Product details
Overview
PESD24VS1ULD from Nexperia is a unidirectional ESD protection diode in SOD882D (DFN1006D-2) package, designed to protect one signal line 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, 70 V clamping voltage at 3 A, and 23 pF typical capacitance - deployed in USB, HDMI, and audio interface lines of portable electronics.
For engineers reviewing the PESD24VS1ULD datasheet, PESD24VS1ULD pinout, PESD24VS1ULD application, or PESD24VS1ULD equivalent, this page delivers verified electrical parameters, validated SOD882D footprint layout, real-world clamping behavior under 3 A transient stress, and direct alternatives for high-speed signal line protection where low capacitance and sub-1 nA leakage are critical.
Technical Context
This device operates as a single-line unidirectional TVS diode, leveraging silicon PN junction avalanche breakdown to clamp transients above 26.5 V while maintaining <1 nA reverse leakage at 24 V. Its ultra-low 23 pF capacitance enables use on 480 Mbps USB 2.0 and 1080p HDMI data lanes without signal integrity degradation.
The SOD882D package integrates solderable side-wettable flanks for automated optical inspection (AOI) and thermal performance matching that supports 150 W peak pulse power dissipation. Clamping occurs within nanoseconds of ESD onset, with dynamic resistance of 1.6 Ω measured via TLP at 10 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V reverse standoff voltage - ensures no conduction during normal 24 V DC operation, preserving signal integrity on protected lines. |
| VCL @ IPP = 3 A | 70 V clamping voltage - limits transient overvoltage to safe levels for downstream ICs rated ≤75 V absolute max. |
| Cd @ 1 MHz | 23 pF typical diode capacitance - enables use on high-speed interfaces up to 480 Mbps without measurable rise-time degradation. |
| IPP (surge) | 3 A peak pulse current (8/20 µs) - withstands IEC 61000-4-5 line-to-ground surges common in industrial port interfaces. |
| ESD rating | 23 kV contact discharge per IEC 61000-4-2 level 4 - exceeds consumer and industrial ESD immunity requirements. |
| IRM @ VRWM | <1 nA reverse leakage - prevents DC loading on high-impedance sensor or reference signal paths. |
| PPPM | 150 W peak pulse power - sustains energy-limited transients without thermal runaway in compact PCB layouts. |
Pinout & Package
Package: DFN1006D-2 (SOD882D), leadless ultra-small surface-mount plastic package measuring 1.0 mm × 0.6 mm × 0.4 mm with side-wettable flanks for reliable reflow and AOI compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to ground or lower-potential rail; marked by cathode bar; carries clamped transient current to GND. |
| 2 | Anode (A) | Connected to protected signal line; accepts positive-going ESD/surge events; forward-biased during negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 Level 4 ESD protection | 23 kV contact discharge - eliminates need for external spark gaps or multi-stage protection on exposed ports. |
| Solderable side-wettable flanks | Enables automated optical inspection (AOI) of solder joints - critical for high-reliability portable and medical PCB assemblies. |
| Ultra-low 0.37 mm package height | Reduces board stack height in space-constrained designs such as smartphones, wearables, and thin tablets. |
| Low clamping voltage (70 V @ 3 A) | Protects 3.3 V–24 V logic and analog ICs without requiring additional series impedance or voltage translators. |
| 23 pF capacitance at 0 V bias | Maintains signal fidelity on USB 2.0, DisplayPort AUX, and I²C lines without added termination or equalization. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detect (HPD) |
|---|---|

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 | Higher 30 V VRWM; 100 pF capacitance; 120 W PPPM; dual-channel configuration. | Requires PCB redesign for dual-line protection; unsuitable for >100 Mbps interfaces due to capacitance. | Select when protecting two adjacent lines (e.g., CAN_H/CAN_L) and higher standoff voltage is needed. |
| Vishay ESDE0402MUT5G | 24 V VRWM; 15 pF capacitance; 20 kV ESD rating; 0.35 mm height; same SOD882D footprint. | Lower clamping voltage (60 V @ 3 A); tighter Cd tolerance (12–18 pF); automotive-qualified (-Q variant available). | Prefer for automotive infotainment USB ports or where sub-20 pF capacitance is mandatory for 5 Gbps USB 3.2 Gen 1. |
Compared with NUP4105MR6T1G, PESD24VS1ULD offers 47% lower capacitance for high-speed signal integrity; versus ESDE0402MUT5G, it trades 10 kV ESD margin for broader industrial qualification and identical footprint compatibility without automotive cost premium.

FAQ
What is the maximum operating temperature for PESD24VS1ULD?
The PESD24VS1ULD has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance (RθJA) is not specified in the datasheet, but the 0.4 mm package height and side-wettable flanks enable effective heat dissipation in standard FR-4 PCBs with 1 oz copper and minimal thermal pads.
Can PESD24VS1ULD be used on bidirectional signal lines like I²C or UART?
No - PESD24VS1ULD is unidirectional and only protects against transients with polarity aligned to its anode-to-cathode orientation. For bidirectional lines, a symmetric dual-diode array (e.g., PESD5V0S1BA) or back-to-back configuration is required to clamp both positive and negative excursions.
Is the SOD882D package compatible with standard reflow profiles?
Yes - the SOD882D package is qualified for IPC/JEDEC J-STD-020D reflow, supporting peak temperatures up to 260 °C. The recommended reflow footprint (Fig. 12) specifies 0.6 mm pad width and 1.4 mm overall land length to ensure solder joint reliability and AOI visibility of side-wettable flanks.
Does PESD24VS1ULD meet automotive AEC-Q200 requirements?
No - the PESD24VS1ULD is explicitly designated as non-automotive qualified per its revision history (v.3, May 2024). Nexperia offers automotive-qualified alternatives (e.g., PESD24VS1UL-Q) with extended temperature testing, enhanced ESD robustness, and full AEC-Q200 certification for vehicle applications.
