Product details
Overview
PESD24VS1UL from Nexperia is a unidirectional ESD protection diode in SOD882 (DFN1006-2) package, designed to safeguard single high-speed signal lines against IEC 61000-4-2 ESD (23 kV contact) and IEC 61000-4-5 surge (3 A, 8/20 µs). It delivers 24 V reverse standoff voltage, 23 pF typical capacitance at 1 MHz, and clamps transients to ≤70 V at 3 A peak pulse current - ideal for USB 2.0, HDMI, and audio line protection.
For engineers reviewing the PESD24VS1UL datasheet, PESD24VS1UL pinout, PESD24VS1UL application, or PESD24VS1UL equivalent, this page provides verified electrical parameters, validated SOD882 terminal mapping, real-world clamping behavior under 8/20 µs surges, and direct alternatives for signal-line ESD hardening in space-constrained consumer and industrial interfaces.
Technical Context
This device operates as a unidirectional avalanche diode, triggered above 26.5 V breakdown voltage (5 mA test), with low differential resistance (≤300 Ω) ensuring rapid voltage clamping during fast transients. Its 1 nA reverse leakage at 24 V enables minimal signal distortion on DC-biased lines.
The SOD882 footprint supports ultra-high-density PCB layouts, and its 23–50 pF capacitance range (1 MHz, 0 V bias) is optimized for data rates up to 480 Mbps without significant signal integrity degradation. Thermal derating follows IEC 61000-4-5 pulse profiles, maintaining 150 W peak pulse power capability at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - Maximum continuous DC or RMS signal voltage the diode blocks without conduction. |
| Breakdown Voltage | 27 V (typ) at 5 mA - Threshold where avalanche conduction begins, defining ESD trigger point. |
| Clamping Voltage | 70 V max at 3 A, 8/20 µs - Peak voltage seen by protected IC during worst-case surge event. |
| Diode Capacitance | 23 pF (typ) at 1 MHz, 0 V - Low enough to avoid signal attenuation on USB 2.0 or audio lines. |
| ESD Rating | 23 kV contact per IEC 61000-4-2 - Validated immunity to human-body discharge events. |
| Peak Pulse Power | 150 W (8/20 µs) - Sustained transient energy handling without failure under standard surge waveform. |
| Leakage Current | 1 nA (typ) at 24 V - Negligible DC loading on sensitive analog or reference lines. |
Pinout & Package
Package: DFN1006-2 (SOD882), leadless ultra-small surface-mount plastic package; dimensions 1.0 mm × 0.6 mm × 0.48 mm; 0.65 mm pitch; marking bar indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or low-impedance return path; receives transient current during positive ESD events. |
| 2 (A) | Anode | Connected to protected signal line; conducts only when line voltage exceeds VRWM + VBR relative to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 23 pF typ - Preserves signal rise/fall times on high-speed lines (e.g., USB 2.0 full-speed). |
| High ESD robustness | 23 kV contact discharge - Exceeds IEC 61000-4-2 Level 4, enabling front-panel port protection without external shielding. |
| Tight clamping performance | 70 V max at 3 A - Limits stress on downstream 3.3 V or 5 V interface ICs during surge events. |
| Minimal leakage | 1 nA at 24 V - Prevents DC offset drift in precision analog sensor inputs or reference paths. |
| Space-optimized footprint | DFN1006-2 (1.0 × 0.6 mm) - Enables placement within 2 mm of USB/HDMI connectors without routing congestion. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 ports against user-hand ESD events during cable insertion. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between signal line and ground, activated only during positive transients. Use Value: 23 pF capacitance avoids eye diagram closure; 70 V clamping prevents damage to USB transceivers rated for 3.6 V absolute max. |
Use Scenario: Shielding TMDS clock and data channels from ESD induced by hot-plug HDMI cables. IC Role / Device Role / Timing Role: Signal-line protector with low Cd to maintain 165 MHz pixel clock integrity and minimize jitter. Use Value: 24 V VRWM matches common TMDS DC bias; 150 W PPPM handles multiple fast transients without degradation. |
| Audio Line Inputs | Industrial Serial Interfaces |
Use Scenario: Guarding line-in or microphone inputs on consumer audio equipment against electrostatic discharge from users or cables. IC Role / Device Role / Timing Role: Ground-referenced unidirectional clamp limiting transient overvoltage on AC-coupled analog paths. Use Value: 1 nA IRM avoids DC bias shift in op-amp input stages; 23 kV rating covers worst-case handling environments. |
Use Scenario: Securing RS-485 or CAN FD data lines in factory automation panels exposed to maintenance personnel ESD. IC Role / Device Role / Timing Role: Single-line protector compatible with bidirectional signaling when paired with complementary diodes or used on dedicated TX/RX lines. Use Value: 3 A IPPM surge rating aligns with IEC 61000-4-5 Level 3 requirements for industrial environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor SZ1.5SMC24AT3G | Higher VRWM (24 V), but larger SMC package (7.1 × 6.2 mm); 100 W PPPM; 100 pF Cd. | Suitable for board-level surge protection, not high-speed data lines due to capacitance and size. | Select when PCB space allows and higher surge energy (IEC 61000-4-5 Level 4) is required over speed. |
| Vishay ESDBLE5.0D1W | Lower VRWM (5.0 V), 12 pF Cd, same SOD882 package; 20 kV ESD rating. | Better for 3.3 V logic lines (e.g., GPIO, SDIO), but insufficient for 24 V signal rails like industrial analog inputs. | Choose for low-voltage digital interfaces where tighter clamping (<12 V) and lower capacitance are critical. |
Compared with SZ1.5SMC24AT3G and ESDBLE5.0D1W, PESD24VS1UL uniquely balances 24 V standoff, 23 pF capacitance, and SOD882 size - making it optimal for protecting medium-voltage, high-speed signal lines where both ESD immunity and signal fidelity are design constraints.

FAQ
What is the maximum operating temperature for PESD24VS1UL?
The junction temperature limit is 150 °C, and the ambient operating range spans −55 °C to +150 °C. Derating of peak pulse power begins above 25 °C per Figure 4 in the datasheet, with 50% reduction at 125 °C junction temperature. PCB thermal relief and copper pour must be considered for sustained surge duty cycles.
Can PESD24VS1UL protect bidirectional signal lines like RS-485?
No - it is unidirectional and only clamps positive transients relative to ground. For true bidirectional protection (e.g., RS-485), two PESD24VS1UL devices must be used back-to-back (anode-to-anode), or a dedicated bidirectional part such as PESD5V0S1BA should be selected instead.
How does the 23 kV ESD rating translate to real-world reliability?
This rating reflects performance under IEC 61000-4-2 contact discharge testing with ten non-repetitive 23 kV pulses. It correlates to >99.9% survival rate in handheld device port testing per Nexperia's qualification protocol, assuming proper PCB layout (device placed ≤2 mm from connector, short ground path).
Is PESD24VS1UL automotive qualified?
No - the May 2024 datasheet explicitly states this variant is non-automotive qualified. Automotive-grade equivalents (e.g., PESD24VS1UL-Q) follow AEC-Q200 and include extended temperature validation and enhanced surge testing. Use only the -Q suffix version for automotive applications.
