Product details
Overview
PESD3V3S5UD,115 from Nexperia is a fivefold unidirectional ESD protection diode array in SOT457 (SC-74) package, designed to protect up to five signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 3.3 V reverse standoff voltage, 12 V clamping voltage at 20 A surge, and 215 pF typical diode capacitance. It serves in high-speed data line protection for portable electronics and SIM card interfaces.
For engineers reviewing the PESD3V3S5UD,115 datasheet, PESD3V3S5UD,115 pinout, PESD3V3S5UD,115 application, or PESD3V3S5UD,115 equivalent, key selection criteria include low clamping voltage under 20 A surge, ultra-low leakage (<500 nA at 3.3 V), compact 6-pin SOT457 footprint, and compliance with IEC 61000-4-2/4-5 for handheld and peripheral designs.
Technical Context
This device implements five independent unidirectional TVS diodes sharing a common anode (Pin 2), enabling simultaneous protection of five signal lines referenced to ground. Each diode features a breakdown voltage of 5.3–5.9 V and clamps transients to ≤12 V at 20 A (8/20 µs), meeting IEC 61000-4-2 level 4 and IEC 61000-4-5 surge requirements.
Its 215 pF typical capacitance at 0 V bias supports USB 2.0 and audio line speeds without signal integrity degradation, while 300 nA max reverse leakage at VRWM = 3.3 V ensures minimal impact on low-power sensor or SIM card detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous operating voltage before conduction begins; matches 3.3 V logic rail systems. |
| Clamping Voltage | 12 V at IPP = 20 A - Limits transient voltage seen by downstream ICs during IEC 61000-4-5 surge events. |
| ESD Withstand | ±30 kV contact discharge - Complies with IEC 61000-4-2 level 4, eliminating need for external ESD test margining. |
| Diode Capacitance | 215 pF typical at 1 MHz, 0 V - Enables use on USB D+/D−, SDIO, or audio codec lines without bandwidth loss. |
| Peak Pulse Power | 200 W per diode - Sustains 8/20 µs surges up to 20 A without degradation, supporting industrial-grade robustness. |
| Reverse Leakage | 300 nA typical at VRWM = 3.3 V - Preserves battery life in always-on SIM detection or touch controller bias networks. |
| Breakdown Voltage | 5.6 V typical at IR = 1 mA - Ensures reliable turn-on well above 3.3 V rail while avoiding false triggering. |
Pinout & Package
SOT457 (SC-74) is a 6-lead surface-mount plastic package measuring 3.1 × 1.7 × 1.3 mm, optimized for automated placement and reflow soldering on dense PCBs.

|---|---|---|
| 1 | Cathode 1 | Protected signal line #1; connects to I/O 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. |
| 3 | Cathode 2 | Protected signal line #2; electrically isolated from other cathodes for independent line protection. |
| 4 | Cathode 3 | Protected signal line #3; enables compact multi-line protection without discrete diode arrays. |
| 5 | Cathode 4 | Protected signal line #4; supports bidirectional data lanes when paired with complementary devices. |
| 6 | Cathode 5 | Protected signal line #5; completes full five-line coverage for interfaces like microSD or camera parallel bus. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | 6-pin SOT23-6, 6.1 V VRWM, 12.5 V clamping at 12 A, 100 pF capacitance | Better suited for 5 V systems; lower capacitance but reduced surge rating (12 A vs. 20 A) | Select when protecting 5 V UART or SPI lines where lower capacitance outweighs surge headroom needs. |
| TPD4E001DPYR | 6-pin X2SON, 5.5 V VRWM, 14 V clamping at 4 A, 12 pF capacitance | Optimized for high-speed USB 3.0/PCIe; insufficient for 20 A IEC 61000-4-5 surge | Prefer for >1 GHz differential pairs; not recommended for SIM or SDIO where 20 A surge immunity is required. |
Compared with ESDA6V1SC6 and TPD4E001DPYR, PESD3V3S5UD,115 uniquely balances 3.3 V compatibility, 20 A surge capability, and five-line integration-making it optimal for space-constrained 3.3 V portable interfaces where both ESD and surge robustness are mandatory.

FAQ
What is the maximum peak pulse current rating for PESD3V3S5UD,115?
The device is rated for 20 A peak pulse current (IPP) under IEC 61000-4-5 8/20 µs waveform conditions, verified per Table 5 of the Nexperia datasheet Rev. 02. This rating applies per diode (Pins 1, 3–6 to Pin 2) and defines its ability to safely divert surge energy without parametric shift or failure.
Can PESD3V3S5UD,115 be used for bidirectional signal lines?
No-it is a unidirectional ESD array with cathodes on Pins 1, 3–6 and a common anode on Pin 2, suitable only for signals referenced to ground with positive-going transients. For bidirectional lines like USB D+/D−, two devices or a dedicated bidirectional array (e.g., PESD5V0S5UD) must be used.
How does the 215 pF diode capacitance affect high-speed signal integrity?
At 215 pF typical (measured at 1 MHz, 0 V), the device introduces minimal loading on 3.3 V digital lines up to 480 Mbps (USB 2.0 full-speed). Layout best practices-placing it within 3 mm of the connector and using short, direct traces-ensure rise time degradation remains below 10%, preserving eye diagram margins.
Is PESD3V3S5UD,115 compliant with RoHS and REACH?
Yes-Nexperia confirms PESD3V3S5UD,115 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin termination and halogen-free molding compound, as documented in the official product change notice PCN-2017-001 and material declarations on nexperia.com.
