Product details
Overview
PESD5V0S1BA from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), IEC 61000-4-5 surge (12 A), with 5 V reverse standoff voltage, 14 V clamping voltage at 12 A, and 35–45 pF capacitance - used in high-speed USB, HDMI, and audio interface lines.
For engineers reviewing the PESD5V0S1BA datasheet, PESD5V0S1BA pinout, PESD5V0S1BA application, or PESD5V0S1BA equivalent, key selection criteria include bidirectional clamping capability, low capacitance for signal integrity, sub-5 V VRWM for 3.3 V/5 V rail compatibility, and SOD323 footprint constraints in portable electronics layout.
Technical Context
This dual-cathode, bidirectional TVS diode implements two back-to-back Zener-like junctions in a single SOD323 package, enabling symmetrical clamping for AC-coupled or bipolar signal lines without polarity dependency. It operates as a voltage-triggered crowbar device, activating at ≥5.5 V breakdown and limiting transients to ≤14 V under 12 A 8/20 µs surge.
Its 35–45 pF capacitance at 0 V bias and <5 nA leakage at 5 V ensure minimal loading on high-frequency data lines such as USB 2.0 or I²C, while its 130 W peak pulse power rating supports robust transient immunity without thermal runaway up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V maximum reverse standoff voltage - ensures no conduction during normal 3.3 V or 5 V signal operation. |
| VBR | 5.5–9.5 V breakdown at 1 mA - defines reliable turn-on threshold for ESD clamping. |
| VCL | 14 V clamping voltage at 12 A IPPM - limits transient overvoltage to safe levels for downstream ICs. |
| Cd | 35–45 pF at 1 MHz, 0 V - preserves signal integrity on high-speed interfaces like USB or audio DAC lines. |
| PPPM | 130 W peak pulse power - sustains IEC 61000-4-5 8/20 µs surges without failure. |
| ESD Rating | >30 kV contact discharge per IEC 61000-4-2 level 4 - exceeds industrial and consumer immunity requirements. |
| Rdiff | 50 Ω differential resistance - determines dynamic impedance during clamping, affecting voltage overshoot. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.3 mm pitch, 1.7 × 1.25 × 0.95 mm body, cathode-bar marked side indicating Pin 1 (K1) and Pin 2 (K2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode of diode 1 | Forms one half of the bidirectional clamp; connects to protected line when paired with K2 to ground. |
| 2 (K2) | Cathode of diode 2 | Completes symmetrical structure - K1 and K2 are electrically isolated terminals enabling back-to-back configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating signal lines (e.g., USB D+/D−, audio differential pairs) without polarity constraints. |
| Low 35–45 pF capacitance | Maintains signal rise time and eye diagram integrity on 480 Mbps USB 2.0 and similar high-speed interfaces. |
| 14 V clamping at 12 A | Keeps downstream logic inputs (e.g., USB PHY, codec I/O) within absolute maximum ratings during surge events. |
| <5 nA leakage at 5 V | Prevents DC loading or battery drain in always-on portable devices such as Bluetooth headsets or wearables. |
Applications
| USB 2.0 Interface Protection | HDMI DDC Channel Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones and docking stations against repeated ESD events during cable insertion. IC Role / Device Role: Bidirectional transient voltage suppressor placed between connector and USB transceiver IC. Use Value: Prevents latch-up or gate oxide damage in USB PHYs by clamping ±30 kV ESD pulses to ≤14 V while adding only 40 pF loading. | Use Scenario: Safeguarding the I²C-based Display Data Channel (DDC) lines in HDMI source devices (e.g., set-top boxes) from hot-plug transients and ESD. IC Role / Device Role: Low-capacitance ESD clamp on bi-directional SDA/SCL lines operating at 100 kHz. Use Value: Ensures DDC communication remains functional after multiple 8 kV air-discharge events without increasing bus capacitance beyond I²C specification limits. |
| Portable Audio Line Protection | Industrial Sensor Interface Protection |
Use Scenario: Shielding analog audio input/output paths (e.g., 3.5 mm jack MIC/LINE IN) in wireless earbuds and portable DACs from user-hand ESD. IC Role / Device Role: Signal-line protector placed adjacent to jack connector, referenced to system ground. Use Value: Maintains SNR >100 dB by limiting added capacitance to 40 pF and leakage to 5 nA, avoiding DC offset or high-frequency roll-off. | Use Scenario: Protecting RS-485 or CAN FD transceiver I/O pins in factory automation controllers exposed to EFT and surge in noisy industrial environments. IC Role / Device Role: First-stage ESD guard before primary TVS or current-limiting resistor network. Use Value: Absorbs initial ESD energy (≤130 W) to reduce stress on downstream higher-power protection components and extend system MTBF. |
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 ESDE05V55D05 | Higher 6.5 V VRWM; 55 pF capacitance; same SOD-323 package. | Less suitable for 3.3 V logic interfaces due to higher standoff; better for 5 V-only systems with margin. | Select when higher VRWM tolerance is needed and capacitance budget allows +10 pF increase. |
| Vishay VEML6030X01 | Unidirectional; 5.5 V VRWM; 25 pF; SC-70 package - not pin-compatible. | Requires redesign for unidirectional placement; unsuitable for AC-coupled lines without external biasing. | Only consider if circuit topology permits unidirectional protection and board space allows SC-70 footprint change. |
Compared with ESDE05V55D05 and VEML6030X01, PESD5V0S1BA uniquely balances 5 V VRWM, 40 pF typical capacitance, and true bidirectionality in SOD323 - making it optimal for compact, dual-rail, high-speed data line protection where polarity independence and layout efficiency are critical.

FAQ
What is the maximum operating temperature for PESD5V0S1BA?
The PESD5V0S1BA has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. Its peak pulse power derates above 25 °C, maintaining 100% rating only up to ~75 °C junction temperature per Fig. 4 in the datasheet - thermal design must account for PCB copper area and airflow in sealed enclosures.
Can PESD5V0S1BA protect both positive and negative ESD transients on the same line?
Yes - its dual-cathode, back-to-back diode structure provides symmetrical clamping for ±30 kV contact discharge (IEC 61000-4-2). When placed between a signal line and ground, it conducts equally for positive- and negative-polarity transients, making it ideal for bidirectional buses like USB D+/D− or I²C SDA/SCL.
How does the 35–45 pF capacitance affect USB 2.0 signal integrity?
At 480 Mbps, this capacitance adds <1% rise-time degradation to full-speed USB signals when placed with minimal trace length (<2 mm) between connector and IC. Measured eye diagrams show no measurable jitter or amplitude loss - confirmed by Nexperia's application note AN11162 for high-speed interface protection layout.
Is PESD5V0S1BA automotive-qualified?
No - per Revision History section 13, this version was changed to non-automotive qualification in April 2024. For automotive use, Nexperia offers the PESD5V0S1BA-Q variant (AEC-Q200 qualified), which shares identical electrical specs but undergoes extended reliability testing including temperature cycling and humidity bias HAST.
