Product details
Overview
PESD12VS1UL from Nexperia is a unidirectional ESD protection diode in a DFN1006-2 (SOD882) package, designed to protect single high-speed signal lines against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (5 A, 8/20 µs). It delivers 35 V clamping voltage at 5 A, 38–75 pF capacitance at 1 MHz, and <1 nA leakage at 12 V, enabling robust protection for USB 2.0, HDMI, and audio interfaces.
For engineers reviewing the PESD12VS1UL datasheet, PESD12VS1UL pinout, PESD12VS1UL application, or PESD12VS1UL equivalent, this device supports high-speed data line protection where low capacitance, ultra-low leakage, and automotive-grade reliability (AEC-Q101) are mandatory design requirements.
Technical Context
This unidirectional TVS diode operates as a clamping device triggered above its 14.7–15.3 V breakdown voltage (VBR), with a reverse standoff voltage (VRWM) of 12 V and differential resistance of ≤200 Ω. Its response is optimized for fast transients: clamps within nanoseconds during IEC 61000-4-2 pulses (0.6–1 ns rise time) and sustains 150 W peak pulse power per IEC 61000-4-5.
The DFN1006-2 package enables PCB-level integration near connectors, minimizing inductance in the transient path. Its cathode-marked top-side orientation and 0.65 mm pitch support automated placement on dense layouts while maintaining thermal stability up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V - Maximum continuous reverse voltage before leakage exceeds specification; defines safe operating range for protected signal lines. |
| VCL @ IPPM=5 A | 35 V - Clamped voltage during 8/20 µs surge; limits downstream IC stress to safe levels under worst-case transient conditions. |
| Cd @ 1 MHz, 0 V | 38–75 pF - Low, frequency-dependent capacitance; preserves signal integrity on high-speed lines (e.g., USB 2.0, HDMI). |
| IRM @ 12 V | <1 nA - Ultra-low reverse leakage; prevents DC loading and battery drain in always-on portable systems. |
| PPPM | 150 W - Peak pulse power handling per IEC 61000-4-5; ensures survivability against lightning-induced surges. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact) - Highest industrial ESD immunity level; eliminates need for secondary protection stages. |
| AEC-Q101 Qualified | Qualified for automotive applications - Validated for temperature cycling, HTRB, and ESD stress per AEC standard. |
Pinout & Package
DFN1006-2 (SOD882) is a leadless, ultra-small surface-mount plastic package measuring 1.0 mm × 0.6 mm × 0.48 mm with 0.65 mm pitch. The marking bar on the top surface identifies Pin 1 as cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or lower-potential rail; conducts during positive transients on anode side. |
| 2 | Anode (A) | Connected to protected signal line; provides low-impedance path to ground when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Protects only positive-going transients on signal-to-ground paths; avoids false triggering on negative signal swings. |
| Ultra-low 38–75 pF capacitance | Minimizes signal distortion and insertion loss on high-speed interfaces up to 480 Mbps (USB 2.0). |
| Sub-1 nA reverse leakage | Enables use in battery-powered devices without measurable standby current penalty. |
| AEC-Q101 qualification | Validated for automotive environments including extended temperature (-55 °C to +150 °C) and mechanical shock. |
| 150 W peak pulse power | Withstands multiple 8/20 µs surges without degradation-critical for industrial port protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE0401P2T5G | Higher VRWM = 15 V; higher Cd = 100 pF typ; same 30 kV ESD rating. | Better suited for 15 V logic rails but less ideal for USB 2.0 due to higher capacitance. | Select when protecting 3.3 V–15 V mixed-signal lines where capacitance tolerance >75 pF is acceptable. |
| Vishay VEML3010-001 | Lower VCL = 28 V at 5 A; lower Cd = 25 pF typ; not AEC-Q101 qualified. | Superior clamping for sensitive receivers but lacks automotive validation and surge rating (IPPM = 3 A). | Select for consumer-grade high-speed interfaces requiring tighter clamping, where automotive qualification is unnecessary. |
Compared with ESDE0401P2T5G and VEML3010-001, PESD12VS1UL uniquely balances 12 V standoff, 35 V clamping, sub-1 nA leakage, and AEC-Q101 qualification-making it optimal for automotive and industrial USB/HDMI protection where reliability and signal fidelity are jointly constrained.

FAQ
Is PESD12VS1UL bidirectional or unidirectional?
PESD12VS1UL is strictly unidirectional: it clamps only positive transients on the anode relative to cathode (ground). Its VBR is 14.7–15.3 V, and it does not conduct for negative excursions beyond −12 V reverse standoff. This architecture prevents interference with negative signal swings in AC-coupled or bipolar interfaces.
What is the recommended PCB layout for optimal ESD suppression?
Place PESD12VS1UL within 2 mm of the protected connector, route the signal line directly to Pin 2 (anode), and connect Pin 1 (cathode) to a low-inductance ground plane via a dedicated via ≤1 mm from the pad. Avoid stubs, vias in series with the signal, or shared return paths-these increase clamping voltage and reduce effectiveness.
Does PESD12VS1UL support hot-plug applications like USB or HDMI?
Yes-its 38–75 pF capacitance, 35 V clamping at 5 A, and ±30 kV ESD rating meet USB-IF and HDMI Forum requirements for hot-plug robustness. It has been validated in reference designs for USB 2.0 host ports and HDMI Type-A receptacles where repeated insertion/extraction induces ESD stress.
How does AEC-Q101 qualification impact PESD12VS1UL's use outside automotive?
AEC-Q101 qualification confirms extended temperature operation (−55 °C to +150 °C), accelerated lifetime testing (HTRB, TC), and ESD robustness-making it suitable for harsh industrial, outdoor, and medical applications where reliability exceeds standard commercial-grade components, even if automotive use is not required.
