Product details
Overview
PTVS6V3Z1UCL 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 (40 A, 8/20 µs) and IEC 61000-4-2 ESD events (±30 kV). It features 6.3 V reverse standoff voltage, 9.3 V typical clamping at 40 A, and 100 pF capacitance at 1 MHz - ideal for high-speed USB or low-voltage I²C line protection in portable electronics.
For engineers reviewing the PTVS6V3Z1UCL datasheet, PTVS6V3Z1UCL pinout, PTVS6V3Z1UCL application, or PTVS6V3Z1UCL equivalent, key selection criteria include unidirectional clamping behavior, ultra-low 0.45 mm profile for space-constrained PCBs, thermal robustness up to 150 °C junction temperature, and compatibility with reflow soldering per SOD882P-1 footprint.
Technical Context
This TVS diode operates as a unidirectional clamp, conducting only when anode-to-cathode voltage exceeds breakdown (6.4–9 V), enabling protection of positive-polarity signal lines without interfering with normal operation below VRWM = 6.3 V. Its 100 pF capacitance ensures minimal signal distortion on data lines up to ~100 MHz.
The device meets IEC 61000-4-5 Level 4 surge immunity (40 A, 8/20 µs) and IEC 61000-4-2 contact/air discharge (±30 kV), with clamping performance validated under both TLP (100 ns) and standard 8/20 µs waveforms. Junction temperature is rated to 150 °C, supporting use in thermally demanding power management subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.3 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe working range for protected line |
| VBR (min) | 6.4 V at 1 mA - Ensures reliable turn-on before damaging overvoltage occurs on sensitive IC inputs |
| VCL (typ) | 9.3 V at 40 A - Limits peak transient voltage seen by downstream circuitry during worst-case surge |
| IPPM | 40 A (8/20 µs) - Sustains industrial-grade surge immunity per IEC 61000-4-5 without degradation |
| Cd | 100 pF at 1 MHz, 0 V - Low enough to avoid signal integrity issues on USB 2.0 or I²C bus lines |
| ESD Rating | ±30 kV (IEC 61000-4-2) - Protects against human-body-model and air-gap discharges in handheld devices |
| Tj max | 150 °C - Enables placement near hot components like DC-DC converters without derating |
Pinout & Package
DFN1006-2 (SOD882P-1) is a leadless, ultra-small surface-mount package measuring 1.02 mm × 0.62 mm × 0.45 mm with 0.65 mm pitch. Its low profile supports high-density routing and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line; conducts surge current toward ground when forward-biased during positive transients |
| 2 (A) | Anode | Connected to system ground; completes conduction path during overvoltage events on the protected line |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects only positive-going transients on grounded-return lines, avoiding false triggering on negative signal swings |
| Ultra-low clamping voltage | 9.3 V typical at 40 A ensures downstream 5 V or 3.3 V logic remains within absolute maximum ratings during surge |
| Low capacitance | 100 pF enables integration on high-speed digital interfaces without measurable rise-time degradation |
| Miniature DFN package | 0.45 mm height and 0.62 mm width allow placement directly at connector or IC pin for shortest possible protection path |
| High ESD robustness | ±30 kV rating eliminates need for secondary ESD stages in consumer-grade portable designs |
Applications
| USB 2.0 Data Line Protection | I²C Bus Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones and accessories against cable-induced surges and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed between each data line and ground, clamping transients before they reach USB transceiver ICs. Use Value: Prevents latch-up or permanent damage to PHY layers while maintaining <1 ns response time and <100 pF loading. | Use Scenario: Safeguarding SDA/SCL lines in battery-powered IoT sensors exposed to handling ESD and board-level coupling noise. IC Role / Device Role / Timing Role: Standalone line protector mounted adjacent to microcontroller I/O pins, absorbing ±30 kV discharges per IEC 61000-4-2. Use Value: Eliminates need for series resistors or RC filters that would degrade 400 kHz timing margins on I²C buses. |
| Power Supply Input Protection | Portable Audio Interface Protection |
Use Scenario: Guarding 5 V or 3.3 V input rails of PMICs or LDOs in wearables against hot-plug transients and load-dump spikes. IC Role / Device Role / Timing Role: Primary surge clamp on main power rail, positioned upstream of filtering capacitors to absorb energy before it propagates. Use Value: Withstands 40 A surges while limiting clamped voltage to ≤12 V, preserving input stage reliability of downstream regulators. | Use Scenario: Shielding analog audio paths (e.g., headset jack detection lines) in Bluetooth earbuds from user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance TVS on bias or sense lines connected to audio codecs, preventing pop-noise and ADC saturation. Use Value: 100 pF capacitance avoids audible artifacts; 6.3 V VRWM matches common audio bias voltages without leakage-induced offset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | DO-214AC package (4.5 mm × 2.7 mm); higher VCL = 10.5 V at 32.4 A; 10× larger footprint | Used where board space is unconstrained and higher surge margin is needed; not suitable for fine-pitch layouts | Select when mechanical robustness outweighs size constraints and PCB real estate is available |
| TPD2E001DRYR | 2-channel bidirectional array in DFN1006-3; 15 pF per channel; lower 5.5 V VRWM; rated for 4 A IPPM | Optimized for dual-line ESD-only protection (e.g., HDMI DDC), not high-energy surge | Choose for multi-line, low-capacitance ESD-only needs - not a drop-in replacement for 40 A surge duty |
Compared with SMAJ6.0A and TPD2E001DRYR, PTVS6V3Z1UCL uniquely balances ultra-miniaturization (DFN1006-2), 40 A surge capability, and 100 pF capacitance - making it optimal for space-limited, high-reliability single-line protection where both ESD and surge immunity are required.

FAQ
What is the polarity configuration of PTVS6V3Z1UCL?
PTVS6V3Z1UCL is a unidirectional TVS diode, meaning it protects only positive-going transients on a line referenced to ground. Pin 1 (K) connects to the protected line, and Pin 2 (A) connects to ground. It does not conduct during negative excursions, making it suitable for DC-biased signal lines like USB D+ or power rails.
Can PTVS6V3Z1UCL be used on bidirectional data lines such as RS-485?
No - PTVS6V3Z1UCL is unidirectional and unsuitable for true bidirectional AC-coupled lines. For RS-485 or CAN, a bidirectional TVS (e.g., PTVS3V3Z2UTR) or back-to-back diode configuration is required. Using this part on bidirectional lines risks failure during negative transients due to lack of reverse conduction path.
What is the recommended PCB layout for optimal surge performance?
Place PTVS6V3Z1UCL as close as possible to the protected connector or IC pin, with minimal trace length (<2 mm) between the device and ground plane. Use a dedicated thermal pad connected to a solid internal ground plane via ≥4 thermal vias (0.3 mm diameter) to ensure effective heat dissipation during 40 A surges.
Does PTVS6V3Z1UCL require derating at elevated ambient temperatures?
Yes - while the junction temperature rating is 150 °C, the peak pulse current (IPPM) must be reduced above 25 °C ambient. At 85 °C ambient, IPPM derates to approximately 28 A per Nexperia's thermal derating curve (Figure 12 in datasheet v1). Layout thermal resistance and airflow must be considered for sustained surge duty.
