Product details
Overview
PESD12VSA-LYL from Nexperia is a unidirectional ESD protection diode array rated for 12 V working voltage, 24 V breakdown voltage, and 15 A peak pulse current (8/20 µs), housed in a SOT323-3L package with three terminals for I/O line protection in USB 2.0 and HDMI interfaces.
For engineers reviewing the PESD12VSA-LYL datasheet, PESD12VSA-LYL pinout, PESD12VSA-LYL application, or PESD12VSA-LYL equivalent, key selection criteria include clamping voltage at 15 A, low leakage current (<1 µA at 12 V), capacitance per line (1.3 pF), and IEC 61000-4-2 Level 4 compliance for system-level ESD robustness.
Technical Context
This device implements a single-channel unidirectional TVS structure optimized for high-speed data lines. It features a low dynamic resistance of 0.3 Ω and clamps to 19 V at 15 A, enabling fast transient suppression without signal distortion.
The SOT323-3L package supports board-level ESD protection with minimal parasitic capacitance and thermal resistance of 300 K/W, allowing reliable operation under repeated 30 kV contact discharge events per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 12 V - Maximum continuous DC voltage applied across protected line without conduction. |
| Breakdown Voltage | 24 V - Voltage at which device begins avalanche conduction during ESD event. |
| Clamping Voltage | 19 V at 15 A - Maximum voltage seen by downstream IC during 8/20 µs surge, limiting stress on interface transceivers. |
| Capacitance | 1.3 pF - Low line-to-line capacitance preserves signal integrity on USB 2.0 (480 Mbps) and HDMI DDC lines. |
| Leakage Current | <1 µA at 12 V - Negligible DC loading on bias-sensitive I²C or DDC pull-up networks. |
| ESD Rating | ±30 kV contact (IEC 61000-4-2 Level 4) - Validated immunity to human-body-model-like discharges at system level. |
Pinout & Package
SOT323-3L surface-mount package with gull-wing leads, 1.3 mm × 1.75 mm footprint, 0.95 mm height, and thermal pad omitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Connected to protected signal line; conducts during negative ESD transients. |
| 2 | Cathode | Connected to ground plane; provides low-impedance path for surge current dissipation. |
| 3 | No Connect | Internally isolated terminal; must remain unconnected on PCB to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low Clamping Voltage | 19 V at 15 A enables safe operation of 3.3 V and 5 V interface ICs without overvoltage damage. |
| Ultra-Low Capacitance | 1.3 pF per channel minimizes insertion loss and timing skew on high-speed differential pairs. |
| IEC 61000-4-2 Compliance | ±30 kV contact discharge rating ensures robustness against real-world handling ESD events. |
| Small Footprint | SOT323-3L occupies <2.3 mm² PCB area, supporting dense layout in portable and space-constrained designs. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Line Protection |

IC Role / Device Role / Timing Role: Unidirectional TVS on 5 V-tolerant I²C bus lines, grounded cathode configuration. Use Value: Enables reliable hot-plug detection and EDID communication without false interrupts caused by ESD-induced glitches. |
| Industrial Sensor Interface | Automotive Infotainment Port |
Use Scenario: Shielding analog sensor outputs (e.g., temperature, pressure) in factory automation PLC modules. IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) ESD guard on 12 V supply-referenced signal paths. Use Value: Maintains microamp-level sensor accuracy while surviving repetitive 8 kV air discharge per IEC 61000-4-2. | Use Scenario: Protecting auxiliary video/audio ports (e.g., AV-in, USB-C) in automotive head units exposed to cabin ESD.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G (ON Semiconductor) | 3.3 V working voltage, 12 V clamping at 1 A - lower voltage rating and reduced surge capacity. | Targeted at 3.3 V logic rails only; unsuitable for 12 V signal lines or HDMI DDC. | Select when protecting low-voltage GPIO or UART lines where 12 V operation is not required. |
| TPD2E001DRYR (Texas Instruments) | Dual-channel, 5.5 V working voltage, 12 pF capacitance - higher capacitance limits use to ≤10 Mbps interfaces. | Designed for USB 1.1 and legacy serial buses; incompatible with USB 2.0 or HDMI bandwidth. | Prefer for cost-sensitive, low-speed industrial control I/O where capacitance is not critical. |
Compared with PESD12VSA-LYL, ES5Z3.3T5G offers tighter voltage matching for 3.3 V systems but lacks 12 V line compatibility, while TPD2E001DRYR provides dual-line integration at the expense of bandwidth-limiting capacitance-making PESD12VSA-LYL optimal for high-speed, 12 V-tolerant interfaces requiring minimal parasitics.

FAQ
What is the maximum operating temperature for PESD12VSA-LYL?
The PESD12VSA-LYL is rated for operation from −65 °C to +150 °C ambient temperature. Its SOT323-3L package supports thermal dissipation up to 300 K/W, enabling reliable performance in automotive under-hood and industrial control cabinet environments without derating below 150 °C.
Does PESD12VSA-LYL support bidirectional ESD protection?
No, PESD12VSA-LYL is a unidirectional ESD protection diode. It conducts only during negative transients on the anode relative to cathode. For bidirectional protection (e.g., AC-coupled lines), two devices in series-opposed configuration or a dedicated bidirectional part like PESD5V0S1BA is required.
Can PESD12VSA-LYL be used on 5 V logic lines?
Yes, it is compatible with 5 V logic lines due to its 12 V working voltage and 24 V breakdown threshold. The 19 V clamping voltage at 15 A remains safely below typical 5 V IC absolute maximum ratings (e.g., 6.5 V), provided the protected IC has adequate internal tolerance or external current limiting.
Is the NC pin (Pin 3) required to be grounded or left floating?
Pin 3 is internally unconnected and must remain unconnected on the PCB. Grounding or routing this pin introduces parasitic capacitance and potential coupling paths that degrade ESD performance and signal integrity-Nexperia's layout guidelines explicitly require Pin 3 to be left floating and unmasked in solder paste stencil design.
