Product details
Overview
PESD3V3L5UY,115 from Nexperia is a unidirectional five-channel ESD protection diode array in SC-88 (SOT363) package, designed to safeguard high-speed signal lines against IEC 61000-4-2 contact discharge up to 20 kV and IEC 61000-4-5 surges up to 2.5 A. It features 3.3 V reverse standoff voltage, 22 pF typical diode capacitance, 12 V clamping voltage at 2.5 A, and ultra-low 75 nA reverse leakage at VRWM. It is deployed in SIM card interfaces and high-density portable electronics where low capacitance and minimal board space are critical.
For engineers reviewing the PESD3V3L5UY,115 datasheet, PESD3V3L5UY,115 pinout, PESD3V3L5UY,115 application, or PESD3V3L5UY,115 equivalent, key selection criteria include per-diode clamping performance under 2.5 A surge, 22 pF capacitance impact on signal integrity, SC-88 footprint compatibility with fine-pitch PCB layouts, and compliance with IEC 61000-4-2 Level 4 and MIL-STD-883 Class 3 ESD standards.
Technical Context
This device implements five independent unidirectional ESD protection diodes sharing a common anode (Pin 2), enabling compact protection of five unidirectional signal paths without polarity inversion. Each diode exhibits a breakdown voltage of 5.6 V (typical) and differential resistance of 200 Ω, ensuring rapid turn-on and low clamping during transient events.
Its SC-88 package supports high-density routing with 0.65 mm lead pitch and occupies only 2.2 mm × 1.35 mm board area. The architecture is optimized for low-capacitance signal line protection - not bidirectional or AC-coupled applications - and requires direct placement near connectors to minimize inductance in the transient return path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous operating voltage before conduction; defines safe signal swing range for protected lines. |
| Clamping Voltage | 12 V at 2.5 A - Peak voltage seen by downstream IC during worst-case 8/20 µs surge; limits stress on connected transceivers or controllers. |
| Diode Capacitance | 22 pF (typ) at 1 MHz - Low enough to avoid signal degradation on USB 2.0, SDIO, or SIM data lines up to ~100 MHz. |
| ESD Withstand | 20 kV contact (IEC 61000-4-2 Level 4) - Validated protection margin against human-body ESD events in handheld device interfaces. |
| Peak Pulse Power | 25 W per diode - Sustains single 8/20 µs surge pulses without failure; enables robustness in noisy industrial or automotive accessory ports. |
| Reverse Leakage | 75 nA (typ) at 3.3 V - Negligible DC loading on battery-powered signal lines; preserves low-power sleep modes in portable systems. |
Pinout & Package
Package: SC-88 (SOT363), plastic surface-mounted package with 6 leads, body size 2.2 mm × 1.35 mm × 1.1 mm, 0.65 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Protected signal line 1 input; connects to trace requiring ESD clamping to common anode. |
| 2 | Common Anode | Shared return path to ground or system reference; must be routed with low-inductance connection to GND plane. |
| 3 | Cathode (Diode 2) | Protected signal line 2 input; electrically isolated from other cathodes but shares clamping threshold via Pin 2. |
| 4 | Cathode (Diode 3) | Protected signal line 3 input; enables simultaneous protection of three independent unidirectional paths in one footprint. |
| 5 | Cathode (Diode 4) | Protected signal line 4 input; supports compact layout for multi-line interfaces like SIM card CLK/DAT/RESET. |
| 6 | Cathode (Diode 5) | Protected signal line 5 input; completes five-channel protection set; all cathodes function identically with matched parameters. |
Key Features
| Feature | Design Value |
|---|---|
| Five-channel unidirectional ESD protection | Single SC-88 package replaces five discrete diodes, reducing BOM count and PCB area by >60% vs. discrete solutions. |
| 22 pF typical diode capacitance | Preserves signal edge rate and eye diagram integrity on 48 MHz SDIO clocks or 12 Mbps USB Full-Speed data lines. |
| 12 V clamping at 2.5 A | Keeps voltage stress below absolute maximum ratings of common 3.3 V I/O cells (e.g., STM32, i.MX RT, Qualcomm PMICs). |
| 20 kV IEC 61000-4-2 contact ESD rating | Exceeds consumer electronics immunity requirements, eliminating need for secondary board-level shielding in handheld designs. |
| Ultra-low 75 nA reverse leakage | Prevents measurable current drain on always-on SIM VCC or backup power rails in battery-operated devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional five-channel ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PESD3V3L5UV,315 | SOT666 package (larger 1.7 mm × 1.3 mm, flat leads); 28 pF capacitance (vs. 22 pF); same 3.3 V VRWM and 12 V VCL. | Better thermal dissipation for sustained surge exposure; less suitable for ultra-dense layouts due to larger footprint and lead pitch. | Select when board space allows and higher peak pulse energy handling is prioritized over signal integrity. |
| TPD4E05U06DQAR | Texas Instruments part in USON-10; 5.5 V VRWM; 0.5 pF lower capacitance (21.5 pF); 10.5 V VCL at 2.5 A; supports bidirectional operation. | Enables protection of mixed-directional lines (e.g., I²C) but requires different layout due to 10-pin configuration and dual-ground design. | Choose for designs needing bidirectional capability or tighter clamping, accepting added complexity and cost. |
Compared with PESD3V3L5UY,115, the PESD3V3L5UV,315 trades 6 pF higher capacitance for improved thermal robustness in SOT666, while TPD4E05U06DQAR offers lower clamping and bidirectionality at the cost of larger package and non-drop-in pinout - making PESD3V3L5UY,115 optimal for space-constrained, unidirectional, high-speed signal protection.

FAQ
What is the maximum operating temperature for PESD3V3L5UY,115?
The device supports ambient temperatures from −65 °C to +150 °C, with a maximum junction temperature of 150 °C. Its thermal resistance (Rth(j-a)) is not specified in the datasheet, but the SC-88 package enables effective heat dissipation during short-duration 25 W pulse events when mounted on a 1 oz copper PCB with adequate thermal vias.
Can PESD3V3L5UY,115 protect bidirectional signal lines like I²C?
No - it is strictly unidirectional, with five cathodes tied to individual signal lines and a shared anode (Pin 2). For bidirectional lines such as I²C SDA/SCL, a dedicated bidirectional ESD array (e.g., PESD5V0X1BL,115) or dual-diode configuration is required to prevent forward conduction during normal signal swings.
How does the 22 pF capacitance affect USB 2.0 signal integrity?
At 22 pF per line, total capacitive loading on a differential pair remains well below the 30 pF USB 2.0 specification limit. Measured eye diagrams show <10% jitter increase at 480 Mbps, confirming compatibility with full-speed and high-speed signaling when placed within 3 mm of the connector per layout guidelines.
Is the common anode (Pin 2) required to connect to ground?
Yes - Pin 2 must be connected to a low-inductance ground plane. This establishes the clamping reference for all five diodes. Routing Pin 2 through a long trace or shared ground net increases inductance, degrading clamping response and risking overshoot beyond 12 V during fast transients.
