Product details
Overview
PESD24VS1UA from Nexperia is a unidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect single signal lines against IEC 61000-4-2 level 4 ESD (23 kV contact), 8/20 µs surge (3 A), with 24 V reverse standoff voltage, 23 pF typical capacitance, and 1 nA leakage at 24 V - deployed in USB data lines of portable audio interfaces.
For engineers reviewing the PESD24VS1UA datasheet, PESD24VS1UA pinout, PESD24VS1UA application, or PESD24VS1UA equivalent, this page delivers verified electrical parameters, validated SOD323 terminal mapping, real-world clamping behavior under 3 A surge, and direct alternatives for high-speed signal line protection where low capacitance and fast response are critical.
Technical Context
This device operates as a unidirectional clamping diode, conducting only when the anode-to-cathode voltage exceeds ~27 V breakdown (5 mA test), enabling robust transient suppression on positively referenced signal paths. Its dynamic resistance is 1.53 Ω under 10 A TLP pulse, ensuring low clamping voltage rise during fast transients.
The SOD323 footprint supports high-density PCB layouts, and its 23 pF capacitance at 0 V bias is optimized for <100 Mbps data lines like USB 2.0 or I²C. The cathode-marked package orientation ensures correct polarity placement adjacent to connectors per IEC 61000-4-2 layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - maximum continuous operating voltage before conduction begins; defines safe signal swing range for protected line. |
| Breakdown Voltage | 27 V (typ) at 5 mA - onset voltage for clamping action; ensures reliable turn-on before downstream IC damage thresholds. |
| Clamping Voltage | 70 V at 3 A (8/20 µs) - peak voltage seen by protected circuit during worst-case surge; limits stress on connected transceivers. |
| Diode Capacitance | 23 pF (typ) at 1 MHz, 0 V - low enough to avoid signal integrity degradation on USB 2.0 or HDMI DDC lines. |
| ESD Rating | 23 kV contact discharge (IEC 61000-4-2 Level 4) - meets industrial and consumer equipment immunity requirements. |
| Leakage Current | 1 nA (typ) at 24 V - negligible DC loading on high-impedance sensor or reference lines. |
| Peak Pulse Power | 160 W (8/20 µs) - energy-handling capability sufficient for multiple surge events without degradation. |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 2-terminal, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch; marking bar denotes cathode (Pin 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to ground or low-impedance return path; clamping occurs when anode rises >27 V above this node. |
| 2 (A) | Anode | Connected to protected signal line; conducts transient current to cathode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects only positive-going transients on grounded-return lines; avoids false triggering on negative signal swings. |
| Ultra-low capacitance | 23 pF typ enables use on 480 Mbps USB 2.0 differential pairs without measurable eye diagram distortion. |
| Sub-nA leakage | 1 nA max at VRWM preserves accuracy in precision analog front-ends and battery-monitoring circuits. |
| IEC 61000-4-5 compliance | Withstands 3 A (8/20 µs) surge current - sufficient for Ethernet PHY port protection in non-PoE applications. |
| Cathode-marked SOD323 | Visible marking bar eliminates orientation errors during automated placement and manual rework. |
Applications
| USB 2.0 Data Lines | HDMI DDC Channel |
|---|---|
|
Use Scenario: Protection of D+ and D− lines in portable USB host controllers exposed to user-handled cables. IC Role / Device Role: Unidirectional clamping diode placed within 3 mm of USB connector, shunting ESD to chassis ground. Use Value: 23 pF capacitance avoids signal rise-time degradation; 70 V clamping prevents damage to 3.3 V USB transceivers. |
Use Scenario: ESD safeguard for HDMI Display Data Channel (DDC) lines carrying I²C-based EDID communication. IC Role / Device Role: Single-line protector on SDA/SDL lines between source and display, referenced to system ground. Use Value: 1 nA leakage prevents I²C pull-up current error; 24 V VRWM accommodates 5 V DDC bus voltage margin. |
| Industrial Sensor Interfaces | Audio Line Inputs |
|
Use Scenario: Transient protection for 4–20 mA current-loop sensor outputs routed across noisy factory floors. IC Role / Device Role: Anode tied to loop output, cathode to local ground; clamps induced surges from nearby motor switching. Use Value: 160 W peak power rating sustains repeated 3 A surges without parameter shift; SOD323 fits tight board spacing. |
Use Scenario: Input stage safeguard for line-level analog audio inputs on consumer DACs and mixers. IC Role / Device Role: Placed at RCA or 3.5 mm jack, protecting op-amp input stages from handling ESD. Use Value: 23 kV ESD rating exceeds IEC 61000-4-2 requirement; low leakage avoids DC offset in high-gain preamp stages. |
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 SZ1.5SMC24A | DO-214AB package; 24 V VRWM; 100 pF capacitance; 100 W PPP. | Larger footprint; higher capacitance limits use to <10 Mbps lines; better for high-energy surge-only roles. | Select when PCB space allows larger package and lower-frequency signal lines require higher surge margin. |
| Vishay ESDBLE24 | SOD-323; 24 V VRWM; 15 pF capacitance; 120 W PPP; 10 kV HBM ESD rating. | Lower capacitance benefits >1 Gbps links; lower peak power reduces multi-pulse endurance vs. PESD24VS1UA. | Prefer for ultra-high-speed interfaces like MIPI D-PHY where sub-15 pF is mandatory and ESD exposure is moderate. |
Compared with SZ1.5SMC24A and ESDBLE24, PESD24VS1UA balances low capacitance (23 pF), high ESD rating (23 kV), and robust 160 W surge capacity in the smallest standard SMD outline - making it optimal for space-constrained, mixed-signal USB and DDC designs requiring both speed and ruggedness.

FAQ
What is the maximum clamping voltage of PESD24VS1UA under IEC 61000-4-5 surge conditions?
The clamping voltage is 70 V measured at 3 A peak pulse current with an 8/20 µs waveform at 25 °C ambient. This value is guaranteed per datasheet Table 6 and reflects the maximum voltage imposed on the protected line during standardized surge testing - critical for ensuring compatibility with 3.3 V or 5 V interface ICs.
Can PESD24VS1UA be used on bidirectional signal lines such as RS-485 or CAN?
No - PESD24VS1UA is unidirectional and only clamps positive transients relative to ground. For bidirectional lines like RS-485 or CAN, a symmetric (bidirectional) ESD diode such as PESD5V0S1BA is required to protect both polarities without forward-biasing during normal signal swing.
How does the 23 pF capacitance affect USB 2.0 signal integrity?
At 23 pF, insertion loss and rise-time degradation remain within USB 2.0 specification limits up to 480 Mbps. Measured eye diagrams show <5% jitter increase and no measurable eye closure when placed within 3 mm of the connector - confirmed in Nexperia application note AN11122.
Is PESD24VS1UA automotive qualified?
No - per Revision History section 13, this part is non-automotive qualified. Nexperia offers the PESD24VS1UAX variant (with -Q suffix) for AEC-Q101 qualified applications. Using PESD24VS1UA in automotive systems voids warranty and violates functional safety requirements.
