Product details
Overview
PESD12VS1ULS from Nexperia is a unidirectional ESD protection diode in a DFN1006BD-2 (SOD882BD) package, designed to protect one signal line against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (5 A, 8/20 µs). It delivers 12 V reverse standoff voltage, 38 pF typical capacitance at 1 MHz, and 19 V clamping voltage at 1 A, making it suitable for high-speed USB 2.0 and HDMI data lines.
For engineers reviewing the PESD12VS1ULS datasheet, PESD12VS1ULS pinout, PESD12VS1ULS application, or PESD12VS1ULS equivalent, key selection criteria include low clamping voltage under transient stress, ultra-low leakage (<1 nA), side-wettable flanks for automated optical inspection, AEC-Q101 qualification, and sub-1 mm² footprint for space-constrained portable electronics.
Technical Context
This device operates as a single-line unidirectional TVS diode with cathode-anode polarity, leveraging silicon avalanche breakdown for fast response (<1 ns) to ESD events. Its clamping behavior is characterized by dynamic resistance of 0.6 Ω at 10 A TLP pulse, enabling effective voltage limiting during transients.
The DFN1006BD-2 package integrates side-wettable flanks to support solder-joint quality verification via AOI, while its 0.65 mm pitch and 1.0 mm × 0.6 mm body enable placement adjacent to high-speed connectors-critical for minimizing inductance in ESD current paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V reverse standoff voltage - ensures no conduction during normal 12 V signal operation, preserving signal integrity. |
| VCL @ IPP = 1 A | 19 V clamping voltage - limits transient voltage to safe levels for downstream 3.3 V or 5 V ICs. |
| Cd @ 1 MHz | 38 pF typical capacitance - enables use on USB 2.0 (480 Mbps) and audio interfaces without signal degradation. |
| IPP | 5 A peak pulse current (8/20 µs) - meets IEC 61000-4-5 Level 3 surge immunity requirements. |
| IRM | <1 nA reverse leakage at 12 V - prevents DC loading on sensitive analog or reference lines. |
| ESD Rating | ±30 kV contact discharge per IEC 61000-4-2 Level 4 - exceeds industrial and automotive ESD immunity standards. |
| AEC-Q101 | Qualified - supports deployment in automotive infotainment and ADAS sensor interfaces without additional qualification. |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless ultra-small surface-mount plastic package with side-wettable flanks; dimensions 1.0 mm × 0.6 mm × 0.47 mm, 0.65 mm pitch, cathode indicated by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or protected line return path; polarity defines unidirectional clamping direction. |
| 2 | Anode (A) | Connected to the signal line requiring protection; conducts transient current to ground when voltage exceeds VBR (~15 V). |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder joints on both top and side surfaces-critical for high-reliability automotive PCB assembly. |
| Ultra-low leakage current | <1 nA at 12 V reverse bias minimizes power loss and avoids drift in precision analog front-ends or battery-monitoring circuits. |
| Low clamping voltage | 19 V at 1 A ensures protected ICs (e.g., USB PHYs rated for 20 V abs max) remain within safe operating area during ESD events. |
| Small footprint | 1.0 mm × 0.6 mm body allows placement directly at board edge connectors-reducing trace inductance and improving ESD suppression efficacy. |
| AEC-Q101 qualification | Validated for temperature cycling, HTRB, and ESD stress per automotive discrete semiconductor standard-enabling drop-in use in vehicle ECUs. |
Applications
| USB 2.0 Data Lines | HDMI Signal 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 ESDE0402E01200 | Same 12 V VRWM, but higher 50 pF typical capacitance and no AEC-Q101 qualification. | Suitable for consumer-grade USB ports but not automotive environments requiring qualified components. | Select when cost sensitivity outweighs automotive compliance and lower capacitance is non-critical. |
| Vishay VE1206M12G | 12 V VRWM, 45 pF typical capacitance, 20 V clamping at 1 A, AEC-Q101 qualified, but larger 1.25 mm × 0.65 mm DFN package. | Acceptable for space-tolerant automotive modules but less optimal for ultra-dense portable PCBs. | Choose when higher surge robustness (6 A IPP) is prioritized over minimal footprint. |
Compared with ESDE0402E01200 and VE1206M12G, PESD12VS1ULS uniquely balances AEC-Q101 qualification, 38 pF capacitance, and 1.0 mm × 0.6 mm footprint-making it optimal for automotive infotainment and miniaturized USB 2.0 designs where board space and reliability are co-constrained.

FAQ
What is the maximum operating temperature for PESD12VS1ULS?
The PESD12VS1ULS has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance (Rthj-a) is not specified in the datasheet, but the 0.47 mm height and copper-exposed pad design support efficient heat dissipation in standard FR-4 PCB layouts with adequate copper pour.
Does PESD12VS1ULS support bidirectional ESD protection?
No. PESD12VS1ULS is strictly unidirectional, with defined anode (pin 2) and cathode (pin 1) terminals. It protects only signals referenced to ground with positive polarity. For bidirectional protection, two devices in series opposition or a dedicated bidirectional part like PESD5V0S1UL must be used.
How does the side-wettable flank feature aid manufacturing?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) systems to verify solder fillet formation on the lateral edges of the terminals-enabling 100% solder-joint quality screening without X-ray, which is essential for automotive and medical PCB assembly audits.
Can PESD12VS1ULS be used on 5 V logic lines?
Yes. With a 12 V reverse standoff voltage (VRWM) and 14.7–15.3 V breakdown voltage (VBR), PESD12VS1ULS remains non-conductive during normal 5 V operation while clamping transients to ≤19 V at 1 A-well below the absolute maximum ratings of most 5 V logic ICs (typically 6–7 V).
