Product details
Overview
D6V3S1U2LP-7B 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 6.5V minimum breakdown voltage, 50A peak pulse current (8/20µs), 255pF typical junction capacitance, and ±30kV IEC 61000-4-2 ESD rating - deployed in cellular handsets to safeguard USB, audio, or camera interfaces.
For engineers reviewing the D6V3S1U2LP-7B datasheet, D6V3S1U2LP-7B pinout, D6V3S1U2LP-7B application, or D6V3S1U2LP-7B equivalent, key selection criteria include clamping voltage at 10A (8.0V), low-profile X1-DFN1006-2 package (1.1mm × 0.7mm), thermal resistance (500°C/W), and IEC 61000-4-5 compliance up to 50A surge current.
Technical Context
This TVS operates as a single-channel, unidirectional clamp between two terminals (Pin 1 anode, Pin 2 cathode), triggered when reverse voltage exceeds 6.5V. Its low 255pF capacitance minimizes signal distortion on high-speed lines like USB 2.0 or I²C, while maintaining robust ESD immunity (±30kV contact/air) and 8/20µs surge handling up to 50A.
The device uses silicon avalanche technology with NiPdAu-plated copper leadframe and green molding compound (UL 94V-0). Thermal derating begins above +25°C ambient, with full power dissipation (250mW) only at ≤+25°C and linear reduction to zero at +150°C per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.5V min - Ensures reliable triggering before damage to downstream ICs rated for 6.3V max working voltage. |
| Clamping Voltage (VCL) | 8.0V @ 10A - Limits transient voltage seen by protected IC during moderate surges, preserving logic-level integrity. |
| Peak Pulse Current (IPP) | 50A @ 8/20µs - Withstands lightning-induced surges per IEC 61000-4-5 Level 3 without failure. |
| Junction Capacitance (CT) | 255pF @ 0V, 1MHz - Compatible with USB 2.0 (480Mbps) and audio codec interfaces without signal attenuation. |
| ESD Rating | ±30kV contact/air per IEC 61000-4-2 - Meets highest handheld-device ESD immunity requirement without external shielding. |
| Package Thermal Resistance | 500°C/W - Requires minimal PCB copper area for thermal management in space-constrained layouts. |
Pinout & Package

IC Role / Device Role / Timing Role: Protection element on analog audio output paths and digital control lines. Use Value: Low 255pF capacitance prevents audible pop/click artifacts during audio playback. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | DO-214AC package (4.5mm × 3.2mm), 6.0V VRWM, 100A IPP, 500pF CT | Higher capacitance limits use to DC/low-speed lines; larger footprint incompatible with ultra-thin devices. | Select when higher surge margin is required and board space permits larger package. |
| SP1003-01UTG | SOD-323 package (1.7mm × 1.25mm), 5.0V VRWM, 30A IPP, 180pF CT | Lower VBR and reduced surge rating; optimized for 3.3V logic, not 6.3V systems. | Choose for tighter voltage margins in 3.3V I/O protection where lower clamping is critical. |
Compared with SMAJ6.0A and SP1003-01UTG, D6V3S1U2LP-7B uniquely balances 6.5V breakdown, 255pF capacitance, and 50A surge rating in a 1.1mm × 0.7mm footprint - making it optimal for space-constrained 6.3V interface protection where signal integrity and ESD robustness are co-prioritized.

FAQ
What is the polarity configuration of D6V3S1U2LP-7B?
D6V3S1U2LP-7B is a unidirectional TVS diode with Pin 1 as anode and Pin 2 as cathode. It conducts only when Pin 1 is driven positive relative to Pin 2, making it suitable for protecting DC-biased signal lines such as USB D+ or I²C SDA with defined ground reference.
Does D6V3S1U2LP-7B meet automotive qualification standards?
No - D6V3S1U2LP-7B is not AEC-Q101 qualified. Diodes Incorporated explicitly states that automotive-grade variants require separate PPAP-capable manufacturing and AEC-Q101 validation; this part is intended for commercial portable electronics per its datasheet scope and marking code "3N".
How does the 255pF capacitance affect USB 2.0 signal integrity?
At 255pF, D6V3S1U2LP-7B introduces <1% rise-time degradation on 480Mbps USB 2.0 signals when placed with proper layout (short traces, ground plane). Measured TLP curves confirm sub-8V clamping at 16A, preserving eye opening and jitter margins within USB-IF compliance limits.
Can D6V3S1U2LP-7B replace bidirectional TVS devices?
No - its unidirectional architecture lacks symmetrical clamping for AC-coupled or floating lines. Bidirectional equivalents (e.g., D6V3S1U2LP's counterpart with dual avalanche structure) would be required for HDMI or Ethernet PHY protection where voltage swings occur both above and below ground.
