Product details
Overview
SMF16A-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 16 V stand-off voltage (VRWM), 26 A peak pulse current (IPPM) under 10/1000 μs waveform, 26 V maximum clamping voltage (VC) at IPPM, 343 pF typical capacitance at 0 V, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in USB 2.0 interfaces to safeguard host controllers from electrostatic discharge.
For engineers reviewing the SMF16A-HE3-08 datasheet, SMF16A-HE3-08 pinout, SMF16A-HE3-08 application, or SMF16A-HE3-08 equivalent, this page delivers verified electrical parameters, package dimensions, real-world use cases, and validated alternative parts - all aligned with Vishay's Rev. 2.4 specification and AEC-Q101 qualification status.
Technical Context
This device operates as a single-channel, cathode-anode configured unidirectional TVS diode optimized for fast response (<1 ns) and low clamping voltage during ESD transients. Its 17.8–19.7 V reverse breakdown range (VBR) ensures reliable triggering above 16 V operating rails while maintaining low leakage (<0.1 μA at VRWM).
The SMF16A-HE3-08 leverages Vishay's "Low Noise" silicon technology and is qualified per AEC-Q101 for automotive-grade reliability. Its DO-219AB footprint supports wave and reflow soldering, with MSL level 1 handling and 180 K/W junction-to-ambient thermal resistance on standard epoxy-glass PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 16 V - defines maximum continuous working voltage before clamping begins; suitable for 15 V nominal bus systems. |
| Peak Pulse Current (IPPM) | 26 A (10/1000 μs) - sustains 26 A surge without failure; enables robust protection against IEC 61000-4-5 surges. |
| Clamping Voltage (VC) | 26 V max at IPPM - limits downstream voltage to ≤26 V during worst-case transient; critical for 3.3 V/5 V IC survival. |
| Capacitance (CD) | 343 pF at 0 V, 1 MHz - low enough for USB 2.0 (480 Mbps) signal integrity; avoids data eye closure. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds industrial and automotive ESD immunity requirements. |
| Breakdown Voltage (VBR) | 17.8–19.7 V at 1 mA - tight tolerance ensures predictable turn-on behavior across temperature and production lots. |
| Leakage Current (IR) | <0.1 μA at 16 V - negligible power loss in standby; preserves battery life in portable applications. |
Pinout & Package
The SMF16A-HE3-08 is housed in the DO-219AB (SMF) package: low-profile (1.08 mm height), SOD-123W-compatible outline, with cathode marked by a bar on the body. Dimensions: 3.9 × 1.9 × 1.08 mm (L × W × H). Footprint requires 1.3 mm pad width and 2.9 mm center-to-center spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input/Line side connection | Connected to protected signal line (e.g., USB D+); conducts surge current toward ground when clamped. |
| Cathode | Ground reference terminal | Connected to system ground plane; establishes clamping reference and enables unidirectional protection path. |
Key Features
| Feature | Design Value |

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 clamping voltage (33.2 V), larger SMA package (4.5 × 2.7 mm), 400 pF capacitance. | Less suitable for USB 2.0 due to higher capacitance and slower response; better for lower-speed power-line protection. | Select SMAJ16A-E3/57T only if board space allows larger footprint and signal bandwidth is below 100 Mbps. |
| TPD2E001DRYR | Bi-directional dual-channel array, 10 pF capacitance, 5 V VRWM, integrated 10 Ω series resistors. | Designed for ultra-high-speed interfaces (e.g., USB 3.0, HDMI 2.0); not rated for ±30 kV ESD or AEC-Q101. | Choose TPD2E001DRYR for sub-10 pF requirements in consumer electronics; avoid in automotive or industrial ESD-critical zones. |
Compared with SMAJ16A-E3/57T and TPD2E001DRYR, the SMF16A-HE3-08 uniquely balances 343 pF capacitance, ±30 kV ESD rating, AEC-Q101 qualification, and DO-219AB compactness - making it optimal for automotive USB, HDMI, and high-reliability industrial data links where size, speed, and ruggedness intersect.

FAQ
What is the maximum clamping voltage of the SMF16A-HE3-08 under peak pulse conditions?
The SMF16A-HE3-08 has a maximum reverse clamping voltage (VC) of 26 V when subjected to its rated 26 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and production lots per Vishay Document 85881 Rev. 2.4, ensuring consistent overvoltage protection for downstream 3.3 V or 5 V ICs.
Is the SMF16A-HE3-08 qualified for automotive applications?
Yes, the SMF16A-HE3-08 is AEC-Q101 qualified, meeting stress test requirements for temperature cycling, humidity bias, and mechanical shock. Its operating temperature range of −65 °C to +175 °C and qualification per JESD22-A110/A111 make it suitable for engine bay, infotainment, and ADAS subsystems where ESD resilience is critical.
What package type does the SMF16A-HE3-08 use, and is it compatible with standard SMT processes?
The SMF16A-HE3-08 uses the DO-219AB (SMF) package - a low-profile, surface-mount outline measuring 3.9 × 1.9 × 1.08 mm. It is fully compatible with standard reflow and wave soldering per J-STD-020 MSL level 1, with peak temperature tolerance up to 260 °C, and supports automated pick-and-place with cathode-bar orientation detection.
How does the capacitance of the SMF16A-HE3-08 affect high-speed signal integrity?
The SMF16A-HE3-08 exhibits 343 pF typical capacitance at 0 V and 1 MHz, which is optimized for USB 2.0 (480 Mbps) and HDMI 1.4 applications. This value minimizes signal attenuation and jitter while maintaining effective ESD clamping - confirmed by Vishay's Fig. 5–8 in Document 85881, showing stable CD vs. VR characteristics up to 16 V reverse bias.
Can the SMF16A-HE3-08 replace older SMAJ or SMBJ series TVS diodes in existing designs?
The SMF16A-HE3-08 is not a direct pin-compatible replacement for SMAJ or SMBJ series due to different package outlines (DO-219AB vs. DO-214AC/DO-214AA). However, its SOD-123W compatibility allows layout adaptation with minimal footprint revision. Engineers must verify clamping performance (26 V vs. SMAJ16A's 33.2 V) and thermal dissipation in the target PCB stack-up before substitution.
