Product details
Overview
SMF9V0A-HM3_A08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for robust transient voltage suppression in high-speed data lines. It features a 9.0 V standoff voltage, 15.4 V maximum clamping voltage at 13.5 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and 200 W peak pulse power (10/1000 μs). It is widely deployed in USB 2.0, HDMI, and industrial sensor interfaces.
For engineers reviewing the SMF9V0A-HM3_A08 datasheet, SMF9V0A-HM3_A08 pinout, SMF9V0A-HM3_A08 application, or SMF9V0A-HM3_A08 equivalent, key selection criteria include reverse standoff voltage (VRWM), clamping performance under 10/1000 μs surge, junction temperature range (−65 °C to +175 °C), capacitance (640 pF at 0 V), and AEC-Q101 qualification status.
Technical Context
This device operates as a single-channel unidirectional TVS diode with avalanche breakdown behavior, optimized for low-clamping, fast-response ESD protection in space-constrained PCB layouts. Its DO-219AB package enables high thermal dissipation (RthJA = 180 K/W on 3 mm × 3 mm Cu pads) and supports wave/reflow soldering per J-STD-020 MSL level 1.
The SMF9V0A-HM3_A08 delivers precise voltage threshold control: reverse breakdown occurs between 10.0 V and 11.2 V at 1 mA test current, with leakage current limited to ≤0.1 μA at 9.0 V standoff - critical for preserving signal integrity in low-power analog and digital I/O paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 9.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 10.0–11.2 V at 1 mA - defines reliable avalanche initiation threshold for transient clamping |
| Clamping Voltage (VC) | 15.4 V at 13.5 A (10/1000 μs) - limits downstream IC voltage stress during surge events |
| Peak Pulse Power | 200 W (10/1000 μs) - sustains short-duration transients without failure in typical board-level ESD scenarios |
| Capacitance (CD) | 640 pF at 0 V, 1 MHz - impacts high-frequency signal integrity; suitable for ≤10 Mbps interfaces |
| ESD Immunity | ±30 kV contact/air discharge (IEC 61000-4-2) - exceeds industrial and automotive ESD immunity requirements |
| Operating Temp Range | −65 °C to +175 °C - supports deployment in under-hood automotive, industrial, and aerospace environments |

Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in embedded host/device ports against ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed inline between connector and USB transceiver IC to clamp transients before they reach sensitive PHY circuitry. Use Value: 640 pF capacitance avoids signal distortion at 480 Mbps; 15.4 V clamping prevents damage to 3.3 V tolerant USB PHY inputs. | Use Scenario: Safeguarding TMDS clock and data channels in consumer displays and set-top boxes exposed to user-accessible connectors. IC Role / Device Role / Timing Role: Single-channel ESD suppressor on each TMDS lane, referenced to chassis ground, to absorb contact discharges up to ±30 kV. Use Value: Low incremental surge resistance minimizes voltage overshoot during fast ESD pulses, preserving eye diagram integrity at 2.25 Gbps. |
| Automotive Sensor I/O Protection | Industrial CAN Bus Node Protection |
Use Scenario: Shielding analog outputs (e.g., 4–20 mA loop drivers) and digital I/O (e.g., LIN, PWM) of engine control sensors from under-hood ESD and load dump coupling. IC Role / Device Role / Timing Role: Standalone unidirectional TVS mounted at connector entry point to shunt transients to local ground plane before reaching ASIC or microcontroller pins. Use Value: −65 °C to +175 °C operating range matches under-hood thermal profiles; AEC-Q101 qualification confirms reliability in automotive-grade production. | Use Scenario: Adding secondary ESD hardening to CANH/CANL lines in industrial gateways where primary protection resides in the transceiver. IC Role / Device Role / Timing Role: Discrete TVS diode placed across differential pair to clamp common-mode surges while preserving CAN bus DC bias and signal symmetry. Use Value: 9.0 V VRWM allows safe operation with 5 V CAN transceivers; 200 W pulse rating handles repetitive ESD in factory-floor environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Higher clamping voltage (17.5 V), larger SMA (DO-214AC) package (4.5 mm × 2.7 mm), 600 W peak power (10/1000 μs) | Better suited for higher-energy surges but less space-efficient; higher capacitance (800 pF) limits use in >5 Mbps links | Select SMAJ9.0A only when board layout permits larger footprint and higher clamping is acceptable for downstream 5 V logic. |
| TPD2E001DRYR | Integrated dual-channel ESD array (2-line), 12 pF capacitance, 5.5 V VRWM, 12 V VC, 300 W (8/20 μs), SC-70 package | Designed for ultra-high-speed interfaces (USB 3.0, MIPI); not AEC-Q101 qualified; lower voltage rating restricts use to 3.3 V systems | Choose TPD2E001DRYR for compact, low-capacitance protection in portable electronics - not for automotive or high-voltage industrial I/O. |
Compared with SMAJ9.0A and TPD2E001DRYR, SMF9V0A-HM3_A08 offers optimal balance of compact DO-219AB packaging, AEC-Q101 qualification, 9.0 V standoff, and 640 pF capacitance - making it ideal for cost-sensitive, space-constrained, and automotive-qualified 10 Mbps–100 Mbps interface protection.

FAQ
What is the standoff voltage rating of SMF9V0A-HM3_A08?
The SMF9V0A-HM3_A08 has a maximum standoff voltage (VRWM) of 9.0 V, meaning it remains non-conductive under normal operating conditions up to this reverse voltage. This value ensures compatibility with 5 V and 3.3 V logic systems while providing margin before avalanche conduction begins at its 10.0–11.2 V breakdown range. The 9.0 V rating is confirmed in the Electrical Characteristics table of Vishay document 85881.
Is SMF9V0A-HM3_A08 qualified to AEC-Q101?
Yes, SMF9V0A-HM3_A08 is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section of Vishay's SMF5V0A to SMF58A datasheet (Rev. 2.4, 04-Jul-2023). It meets human body model (HBM) Class H3B (>8 kV) and supports automotive applications including infotainment, body control modules, and sensor nodes where reliability under temperature cycling and mechanical stress is required.
What is the clamping voltage of SMF9V0A-HM3_A08 at its rated peak pulse current?
The SMF9V0A-HM3_A08 exhibits a maximum clamping voltage (VC) of 15.4 V when subjected to its rated 13.5 A peak pulse current with a 10/1000 μs waveform. This clamping performance is measured under standardized surge conditions and ensures protected downstream ICs - such as USB transceivers or CAN controllers - remain within their absolute maximum voltage ratings during ESD events.
Does SMF9V0A-HM3_A08 have a bidirectional or unidirectional configuration?
SMF9V0A-HM3_A08 is a unidirectional TVS diode, as confirmed by its single-channel construction, cathode-bar marking, and electrical specifications (e.g., reverse breakdown only, no symmetric forward/reverse parameters). It protects against positive transients on the anode relative to cathode-ground - appropriate for DC-biased signal lines like USB D+, HDMI TMDS+, or CANH in standard configurations.
What is the package type and footprint compatibility of SMF9V0A-HM3_A08?
SMF9V0A-HM3_A08 uses the DO-219AB (SMF) package: 3.9 mm × 1.9 mm × 1.08 mm, with cathode-bar orientation and SOD-123W-compatible footprint. Its land pattern recommendation is provided in Vishay's package drawing S8-V-3915.01-001, supporting automated placement and reflow soldering per J-STD-020 MSL level 1 guidelines.
