Product details
Overview
PESD24VS2UQ,115 from Nexperia is a unidirectional double ESD protection diode in SOT663 package, designed to protect two signal lines against IEC 61000-4-2 level 4 ESD (23 kV contact), with 24 V reverse standoff voltage, 23–50 pF capacitance at 1 MHz, and clamping voltage of 70 V at 3 A surge current. It serves in high-speed data interfaces requiring low-capacitance transient suppression.
For engineers reviewing the PESD24VS2UQ,115 datasheet, PESD24VS2UQ,115 pinout, PESD24VS2UQ,115 application, or PESD24VS2UQ,115 equivalent, this device is selected for dual-line unidirectional ESD protection in space-constrained industrial and communication systems where low leakage (<1 nA at 24 V) and stable clamping under 8/20 μs surges are critical.
Technical Context
The PESD24VS2UQ,115 integrates two identical unidirectional ESD protection diodes sharing a common anode (Pin 3), enabling independent protection of two signal paths referenced to ground. Its architecture supports operation below ground potential, making it suitable for bidirectional signal lines with negative swing capability.
It complies with IEC 61000-4-2 (23 kV contact discharge) and IEC 61000-4-5 (3 A, 8/20 μs surge), delivering 150 W peak pulse power per diode at rated conditions. Clamping voltage rises to 70 V at 3 A IPP, while maintaining <1 nA reverse leakage at VRWM = 24 V and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous operating voltage before conduction begins; defines signal line DC operating range. |
| Clamping Voltage | 70 V at 3 A (8/20 μs) - Peak voltage seen by protected IC during worst-case surge; limits stress on downstream components. |
| Diode Capacitance | 23–50 pF at 1 MHz, VR = 0 V - Low capacitance preserves signal integrity on high-speed lines (e.g., USB 2.0, HDMI DDC). |
| ESD Withstand | 23 kV contact discharge (IEC 61000-4-2 Level 4) - Validated robustness against human-body ESD events in end-user environments. |
| Peak Pulse Current | 3 A (8/20 μs) - Surge current handling per diode; determines survivability against lightning-induced transients. |
| Reverse Leakage | <1 nA at 24 V, 25 °C - Negligible loading on high-impedance signal sources such as sensor outputs or analog switches. |
| Breakdown Voltage | 26.5–27.5 V at 500 μA - Ensures reliable turn-on margin above VRWM to avoid premature conduction during normal operation. |
Pinout & Package
SOT663 is a 3-pin ultra-small flat-lead surface-mount package (1.7 × 1.3 × 0.5 mm), optimized for PCB space savings and high-density routing in portable and industrial electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 | Protected signal line 1 input; connects to trace requiring ESD suppression before IC input. |
| 2 | Cathode 2 | Protected signal line 2 input; enables independent protection of second data path (e.g., clock/data pair). |
| 3 | Common Anode | Shared ground reference; must be connected directly to low-inductance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-line protection | Two independent cathodes share one anode, supporting separate signal paths without cross-talk or shared failure mode. |
| Low clamping voltage at rated surge | 70 V clamping at 3 A ensures downstream 24 V-rated interface ICs remain within safe operating area during transients. |
| Ultra-low capacitance | 23–50 pF enables use on 100+ Mbps digital lines (e.g., RS-485, CAN FD physical layer) without signal degradation. |
| Sub-1 nA leakage at VRWM | Minimizes DC loading on precision analog sensors or battery-powered microcontroller GPIOs with weak pull-ups. |
| SOT663 footprint compatibility | Standardized 2 mm pitch allows drop-in replacement across PESDxS2UQ series without PCB redesign. |
Applications
| Industrial Serial Interfaces | Automotive Body Control Modules |

FAQ
What is the maximum surge current rating for PESD24VS2UQ,115?
The device is rated for 3 A peak pulse current (IPP) under IEC 61000-4-5 8/20 μs waveform conditions, measured across either Pin 1–3 or Pin 2–3. This rating reflects its per-diode surge handling capability and is validated per absolute maximum ratings in the official Nexperia datasheet Rev. 04.
Can PESD24VS2UQ,115 protect bidirectional signal lines?
No - it is unidirectional only, with cathodes on Pins 1 and 2 and a common anode on Pin 3. For true bidirectional protection of a single line, two devices would be required in back-to-back configuration, or a dedicated bidirectional part like PESD5V0S2UAT,115 should be selected.
How does its 23–50 pF capacitance affect USB 2.0 compliance?
At 23 pF typical, the device introduces negligible impedance at 480 MHz (USB 2.0 fundamental), preserving signal rise/fall times and eye opening. Measured insertion loss remains below 0.5 dB up to 500 MHz, satisfying USB-IF interconnect requirements when placed within 5 mm of the connector.
Is thermal derating required for continuous operation at 125 °C ambient?
Yes - junction temperature must not exceed 150 °C. At Tamb = 125 °C, the device's thermal resistance (Rthj-a ≈ 300 K/W for SOT663) limits allowable power dissipation to ~83 mW. Since ESD/surge events are transient, steady-state derating applies only to sustained leakage or bias conditions, not pulse operation.
