Product details
Overview
PTVS5V0D1UCL 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 5 V reverse standoff voltage (VRWM), 7.5 V typical clamping voltage at 65 A, 230 pF capacitance at 1 MHz, and 30 kV ESD rating for both contact and air discharge.
For engineers reviewing the PTVS5V0D1UCL datasheet, PTVS5V0D1UCL pinout, PTVS5V0D1UCL application, or PTVS5V0D1UCL equivalent, this page delivers verified electrical parameters, validated DFN1006-2 terminal mapping, real-world protection use cases, and direct alternative comparisons for portable electronics, power supply rails, and low-capacitance signal line protection.
Technical Context
This TVS diode operates as a unidirectional clamp on a single data or power line, conducting only when reverse voltage exceeds 5.1 V breakdown (VBR at 1 mA). Its ultra-low 7.5 V clamping at 65 A (8/20 µs) limits transient energy dissipation while maintaining signal integrity.
The device uses silicon PN-junction technology with optimized doping and geometry to achieve 230 pF capacitance at 0 V bias-critical for high-speed USB, I²C, and GPIO lines-and sustains 150 °C junction temperature under surge stress per IEC 61000-4-5 compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V reverse standoff voltage - ensures no conduction during normal 5 V rail operation |
| VBR | 5.1 V min breakdown at 1 mA - defines precise turn-on threshold for overvoltage response |
| VCL | 7.5 V typ. clamping at 65 A - limits peak line voltage during 8/20 µs surge to safe levels |
| Cd | 230 pF at 1 MHz, 0 V - enables use on 10–40 Mbps digital interfaces without signal distortion |
| ESD Rating | 30 kV contact / 30 kV air per IEC 61000-4-2 - exceeds Level 4 immunity requirements |
| IPP | 73 A average measured surge current - confirms robustness beyond rated 65 A peak pulse |
| Tj max | 150 °C maximum junction temperature - supports operation in compact, thermally constrained PCB layouts |
Pinout & Package
PTVS5V0D1UCL is housed in a leadless DFN1006-2 (SOD882P-1) package measuring 1.02 mm × 0.62 mm × 0.45 mm with 0.65 mm pitch. The package features a transparent top view with cathode band marking ('9K') and is optimized for automated reflow assembly using the recommended 0.1 mm stencil thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line; conducts surge current toward ground when reverse-biased above VBR |
| 2 (A) | Anode | Connected to system ground; completes clamping path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects positive-polarity lines only - avoids false triggering on bidirectional signals |
| Ultra-low clamping voltage | 7.5 V typical at 65 A - minimizes voltage overshoot on 5 V systems, reducing risk of downstream IC damage |
| Low capacitance | 230 pF - preserves signal rise/fall times on high-speed interfaces like USB 2.0 and I²C |
| High ESD immunity | 30 kV contact/air - eliminates need for secondary ESD protection in space-constrained designs |
| Miniature footprint | DFN1006-2 (1.02 × 0.62 mm) - saves >60% board area vs. SOD-123 packages |
Applications
| USB 2.0 Data Lines | 5 V Power Rail Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals against ESD and cable-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between each data line and ground, clamping transients before they reach the USB transceiver. Use Value: 230 pF capacitance prevents signal integrity degradation at 480 Mbps, while 7.5 V clamping keeps voltage within USB 2.0 receiver tolerance (–0.5 V to 3.6 V). | Use Scenario: Safeguarding 5 V input rails in battery-powered IoT sensors and wearables from hot-plug and load-dump transients. IC Role / Device Role / Timing Role: Standoff diode connected anode-to-ground, cathode-to-rail, absorbing positive surges before reaching LDO or MCU VDD pins. Use Value: 65 A surge rating handles 100 V/1 Ω IEC 61000-4-5 waveforms, and 5 V VRWM ensures zero leakage during nominal operation. |
| I²C Bus Lines | GPIO Protection in Handheld Devices |
Use Scenario: Shielding SDA/SCL lines in smart home controllers exposed to ESD during user interaction or connector mating. IC Role / Device Role / Timing Role: Low-capacitance TVS on each bus line referenced to ground, enabling fast recovery after ESD event without bus lockup. Use Value: Sub-1 nA IRM at 5 V ensures no DC loading on pull-up resistors; 30 kV ESD rating meets IEC 61000-4-2 Level 4 compliance. | Use Scenario: Hardening tactile button inputs and LED driver outputs in medical wearables against electrostatic discharge during handling. IC Role / Device Role / Timing Role: Cathode tied to GPIO, anode to ground - clamps negative transients on open-drain outputs and positive spikes on input pins. Use Value: 7.5 V clamping prevents latch-up in 5 V-tolerant microcontrollers; DFN1006-2 footprint allows placement directly at connector pads. |
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 × 2.7 mm); 5.0 V VRWM; 10.8 V VCL at 43.5 A | Higher clamping voltage and larger footprint - suitable for non-high-speed, higher-power industrial rails | Select when board space is unconstrained and surge energy exceeds 65 A but signal speed is ≤1 Mbps |
| TPD1E05U06DPYR | DFN1006-2 package; 5.0 V VRWM; 7.5 V VCL at 5 A; 0.6 pF capacitance | Lower surge rating (5 A vs. 65 A); optimized for ESD-only, not surge protection | Select only for pure ESD protection on ultra-high-speed lines (e.g., USB 3.0), not for IEC 61000-4-5 compliance |
Compared with SMAJ5.0A and TPD1E05U06DPYR, PTVS5V0D1UCL uniquely balances 65 A surge capability, 7.5 V clamping, and 230 pF capacitance in a 1.02 mm × 0.62 mm footprint-making it optimal for space-limited 5 V interfaces requiring both ESD and surge immunity.

FAQ
Is PTVS5V0D1UCL suitable for bidirectional signal lines like RS-485?
No. PTVS5V0D1UCL is unidirectional and protects only positive-going transients on a line referenced to ground. For bidirectional lines such as RS-485, a symmetric (bidirectional) TVS like PTVS5V0S1UR must be used to clamp both polarities equally.
What is the thermal resistance (RθJA) of the DFN1006-2 package under standard JEDEC conditions?
The datasheet does not specify RθJA for PTVS5V0D1UCL. Thermal performance depends on PCB copper area, layer count, and via placement. Nexperia recommends ≥20 mm² of 1 oz copper connected to both terminals for optimal surge dissipation in repeated pulse scenarios.
Can PTVS5V0D1UCL replace a Zener diode in overvoltage protection circuits?
No. While both are PN-junction devices, PTVS5V0D1UCL is optimized for transient suppression-not steady-state regulation. Its VBR (5.1 V min) and VCL (7.5 V typ.) lack the tight tolerance and low dynamic impedance required for precision voltage clamping during continuous overvoltage.
Does the '9K' marking on the device correspond to the full part number?
Yes. '9K' is the official Nexperia marking code for PTVS5V0D1UCL, defined in Table 4 of the datasheet. It is laser-etched on the top surface of the DFN1006-2 package and used for visual identification and traceability during assembly and inspection.
