Product details
Overview
PESD15VL1BA from Nexperia is a low-capacitance bidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect a single signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 15 V reverse standoff voltage, 16 pF capacitance at 1 MHz, and 44 V clamping voltage at 5 A surge current. It serves in high-speed data lines where signal integrity and transient immunity are critical.
For engineers reviewing the PESD15VL1BA datasheet, PESD15VL1BA pinout, PESD15VL1BA application, or PESD15VL1BA equivalent, key selection criteria include sub-20 pF capacitance for USB/USB-C/HDMI signal lines, bidirectional clamping symmetry, ultra-low leakage (<50 nA), IEC 61000-4-5 surge rating (5 A, 8/20 µs), and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This dual-cathode bidirectional TVS diode implements a back-to-back Zener configuration in a single SOD323 package, enabling symmetrical clamping for AC-coupled or bipolar signal paths without polarity constraints. Its 17.1–20.3 V breakdown voltage ensures robust turn-on margin above the 15 V VRWM rating.
The device delivers 200 W peak pulse power handling per IEC 61000-4-5 with a differential resistance of 225 Ω at 1 mA, supporting fast transient suppression while minimizing voltage overshoot on protected lines. Its 1 nA typical reverse leakage at 15 V supports low-power sensor and audio interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse operating voltage before leakage rises significantly; sets upper limit for signal swing in protected line. |
| VBR | 17.1–20.3 V - Breakdown voltage at 5 mA; defines reliable conduction onset during transients while avoiding false triggering. |
| VCL @ 5 A | 44 V - Clamping voltage under 8/20 µs surge; determines maximum stress imposed on downstream ICs during ESD events. |
| Cd @ 1 MHz | 16 pF - Diode capacitance at 0 V bias; enables use on USB 2.0 (480 Mbps), HDMI, and other high-speed interfaces without signal degradation. |
| PPPM | 200 W - Peak pulse power rating per IEC 61000-4-5; confirms capability to absorb multi-joule surges without failure. |
| ESD Rating | ±30 kV contact / ±15 kV air per IEC 61000-4-2 level 4 - Validates suitability for handheld, industrial, and consumer ports exposed to frequent human ESD. |
| IRM @ 15 V | 1 nA typical - Ultra-low reverse leakage; preserves battery life and avoids loading of high-impedance analog or sensor inputs. |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 2-pin, 1.3 mm pitch, 1.7 × 1.25 × 0.95 mm body, cathode-marked side indicated by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode 1) | First cathode terminal of back-to-back Zener pair; connects to protected line when used as bidirectional clamp. |
| 2 | K2 (Cathode 2) | Second cathode terminal; completes symmetrical clamping path to ground for both positive and negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Back-to-back Zener structure enables identical response to ±ESD pulses without polarity dependency-ideal for AC-coupled data lines. |
| 16 pF capacitance | Minimizes insertion loss and signal distortion on 480 Mbps USB 2.0, audio DAC outputs, and I²S interfaces. |
| 44 V clamping at 5 A | Ensures downstream logic (e.g., USB PHY, HDMI receiver) remains below absolute maximum ratings during worst-case surge events. |
| 1 nA reverse leakage | Prevents DC loading of high-impedance nodes such as microphone bias circuits or precision sensor bridges. |
| IEC 61000-4-2 level 4 compliance | Validated for 30 kV contact discharge-meets stringent ESD immunity requirements for consumer and industrial front-panel interfaces. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protecting D+ and D− pins of USB 2.0 connectors against user-hand ESD during plug/unplug cycles. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector, shunting ESD energy to ground before reaching USB transceiver. Use Value: 16 pF capacitance avoids signal rise-time degradation; 44 V clamping prevents damage to internal PHY ESD structures rated ≤50 V. |
Use Scenario: Safeguarding HDMI DDC (I²C) and CEC control lines from ESD induced by cable handling or nearby static discharge. IC Role / Device Role: Low-leakage bidirectional clamp maintaining I²C bus integrity while suppressing ±15 kV air-discharge transients. Use Value: 1 nA IRM avoids pull-up resistor loading; symmetrical clamping preserves bidirectional clock/data signaling without DC offset. |
| Audio Line Outputs | Industrial RS-485 Terminals |
Use Scenario: Shielding line-level analog audio outputs (e.g., headphone jack, DAC output) from ESD during cable insertion or user touch. IC Role / Device Role: Signal-line protector placed adjacent to output connector, limiting transient overvoltage to <44 V peak. Use Value: Low capacitance prevents high-frequency roll-off; 15 V VRWM accommodates ±12 V audio swing without forward conduction. |
Use Scenario: Protecting RS-485 transceiver A/B terminals in factory automation gateways exposed to field wiring ESD and lightning-induced surges. IC Role / Device Role: First-stage surge limiter absorbing IEC 61000-4-5 5 A (8/20 µs) transients before they reach isolated transceiver IC. Use Value: 200 W PPPM rating handles multi-pulse surge stress; SOD323 footprint allows placement within 2 mm of connector per layout guidelines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Higher capacitance (30 pF), lower clamping (33 V @ 5 A), same SOD-323 package. | Better for lower-voltage systems (≤3.3 V IO) but unsuitable for >480 Mbps data rates due to bandwidth limitation. | Select when clamping voltage priority outweighs speed; avoid for USB 2.0 or HDMI. |
| Vishay ESDE0402MUT5G | Lower capacitance (0.3 pF), lower ESD rating (±15 kV), same VRWM (15 V), same package. | Optimized for RF antenna lines or ultra-high-speed SerDes; insufficient for IEC 61000-4-2 level 4 compliance. | Choose only for sub-1 GHz RF paths requiring minimal capacitive loading; not drop-in for general-purpose ESD protection. |
Compared with NUP4105MR6T1G and ESDE0402MUT5G, PESD15VL1BA uniquely balances 16 pF capacitance, ±30 kV ESD rating, and 44 V clamping-making it the optimal choice for cost-sensitive, high-volume USB/HDMI protection where both speed and robustness are required.

FAQ
What is the maximum recommended PCB trace length between PESD15VL1BA and the protected connector?
Per Nexperia application guidance, the trace from PESD15VL1BA to the protected line must be ≤2 mm, and the ground return path must be direct and low-inductance-ideally via multiple vias to an inner ground plane. Longer traces increase inductance, degrading clamping performance and allowing voltage overshoot beyond the 44 V spec during fast ESD events.
Can PESD15VL1BA be used to protect a 3.3 V I/O line without risk of forward conduction?
Yes. With a 15 V VRWM and 17.1 V minimum breakdown voltage, PESD15VL1BA remains fully non-conductive under normal 3.3 V operation-even with noise margins and tolerances. Its 1 nA leakage at 15 V ensures negligible loading on 3.3 V logic, making it safe for GPIO, UART, and I²C protection without affecting signal levels.
Does PESD15VL1BA meet automotive qualification standards?
No. Per Nexperia's revision history (v.3, April 2023), PESD15VL1BA is explicitly designated as non-automotive qualified. It lacks AEC-Q200 stress testing and automotive temperature range validation. For automotive applications, Nexperia offers the -Q qualified PESDx1BA-Q series with extended temperature and reliability validation.
How does the dual-cathode pinning (K1/K2) affect PCB layout versus a standard unidirectional diode?
The K1/K2 pinning requires symmetric routing: both pins connect to the same protected line, with the common cathode node tied to ground through the shortest possible path. Unlike unidirectional diodes, no anode reference is needed-eliminating polarity concerns but mandating equal trace impedance to each cathode to preserve bidirectional clamping symmetry during fast transients.
