Product details
Overview
D5V0S1U2WS-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 5.5 V reverse working voltage, 6.2 V minimum breakdown voltage, 950 pF typical capacitance at 0 V, ±30 kV IEC 61000-4-2 contact/air ESD rating, and 70 A peak pulse current handling capability.
For engineers reviewing the D5V0S1U2WS-7 datasheet, D5V0S1U2WS-7 pinout, D5V0S1U2WS-7 application, or D5V0S1U2WS-7 equivalent, this device is selected for low-capacitance, single-channel ESD clamping in space-constrained USB, audio, and display interfaces where signal integrity and robustness against human-body-model surges are critical.
Technical Context
This TVS operates as a unidirectional clamping device with avalanche breakdown triggered at ≥6.2 V to divert ESD transients away from protected ICs. Its SOD323 package enables integration into tight-pitch layouts while maintaining thermal resistance of 500 °C/W on standard FR-4 PCBs.
The device delivers 1000 W peak pulse power (8/20 μs waveform), clamps to ≤9 V at 5 A and ≤16 V at 70 A, and exhibits <3 μA leakage at 5.5 V reverse bias-enabling compatibility with 5 V logic and low-power interface circuits without loading effects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.5 V - Maximum continuous DC voltage applied without triggering conduction; compatible with 5 V I/O rails. |
| Breakdown Voltage (Min) | 6.2 V - Avalanche onset threshold; ensures clamping activates only during overvoltage events. |
| Clamping Voltage (70 A) | 16 V - Maximum voltage seen by protected circuit during worst-case 70 A surge; limits stress on downstream ICs. |
| Capacitance (0 V, 1 MHz) | 950 pF - Low enough for USB 2.0 and audio line protection without signal distortion. |
| ESD Rating (IEC 61000-4-2) | ±30 kV (Contact/Air) - Meets highest industrial ESD immunity requirement for handheld end-equipment. |
| Peak Pulse Power | 1000 W - Sustains 8/20 μs surges up to 70 A without degradation under defined thermal conditions. |
Pinout & Package
Package: SOD323 - surface-mount plastic case, 0.004 g weight, UL 94V-0 rated, moisture sensitivity level 1, lead-free matte tin plating on Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Input terminal for protected signal line | Connected to I/O trace; conducts surge current to cathode when reverse-biased beyond VBR. |
| Pin 2 (Cathode) | Ground reference / return path | Connected to system ground plane; completes clamping path during ESD event. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD protection | ±30 kV contact and air discharge - eliminates need for external ESD test margining in final product validation. |
| Low input capacitance | 950 pF typical - preserves signal rise/fall times in high-speed interfaces like USB 2.0 and HDMI DDC lines. |
| Unidirectional clamping architecture | Single-channel, anode-to-cathode configuration - simplifies layout and avoids forward-bias leakage on bidirectional buses. |
| RoHS-compliant & halogen-free | Lead-free, <900 ppm Br/Cl, <1000 ppm Sb - satisfies global environmental compliance requirements without derating. |
Applications
| USB 2.0 Data Lines | Smartphone Audio Jacks |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 transceivers from user-handling ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed directly at connector, shunting ESD energy to ground before it reaches PHY IC. Use Value: 950 pF capacitance prevents signal integrity degradation while ±30 kV rating ensures pass-fail compliance in IEC 61000-4-2 pre-compliance testing. | Use Scenario: Shielding 3.5 mm audio jack microphone and ground lines in smartphones against repeated plug-in ESD pulses. IC Role / Device Role / Timing Role: Single-channel ESD suppressor mounted adjacent to jack contacts, operating in reverse-bias standby mode until surge occurs. Use Value: 5.5 V VRWM allows safe operation with biased mic bias rails; 16 V clamping at 70 A prevents latch-up in audio codec inputs. |
| Portable Display Interfaces | SD Card Slot Protection |
Use Scenario: Safeguarding MIPI D-PHY clock and data lanes in OLED/LCD modules from ESD induced during panel replacement or flex-cable handling. IC Role / Device Role / Timing Role: Low-capacitance TVS placed inline on each differential pair, minimizing skew between lanes. Use Value: Matched 950 pF capacitance across channels maintains timing alignment; 6.2 V VBR avoids false triggering during normal 3.3 V swing operation. | Use Scenario: Preventing ESD damage to SDIO controller pins during hot-plug insertion of memory cards in tablets and cameras. IC Role / Device Role / Timing Role: Discrete unidirectional clamp per signal line (CMD, CLK, DAT0–3), grounded at card slot shield. Use Value: 70 A IPP rating handles multiple simultaneous contact discharges; SOD323 footprint fits within narrow SD slot keep-out zones. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Higher 5.0 V VRWM, 1000 pF CT, DO-214AC package (larger than SOD323) | Used in industrial PCBs with less space constraint; higher thermal mass but lower board density | Select when board layout permits larger footprint and higher clamping voltage (12.5 V @ 50 A) is acceptable. |
| TPD2E001DRYR | 2-channel, 12 pF CT, 5.5 V VRWM, same SOD-523 footprint | Targets dual-line protection (e.g., USB D+/D−); ultra-low capacitance trades off lower surge rating (4 A IPP) | Choose for high-speed differential pairs requiring sub-15 pF loading; not suitable for 70 A surge environments. |
Compared with SMAJ5.0A and TPD2E001DRYR, D5V0S1U2WS-7 uniquely balances 950 pF capacitance, 70 A surge capability, and SOD323 size-making it optimal for single-line, high-reliability ESD protection in ultra-compact portable designs.

FAQ
What is the maximum clamping voltage of D5V0S1U2WS-7 at 50 A?
The maximum clamping voltage is 12 V at 50 A peak pulse current with an 8/20 μs waveform, as specified in the Electrical Characteristics table. This value ensures downstream ICs experience limited overvoltage stress during mid-level ESD events, supporting reliable operation in portable electronics subject to frequent handling.
Can D5V0S1U2WS-7 be used for bidirectional signal lines?
No-D5V0S1U2WS-7 is a unidirectional TVS diode and must be used only on lines referenced to ground with defined polarity. For bidirectional interfaces like USB full-speed differential pairs, two unidirectional devices or a dedicated bidirectional TVS (e.g., D5V0F1U2UP) are required to protect both positive and negative transients.
Is the SOD323 package suitable for automated optical inspection (AOI)?
Yes-the SOD323 package has standardized dimensions (1.30 × 1.70 mm body, 0.30 mm lead width) and visible top-side marking (Q12), enabling reliable AOI detection during SMT assembly. Its flat, symmetrical profile and matte tin finish further support consistent solder joint inspection and process yield control.
Does D5V0S1U2WS-7 require derating at elevated ambient temperatures?
Yes-power dissipation must be derated linearly above +25°C, with full derating to zero at +125°C, per the Figure 1 power derating curve. At +85°C ambient, maximum allowable power drops to approximately 175 mW, limiting usable surge repetition rate in thermally constrained enclosures.
