capacitance alternatives (<3 pF) should be selected - confirming that SMF5V0A-HE3-08 is purpose-fit for cost-sensitive, moderate-speed industrial and automotive data links.
