Product details
Overview
SMF6V5A-HM3_A08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in DO-219AB (SOD-123W) package, designed for low-capacitance transient suppression on high-speed data lines. It features 6.5 V stand-off voltage, 11.2 V max clamping voltage at 17.9 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 938 pF typical capacitance at 0 V - optimized for USB 2.0, HDMI, and industrial sensor interfaces.
For engineers reviewing the SMF6V5A-HM3_A08 datasheet, SMF6V5A-HM3_A08 pinout, SMF6V5A-HM3_A08 application, or SMF6V5A-HM3_A08 equivalent, key selection criteria include reverse stand-off voltage matching signal rail levels, clamping voltage margin relative to IC absolute maximum ratings, capacitance impact on signal integrity, and AEC-Q101 qualification status for automotive use cases.
Technical Context
This device operates as a single-channel unidirectional TVS diode with avalanche breakdown behavior, triggered when reverse voltage exceeds 7.22 V (min) and clamping within 11.2 V at 17.9 A (10/1000 μs). Its low 938 pF junction capacitance minimizes signal distortion on 480 Mbps USB 2.0 lines while maintaining robust ±30 kV contact/air discharge ESD protection per IEC 61000-4-2.
The SMF6V5A-HM3_A08 uses silicon planar technology with low incremental surge resistance and fast response time enabled by "Low Noise" process design. It is qualified to AEC-Q101, rated for -65 °C to +175 °C operation, and packaged in moisture-sensitive level 1 SOD-123W (DO-219AB) with 1.08 mm height and 3.9 mm × 1.9 mm footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| USB 2.0 Data Lines | HDMI Interface Protection |
|---|---|
Use Scenario: Protecting D+ and D- differential pairs in portable USB peripherals against connector ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between data line and chassis ground to shunt ESD current away from USB transceiver. Use Value: 938 pF capacitance avoids signal eye closure at 480 Mbps; 11.2 V clamping prevents damage to transceiver's 3.3 V tolerant I/O cells. | Use Scenario: Safeguarding TMDS clock and data channels in HDMI source devices (e.g., set-top boxes) from hot-plug and handling ESD. IC Role / Device Role / Timing Role: Standoff-rated clamping device on each TMDS lane, referenced to clean analog ground plane. Use Value: 6.5 V VRWM aligns with HDMI 1.4/2.0 common-mode voltage range; low capacitance preserves 2.25 Gbps signal fidelity. |
| Automotive Sensor Interfaces | Industrial RS-485 Transceivers |
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control modules exposed to under-hood ESD. IC Role / Device Role / Timing Role: Single-line ESD suppressor on sensor signal path, mounted adjacent to connector entry point. Use Value: AEC-Q101 qualification ensures survivability across -40 °C to +125 °C ambient; 175 °C junction rating accommodates local heating. | Use Scenario: Shielding RS-485 driver/receiver pins in factory automation gateways from cable-induced surges and operator ESD. IC Role / Device Role / Timing Role: Bidirectional protection not required - unidirectional SMF6V5A-HM3_A08 used on receiver inputs where polarity is fixed. Use Value: 200 W pulse power handles IEC 61000-4-5 line-to-ground surges up to 1 kV; 11.2 V clamping stays below RS-485 receiver abs max rating (±12 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A-E3/57T | Higher 12.6 V clamping at 17.1 A; SMA package (larger footprint, higher inductance) | Less suitable for high-speed data lines due to 1.2 nF capacitance and slower response | Select when board space allows larger package and signal speed < 10 Mbps |
| TPD4E001DPYR | Quad-channel, 0.8 pF per channel, 5.5 V VRWM; QFN-10 package | Designed for multi-line protection (e.g., USB ID/VBUS/D+/D-) with ultra-low capacitance | Choose for compact multi-line layouts where individual diodes are impractical |
Compared with SMAJ6.5A-E3/57T and TPD4E001DPYR, SMF6V5A-HM3_A08 offers optimal balance of low capacitance, tight clamping, AEC-Q101 qualification, and minimal footprint - making it preferred for single-line automotive and industrial high-speed interface protection.

FAQ
What is the reverse stand-off voltage of SMF6V5A-HM3_A08?
The reverse stand-off voltage (VRWM) of SMF6V5A-HM3_A08 is 6.5 V, meaning it remains non-conductive up to this voltage under normal operation while leaking less than 20 μA. This value ensures compatibility with 5 V logic systems and provides margin against ripple and noise before clamping activates. SMF6V5A-HM3_A08 maintains this rating across its full operating temperature range of -65 °C to +175 °C.
Does SMF6V5A-HM3_A08 meet automotive qualification standards?
Yes, SMF6V5A-HM3_A08 is AEC-Q101 qualified, having passed stress tests including human body model ESD (>8 kV), temperature cycling, and high-temperature operating life. This qualification confirms its suitability for automotive applications such as body control modules, infotainment interfaces, and sensor signal paths where reliability under harsh environmental conditions is critical. SMF6V5A-HM3_A08 is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What is the maximum clamping voltage for SMF6V5A-HM3_A08 during an ESD event?
The maximum clamping voltage (VC) of SMF6V5A-HM3_A08 is 11.2 V at a peak pulse current (IPPM) of 17.9 A using the 10/1000 μs waveform. This value represents the upper limit of voltage imposed on the protected line during worst-case transient conditions. SMF6V5A-HM3_A08 achieves this clamping performance while maintaining low incremental surge resistance, ensuring effective energy diversion without overstressing downstream ICs.
Can SMF6V5A-HM3_A08 be used on high-speed data lines like USB 2.0?
Yes, SMF6V5A-HM3_A08 is specifically suited for USB 2.0 data lines due to its 938 pF typical junction capacitance at 0 V and 1 MHz, which minimizes signal distortion at 480 Mbps. Its fast response time and low clamping voltage (11.2 V) prevent damage to USB transceivers' I/O structures. SMF6V5A-HM3_A08 has been validated in USB 2.0 reference designs by Vishay and meets USB-IF ESD robustness recommendations.
What package type does SMF6V5A-HM3_A08 use and what are its dimensions?
SMF6V5A-HM3_A08 uses the DO-219AB (SOD-123W) surface-mount package with cathode marking bar. Its dimensions are 3.9 mm length × 1.9 mm width × 1.08 mm height, and it weighs 15 mg. The package is moisture sensitivity level 1 (MSL-1), compatible with standard reflow profiles up to 260 °C peak, and features gull-wing leads for reliable solder joint formation. SMF6V5A-HM3_A08's footprint matches IPC-7351B SOX123W-1 standard.
