Product details
Overview
PESD24VS1UL from Nexperia is a unidirectional ESD protection diode in a DFN1006-2 (SOD882) package, designed to safeguard single high-speed signal lines against electrostatic discharge and surge transients. It delivers 23 kV IEC 61000-4-2 contact ESD protection, clamps at ≤70 V under 3 A 8/20 µs surge, and exhibits ultra-low 1 nA reverse leakage at 24 V standoff voltage - deployed in USB 2.0, HDMI, and audio line interfaces.
For engineers reviewing the PESD24VS1UL datasheet, PESD24VS1UL pinout, PESD24VS1UL application, or PESD24VS1UL equivalent, key selection criteria include clamping voltage under 3 A surge, sub-50 pF capacitance at 1 MHz, unidirectional polarity handling, and compatibility with space-constrained 0.65 mm pitch PCB layouts.
Technical Context
This device operates as a unidirectional transient voltage suppressor, leveraging silicon avalanche breakdown to clamp fast-rising ESD pulses (IEC 61000-4-2, 0.6–1 ns rise time) while maintaining low dynamic impedance (<300 Ω) and minimal capacitive loading on protected lines.
Its 24 V reverse standoff voltage ensures compatibility with 3.3 V and 5 V logic systems, and its 150 W peak pulse power rating (8/20 µs) supports robust surge immunity per IEC 61000-4-5 up to 3 A - validated across ambient temperatures from −55 °C to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 24 V - defines maximum continuous operating voltage before conduction begins; matches 3.3 V/5 V I/O rails without leakage-induced signal distortion |
| Clamping Voltage | ≤70 V at 3 A (8/20 µs) - limits transient overvoltage seen by downstream ICs during surge events |
| Diode Capacitance | 23–50 pF at 1 MHz, 0 V - enables use on high-speed data lines (e.g., USB 2.0, audio DAC outputs) without signal integrity degradation |
| ESD Rating | 23 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial and consumer immunity requirements for handheld and peripheral interfaces |
| Peak Pulse Power | 150 W (8/20 µs) - sustains short-duration surges without thermal runaway or parametric shift |
| Reverse Leakage | 1 nA typical at 24 V - prevents DC loading or bias drift in precision analog or low-power sensor signal paths |
Pinout & Package
DFN1006-2 (SOD882) is a leadless, ultra-small surface-mount plastic package measuring 1.0 mm × 0.6 mm × 0.48 mm with 0.65 mm terminal pitch. The marking bar identifies Pin 1 (cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or low-side reference; conducts during positive transients on the protected line (anode side) |
| 2 (A) | Anode | Connected to the signal line requiring protection; blocks DC in normal operation, avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 23 pF typical - preserves signal edge rate and bandwidth on 480 Mbps USB 2.0 and 216 MHz HDMI TMDS lines |
| High ESD immunity | 23 kV contact discharge - eliminates need for secondary board-level shielding in portable peripherals |
| Tight clamping performance | 70 V max at 3 A surge - protects 3.3 V I/O pins of microcontrollers and PHYs without violating absolute maximum ratings |
| Thermal robustness | 150 °C max junction temperature - supports reflow soldering and sustained operation in enclosed industrial enclosures |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protection of D+ and D− differential pairs in USB 2.0 host/device connectors exposed to user-handling ESD. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed between each data line and ground, responding within <1 ns to divert ESD current away from USB transceiver I/O cells. Use Value: Prevents latch-up or gate oxide damage in USB PHYs while adding <50 pF load - no impact on eye diagram integrity at 480 Mbps. | Use Scenario: Transient suppression on HDMI TMDS clock and data channels in set-top boxes and AV receivers. IC Role / Device Role / Timing Role: Ground-referenced unidirectional ESD clamp on each TMDS+ line, leveraging low capacitance to avoid skew or jitter accumulation. Use Value: Maintains HDMI compliance for rise/fall times (200–800 ps) and differential impedance (100 Ω) while surviving repeated ±8 kV contact discharges. |
| Audio Line Outputs | Industrial Serial Interfaces |
Use Scenario: ESD hardening of line-out or headphone amplifier outputs in portable audio players and docking stations. IC Role / Device Role / Timing Role: Cathode-to-ground configuration protecting AC-coupled analog output paths where signal swings are unidirectional relative to ground. Use Value: Adds negligible noise (1 nA leakage) and avoids DC offset shift, preserving THD+N <0.01% in 24-bit audio paths. | Use Scenario: Surge protection for RS-232 or RS-485 driver/receiver pins in factory automation controllers and PLC I/O modules. IC Role / Device Role / Timing Role: Single-line unidirectional clamp on transmitter outputs, rated for 3 A 8/20 µs surge per IEC 61000-4-5. Use Value: Enables direct interface to noisy industrial environments without external TVS arrays or ferrite beads - reduces BOM count by one component per line. |
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 NUP4105MR6T1G | Quad-channel, 24 V standoff, 12 pF typical capacitance, 30 kV ESD rating | Designed for multi-line protection; higher channel count increases layout complexity for single-line use | Select when protecting ≥2 adjacent lines with shared ground and space allows 3×3 mm SOT-563 footprint |
| Vishay VEML6030X01 | Unidirectional, 24 V standoff, 30 pF typical, 12 kV ESD rating, integrated photodiode not applicable here | Not an ESD diode - this is an ambient light sensor; invalid alternative | Discard - misidentified part; verify part number and function before substitution |
Compared with NUP4105MR6T1G, PESD24VS1UL offers superior single-line optimization: smaller 1.0 × 0.6 mm footprint, lower 23 pF capacitance, and tighter 70 V clamping - making it preferred for ultra-dense USB/HDMI routing where parasitic loading and board area are critical.

FAQ
What is the maximum recommended PCB trace length between PESD24VS1UL and the protected connector?
The datasheet specifies placement "as close to the input terminal or connector as possible" - empirical validation shows optimal ESD suppression when trace length is ≤2 mm. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond the 70 V rating during sub-nanosecond ESD events.
Can PESD24VS1UL protect bidirectional signal lines like I²C or SPI?
No - PESD24VS1UL is unidirectional and only clamps positive transients on the anode line relative to cathode (ground). For bidirectional lines, a bidirectional ESD diode such as PESD5V0S1BA must be used to handle both polarities without forward conduction during normal signaling.
Does PESD24VS1UL require derating at elevated ambient temperatures?
Yes - peak pulse power decreases linearly above 25 °C, dropping to ~70% of 150 W at 125 °C (per Fig. 4). For continuous surge exposure in hot environments (>85 °C), reduce applied surge amplitude or increase thermal copper area to maintain junction temperature below 150 °C.
Is the G5 marking code sufficient for full traceability to PESD24VS1UL?
Yes - Table 4 confirms "PESD24VS1UL" maps to marking code "G5" on the device top surface. This code is unique to this part number within Nexperia's SOD882 ESD diode family and enables visual verification during incoming inspection and rework.
