Product details
Overview
PESD15VS1UL from Nexperia is a unidirectional ESD protection diode in a DFN1006-2 (SOD882) package, designed to protect single high-speed signal lines against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (5 A, 8/20 µs). It delivers 150 W peak pulse power, clamps at ≤40 V under 5 A transient, and exhibits ultra-low leakage (<1 nA at 15 V) and low capacitance (32–70 pF at 1 MHz), enabling use on USB 2.0, HDMI, and audio data lines.
For engineers reviewing the PESD15VS1UL datasheet, PESD15VS1UL pinout, PESD15VS1UL application, or PESD15VS1UL equivalent, this page provides verified technical context, validated pin roles, real-world application deployment guidance, and confirmed automotive-grade alternatives for signal-line ESD hardening in space-constrained designs.
Technical Context
The PESD15VS1UL operates as a unidirectional avalanche diode with reverse standoff voltage of 15 V and breakdown at 17.6–18.4 V (5 mA test current). Its clamping behavior is defined by non-repetitive 8/20 µs surges up to 5 A, delivering ≤40 V clamping voltage and 225 Ω differential resistance at 1 mA forward bias.
Designed for placement directly at I/O connectors, it relies on minimal PCB trace inductance to achieve effective transient suppression. Its 32–70 pF capacitance is specified at 0 V reverse bias and 1 MHz, making it suitable for signals up to ~300 Mbps without significant edge degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - Maximum continuous DC voltage the line can carry before diode conduction begins; defines safe operating margin for 3.3 V or 5 V logic interfaces. |
| Clamping Voltage | 40 V max at 5 A (8/20 µs) - Peak voltage seen by protected IC during worst-case surge; ensures downstream logic remains below absolute maximum ratings. |
| Diode Capacitance | 32–70 pF at 1 MHz, 0 V - Low enough to avoid signal integrity loss on USB 2.0 (480 Mbps) and analog audio lines; measured across full production lot. |
| ESD Rating | ±30 kV contact per IEC 61000-4-2 Level 4 - Validated for 10 non-repetitive discharges; exceeds industrial and automotive ESD immunity requirements. |
| Peak Pulse Power | 150 W at 25 °C - Sustains 8/20 µs transients up to 5 A without failure; derates to ~75 W at 125 °C junction temperature. |
| Leakage Current | <1 nA at 15 V - Negligible loading on high-impedance sensor or reference lines; avoids drift or offset errors in precision analog paths. |
Pinout & Package
DFN1006-2 (SOD882) package: leadless, ultra-small surface-mount plastic case measuring 1.0 mm × 0.6 mm × 0.48 mm with 0.65 mm pitch; cathode indicated by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected signal line; conducts transient current toward ground when line voltage exceeds VRWM + VBR; marking bar identifies this terminal. |
| 2 | Anode (A) | Connected to system ground; completes low-inductance return path for ESD/surge current; must be tied to solid ground plane with minimal trace length. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive environments including temperature cycling (-55 °C to +150 °C), humidity, and mechanical shock-enabling use in infotainment and ADAS I/O protection. |
| Ultra-low capacitance variation | Capacitance remains stable (32–70 pF) across 0–15 V reverse bias, ensuring consistent signal integrity on bidirectional or AC-coupled lines like USB D+/D−. |
| Sub-1 nA leakage | Enables direct placement on battery-backed or high-Z sensor inputs (e.g., microphone bias lines) without measurable current drain or voltage error. |
| 150 W peak pulse rating | Supports robust protection against lightning-induced surges and cable discharge events in industrial Ethernet and RS-485 interfaces. |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 ports against ESD during cable insertion or handling. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed within 2 mm of connector, shunting transients to ground before reaching USB transceiver. Use Value: Maintains <70 pF total line capacitance to preserve 480 Mbps eye diagram integrity while surviving ±15 kV air/±8 kV contact ESD per IEC 61000-4-2. |
Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) line from ESD during display connection/disconnection. IC Role / Device Role / Timing Role: Standoff-rated diode blocking 5 V DC bias while clamping fast ESD pulses to <40 V to prevent false HPD toggling or sink-driver damage. Use Value: Prevents spurious display detection or loss due to ESD-induced voltage overshoot, with leakage <1 nA avoiding HPD pull-up current error. |
| Automotive Infotainment Audio | Industrial RS-232/485 Interfaces |
Use Scenario: Protecting analog audio input/output lines (e.g., AUX-in, speaker outputs) in car head units exposed to user-handling ESD. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to chassis ground, absorbing ±30 kV contact discharges without distorting 20 Hz–20 kHz audio band. Use Value: Eliminates audible pop/crackle during ESD events and meets AEC-Q101 for under-hood temperature stability up to 150 °C junction. |
Use Scenario: Shielding RS-232 TX/RX or RS-485 A/B lines in factory automation equipment from cable discharge and induced surges. IC Role / Device Role / Timing Role: Line-to-ground transient suppressor rated for 5 A (8/20 µs), placed adjacent to DB9/DB25 connector to limit voltage excursion to transceiver ICs. Use Value: Enables reliable operation in noisy industrial environments with >150 W surge handling and <40 V clamping, reducing field failures from transient-induced latch-up. |
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 capacitance (100 pF typ), lower clamping (33 V @ 5 A), dual-channel configuration | Requires PCB layout adaptation for dual-line protection; less suitable for single-line, ultra-low-capacitance needs like USB 2.0 | Select when protecting two adjacent lines (e.g., CAN H/L) with shared ground and higher surge margin is acceptable. |
| Vishay ESDE15V5U2C | Same 15 V VRWM, but lower peak power (100 W), tighter capacitance range (25–35 pF), AEC-Q101 qualified | Better for bandwidth-critical applications needing <35 pF, but reduced surge robustness for high-energy industrial transients | Prefer when signal speed exceeds 600 Mbps (e.g., LVDS) and surge exposure is limited to IEC 61000-4-2 only. |
Compared with NUP4105MR6T1G and ESDE15V5U2C, the PESD15VS1UL offers the optimal balance of ultra-low leakage (<1 nA), moderate capacitance (32–70 pF), and high 150 W surge capability-making it preferred for single-line, automotive-grade, space-constrained ESD protection where both precision analog integrity and robust transient handling are required.

FAQ
What is the maximum operating temperature for PESD15VS1UL?
The PESD15VS1UL has a maximum junction temperature of 150 °C and an ambient operating range of −55 °C to +150 °C. Its peak pulse power derates linearly above 25 °C, dropping to approximately 75 W at 125 °C junction temperature, as confirmed in Figure 4 of the official datasheet.
Can PESD15VS1UL be used for bidirectional signal protection?
No-PESD15VS1UL is strictly unidirectional and only protects signals with defined polarity relative to ground (e.g., positive-only or negative-only lines). For bidirectional lines like USB D+/D− or HDMI TMDS, a symmetric dual-diode array or dedicated bidirectional ESD device is required.
How does the 0.65 mm pitch DFN1006-2 package impact PCB layout?
The 0.65 mm pitch requires precise stencil design and reflow profile control; Figure 10 in the datasheet specifies a recommended solder paste footprint with 0.3 mm wide pads and 0.7 mm pad length. Misalignment or excessive solder volume risks bridging between the anode and cathode terminals.
Is PESD15VS1UL compatible with lead-free reflow processes?
Yes-the device is qualified for standard lead-free reflow per JEDEC J-STD-020, with a peak temperature of 260 °C for up to 30 seconds. The DFN1006-2 package uses matte tin plating and withstands multiple reflow cycles without delamination or parameter shift.
