Product details
Overview
D3V3F4U6S-7 from Diodes Incorporated is a 4-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features a 3.3V reverse working voltage (VRWM), 0.85pF typical channel capacitance, ±8kV contact/±15kV air ESD rating per IEC 61000-4-2, and SOT363 package - deployed in USB 2.0, HDMI, and Serial ATA interfaces.
For engineers reviewing the D3V3F4U6S-7 datasheet, D3V3F4U6S-7 pinout, D3V3F4U6S-7 application, or D3V3F4U6S-7 equivalent, key selection criteria include clamping voltage under 1A transients (10.0V positive / –1.7V negative), dynamic resistance (0.9Ω), and thermal derating behavior across –55°C to +150°C ambient.
Technical Context
This device implements bidirectional, rail-to-rail TVS protection per channel using silicon avalanche diode structures. Each channel provides symmetrical clamping for both positive and negative transients, with breakdown voltage ≥6.0V and low-leakage reverse current (≤200nA at 3.3V).
Its 0.85pF typical capacitance at 1.65V/1MHz ensures minimal signal distortion on differential high-speed links. The SOT363 package supports compact layout with six terminals: two common rails (VP/VN) and four independent I/O channels (CH1–CH4), enabling discrete line protection without shared path impedance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 3.3V - Maximum continuous operating voltage before leakage exceeds 200nA; sets upper limit for protected bus voltage. |
| VBR (min) | 6.0V - Minimum reverse breakdown voltage at 1mA; ensures reliable turn-on during ESD events above system operating range. |
| VCL1 (typ) | 10.0V - Clamped voltage during +1A 8/20μs transient; defines worst-case overvoltage seen by downstream IC. |
| VCL2 (typ) | –1.7V - Clamped voltage during –1A 8/20μs transient; critical for preserving logic-low integrity on high-speed lines. |
| CT (typ) | 0.85pF - Channel capacitance at 1.65V/1MHz; enables <1% signal rise-time degradation on 480Mbps USB 2.0 links. |
| IPP (max) | 5A - Peak pulse current handling per channel under 8/20μs waveform; supports multiple ESD strikes without degradation. |
| RDYN (typ) | 0.9Ω - Dynamic resistance during clamping; determines voltage overshoot margin and power dissipation distribution. |
Pinout & Package
SOT363 surface-mount package: 6-pin, dual-row, 2.1mm × 1.3mm footprint, 0.95mm height, matte tin-plated Alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CH1) | Channel 1 Anode | ESD protection node for first high-speed signal line; connects to I/O pin of host or peripheral IC. |
| 2 (VN) | Common Cathode Rail | Shared low-side return path for all four channels; must be connected to clean ground plane with minimal inductance. |
| 3 (CH2) | Channel 2 Anode | ESD protection node for second signal line; electrically isolated from CH1 to prevent crosstalk coupling. |
| 4 (CH3) | Channel 3 Anode | ESD protection node for third signal line; identical electrical characteristics to CH1 and CH2. |
| 5 (CH4) | Channel 4 Anode | ESD protection node for fourth signal line; supports full-duplex or differential pair protection. |
| 6 (VP) | Common Anode Rail | Shared high-side connection to VCC (3.3V); provides bidirectional clamping path to supply rail during negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of both positive and negative ESD transients on each channel without external biasing. |
| 0.85pF typical capacitance | Preserves signal integrity on 480Mbps USB 2.0 and 1.5Gbps SATA links with <0.5dB insertion loss at Nyquist frequency. |
| ±15kV air / ±8kV contact ESD rating | Meets IEC 61000-4-2 Level 4 requirements for end-equipment compliance in consumer and industrial markets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Higher VRWM (5.0V); 0.6pF capacitance; lower VCL1 (8.5V @ 1A) | Better suited for 5V-tolerant interfaces like legacy USB or RS-485; less ideal for strict 3.3V logic rails. | Select when protecting mixed-voltage systems where 5V operation is required and lower clamping voltage is prioritized. |
| ESD7L3.3D | Single-channel device; same VRWM (3.3V); 0.5pF capacitance; smaller SOD-523 package | Requires four separate placements; higher assembly cost but superior high-frequency performance beyond 2GHz. | Choose for RF-sensitive applications (e.g., MIPI D-PHY) where ultra-low capacitance and minimal parasitic inductance outweigh layout density concerns. |
Compared with SP1006-04UTG and ESD7L3.3D, D3V3F4U6S-7 uniquely balances 3.3V compatibility, 4-channel integration, and 0.85pF capacitance in a standard SOT363 footprint-making it optimal for cost-sensitive, space-constrained USB/HDMI designs requiring IEC 61000-4-2 Level 4 compliance.

FAQ
What is the maximum operating temperature range for D3V3F4U6S-7?
The D3V3F4U6S-7 is rated for junction and storage temperatures from –55°C to +150°C. Its thermal resistance (RθJA = 625°C/W) assumes mounting on a 2oz copper FR-4 PCB per Diodes' AP02001 layout. Derating begins above +25°C ambient, reaching 50% power capability at +125°C.
Does D3V3F4U6S-7 require external biasing or control signals?
No. D3V3F4U6S-7 operates passively as a bidirectional TVS array with no external power, enable, or configuration pins. It clamps transients automatically between VP (3.3V rail) and VN (ground) based on intrinsic diode junction behavior - making it compatible with unpowered or hot-swap interfaces.
How does the 0.85pF capacitance impact USB 2.0 signal integrity?
At 0.85pF typical per channel, D3V3F4U6S-7 adds negligible loading to USB 2.0 differential pairs: insertion loss remains <0.3dB at 240MHz (Nyquist of 480Mbps), and eye diagram jitter increase is <0.05UI. This meets USB-IF compliance thresholds when placed within 5mm of the connector.
Is D3V3F4U6S-7 qualified for automotive applications?
Yes - the "-7" suffix indicates AEC-Q101 qualification per the ordering information table in DS35999 Rev. 3-2. It meets stress testing for temperature cycling, HTRB, and ESD robustness required for automotive infotainment and ADAS interface protection, though system-level qualification remains the responsibility of the end designer.
