Product details
Overview
PESD24VS2UAT from Nexperia is a unidirectional double ESD protection diode in common-cathode SOT23 configuration, designed to protect two data lines against IEC 61000-4-2 level 4 ESD (23 kV contact), IEC 61000-4-5 surge (3 A, 8/20 µs), with 24 V reverse standoff voltage, 23 pF typical capacitance, and ultra-low 1 nA leakage current - deployed in USB, HDMI, and audio interface protection.
For engineers reviewing the PESD24VS2UAT datasheet, PESD24VS2UAT pinout, PESD24VS2UAT application, or PESD24VS2UAT equivalent, key selection criteria include clamping voltage under 70 V at 3 A surge, common-cathode dual-anode topology for ground-referenced signal lines, low capacitance for high-speed data integrity, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a dual-diode common-cathode architecture where pins 1 and 2 serve as independent anodes tied to separate protected lines, while pin 3 functions as the shared cathode connected to system ground. It operates exclusively in unidirectional mode, clamping only negative transients relative to ground.
Its transient response is defined by IEC 61000-4-2 (23 kV contact discharge) and IEC 61000-4-5 (3 A, 8/20 µs surge), with clamping voltage specified at ≤70 V and differential resistance ≤300 Ω - enabling robust protection without signal distortion on low-voltage, high-bandwidth interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - maximum continuous operating voltage before conduction; ensures no interference with 24 V nominal signal rails. |
| Clamping Voltage | ≤70 V at 3 A (8/20 µs) - limits transient voltage seen by downstream ICs during surge events. |
| Diode Capacitance | 23 pF typical at 1 MHz, 0 V - preserves signal integrity on USB 2.0 and audio lines up to ~100 MHz. |
| ESD Rating | 23 kV contact per IEC 61000-4-2 level 4 - exceeds industrial immunity requirements for handheld port interfaces. |
| Peak Pulse Power | 160 W at 8/20 µs - sustains short-duration surges without thermal failure in compact SOT23 package. |
| Reverse Leakage | 1 nA at 24 V - negligible DC loading on sensitive analog or logic inputs. |
Pinout & Package
SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch); thermally optimized for reflow soldering per JEDEC MS-012 (TO-236AB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Connects to first protected data line (e.g., USB D+); conducts only when line voltage falls below ground. |
| 2 | Anode of Diode 2 | Connects to second protected data line (e.g., USB D−); independent clamping path, same cathode reference. |
| 3 | Common Cathode | Single ground connection point for both diodes; minimizes PCB trace inductance and improves simultaneous clamping symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual-anode topology | Enables coordinated low-inductance grounding for two lines sharing one return path - critical for differential pair protection. |
| 23 pF typical capacitance | Preserves rise time and eye diagram integrity on 480 Mbps USB 2.0 signals without added jitter or attenuation. |
| 1 nA reverse leakage | Prevents DC bias shift or false triggering in high-impedance sensor or audio amplifier inputs. |
| 23 kV IEC 61000-4-2 contact ESD rating | Meets or exceeds EN 61000-6-2 immunity requirements for Class A/B industrial equipment interfaces. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Channel Protection |
|---|---|
Use Scenario: Protecting USB D+ and D− lines on host controllers and peripheral devices against user-handling ESD events. IC Role / Device Role: Unidirectional clamping diode array placed within 2 mm of USB connector to minimize transient loop area. Use Value: Maintains 480 Mbps data rate integrity while limiting transient overshoot to ≤70 V during 23 kV contact discharge. | Use Scenario: Safeguarding HDMI Display Data Channel (DDC) lines (SCL/SDA) from ESD during cable insertion/removal. IC Role / Device Role: Dual-line ESD suppressor referenced to system ground, compatible with 3.3 V I²C logic levels. Use Value: 23 pF capacitance avoids timing violations on 100 kHz DDC clock, while 1 nA leakage prevents pull-up resistor loading. |
| Audio Line Input Protection | Industrial RS-485 Transceiver I/O |
Use Scenario: Shielding line-in or microphone inputs on consumer audio codecs from electrostatic discharge during jack insertion. IC Role / Device Role: Ground-referenced bidirectional-capable protection via unidirectional diodes configured for negative-only clamping. Use Value: 24 V VRWM accommodates ±12 V audio signal swings; 70 V clamping prevents op-amp input stage damage. | Use Scenario: Protecting RS-485 receiver inputs (A/B) in factory automation nodes exposed to cable-induced surges. IC Role / Device Role: Dual-line transient suppressor mounted at connector entry point, leveraging common-cathode layout for balanced clamping. Use Value: 160 W peak pulse power handles 3 A IEC 61000-4-5 surges without degradation across 150 °C junction temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP2114 | Higher 30 pF capacitance; 12 V VRWM; 30 kV ESD rating | Better suited for lower-voltage logic (e.g., 3.3 V I/O), less ideal for 24 V signal rails | Select when ESD margin >30 kV is required and capacitance tolerance allows ≥30 pF. |
| Vishay VEML6030X01 | Photodiode + integrated ESD clamp; 5.5 V VRWM; not a discrete dual-diode | Designed for ambient light sensing with built-in protection - not a drop-in replacement | Only applicable in optical sensor subsystems requiring co-packaged photodiode and ESD function. |
Compared with NUP2114 and VEML6030X01, PESD24VS2UAT uniquely balances 24 V standoff, 23 pF capacitance, and SOT23 footprint for general-purpose dual-line protection - making it optimal for USB, HDMI DDC, and industrial serial interfaces where voltage headroom and signal fidelity are jointly critical.

FAQ
What is the maximum operating temperature for PESD24VS2UAT?
The PESD24VS2UAT supports a junction temperature range up to 150 °C and an ambient operating temperature from −65 °C to +150 °C. Its thermal performance is validated per IEC 60134 limiting values, with derated peak pulse power above 25 °C - as shown in Figure 4 of the datasheet - ensuring reliability in enclosed industrial enclosures or automotive under-hood proximity.
Can PESD24VS2UAT protect bidirectional signal lines like RS-485?
Yes - though unidirectional in structure, PESD24VS2UAT protects RS-485 A/B lines when used with proper grounding: each anode connects to one line, and the common cathode ties to clean system ground. It clamps negative transients on both lines simultaneously, and positive transients are handled by the receiver's internal protection or external TVS if needed.
Is the 23 kV ESD rating applicable to both pins 1 and 2 independently?
Yes - the 23 kV IEC 61000-4-2 contact discharge rating applies individually to each anode (pin 1 and pin 2) referenced to the common cathode (pin 3). Testing per section 8 confirms this value is maintained whether stressing one or both anodes, provided the cathode remains grounded during evaluation.
How does the 23 pF capacitance affect USB 2.0 signal integrity?
At 23 pF typical, the PESD24VS2UAT adds minimal capacitive loading to USB 2.0 differential pairs - preserving signal rise time (<1 ns degradation), maintaining eye opening at 480 Mbps, and avoiding measurable jitter or bit error rate increase when placed within 3 mm of the connector per layout guidelines in section 10 of the datasheet.
