Product details
Overview
SMF7V0A-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 7 V stand-off voltage (VRWM), 12 V maximum clamping voltage at 16.7 A peak pulse current (10/1000 μs), 843 pF typical capacitance at 0 V, ±30 kV IEC 61000-4-2 ESD immunity, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the SMF7V0A-HE3-08 datasheet, SMF7V0A-HE3-08 pinout, SMF7V0A-HE3-08 application, or SMF7V0A-HE3-08 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, low capacitance for high-speed signal integrity, automotive-grade reliability, and compatibility with SOD-123W footprint layouts.
Technical Context
This device operates as a single-channel unidirectional TVS diode, leveraging silicon avalanche breakdown to clamp transients above its reverse standoff voltage. Its low incremental surge resistance ensures rapid voltage limiting during ESD events, while its "Low Noise" technology delivers sub-nanosecond response time.
The SMF7V0A-HE3-08 is optimized for bidirectional signal line protection where polarity is fixed - cathode tied to supply rail - and supports wave and reflow soldering per J-STD-020 MSL level 1 conditions, with peak temperature up to 260 °C.
Key Specifications

|---|---|
| Stand-off Voltage (VRWM) | 7 V - maximum continuous reverse operating voltage before clamping begins |
| Clamping Voltage (VC) | 12 V at IPPM = 16.7 A (10/1000 μs) - limits transient voltage seen by protected IC |
| Peak Pulse Power | 200 W (10/1000 μs) - sustains short-duration surges without failure |
| Capacitance (CD) | 843 pF at VR = 0 V, f = 1 MHz - suitable for USB 2.0, CAN, and industrial sensor interfaces |
| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds Level 4 system-level ESD requirements |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test conditions including HBM > 8 kV |
| Operating Temp Range | –65 °C to +175 °C - supports under-hood and industrial ambient environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A-E3/5A | Higher clamping voltage (12.4 V), larger SMA package (4.5 mm × 2.7 mm), 1000 W peak power (8/20 μs) | Better suited for higher-energy surges (e.g., lightning-induced); less suitable for space-constrained high-speed lines | Select SMAJ7.0A-E3/5A when surge energy exceeds 200 W (10/1000 μs) or when legacy SMA footprint is fixed |
| TPD2E001DRYR | Bi-directional dual-channel array, 12 pF capacitance, 5.5 V VRWM, not AEC-Q101 qualified | Optimized for ultra-high-speed interfaces (USB 3.0, HDMI); lacks automotive qualification and higher-voltage clamping headroom | Select TPD2E001DRYR only for non-automotive, low-capacitance applications requiring dual-line protection in DRY package |
Compared with SMAJ7.0A-E3/5A and TPD2E001DRYR, SMF7V0A-HE3-08 uniquely balances automotive qualification, moderate capacitance, compact DO-219AB size, and precise 7 V standoff - making it optimal for cost-sensitive, space-constrained CAN/USB 2.0 nodes requiring AEC-Q101 compliance.

FAQ
What is the clamping voltage specification for SMF7V0A-HE3-08?
The SMF7V0A-HE3-08 has a maximum reverse clamping voltage (VC) of 12 V when subjected to a 10/1000 μs peak pulse current of 16.7 A. This value is measured per IEC 61000-4-5 test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping performance is guaranteed across the full operating temperature range of –65 °C to +175 °C.
Is SMF7V0A-HE3-08 qualified for automotive use?
Yes, SMF7V0A-HE3-08 is AEC-Q101 qualified, having passed all stress tests including human body model (HBM) > 8 kV, temperature cycling, and high-temperature operating life. This qualification confirms its suitability for automotive applications such as body electronics, infotainment, and powertrain subsystems where reliability under harsh environmental conditions is mandatory.
What package type does SMF7V0A-HE3-08 use, and is it compatible with standard SMT processes?
SMF7V0A-HE3-08 uses the DO-219AB package (also referenced as SOD-123W-compatible), measuring 3.9 mm × 1.9 mm × 1.08 mm. It is fully compatible with standard wave and reflow soldering per J-STD-020 MSL level 1, supporting peak temperatures up to 260 °C. The cathode is marked by a bar on the top surface, enabling automated optical inspection and placement verification.
How does the capacitance of SMF7V0A-HE3-08 affect high-speed signal integrity?
SMF7V0A-HE3-08 exhibits 843 pF typical capacitance at 0 V and 1 MHz, which is appropriate for interfaces up to USB 2.0 (480 Mbps) and CAN FD (5 Mbps), but not recommended for USB 3.0 or PCIe. This capacitance introduces minimal loading on 5 V logic lines while maintaining effective ESD suppression; design validation is advised for edge-rate sensitive applications using IBIS or SPICE models.
What is the maximum peak pulse current rating for SMF7V0A-HE3-08?
The SMF7V0A-HE3-08 is rated for a maximum peak pulse current (IPPM) of 16.7 A under the 10/1000 μs double-exponential waveform per IEC 61000-4-5. This rating reflects its ability to safely divert transient energy without parametric shift or catastrophic failure, assuming proper PCB thermal relief and grounding. Derating applies above +25 °C ambient per the RthJA = 180 K/W thermal resistance specification.
