Product details
Overview
PESD5V0S1BAF 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 - deployed in USB 2.0 data lines of portable consumer electronics.
For engineers reviewing the PESD5V0S1BAF datasheet, PESD5V0S1BAF pinout, PESD5V0S1BAF application, or PESD5V0S1BAF equivalent, key selection criteria include low clamping voltage for signal integrity preservation, sub-50 pF capacitance for high-speed interface compatibility, bidirectional polarity handling, and SOD323 footprint constraints in space-constrained PCB layouts.
Technical Context
This dual-cathode, bidirectional TVS diode implements a symmetrical back-to-back PN junction configuration across pins 1 and 2, enabling clamping of both positive and negative transients without polarity biasing. It operates within ±30 kV ESD stress per IEC 61000-4-2 and withstands 12 A 8/20 µs surge pulses per IEC 61000-4-5.
The device exhibits 50 Ω differential resistance and maintains <5 nA leakage at 5 V reverse bias, ensuring minimal loading on sensitive analog or high-impedance signal paths. Its thermal design supports continuous operation up to 150 °C junction temperature, with derated peak pulse power above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous DC voltage the line can carry without triggering conduction. |
| Clamping Voltage | 14 V at 12 A - Peak voltage seen by protected circuit during worst-case 8/20 µs surge event. |
| Diode Capacitance | 35–45 pF at 0 V, 1 MHz - Low enough to avoid signal distortion on USB 2.0 (480 Mbps) and audio I²S lines. |
| ESD Withstand | ±30 kV contact discharge per IEC 61000-4-2 level 4 - Meets industrial and consumer ESD immunity requirements. |
| Peak Pulse Power | 130 W (8/20 µs) - Sustains transient energy without degradation in single-event surge conditions. |
| Leakage Current | 5 nA max at 5 V - Negligible DC loading on battery-powered sensor or audio bias networks. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.3 mm pitch, 1.7 × 1.25 × 0.95 mm body, cathode-marked end (bar) aligned with Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Forms one half of symmetrical clamp; connects to protected line when used in bidirectional configuration. |
| 2 | Cathode (Diode 2) | Completes back-to-back diode pair; referenced to ground or common return path in standard layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Clamping | Enables protection of AC-coupled or bipolar signal lines (e.g., USB D+/D−, audio differential pairs) without external bias. |
| Low 14 V Clamping at 12 A | Keeps downstream ICs (e.g., USB transceivers) within safe operating voltage during surge events. |
| 35–45 pF Capacitance | Preserves signal rise/fall times on 480 Mbps USB 2.0 links; avoids jitter or eye closure in high-speed interfaces. |
| 5 nA Reverse Leakage | Prevents battery drain in always-on portable devices and avoids DC offset in precision analog front-ends. |
| SOD323 Footprint | Minimizes PCB real estate in compact designs (e.g., earbuds, wearables); compatible with standard reflow profiles. |
Applications
| USB 2.0 Interface Protection | Smartphone Audio Jack ESD Guard |

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 SZ1.5SMC5.0AT3G | Unidirectional, higher 5.0 V VRWM but 100 V VBR; 100 pF capacitance; DO-214AB package. | Requires separate diodes per polarity; unsuitable for AC-coupled lines like USB; better for DC power rail protection. | Select only if protecting unidirectional DC signals with higher surge margin and board space available. |
| Vishay VEML6030X01 | Not an ESD diode - ambient light sensor with integrated I²C interface; functionally unrelated. | N/A - incorrect functional category; not a protection device. | Exclude from ESD protection evaluation; verify part number before sourcing. |
Compared with PESD5V0S1BAF, SZ1.5SMC5.0AT3G offers higher surge robustness but lacks bidirectionality and adds 2× capacitance, degrading high-speed signal fidelity; VEML6030X01 is a sensor, not a protection component - confirming strict functional alignment is essential for replacement validation.

FAQ
What is the maximum operating temperature for PESD5V0S1BAF?
The PESD5V0S1BAF supports continuous operation up to 150 °C junction temperature, with derating applied above 25 °C ambient per Figure 4 in the datasheet. Its SOD323 package enables efficient heat dissipation in thermally constrained layouts, and storage temperature range extends from −65 °C to +150 °C.
Does PESD5V0S1BAF require external biasing for bidirectional protection?
No - PESD5V0S1BAF uses an internal back-to-back diode structure with two cathodes (Pins 1 and 2), enabling intrinsic bidirectional clamping without external resistors, capacitors, or DC bias. This allows direct placement across any AC-coupled or bipolar signal pair such as USB D+/D− or audio differential lines.
How does the 35–45 pF capacitance impact USB 2.0 signal integrity?
At 480 Mbps, USB 2.0 tolerates ≤50 pF total line capacitance; PESD5V0S1BAF's 35–45 pF ensures full compliance while preserving rise/fall times and minimizing eye diagram closure. Layout best practices (short traces, ground plane) further limit added parasitic capacitance to maintain signal fidelity.
Can PESD5V0S1BAF replace PESD5V0S1BA in existing designs?
Yes - PESD5V0S1BAF is a form-, fit-, and function-compatible variant of PESD5V0S1BA, sharing identical electrical specs, SOD323 package dimensions, pinout, and marking (E6). The 'F' suffix denotes tape-and-reel packaging per latest ordering codes; no schematic or layout changes are required for drop-in replacement.
