Product details
Overview
SMF5V0A-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 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 capacitance at 0 V.
For engineers reviewing the SMF5V0A-HE3_A08 datasheet, SMF5V0A-HE3_A08 pinout, SMF5V0A-HE3_A08 application, or SMF5V0A-HE3_A08 equivalent, key selection criteria include clamping voltage under 21.7 A surge, sub-1.1 mm height for space-constrained PCBs, AEC-Q101 qualification for automotive use, and compatibility with SOD-123W footprint layouts.
Technical Context
This device operates as a single-channel unidirectional TVS diode optimized for electrostatic discharge protection on I/O lines such as USB 2.0, HDMI, and Ethernet PHY interfaces. Its low 1120 pF capacitance minimizes signal integrity impact, while the 9.2 V clamping voltage ensures safe voltage limiting during 10/1000 μs transients up to 200 W peak power.
The SMF5V0A-HE3_A08 uses silicon avalanche technology with "Low Noise" fast-response design, achieving sub-nanosecond response time. It is rated for continuous operation from –65 °C to +175 °C and qualified to AEC-Q101 for automotive under-hood and infotainment applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/57T | Higher clamping voltage (11.2 V at 21.1 A); SMA package (4.5 mm × 2.7 mm); 1500 pF capacitance. | Less suitable for USB 2.0 due to higher capacitance and larger footprint; better for lower-speed industrial I/O. | Select when board space allows larger package and higher clamping is acceptable for 5 V rail protection. |
| TPD2E001DRYR | Bi-directional dual-channel array; 12 pF capacitance; integrated 5 V DC blocking; DRY package (2.0 mm × 1.25 mm). | Optimized for ultra-high-speed interfaces like USB 3.0 or MIPI; not unidirectional or AEC-Q101 qualified. | Select for compact, low-capacitance dual-line protection where automotive qualification is not required. |

FAQ
What is the clamping voltage specification for SMF5V0A-HE3_A08 under standard surge conditions?
The SMF5V0A-HE3_A08 has a maximum reverse clamping voltage (VC) of 9.2 V at 21.7 A peak pulse current with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuitry during transient events. The SMF5V0A-HE3_A08 maintains this clamping performance across its full operating temperature range.
Is SMF5V0A-HE3_A08 qualified for automotive applications?
Yes, the SMF5V0A-HE3_A08 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including infotainment, ADAS, and body electronics. It meets stringent requirements for temperature cycling, humidity resistance, and mechanical shock. The SMF5V0A-HE3_A08 is rated for continuous operation from –65 °C to +175 °C, supporting under-hood and cabin-mounted deployments.
What package type does SMF5V0A-HE3_A08 use, and is it compatible with standard SOD-123 footprints?
The SMF5V0A-HE3_A08 uses the DO-219AB (SMF) package: 3.9 mm × 1.9 mm × 1.08 mm, with cathode bar marking. It is explicitly stated as compatible with SOD-123W, SOD-123F, and SOD-123FL footprints. While not identical to standard SOD-123, the SMF5V0A-HE3_A08's land pattern recommendations align with SOD-123W layout guidelines, enabling straightforward PCB integration.
How does the capacitance of SMF5V0A-HE3_A08 affect high-speed signal integrity?
The SMF5V0A-HE3_A08 exhibits 1120 pF typical capacitance at 0 V and 1 MHz, which is appropriate for USB 2.0 (480 Mbps) and HDMI 1.4 (up to 3.4 Gbps) applications where moderate loading is acceptable. This capacitance introduces minimal rise-time degradation on properly terminated lines. For higher-speed interfaces like USB 3.0 or PCIe, lower-capacitance alternatives would be preferred-but the SMF5V0A-HE3_A08 remains optimal for cost-sensitive, robust ESD protection in mid-speed designs.
Does SMF5V0A-HE3_A08 support both contact and air discharge ESD testing per IEC 61000-4-2?
Yes, the SMF5V0A-HE3_A08 is rated for ±30 kV contact discharge and ±30 kV air discharge per IEC 61000-4-2, verified with 10 pulses per polarity. This dual-rating confirms its effectiveness against common human-body ESD events encountered during assembly, field service, and end-user interaction. The SMF5V0A-HE3_A08 achieves this performance using Vishay's "Low Noise" avalanche structure with sub-nanosecond response.
