Product details
Overview
D5V0S1US2SLP from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD and surge protection on signal lines in portable electronics. It features a 5.1V minimum breakdown voltage, 90A peak pulse current (8/20µs), 290pF typical junction capacitance, and operates within –55°C to +150°C. It is deployed in USB, audio, and data lines of smartphones and digital cameras.
For engineers reviewing the D5V0S1US2SLP datasheet, D5V0S1US2SLP pinout, D5V0S1US2SLP application, or D5V0S1US2SLP equivalent, key selection criteria include clamping voltage at 30–90A, low-profile X1-DFN1006-2 packaging, IEC 61000-4-2 ±30kV contact/air ESD rating, and 5.0V reverse working voltage for 3.3V/5V interface protection.
Technical Context
This unidirectional TVS diode functions as a shunt protector between a signal line and ground, triggering conduction when reverse voltage exceeds 5.1V. Its low 290pF capacitance minimizes signal distortion on high-speed lines such as USB 2.0 and audio interfaces.
The device uses silicon avalanche technology to clamp transients up to 90A (8/20µs waveform) with a maximum clamping voltage of 7.3V at full rated current. Thermal resistance is 500°C/W (junction-to-ambient), requiring minimal PCB copper area per Diodes' recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.1V min - ensures reliable turn-on before damage to downstream 3.3V/5V ICs |
| Reverse Working Voltage (VRWM) | 5.0V - matches standard 5V logic and USB VBUS tolerance margins |
| Peak Pulse Current (IPP) | 90A (8/20µs) - handles severe lightning-induced surges per IEC 61000-4-5 |
| Junction Capacitance (CT) | 290pF @ 0V, 1MHz - low enough for <480Mbps USB 2.0 without signal integrity loss |
| ESD Rating | ±30kV air & contact (IEC 61000-4-2) - exceeds industrial and consumer immunity requirements |
| Clamping Voltage (VCL) | 7.3V @ 90A - limits stress on protected ICs during worst-case surge events |
| Package | X1-DFN1006-2 - 1.02mm × 0.62mm footprint, 0.50mm max height for ultra-thin mobile designs |
Pinout & Package
Package: X1-DFN1006-2 (Type SA-2), 2-terminal, bottom-exposed thermal pad not electrically connected. Pin 1 is cathode (marked side), Pin 2 is anode - configured for unidirectional protection from signal line to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Protected Signal Input | Connected to I/O line (e.g., USB D+, audio MIC+); conducts to ground when overvoltage occurs |
| Pin 2 (Anode) | Ground Reference | Direct connection to system ground plane; establishes reference for clamping action |
Key Features

| IEC 61000-4-2 compliance | ±30kV contact/air - eliminates need for external ESD test fixtures during system validation |
| Surge robustness | 657W peak pulse power (8/20µs) - withstands multiple surge events without degradation |
| Green construction | Halogen- and antimony-free, RoHS 3 compliant - meets global environmental compliance mandates without derating |
Applications
| USB 2.0 Data Lines | Smartphone Audio Interfaces |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against ESD during cable insertion and handling. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between each data line and ground, operating below 5.0V standby and clamping above 5.1V. Use Value: Prevents latch-up or gate oxide damage in USB transceivers while maintaining <480Mbps signal integrity via 290pF capacitance. | Use Scenario: Shielding microphone bias and headset detection lines in compact handsets from user-contact ESD. IC Role / Device Role / Timing Role: Single-channel TVS tied between MIC_BIAS and GND, leveraging low leakage (<2µA) to avoid DC offset errors. Use Value: Ensures audio codec reliability under ±30kV IEC 61000-4-2 contact discharge without affecting bias voltage accuracy. |
| Portable Digital Camera I/O | Industrial Handheld Scanner Ports |
Use Scenario: Safeguarding SD card interface signals (CMD, CLK, DAT) in battery-powered cameras exposed to field ESD. IC Role / Device Role / Timing Role: One D5V0S1US2SLP per signal line, mounted adjacent to connector, with cathode to signal and anode to ground. Use Value: Maintains signal edge rates for 25MHz SD clock by limiting capacitance to 290pF and clamping transients to ≤7.3V. | Use Scenario: Protecting RS-232 or TTL-level serial debug ports on ruggedized handheld scanners used in warehouses. IC Role / Device Role / Timing Role: Unidirectional TVS on TX/RX lines referenced to local ground, selected for 90A surge margin beyond IEC 61000-4-5 Level 3. Use Value: Enables field-deployed reliability with no performance penalty-no series impedance or timing skew added to UART signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5×2.7mm), 600W PPP, 5.0V VRWM, 100A IPP, 400pF CT | Larger footprint; higher capacitance limits use to lower-speed interfaces | Select for cost-sensitive industrial boards where space is not constrained and USB/audio speed is not required. |
| SP1003-050 | SOD-323 package (1.7×1.25mm), 5.0V VRWM, 30A IPP, 120pF CT, ±30kV ESD | Lower surge rating; optimized for ESD-only, not lightning-level transients | Choose when protecting low-energy sensor lines where 90A surge capability is unnecessary and sub-150pF capacitance is critical. |
Compared with SMAJ5.0A and SP1003-050, D5V0S1US2SLP uniquely balances ultra-small size (1.02×0.62mm), 90A surge capability, and 290pF capacitance-making it optimal for space-constrained, high-speed portable interfaces requiring both ESD and IEC 61000-4-5 compliance.

FAQ
What is the polarity configuration of D5V0S1US2SLP?
D5V0S1US2SLP is a unidirectional TVS diode with cathode (Pin 1) connected to the protected signal line and anode (Pin 2) tied to ground. This configuration allows it to clamp only negative transients relative to ground while remaining non-conductive during normal positive-swing signal operation up to 5.0V.
Can D5V0S1US2SLP be used on bidirectional data lines like USB D+/D−?
Yes - its unidirectional architecture is appropriate for differential data lines referenced to ground, such as USB 2.0. One device protects each line independently (D+ to GND, D− to GND). Its 290pF capacitance and low clamping voltage preserve signal integrity without requiring series resistors or layout compromises.
Does this TVS require a thermal pad or special PCB layout?
No thermal pad is required - the X1-DFN1006-2 package has no exposed thermal terminal. However, Diodes specifies a defined pad layout (1.10mm × 0.70mm) on 2oz FR-4 to achieve the rated 500°C/W thermal resistance and 250mW steady-state power dissipation. Deviating from this layout reduces surge endurance.
Is D5V0S1US2SLP qualified for automotive applications?
As supplied, D5V0S1US2SLP is not AEC-Q200 qualified. Diodes offers automotive-grade variants (e.g., D5V0S1US2SLPQ) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. For automotive use, contact Diodes or Aetrix for the qualified version and qualification report.
