Product details
Overview
PTVS6V3D1UCL from Nexperia is a unidirectional transient voltage suppressor diode in DFN1006-2 (SOD882P-1) package, designed to protect single-line interfaces against IEC 61000-4-5 surges and IEC 61000-4-2 ESD events. It features 6.3 V reverse standoff voltage, 56 A rated 8/20 µs surge current, 9.3 V typical clamping voltage at 56 A, 145 pF capacitance at 1 MHz, and operates from –40 °C to 125 °C ambient. Used in USB data lines and low-voltage power rails.
For engineers reviewing the PTVS6V3D1UCL datasheet, PTVS6V3D1UCL pinout, PTVS6V3D1UCL application, or PTVS6V3D1UCL equivalent, key selection criteria include unidirectional clamping behavior, ultra-low 9.3 V clamping at 56 A, 1 µA max reverse leakage at VRWM, 30 kV ESD rating (contact/air), and compatibility with high-density portable PCB layouts due to its 1.02 mm × 0.62 mm footprint.
Technical Context
This TVS diode operates as a unidirectional clamp: it remains high-impedance below 6.3 V VRWM, breaks down at ≥6.4 V (VBR, 1 mA test), and clamps transients to ≤9.3 V (typ.) during 56 A 8/20 µs pulses. Its 145 pF junction capacitance supports signal integrity on low-speed data lines like USB 2.0 or I²C.
The device uses silicon avalanche structure optimized for fast response (<1 ns), handles repetitive surges up to 150 °C junction temperature, and meets IEC 61000-4-5 Level 4 (4 kV line-to-ground) and IEC 61000-4-2 Level 4 (±30 kV contact/air) without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.3 V - Maximum continuous reverse voltage before significant leakage; defines safe operating window for protected line. |
| IPP (rated) | 56 A - Peak 8/20 µs surge current the device reliably clamps without failure per IEC 61000-4-5. |
| VCL (typ.) | 9.3 V at 56 A - Clamped voltage seen by downstream circuitry during worst-case surge; limits stress on IC inputs. |
| Cd | 145 pF at 1 MHz - Junction capacitance at 0 V bias; low enough for <480 Mbps USB 2.0 signal integrity. |
| ESD Rating | ±30 kV - Contact and air discharge per IEC 61000-4-2 Level 4; eliminates need for external ESD staging. |
| Package | DFN1006-2 (SOD882P-1) - 1.02 mm × 0.62 mm × 0.45 mm body, 0.65 mm pitch; enables ultra-compact layout in space-constrained designs. |
Pinout & Package
PTVS6V3D1UCL is housed in a leadless DFN1006-2 (SOD882P-1) surface-mount package with two terminals and a cathode band marking on the top surface. The package measures 1.02 mm × 0.62 mm × 0.45 mm with 0.65 mm terminal pitch and is compatible with standard reflow soldering profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or lower-potential rail; defines unidirectional conduction path from anode to cathode during overvoltage. |
| 2 (A) | Anode | Connected to line under protection; conducts surge current to ground when transient exceeds VBR, limiting voltage across protected node. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects positive-only or negative-only signal lines without bidirectional leakage; simplifies grounding in single-rail systems. |
| Ultra-low clamping voltage | 9.3 V typical at 56 A ensures downstream 5 V or 3.3 V logic ICs remain within absolute maximum ratings during surge events. |
| High ESD robustness | ±30 kV contact/air discharge rating eliminates need for secondary ESD components in handheld device front-end circuits. |
| Low capacitance | 145 pF enables use on USB 2.0, UART, and I²C buses without signal rise-time degradation or bit errors. |
Applications
| USB 2.0 Data Line Protection | 5 V Power Rail Clamp |
|---|---|
Use Scenario: Protecting D+ and D– lines of USB 2.0 ports in smartphones and tablets against cable-induced surges and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed between each data line and ground to clamp transients while preserving signal fidelity. Use Value: 145 pF capacitance avoids USB 2.0 eye diagram distortion; 9.3 V clamping prevents damage to USB transceivers rated for 5.5 V absolute max. | Use Scenario: Safeguarding 5 V input rails of PMICs or microcontrollers in battery-powered IoT sensors exposed to hot-plug or load-dump events. IC Role / Device Role / Timing Role: Standoff diode connected anode-to-rail, cathode-to-ground to shunt overvoltage spikes before they reach sensitive regulators. Use Value: 56 A surge rating handles 4 kV IEC 61000-4-5 line-to-ground surges; 6.3 V VRWM allows margin above nominal 5 V supply. |
| Industrial Serial Interface | Automotive Body Control Module Input |
Use Scenario: Shielding RS-232 or RS-485 transceiver pins in factory automation controllers from induced lightning surges on long cables. IC Role / Device Role / Timing Role: Point-of-entry protection on TX/RX lines referenced to local ground, leveraging unidirectional behavior for asymmetric signal swings. Use Value: 125 °C max ambient rating supports operation inside enclosures near motors or power supplies; low leakage (<1 µA) avoids DC loading on bias networks. | Use Scenario: Protecting LIN bus or switch inputs in automotive BCMs where cost-sensitive non-automotive-qualified parts are permitted for non-safety functions. IC Role / Device Role / Timing Role: Anode-to-LIN line, cathode-to-chassis ground configuration to clamp negative transients common in 12 V vehicle electrical systems. Use Value: 30 kV ESD rating withstands assembly-line handling; DFN1006-2 footprint saves board area versus SO-8 or SOT-23 alternatives. |

FAQ
What is the polarity configuration of PTVS6V3D1UCL?
PTVS6V3D1UCL is a unidirectional TVS diode: Pin 1 (K) is cathode and Pin 2 (A) is anode. It conducts only when the anode voltage exceeds the cathode voltage by ≥6.4 V (VBR), making it suitable for protecting lines with defined polarity such as 5 V rails or USB D+.
Can PTVS6V3D1UCL be used on bidirectional signal lines like I²C?
Yes, but only if the I²C line operates with a fixed reference (e.g., pulled up to 3.3 V). Since PTVS6V3D1UCL clamps only positive transients relative to ground, it protects against overshoot but not undershoot. For full bidirectional protection, a dual-diode array or bidirectional TVS is required.
How does its 9.3 V clamping voltage impact 3.3 V logic circuits?
When placed on a 3.3 V line with proper grounding, the 9.3 V clamping voltage is safe because the protected IC sees only the clamped voltage *during the transient*, not continuously. As long as the downstream IC's absolute maximum rating exceeds 9.3 V (e.g., many 3.3 V MCUs specify 6 V or higher), additional series impedance may be needed to limit peak current.
Is PTVS6V3D1UCL automotive-qualified?
No. Per Nexperia's legal disclaimers, PTVS6V3D1UCL is not qualified to AEC-Q200 or automotive standards. It is intended for industrial, computing, and consumer applications. For automotive body electronics or infotainment, Nexperia's automotive-grade PTVSxVxxD1UCL-A series should be selected instead.
