Product details
Overview
D7V0S1U2WS-7 from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 7.0 V reverse working voltage, 750 pF typical junction capacitance, ±30 kV IEC 61000-4-2 contact/air ESD rating, 90 A peak pulse current (8/20 µs), and SOD323 package - enabling robust protection in space-constrained interfaces like USB 2.0 and audio jacks.
For engineers reviewing the D7V0S1U2WS-7 datasheet, D7V0S1U2WS-7 pinout, D7V0S1U2WS-7 application, or D7V0S1U2WS-7 equivalent, key selection criteria include clamping voltage at 5–90 A, low capacitance for signal integrity, thermal derating above +25°C, and RoHS/Green compliance for consumer-grade PCB assembly.
Technical Context
This TVS operates as a single-channel, unidirectional clamp with avalanche breakdown triggered at 7.5 V (min) to limit transient overvoltage on I/O lines. Its low 750 pF capacitance ensures minimal signal distortion in 480 Mbps USB 2.0 paths, while the 10–15.5 V clamping range (at 5–90 A) maintains safe voltage margins for 3.3 V or 5 V logic receivers.
The device uses a planar silicon junction structure in a molded SOD323 package with matte tin-plated alloy 42 leads. Thermal resistance is 500 °C/W (junction-to-ambient, FR-4, 2 oz copper), requiring derating to 350 mW at +25°C and down to ~175 mW at +85°C per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 7.0 V - Maximum continuous DC voltage applied without conduction; sets upper limit for protected line voltage (e.g., USB VBUS or audio bias rails). |
| Breakdown Voltage (VBR) | 7.5–9.5 V @ 1 mA - Threshold where avalanche conduction begins; ensures reliable triggering before downstream IC damage. |
| Clamping Voltage (VCL) | 10 V @ 5 A, 12.5 V @ 50 A, 15.5 V @ 90 A - Peak voltage seen by protected circuit during surge; critical for 3.3 V/5 V I/O survival. |
| Junction Capacitance (CT) | 750 pF @ 0 V, 1 MHz - Low enough to avoid signal attenuation or timing skew in USB 2.0, HDMI DDC, or audio codec interfaces. |
| ESD Rating | ±30 kV air & contact per IEC 61000-4-2 - Meets highest consumer-grade ESD immunity requirement for handheld device ports. |
| Peak Pulse Power | 1400 W @ 8/20 µs - Sustains short-duration surges (e.g., cable discharge events) without degradation. |
Pinout & Package
Package: SOD323 - surface-mount plastic case, 0.004 g weight, UL 94V-0 rated, moisture sensitivity level 1, leadframe plated with matte tin over alloy 42.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input/Line side | Connected to protected signal line (e.g., USB D+); conducts surge current toward ground when voltage exceeds VBR. |
| Pin 2 (Cathode) | Ground reference | Connected to system ground plane; establishes reference for clamping action and provides return path for ESD current. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD protection | ±30 kV contact/air - Eliminates need for external ESD test fixtures during system-level qualification. |
| Low input capacitance | 750 pF - Preserves signal rise/fall times in 480 Mbps USB 2.0 differential pairs without added jitter. |
| Unidirectional configuration | Single anode-cathode path - Optimized for DC-biased lines (e.g., USB VBUS, audio bias), avoiding leakage on negative swings. |
| Green, lead-free construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - Complies with IPC-1752A reporting and EU EcoDesign directives. |
Applications

Use Value: Achieves full IEC 61000-4-2 compliance without degrading 50 MB/s SDHC transfer rates or increasing bit error rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A (Bourns) | Higher 1000 pF capacitance; SMA package (larger footprint, higher inductance) | Less suitable for USB 2.0; better for power rail or lower-speed interfaces | Select if board space allows larger package and capacitance budget >1000 pF |
| ESD9X7.0S (ON Semiconductor) | Same SOD-323 package; 650 pF capacitance; 8.2 V VBR min | Better signal integrity margin; tighter VBR tolerance | Prefer for new designs targeting lowest possible CT and tighter clamping consistency |
Compared with SMAJ7.0A and ESD9X7.0S, D7V0S1U2WS-7 offers balanced performance: lower capacitance than SMAJ7.0A for high-speed lines, and higher surge rating (90 A vs. 62 A for ESD9X7.0S) for ruggedized consumer ports.

FAQ
What is the maximum clamping voltage of D7V0S1U2WS-7 at 90 A?
The maximum clamping voltage is 15.5 V under 8/20 µs pulse conditions at 90 A peak current, as specified in the Electrical Characteristics table. This value ensures protected 3.3 V or 5 V logic circuits remain within absolute maximum ratings during worst-case ESD events.
Can D7V0S1U2WS-7 be used on bidirectional signal lines like USB D+/D−?
Yes - although unidirectional, it is commonly deployed on USB differential pairs with cathode tied to ground and anode on each line. Its low capacitance preserves signal integrity, and the 7.0 V VRWM accommodates USB 2.0 common-mode voltage swing without leakage.
Is D7V0S1U2WS-7 compliant with automotive AEC-Q200?
No - D7V0S1U2WS-7 is not AEC-Q200 qualified. It is rated for industrial temperature range (–55°C to +125°C) but lacks stress testing per AEC-Q200 requirements. For automotive infotainment ports, consider Diodes' AEC-Q200 qualified PUSB3FR series instead.
What is the recommended PCB pad layout for SOD323 mounting?
Diodes specifies a suggested SOD323 pad layout with X = 0.590 mm, X1 = 2.700 mm, Y = 0.450 mm, and thermal relief via patterns on the cathode pad. Full dimensions and Gerber recommendations are published at diodes.com/package-outlines.html under SOD323 outline DS38366.
