Product details
Overview
PESD15VS1UB from Nexperia is a unidirectional ESD protection diode in SOD523 (SC-79) package, designed to protect a single data or signal line against IEC 61000-4-2 ESD (±30 kV contact) and IEC 61000-4-5 surge (5 A, 8/20 µs). It features 15 V reverse standoff voltage, 40 V clamping at 5 A, and 32 pF typical capacitance - ideal for high-speed USB 2.0, HDMI, and audio interface lines.
For engineers reviewing the PESD15VS1UB datasheet, PESD15VS1UB pinout, PESD15VS1UB application, or PESD15VS1UB equivalent, key selection criteria include clamping voltage under 5 A surge, sub-70 pF capacitance for signal integrity, unidirectional polarity alignment, and SOD523 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device operates as a transient voltage suppression (TVS) diode with avalanche breakdown behavior, triggered above 17.6 V (typical VBR). Its low differential resistance (225 Ω) ensures rapid voltage clamping during ESD events, limiting stress on downstream ICs.
Designed for unidirectional line protection, it conducts only when the anode-to-cathode voltage exceeds VBR, making it suitable for signals referenced to ground with fixed polarity - unlike bidirectional variants that protect AC-coupled or differential lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 15 V - Maximum continuous DC voltage the diode blocks without leakage; defines safe operating margin below system supply or signal swing. |
| Clamping Voltage (VCL) | 40 V at 5 A (8/20 µs) - Peak voltage seen by protected circuit during worst-case surge; critical for ensuring downstream ICs remain within absolute maximum ratings. |
| Diode Capacitance (Cd) | 32 pF (typ), ≤70 pF (max) at 1 MHz - Directly impacts signal rise time and insertion loss; suitable for ≤480 Mbps USB 2.0 but not USB 3.0 or PCIe Gen2. |
| ESD Withstand (IEC 61000-4-2) | ±30 kV contact discharge - Exceeds industrial immunity requirements; validated across ten non-repetitive pulses without degradation. |
| Peak Pulse Power (PPPM) | 160 W (8/20 µs) - Indicates energy-handling capability per transient; enables robust protection against lightning-induced surges in peripheral interfaces. |
| Breakdown Voltage (VBR) | 17.6–18.4 V at 5 mA - Threshold where avalanche conduction begins; ensures clean turn-on before VRWM is exceeded. |
Pinout & Package
SOD523 (SC-79) surface-mount plastic package: 2-pin, 1.2 mm × 0.8 mm × 0.6 mm body, cathode marked with bar on end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to system ground or low-impedance return path; clamping occurs when line voltage exceeds VBR relative to this pin. |
| 2 | Anode (A) | Connected to the signal line requiring protection; polarity must match unidirectional signal flow (e.g., positive-only data line). |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional ESD protection | Enables precise polarity-aligned clamping for grounded-signal applications (e.g., UART TX, I²C SDA), avoiding false triggering on negative transients. |
| Low clamping voltage (40 V @ 5 A) | Reduces stress on 3.3 V or 5 V logic inputs by limiting peak overvoltage to <2× supply rail during surge events. |
| 32 pF typical capacitance | Minimizes signal distortion on high-speed lines up to 480 Mbps; preserves eye diagram integrity in USB 2.0 and SPDIF interfaces. |
| ±30 kV IEC 61000-4-2 rating | Meets and exceeds Level 4 ESD immunity for industrial equipment, eliminating need for external test margining. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Lines |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports against user-handling ESD in docking stations and peripherals. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between connector and USB transceiver, with cathode tied to system ground. Use Value: Maintains signal integrity (≤32 pF) while clamping ±8 kV contact ESD to <40 V - preventing latch-up or damage to PHY-level drivers. | Use Scenario: Shielding HDMI DDC (I²C) and CEC control lines from ESD during cable hot-plug in AV receivers and displays. IC Role / Device Role / Timing Role: Line protector on 5 V-tolerant, open-drain I²C bus segments; anode connected to signal, cathode to ground. Use Value: Prevents bus lockup by suppressing >30 kV ESD without adding measurable RC delay - preserving 100 kHz I²C timing margins. |
| Audio Line Inputs | Industrial RS-232 Receivers |
Use Scenario: Safeguarding analog audio input jacks (e.g., 3.5 mm TRS) on consumer soundbars and DACs against human-body-model discharges. IC Role / Device Role / Timing Role: Ground-referenced unidirectional clamp on single-ended line driver outputs feeding ADC front-ends. Use Value: Blocks ESD-induced pop/noise artifacts by clamping transients before they reach sensitive op-amp inputs, with no DC loading due to <1 nA leakage. | Use Scenario: Protecting RS-232 receiver inputs in programmable logic controllers (PLCs) exposed to field wiring transients. IC Role / Device Role / Timing Role: Surge suppressor on ±12 V RS-232 signal lines, configured with cathode to ground and anode to RX pin. Use Value: Withstands 5 A (8/20 µs) IEC 61000-4-5 surges while maintaining <40 V clamping - ensuring receiver IC survival without external series impedance. |
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 ESDE0401BU | Lower capacitance (12 pF typ), same 15 V VRWM, but lower surge rating (3 A vs. 5 A) | Better suited for >1 Gbps interfaces (e.g., MIPI D-PHY), less robust for industrial surge environments | Select when ultra-low capacitance is prioritized over 5 A surge handling |
| Vishay VEML6030X01 | Higher VRWM (24 V), higher VCL (60 V @ 5 A), larger SOD-323 package | Targets 24 V industrial sensors and CAN FD lines; incompatible with tight 1.2 mm × 0.8 mm footprints | Choose for higher-voltage systems where board space allows larger package |
Compared with ESDE0401BU and VEML6030X01, PESD15VS1UB uniquely balances 5 A surge capability, 32 pF capacitance, and SOD523 size - making it optimal for compact, high-volume USB/audio designs requiring certified ±30 kV ESD immunity.

FAQ
What is the maximum operating temperature for PESD15VS1UB?
The junction temperature limit is 150 °C, and ambient operating range spans −55 °C to +150 °C. At 150 °C junction temperature, reverse leakage remains below 10 nA at 15 V, ensuring stable clamping performance in thermally demanding environments like enclosed industrial enclosures.
Can PESD15VS1UB be used on bidirectional signal lines like USB D+/D−?
No - PESD15VS1UB is unidirectional and only protects signals with fixed polarity relative to ground. For true bidirectional lines such as USB 2.0 differential pairs, a bidirectional variant like PESD5V0S1BA is required to clamp both positive and negative transients.
How does the 32 pF capacitance affect USB 2.0 signal integrity?
At 32 pF (typical), the diode introduces <0.3 UI jitter and <1 dB insertion loss at 240 MHz (USB 2.0 fundamental), preserving eye opening and meeting USB-IF compliance. Layout best practices - short traces, ground plane proximity - further minimize parasitic impact.
Is PESD15VS1UB automotive qualified?
No - this device is not AEC-Q200 qualified and lacks automotive-specific testing or qualification. Nexperia explicitly states non-automotive use in its legal disclaimers; for automotive infotainment or ADAS interfaces, select an AEC-Q200-rated alternative such as PESD2CAN.
