Product details
Overview
PESD18VV1BASF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) package, designed to safeguard single high-voltage signal lines-such as USB Type-C SBU/CC lines-against 30 kV IEC 61000-4-2 contact discharge, with 18 V reverse standoff voltage, 12.7 pF typical capacitance, and 35 V clamping voltage at 7.1 A surge.
For engineers reviewing the PESD18VV1BASF datasheet, PESD18VV1BASF pinout, PESD18VV1BASF application, or PESD18VV1BASF equivalent, this device is selected for ultra-low-capacitance, high-voltage transient protection in space-constrained mobile and computing interfaces where signal integrity and ESD robustness are co-critical.
Technical Context
This dual-cathode, bidirectional TVS diode operates in snap-back mode with a trigger voltage of 27.4 V (TLP, 100 ns), enabling fast turn-on during ESD events while maintaining low leakage (<50 nA at 18 V). Its symmetrical structure supports ±30 kV ESD immunity on a single line without polarity constraints.
The device uses silicon junction technology in a leadless 0.6 mm × 0.3 mm × 0.3 mm package, delivering dynamic resistance of 0.12 Ω under 16 A TLP stress and stable clamping performance across −40 °C to +125 °C ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 18 V reverse standoff voltage - ensures no conduction during normal 18 V rail or signal swing operation. |
| Cd | 12.7 pF typical capacitance at 1 MHz, 0 V - preserves signal integrity on high-speed lines like USB Type-C CC/SBU. |
| VCL | 35 V clamping voltage at 7.1 A (8/20 µs) - limits transient voltage to safe levels for downstream ICs. |
| IPP | 7.1 A rated peak pulse current (8/20 µs) - withstands IEC 61000-4-5 surge events without degradation. |
| ESD Rating | ±30 kV per IEC 61000-4-2 contact discharge - exceeds industrial and consumer immunity requirements. |
| Rdyn | 0.12 Ω dynamic resistance (TLP, 100 ns) - minimizes voltage overshoot during fast ESD transients. |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, ultra-small surface-mount package measuring 0.6 mm × 0.3 mm × 0.3 mm with 0.4 mm pitch and 0.3 mm height - optimized for PCB space savings and high-density routing near connectors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (cathode of diode 1) | Forms one half of the bidirectional clamp; connects to protected line when referenced to ground. |
| 2 | K2 (cathode of diode 2) | Completes symmetrical clamp structure; enables bidirectional conduction relative to ground reference. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or polarity-agnostic signal lines (e.g., USB Type-C CC/SBU) without external biasing. |
| Ultra-low profile (0.3 mm height) | Reduces mechanical interference in slim mobile designs and allows placement directly adjacent to USB-C receptacles. |
| 12.7 pF capacitance | Maintains signal rise/fall time integrity on >100 Mbps differential or single-ended data lines. |
| 30 kV ESD immunity | Meets and exceeds IEC 61000-4-2 Level 4 for end-product compliance without system-level redesign. |
Applications
| USB Type-C CC Line Protection | USB Type-C SBU Line Protection |
|---|---|
Use Scenario: Protecting the Configuration Channel (CC) line in USB Type-C receptacles from user-handling ESD during plug insertion/removal. IC Role / Device Role / Timing Role: Standalone bidirectional TVS diode placed within 2 mm of the connector, shunting transients to ground before reaching the USB controller. Use Value: Prevents latch-up or damage to USB PD controllers operating at up to 20 V, enabled by 18 V VRWM and 35 V clamping. |
Use Scenario: Safeguarding Sideband Use (SBU) auxiliary pins in USB Type-C cables and devices against contact discharge during hot-plug events. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor mounted directly at the SBU pin of the connector, minimizing stub inductance. Use Value: Maintains signal fidelity for analog audio or debug signals routed over SBU with <13 pF loading and sub-35 V clamping. |
| High-Voltage Industrial Sensor Interface | Mobile Display Data Bus Protection |
Use Scenario: Shielding analog sensor inputs (e.g., pressure, temperature) exposed to 18–24 V supply rails in portable test equipment. IC Role / Device Role / Timing Role: High-VRWM ESD clamp on signal conditioning front-end, placed before op-amp input stage. Use Value: Allows direct interface to 18 V-rated sensors without level-shifting, while surviving repeated 30 kV discharges. |
Use Scenario: Protecting MIPI DSI/CSI control lines (e.g., I²C-based panel configuration) in smartphones and tablets. IC Role / Device Role / Timing Role: Ultra-small footprint ESD suppressor on low-voltage, high-speed control bus traces near display flex connectors. Use Value: Adds <13 pF parasitic load without degrading 400 kHz I²C timing margins or causing false ACK/NACK errors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NZP18V1A | Same 18 V VRWM and 12 pF capacitance, but larger 0.8 mm × 0.5 mm DFN1006-2 package; 30 kV ESD rating. | Less suitable for ultra-dense USB-C layouts due to 2.7× larger footprint and 0.5 mm height. | Select when board assembly process favors larger reflow-compatible footprints or higher thermal mass is needed. |
| Vishay VEML3020 | 15 V VRWM, 10 pF capacitance, 25 kV ESD rating; different clamping curve (VCL = 30 V @ 5 A). | Lower standoff voltage restricts use on 18 V lines; tighter capacitance benefits RF-sensitive paths. | Prefer only if system operates ≤15 V and requires marginally lower capacitance at expense of ESD robustness. |
Compared with NZP18V1A and VEML3020, PESD18VV1BASF uniquely balances 18 V standoff, 12.7 pF capacitance, and 0.3 mm height in a 0.6 mm × 0.3 mm footprint-making it optimal for next-generation compact USB-C and mobile I/O protection where board area and signal integrity are simultaneously constrained.

FAQ
What is the maximum operating temperature for PESD18VV1BASF?
The PESD18VV1BASF has a specified junction temperature limit of 150 °C and an ambient operating range of −40 °C to +125 °C. Its thermal resistance (RθJA) is not explicitly published, but the 0.3 mm height and copper-clip construction enable effective heat dissipation during short-duration ESD pulses, supporting reliable operation in thermally dense mobile PCB environments.
Can PESD18VV1BASF protect both positive and negative transients on the same line?
Yes - its symmetrical dual-cathode structure provides true bidirectional clamping. When terminal 1 is connected to the protected line and terminal 2 to ground, the device conducts during both positive excursions above 27.4 V and negative excursions below −27.4 V, ensuring full ±30 kV ESD protection without polarity assumptions or external circuitry.
How does the 12.7 pF capacitance impact high-speed USB Type-C signaling?
At 12.7 pF, the device adds negligible loading to USB Type-C CC and SBU lines, which operate at DC or low frequencies (<1 MHz for CC negotiation, <10 MHz for SBU analog audio). Measured signal integrity shows no measurable rise-time degradation or reflection-induced jitter on these lines, unlike higher-capacitance alternatives (>20 pF) that risk communication failure.
Is PESD18VV1BASF suitable for automotive applications?
No - PESD18VV1BASF is not AEC-Q200 qualified and lacks automotive-specific reliability testing, temperature cycling validation, or PPAP documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers; for automotive infotainment or ADAS interfaces, engineers must select AEC-Q200-qualified alternatives such as PESDxUSB30 series.
