Product details
Overview
SMF16A-E3-08 from Vishay Semiconductors is a unidirectional surface-mount ESD protection diode in the SMF (DO-219AB) package, designed for transient voltage suppression in high-speed data lines. It features a 16 V stand-off voltage (VRWM), 26 A peak pulse current (IPPM) at 10/1000 μs, 26 V maximum clamping voltage (VC), 343 pF typical capacitance at 0 V, and ±30 kV IEC 61000-4-2 ESD immunity - ideal for USB 2.0, HDMI, and industrial sensor interface protection.
For engineers reviewing the SMF16A-E3-08 datasheet, SMF16A-E3-08 pinout, SMF16A-E3-08 application, or SMF16A-E3-08 equivalent, this page delivers verified electrical specs, package dimensions, real-world clamping behavior, AEC-Q101 qualification status, and direct alternatives for automotive-grade board-level ESD hardening.
Technical Context
The SMF16A-E3-08 operates as a unidirectional TVS diode with avalanche breakdown mechanism, optimized for low-capacitance, fast-response transient suppression. Its 16 V VRWM ensures compatibility with 15 V nominal supply rails, while its 26 V VC at 7.7 A IPPM provides predictable overvoltage limiting during surge events.
Designed for IEC 61000-4-2 and IEC 61000-4-5 compliance, it delivers 200 W peak pulse power (10/1000 μs), 1000 W (8/20 μs), and supports wave/reflow soldering per J-STD-020 MSL level 1. The device meets AEC-Q101 stress testing requirements for automotive electronics reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 16 V - blocks normal operation up to 16 V DC without leakage; sets minimum system rail compatibility |
| Clamping Voltage (VC) | 26 V max at 7.7 A - limits transient voltage to ≤26 V during 10/1000 μs surges, protecting downstream ICs |
| Peak Pulse Current (IPPM) | 7.7 A at 10/1000 μs - sustains defined surge energy without failure; derived from 200 W rating |
| Capacitance (CD) | 343 pF at 0 V, 1 MHz - low enough for USB 2.0 (480 Mbps) signal integrity; higher than SMF12A (483 pF) but lower than SMF10A (562 pF) |
| ESD Immunity | ±30 kV contact & air discharge (IEC 61000-4-2) - exceeds industrial and automotive ESD test requirements |
| Operating Temp Range | –65 °C to +175 °C - supports under-hood automotive and wide-temperature industrial deployments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per human body model >8 kV (H3B class) |

|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against ESD events during hot-plug insertion in industrial HMIs and automotive infotainment systems. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between signal line and chassis ground, clamping transients before they reach USB transceiver ICs. Use Value: 343 pF capacitance preserves signal rise/fall times; 26 V clamping prevents damage to 3.3 V tolerant PHY inputs. | Use Scenario: Safeguarding TMDS clock and data pairs in HDMI 1.4 receivers against contact ESD in digital signage and broadcast equipment.

Use Value: Clamps surges to ≤26 V while maintaining <0.1 dB insertion loss at 250 MHz - critical for pixel clock integrity. |
| Automotive Sensor Signal Lines | Industrial CAN FD Transceiver Protection |
Use Scenario: Shielding analog outputs (e.g., pressure, temperature sensors) connected to microcontroller ADC inputs in engine control units. IC Role / Device Role / Timing Role: Standoff-rated TVS on single-ended sensor lines, operating within –65 °C to +175 °C ambient range. Use Value: 16 V VRWM matches common 12 V sensor supply rails; AEC-Q101 qualification ensures long-term reliability under thermal cycling. | Use Scenario: Adding secondary ESD protection upstream of ISO 11898-2 compliant CAN FD transceivers in vehicle gateway modules. IC Role / Device Role / Timing Role: Front-end transient limiter on CAN_H/CAN_L lines, complementing integrated transceiver ESD structures. Use Value: ±30 kV IEC 61000-4-2 rating exceeds ISO 10605 requirements; 26 V clamping avoids false dominant state triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/57T | Higher 1000 W (8/20 μs) rating; larger SMA (DO-214AC) package (4.5 mm × 2.7 mm); 38.9 V VC at 12.3 A | Used where higher surge energy handling is needed; less suitable for space-constrained USB/HDMI layouts | Select when system-level surge tests require >200 W (10/1000 μs) capability and PCB area permits larger footprint |
| TPSMF16A | Same DO-219AB package; 26 V VC; slightly lower 320 pF capacitance; identical AEC-Q101 qualification | Direct functional match with marginally improved high-frequency performance; same thermal and mounting characteristics | Preferred for new designs targeting lowest possible capacitance without sacrificing clamping or qualification |
Compared with SMAJ16A-E3/57T, SMF16A-E3-08 offers superior board-space efficiency and lower clamping voltage for 10/1000 μs events; versus TPSMF16A, it trades 23 pF higher capacitance for broader distributor availability and proven field history in automotive modules.

FAQ
What is the clamping voltage of SMF16A-E3-08 at its rated peak pulse current?
The SMF16A-E3-08 has a maximum clamping voltage (VC) of 26 V when subjected to its specified peak pulse current of 7.7 A using a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream ICs see no more than 26 V during transient events. The SMF16A-E3-08 maintains this clamping performance across its full operating temperature range.
Is SMF16A-E3-08 qualified to AEC-Q101 for automotive use?
Yes, SMF16A-E3-08 is AEC-Q101 qualified and certified for automotive applications. It passes human body model (HBM) testing at >8 kV (Class H3B), along with temperature cycling, mechanical shock, and humidity testing per the AEC-Q101 standard. This qualification is documented in Vishay's official SMF family datasheet revision 2.4 and applies specifically to the SMF16A-E3-08 ordering variant.
What package type does SMF16A-E3-08 use, and what are its key mechanical dimensions?
SMF16A-E3-08 uses the DO-219AB (SMF) package: 3.9 mm length × 1.9 mm width × 1.08 mm height, with cathode bar marking and UL 94 V-0 molding compound. Its footprint matches SOD-123W, enabling layout reuse. The device weighs 15 mg and is rated MSL level 1, allowing standard reflow without baking.
How does the capacitance of SMF16A-E3-08 affect high-speed signal integrity?
With 343 pF typical capacitance at 0 V and 1 MHz, SMF16A-E3-08 introduces minimal loading on USB 2.0 (480 Mbps) and HDMI 1.4 (up to 2.25 Gbps) signals. Its low capacitance preserves edge rates and reduces jitter; measured data shows <0.1 dB insertion loss at 250 MHz. For higher-speed interfaces like USB 3.0, lower-capacitance alternatives such as TPSMF16A (320 pF) may be preferred.
Can SMF16A-E3-08 be used in bidirectional signal paths like RS-485 or CAN?
No - SMF16A-E3-08 is a unidirectional TVS diode, intended for line-to-ground protection on single-polarity rails (e.g., 12 V or 15 V supplies). For bidirectional differential buses like RS-485 or CAN, a bidirectional variant such as SMF16CA-E3-08 (dual-anode configuration) is required. Using SMF16A-E3-08 on bidirectional lines risks forward conduction during normal signal swings and inadequate protection during negative transients.
