Product details
Overview
PESD24VS1ULD-Q from Nexperia is a unidirectional ESD protection diode in SOD882D (DFN1006D-2) package, designed to protect one signal line against IEC 61000-4-2 contact discharge up to 23 kV and IEC 61000-4-5 surges (IPP = 3 A). It features 24 V reverse standoff voltage, 70 V clamping voltage at 3 A, and ultra-low 23 pF typical capacitance - ideal for high-speed USB 2.0, HDMI, or automotive infotainment data lines.
For engineers reviewing the PESD24VS1ULD-Q datasheet, PESD24VS1ULD-Q pinout, PESD24VS1ULD-Q application, or PESD24VS1ULD-Q equivalent, key selection criteria include clamping performance under 3 A surge, sub-1 nA leakage at 24 V, AEC-Q101 qualification, and compatibility with 0.65 mm pitch PCB layouts requiring side-wettable flanks.
Technical Context
This device operates as a single-line unidirectional TVS diode, leveraging silicon avalanche breakdown to clamp transients while maintaining low dynamic resistance (1.6 Ω typical) and fast response to ESD pulses (sub-1 ns rise time per IEC 61000-4-2). Its cathode-anode polarity defines conduction only during positive transients relative to ground.
The SOD882D package enables placement within 2 mm of I/O connectors, minimizing inductance in the transient path. Thermal derating follows a defined curve: peak pulse power drops to ~60% at 125 °C junction temperature, supporting operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V reverse standoff voltage - ensures no conduction during normal 24 V rail or signal swing operation. |
| VCL @ IPP = 3 A | 70 V clamping voltage - limits transient overshoot to safe levels for downstream 3.3 V/5 V logic interfaces. |
| Cd @ 1 MHz | 23 pF typical capacitance - preserves signal integrity on USB 2.0 (480 Mbps) and audio differential pairs. |
| IPP | 3 A peak pulse current (8/20 µs) - meets IEC 61000-4-5 Level 2 surge immunity requirements. |
| ESD Rating | 23 kV contact discharge per IEC 61000-4-2 Level 4 - exceeds industrial and automotive ESD robustness mandates. |
| IRM @ VRWM | <1 nA reverse leakage - prevents DC loading on high-impedance sensor or bias networks. |
| Package | SOD882D (DFN1006D-2), 1.0 × 0.6 × 0.4 mm - supports ultra-dense layout with side-wettable flanks for automated optical inspection (AOI). |
Pinout & Package
SOD882D is a 2-terminal leadless plastic package with visible side pads for solder joint inspection. Body dimensions are 1.0 mm × 0.6 mm × 0.4 mm, pitch 0.65 mm, and cathode indicated by a marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line; conducts when line voltage exceeds VRWM + VBR, shunting surge to ground. |
| 2 | Anode (A) | Connected to system ground; completes low-inductance return path for ESD current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including infotainment and ADAS sensor interfaces with full temperature range (-55 °C to +150 °C). |
| Side-wettable flanks | Enables reliable automated optical inspection (AOI) of solder joints without X-ray, reducing post-SMT defect escape. |
| Low clamping voltage | 70 V at 3 A ensures protected ICs (e.g., USB transceivers) remain below absolute maximum ratings during surge events. |
| Ultra-low leakage | <1 nA at 24 V prevents signal distortion in precision analog front-ends or battery-monitoring circuits. |
| Small footprint | 1.0 × 0.6 mm area saves >60% board space vs. SOT23 packages - critical for compact portable electronics. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB peripherals exposed to frequent handling and static-prone environments. IC Role / Device Role: Unidirectional transient voltage suppressor placed directly at USB connector, with cathode to signal and anode to chassis ground. Use Value: 23 pF capacitance avoids signal integrity degradation at 480 Mbps, while 23 kV ESD rating prevents port failure during user insertion. |
Use Scenario: Safeguarding HDMI CEC and HPD pins in TVs and set-top boxes subject to repeated cable plugging/unplugging. IC Role / Device Role: Single-line ESD clamp on HPD (pin 19), referenced to ground, blocking negative transients only. Use Value: 24 V VRWM matches HDMI HPD logic threshold; 70 V clamping prevents latch-up in HDMI controller GPIOs. |
| Automotive Infotainment | Industrial Sensor Interfaces |
Use Scenario: Protecting CAN FD or LIN bus signal lines in head units where ESD coupling occurs via display bezels or control knobs. IC Role / Device Role: Unidirectional clamp on signal line referenced to vehicle chassis ground, leveraging AEC-Q101 qualification. Use Value: Operation up to +150 °C junction temperature ensures reliability in sealed enclosures near displays or amplifiers. |
Use Scenario: Shielding RS-485 or analog sensor inputs (e.g., 4–20 mA loop) in factory automation PLC modules mounted near motor drives. IC Role / Device Role: Point-of-entry protection on field-side I/O terminals, with cathode to signal and anode to isolated ground plane. Use Value: 3 A surge rating withstands repetitive electrical fast transients (EFT) from nearby switching loads without degradation. |
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 NUP4105LT1G | Higher 30 V VRWM; 100 pF capacitance; SOT-553 package (larger, 1.6 × 1.6 mm). | Less suitable for high-speed interfaces; better for 24 V industrial I/O where speed is secondary to higher standoff. | Select when VRWM margin >6 V is required and board space allows larger footprint. |
| Vishay VEML6030X01 | Not applicable - this is an ambient light sensor, not an ESD diode; excluded from valid alternatives. | N/A | Not a functional alternative; discard from comparison. |
Compared with PESD24VS1ULD-Q, NUP4105LT1G trades 23 pF/24 V/1.0×0.6 mm for 100 pF/30 V/1.6×1.6 mm - making it viable only where lower frequency signals and relaxed layout constraints exist; no other validated unidirectional SOD882D alternative meets identical AEC-Q101 + 23 kV + 23 pF specs.

FAQ
What is the maximum operating temperature for PESD24VS1ULD-Q?
The device supports ambient temperatures from −55 °C to +150 °C and junction temperatures up to +150 °C. Derating of peak pulse power begins above +25 °C, reaching ~60% of 150 W at +125 °C junction temperature, as confirmed in Figure 5 of the official datasheet.
Is PESD24VS1ULD-Q compatible with lead-free reflow processes?
Yes - it is qualified for standard lead-free reflow profiles per J-STD-020, with a maximum peak temperature of 260 °C. The SOD882D package uses matte tin plating on side pads, enabling reliable wetting and void-free solder joints under IPC-A-610 Class 2 conditions.
How does the marking bar relate to pin 1 on the SOD882D package?
The marking bar on the top surface aligns with pin 1 (cathode), as shown in Figure 1 and Table 2 of the datasheet. When viewing the device in top-down orientation with the bar on the left, pin 1 is the left terminal and pin 2 (anode) is the right terminal.
Can PESD24VS1ULD-Q protect bidirectional signal lines like RS-485?
No - it is unidirectional and only clamps positive transients on the cathode line. For bidirectional protection (e.g., RS-485), two devices back-to-back or a dedicated bidirectional ESD array such as PESD5V0S1BA is required to handle both polarities.
