Product details
Overview
SMF9V0A-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 high-speed data lines. It features a 9.0 V stand-off voltage (VRWM), 15.4 V maximum clamping voltage at 13.5 A peak pulse current, 640 pF typical junction capacitance at 0 V, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMF9V0A-HE3-08 datasheet, SMF9V0A-HE3-08 pinout, SMF9V0A-HE3-08 application, or SMF9V0A-HE3-08 equivalent, this device is selected for robust electrostatic discharge protection in USB 2.0, HDMI, automotive infotainment interfaces, and other high-bandwidth signal paths where low clamping voltage and sub-nanosecond response are critical.
Technical Context
The SMF9V0A-HE3-08 operates as a single-channel unidirectional TVS diode with avalanche breakdown behavior, optimized for fast transient response using Vishay's "Low Noise" silicon technology. Its 10/1000 μs waveform rating of 200 W peak pulse power and 1000 W rating under 8/20 μs IEC 61000-4-5 surges enable dual-level system-level surge resilience.
It exhibits a reverse breakdown voltage range of 10.0–11.2 V at 1 mA test current, with leakage current limited to 0.1 μA at VRWM = 9.0 V. Thermal resistance is 180 K/W when mounted on a 3 mm × 3 mm Cu pad, supporting reliable operation across -65 °C to +175 °C ambient conditions.
Key Specifications

IC Role / Device Role / Timing Role: Low-leakage (0.1 μA) unidirectional clamp preserving microvolt-level signal fidelity in 24 V industrial systems. Use Value: 10–11.2 V VBR range ensures stable triggering; AEC-Q101 qualification validates long-term reliability in harsh thermal cycles. |
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 (17.1 V), larger SMA (DO-214AC) package (4.5 mm × 2.7 mm), 1000 W 8/20 μs rating only. | Less suitable for high-speed data lines due to higher capacitance (~1000 pF) and larger footprint; better for power rail protection. | Select SMAJ9.0A only when board space permits and signal bandwidth is below 100 MHz. |
| TPD2E001DRYR | Bi-directional dual-channel array, 12 pF capacitance, 12 V clamping, not AEC-Q101 qualified, 0402 package. | Optimized for ultra-high-speed digital interfaces (e.g., USB 3.0, MIPI), but lacks automotive qualification and single-line flexibility. | Choose TPD2E001DRYR for compact, high-frequency designs where AEC-Q101 is not mandated. |
Compared with SMAJ9.0A and TPD2E001DRYR, SMF9V0A-HE3-08 uniquely balances automotive qualification, low clamping, moderate capacitance, and compact DO-219AB packaging-making it optimal for cost-sensitive, high-reliability 480 Mbps data protection in automotive and industrial edge nodes.

FAQ
What is the maximum clamping voltage of the SMF9V0A-HE3-08 under standard test conditions?
The SMF9V0A-HE3-08 has a maximum reverse clamping voltage (VC) of 15.4 V when subjected to a 10/1000 μs peak pulse current of 13.5 A. This value is measured per the Electrical Characteristics table in Vishay's Document Number 85881, Rev. 2.4, and defines the upper voltage limit imposed on protected circuits during transient events. The SMF9V0A-HE3-08 maintains this clamping performance across its full operating temperature range.
Is SMF9V0A-HE3-08 suitable for protecting USB 2.0 data lines?
Yes, the SMF9V0A-HE3-08 is suitable for USB 2.0 data line protection due to its 640 pF typical junction capacitance at 0 V and 15.4 V clamping voltage, which preserves signal integrity at 480 Mbps while preventing damage from ±30 kV ESD events. Its DO-219AB package allows placement directly at the USB connector, and the 9.0 V stand-off voltage avoids interference with 3.3 V logic levels. The SMF9V0A-HE3-08 meets key design constraints for this application without requiring additional filtering.
Does SMF9V0A-HE3-08 meet automotive qualification standards?
Yes, SMF9V0A-HE3-08 is AEC-Q101 qualified, confirming its suitability for automotive applications including infotainment, body electronics, and ADAS subsystems. This qualification covers stress tests for temperature cycling, humidity, mechanical shock, and ESD robustness. The SMF9V0A-HE3-08 also complies with IEC 61000-4-2 (±30 kV contact/air) and operates from -65 °C to +175 °C, satisfying extended environmental requirements found in modern vehicle platforms.
What is the package type and dimensions of SMF9V0A-HE3-08?
The SMF9V0A-HE3-08 uses the DO-219AB package (also referenced as SMF or SOD-123W-compatible), measuring 3.9 mm in length, 1.9 mm in width, and 1.08 mm in height. It features a cathode band marking and gull-wing terminations designed for wave and reflow soldering per J-STD-020 MSL level 1. The SMF9V0A-HE3-08's compact, low-profile form factor supports high-density routing in space-constrained modules such as telematics control units and sensor hubs.
How does the leakage current of SMF9V0A-HE3-08 compare to similar TVS diodes?
The SMF9V0A-HE3-08 specifies a maximum reverse leakage current (IR) of 0.1 μA at its 9.0 V stand-off voltage (VRWM), measured at 25 °C. This low leakage supports precision analog and high-impedance sensor interfaces where parasitic current draw must be minimized. Compared to legacy SMAJ-series devices (typically 1–5 μA), the SMF9V0A-HE3-08 offers tighter leakage control-critical in battery-powered automotive modules. The SMF9V0A-HE3-08 maintains this spec across its full -65 °C to +175 °C operating range.
