Product details
Overview
VESD16C1-02VHG3-08 from Vishay Semiconductors is a unidirectional ESD protection diode in SOD-523 package, rated for 16 V reverse standoff voltage, 30 kV IEC 61000-4-2 contact/air discharge immunity, and 3.6 A peak pulse current (8/20 μs), deployed on high-speed data lines such as USB 2.0 or HDMI interfaces.
For engineers reviewing the VESD16C1-02VHG3-08 datasheet, VESD16C1-02VHG3-08 pinout, VESD16C1-02VHG3-08 application, or VESD16C1-02VHG3-08 equivalent, key selection criteria include clamping voltage (25.3–28 V at 3.6 A), low 21–33 pF capacitance at 0 V bias, dynamic resistance (0.53 Ω), and AEC-Q101 qualification status per ordering code suffix "H".
Technical Context
This device implements a single-line, unidirectional TVS structure optimized for low-capacitance transient suppression in signal integrity–sensitive applications. Its SOD-523 footprint enables placement directly at I/O connectors with minimal parasitic inductance.
The junction operates across –55 °C to +150 °C, supports ≤0.7 mm profile height, and features Sn (e3) lead plating compatible with automated optical inspection (AOI) and standard reflow soldering up to 260 °C peak temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF16A (ON Semiconductor) | Higher 33 V clamping (at 3.5 A), 100 pF capacitance, SMA package (4.5 × 2.7 mm) | Not suitable for high-speed data lines due to excessive capacitance; better for power rail or low-frequency I/O | Select only if board space permits larger package and signal bandwidth < 10 MHz |
| TPD2E001DRYR (Texas Instruments) | 2-channel bidirectional array, 12 pF per line, 12 V VRWM, X2SON package (1.0 × 0.8 mm) | Designed for dual-line protection (e.g., USB D+/D−); lower VRWM limits use to sub-12 V systems | Prefer for space-constrained dual-line layouts where 12 V standoff suffices and bidirectional behavior is acceptable |
Compared with SMF16A and TPD2E001DRYR, VESD16C1-02VHG3-08 uniquely balances 16 V standoff, 21–33 pF, and SOD-523 size for single-line high-speed interfaces requiring AEC-Q101 validation - neither alternative matches this combination of voltage rating, capacitance, footprint, and automotive qualification.

This range is validated per AEC-Q101 stress testing and applies to the full SOD-523 package variant bearing the "H" qualification suffix.
Does VESD16C1-02VHG3-08 meet automotive qualification standards?
Yes, VESD16C1-02VHG3-08 carries AEC-Q101 qualification, confirmed by the "H" in its ordering code. It has passed stress tests including HTOL, temperature cycling, and ESD robustness per AEC-Q101 Rev D, making it suitable for automotive infotainment, ADAS camera links, and body electronics.
What is the reverse clamping voltage of VESD16C1-02VHG3-08 under IEC 61000-4-5 surge conditions?
VESD16C1-02VHG3-08 delivers a reverse clamping voltage of 25.3–28 V when subjected to a 3.6 A peak pulse current (8/20 μs waveform per IEC 61000-4-5). This value is measured across the diode terminals with specified test setup and defines the maximum voltage imposed on downstream circuitry during surge events.
How does the capacitance of VESD16C1-02VHG3-08 affect high-speed signal integrity?
VESD16C1-02VHG3-08 exhibits 21–33 pF capacitance at 0 V bias and 1 MHz, low enough to avoid measurable eye diagram closure on USB 2.0 (480 Mbps) or MIPI D-PHY (1.5 Gbps) signals. Its SOD-523 placement within 3 mm of the connector minimizes stub inductance, preserving signal fidelity.
Is VESD16C1-02VHG3-08 compatible with lead-free reflow processes?
Yes, VESD16C1-02VHG3-08 uses Sn (e3) lead plating and is rated for peak reflow temperatures up to 260 °C per J-STD-020, fully compliant with standard lead-free soldering profiles. Its MSL level 1 rating means it can be stored indefinitely at ≤30 °C/60% RH without baking prior to assembly.
