Product details
Overview
PESD15VS4UD,115 from Nexperia is a quadruple unidirectional ESD protection diode array in SOT457 (SC-74) package, designed to protect four signal lines against electrostatic discharge up to 30 kV (IEC 61000-4-2 level 4), with 15 V reverse standoff voltage, 60–90 pF diode capacitance at 1 MHz, and clamping voltage of 22 V at 1 A / 33 V at 6 A peak pulse current. It is used in portable electronics, SIM card interfaces, and high-speed data lines where low capacitance and robust transient suppression are required.
For engineers reviewing the PESD15VS4UD,115 datasheet, PESD15VS4UD,115 pinout, PESD15VS4UD,115 application, or PESD15VS4UD,115 equivalent, key selection criteria include reverse standoff voltage (15 V), clamping performance under 6 A surge, ultra-low leakage (<15 nA at VRWM), IEC 61000-4-2/4-5 compliance, and SOT457 footprint compatibility for space-constrained PCB layouts.
Technical Context
The PESD15VS4UD,115 integrates four independent unidirectional ESD protection diodes sharing two common anode terminals (pins 2 and 5), enabling compact protection of four separate signal paths. Its architecture supports both above-ground and below-ground signal polarities without requiring external biasing.
Each diode exhibits a breakdown voltage of 15.5–20.5 V at 1 mA, clamps transients to ≤33 V at 6 A (8/20 µs), and delivers 200 W peak pulse power per line. The device meets IEC 61000-4-2 level 4 (±30 kV contact discharge) and IEC 61000-4-5 (surge up to 6 A), with junction temperature rated to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 15 V - Maximum continuous operating voltage before conduction; ensures no interference with 15 V logic or interface signals. |
| Clamping Voltage (VCL) | 22 V at IPP = 1 A; 33 V at IPP = 6 A - Limits transient voltage seen by downstream ICs during ESD/surge events. |
| Diode Capacitance (Cd) | 60–90 pF at 1 MHz, VR = 0 V - Low enough for USB 2.0, SIM card, and audio data lines without signal integrity degradation. |
| Peak Pulse Current (IPP) | 6 A (8/20 µs) - Sustains IEC 61000-4-5 surge stress without failure; lower than 20 A variants due to higher VRWM. |
| ESD Withstand (VESD) | 30 kV contact discharge (IEC 61000-4-2 level 4) - Protects end-user accessible ports against real-world human-body ESD events. |
| Reverse Leakage (IRM) | ≤15 nA at VRWM = 15 V - Minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| Package | SOT457 (SC-74) - 6-pin surface-mount package (3.0 × 1.7 mm) with standardized footprint for automated assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDA6V1SC6 | Lower VRWM (6.1 V), higher capacitance (120 pF), same SOT457 package and 30 kV ESD rating. | Better suited for 5 V logic interfaces (e.g., HDMI CEC, I²C), not recommended for 15 V signal lines. | Select ESDA6V1SC6 only if protecting sub-7 V systems; PESD15VS4UD,115 is mandatory for 12–15 V rail compatibility. |
| TPD4E001DPYR | 10 V VRWM, 12 pF typical capacitance, 30 kV ESD, 4-channel unidirectional, X2SON package (1.0 × 1.0 mm). | Superior for ultra-high-speed interfaces (USB 3.0, MIPI) due to ultra-low capacitance; smaller footprint but lower surge rating (4 A). | Choose TPD4E001DPYR for space-critical, high-frequency designs; retain PESD15VS4UD,115 when 15 V standoff or 6 A surge handling is required. |
Compared with ESDA6V1SC6 and TPD4E001DPYR, the PESD15VS4UD,115 uniquely balances 15 V operating margin, 6 A surge capability, and moderate capacitance-making it optimal for industrial sensors, SIM slots, and legacy USB 2.0 where voltage headroom and ruggedness outweigh ultra-low-C needs.

FAQ
What is the maximum continuous reverse voltage the PESD15VS4UD,115 can withstand?
The PESD15VS4UD,115 has a reverse standoff voltage (VRWM) of 15 V, meaning it blocks up to 15 V DC or steady-state AC signals without conducting. This rating ensures compatibility with 12–15 V interface rails such as industrial sensor outputs and SIM card VCC lines, while maintaining low leakage below 15 nA.
Does the PESD15VS4UD,115 meet IEC 61000-4-5 surge immunity standards?
Yes, the PESD15VS4UD,115 complies with IEC 61000-4-5 for surge immunity, sustaining up to 6 A peak pulse current (8/20 µs waveform). Its 33 V clamping voltage at 6 A ensures protected circuits remain within safe operating limits during lightning-induced or inductive-switching transients.
How many signal lines can the PESD15VS4UD,115 protect simultaneously?
The PESD15VS4UD,115 protects up to four unidirectional signal lines using its six-pin SOT457 configuration: pins 1, 3, 4, and 6 serve as individual cathodes, while pins 2 and 5 function as dual common anodes-enabling flexible grounding schemes for noise-sensitive applications.
What is the diode capacitance of the PESD15VS4UD,115 at 1 MHz?
The PESD15VS4UD,115 exhibits a diode capacitance of 60–90 pF at 1 MHz and 0 V reverse bias. This value is measured per diode and supports reliable operation on USB 2.0, audio, and SIM card interfaces without degrading signal rise/fall times or causing impedance mismatch.
Is the PESD15VS4UD,115 suitable for bidirectional signal protection?
No-the PESD15VS4UD,115 is a unidirectional ESD protection array. For bidirectional lines (e.g., USB D+, D−), it must be used with external biasing or paired with complementary devices.
