Product details
Overview
PESD15VL1BA from Nexperia is a low-capacitance bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard single signal lines against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 15 V reverse standoff voltage, 16 pF capacitance at 1 MHz, 44 V clamping voltage at 5 A surge, and 1 nA leakage at 15 V - deployed in high-speed USB 2.0 and HDMI data lines.
For engineers reviewing the PESD15VL1BA datasheet, PESD15VL1BA pinout, PESD15VL1BA application, or PESD15VL1BA equivalent, key selection criteria include sub-20 pF capacitance for signal integrity, bidirectional clamping symmetry, 15 V working voltage margin, and SOD323 footprint compatibility with space-constrained PCB layouts.
Technical Context
This device implements a dual-cathode, back-to-back diode configuration enabling symmetrical clamping for ±15 V bidirectional signal lines without polarity constraints. Its ultra-low 16 pF capacitance minimizes signal distortion on high-frequency interfaces up to 480 Mbps.
Clamping occurs via avalanche breakdown at ~18.9 V (typical VBR), limiting transient voltage to ≤44 V under 5 A (8/20 µs) surge per IEC 61000-4-5, while maintaining <1 nA reverse leakage at rated VRWM - critical for battery-powered sensor nodes and low-power audio circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 15 V - maximum continuous DC or RMS signal voltage before leakage rises significantly; defines safe operating range for protected line. |
| Diode Capacitance | 16 pF at 1 MHz, 0 V bias - ensures minimal loading on high-speed digital signals (e.g., USB 2.0 eye diagram compliance). |
| Clamping Voltage | 44 V at 5 A (8/20 µs) - peak voltage seen by downstream IC during worst-case surge; protects 3.3 V/5 V logic inputs. |
| ESD Withstand | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial immunity requirements for exposed connectors. |
| Peak Pulse Power | 200 W (non-repetitive, 8/20 µs) - sustains short-duration surges without thermal runaway or parametric shift. |
| Reverse Leakage | 1 nA at 15 V, 25 °C - negligible current draw in battery-operated systems; avoids signal offset or power drain. |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 2-pin, 1.3 mm pitch, 1.7 × 1.25 × 0.95 mm body; marking bar denotes cathode side; compatible with standard reflow soldering profiles (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Anode of first diode connects internally to Pin 2; enables bidirectional conduction when either pin goes >15 V above or <15 V below ground. |
| 2 | Cathode (Diode 2) | Anode of second diode connects internally to Pin 1; forms symmetrical clamp pair protecting AC-coupled or bipolar signal paths. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Single-device solution for ±15 V signal lines (e.g., RS-485, audio differential pairs), eliminating need for two discrete diodes. |
| Low 16 pF capacitance | Maintains signal rise/fall times on 480 Mbps USB 2.0 traces; avoids jitter accumulation and bit-error-rate degradation. |
| 44 V clamping at 5 A | Keeps downstream 3.3 V transceivers within absolute maximum ratings during IEC 61000-4-5 surge events. |
| 1 nA reverse leakage | Enables use in always-on sensor interfaces without measurable battery drain or reference voltage perturbation. |
| 30 kV ESD robustness | Meets EN 61000-4-2 Level 4 for front-panel USB/HDMI ports in consumer electronics without derating. |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
|
Use Scenario: Protection of D+ and D− pins on USB 2.0 host/device connectors exposed to user-handling ESD. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 3 mm of connector, clamping ±30 kV discharges before reaching PHY IC. Use Value: Preserves 480 Mbps data integrity with <0.5% eye closure due to 16 pF loading and fast 1 ns response time. |
Use Scenario: ESD safeguard for TMDS clock and data channels on HDMI source/sink ports in AV receivers and monitors. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp on each differential pair, referenced to shield ground to suppress common-mode surges. Use Value: Prevents pixel corruption and hot-plug detection failure by limiting transient overvoltage to <44 V during connector insertion. |
| Industrial RS-485 Bus Nodes | Portable Audio Line Outputs |
|
Use Scenario: Transient protection for half-duplex RS-485 transceivers in factory automation gateways with long cable runs. IC Role / Device Role / Timing Role: Bidirectional clamp on A/B bus lines, absorbing IEC 61000-4-5 surges up to 5 A while preserving DC common-mode range. Use Value: Eliminates need for external series resistors or TVS arrays, reducing BOM count and board area by 40% vs. discrete solutions. |
Use Scenario: ESD hardening of unbalanced line-out jacks (3.5 mm TRS) in Bluetooth speakers and headphones. IC Role / Device Role / Timing Role: Ground-referenced shunt protector on left/right analog outputs, suppressing human-body-model (HBM) discharges up to 10 kV. Use Value: Prevents pop-noise and amplifier latch-up without degrading THD+N (<0.005%) due to ultra-low leakage and capacitance. |
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 22 pF capacitance; 12 V VRWM; 30 kV ESD rating; SOT-563 package (3.0 × 1.7 mm) | Larger footprint; lower working voltage limits use to 3.3 V-only lines; higher capacitance may affect >100 Mbps signals. | Select when board layout allows larger package and system operates below 12 V; avoid for USB 2.0 or HDMI. |
| Vishay ESDBLE5.0D1W | 12 pF capacitance; 5.0 V VRWM; 22 kV ESD rating; same SOD323 package; 30 V clamping at 4 A | Optimized for 5 V logic; insufficient standoff for 12–15 V analog lines; lower ESD rating reduces field reliability margin. | Prefer for 5 V microcontroller GPIO protection; not suitable for 15 V signal rails or industrial-level ESD immunity. |
Compared with NUP4105MR6T1G and ESDBLE5.0D1W, PESD15VL1BA uniquely balances 15 V standoff, 16 pF capacitance, and ±30 kV ESD rating in the smallest SOD323 footprint - making it optimal for space-constrained, mixed-voltage, high-speed interface protection where both signal fidelity and ruggedness are required.

FAQ
What is the maximum continuous operating voltage for PESD15VL1BA?
The PESD15VL1BA has a reverse standoff voltage (VRWM) of 15 V - meaning it can safely block up to 15 V DC or RMS signal voltage without significant leakage. Exceeding this voltage risks premature conduction and increased IRM, potentially degrading signal accuracy in analog or high-impedance digital lines.
Can PESD15VL1BA protect bidirectional analog signals like audio line-outs?
Yes - its symmetrical dual-diode structure provides identical clamping behavior for positive and negative transients, making it suitable for unbalanced analog outputs (e.g., 3.5 mm headphone jacks). At 1 nA leakage and 16 pF capacitance, it introduces no measurable DC offset or high-frequency attenuation in line-level audio paths.
How does the 44 V clamping voltage translate to system-level protection?
Under a 5 A, 8/20 µs surge (IEC 61000-4-5), the device limits voltage across protected lines to ≤44 V. For a 3.3 V transceiver with ±0.5 V absolute max ratings on I/O pins, this ensures the downstream IC remains within safe operating limits - provided PCB layout minimizes inductance in the clamping path.
Is PESD15VL1BA qualified for automotive applications?
No - the datasheet explicitly states this variant is non-automotive qualified. It lacks AEC-Q200 stress testing and automotive-grade process controls. For automotive use, Nexperia offers the PESD15VL1BA-Q variant, which undergoes extended temperature cycling, humidity testing, and ESD validation per automotive requirements.
