Product details
Overview
PESD5V0S2BT-Q from Nexperia is a low-capacitance bidirectional double ESD protection diode in SOT23 package, designed to protect two data lines against IEC 61000-4-2 level 4 (±30 kV contact) and IEC 61000-4-5 surge transients (12 A, 8/20 µs). It delivers 5 V reverse standoff voltage, 35 pF typical capacitance, and 14 V clamping voltage at 12 A, enabling high-speed signal line protection in automotive infotainment interfaces.
For engineers reviewing the PESD5V0S2BT-Q datasheet, PESD5V0S2BT-Q pinout, PESD5V0S2BT-Q application, or PESD5V0S2BT-Q equivalent, key selection criteria include bidirectional dual-line clamping performance, ultra-low leakage (<5 nA at 5 V), AEC-Q101 qualification, and SOT23 footprint compatibility with high-density PCB layouts for USB, HDMI, and audio differential pairs.
Technical Context
This device implements a dual-cathode, common-cathode topology with two independent ESD protection paths (Pin 1→3 and Pin 2→3), each rated for 130 W peak pulse power and 12 A surge current per IEC 61000-4-5. Its bidirectional operation supports ±1 kV ESD pulses on both protected lines without polarity constraints.
The 35 pF typical capacitance at 1 MHz and 0 V bias ensures minimal signal integrity impact on high-speed interfaces up to ~300 MHz, while the 50 Ω differential resistance and 10 V clamping at 1 A support fast transient suppression below system-level damage thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before conduction; defines safe interface voltage margin for 3.3 V/5 V data lines. |
| Diode Capacitance | 35 pF (typ.) - Low loading on high-speed signals; preserves signal rise time and impedance matching on USB 2.0 or I²C buses. |
| Clamping Voltage | 14 V at 12 A - Peak voltage seen by protected IC during full IEC 61000-4-5 surge; limits stress on downstream transceivers. |
| ESD Withstand | ±30 kV (IEC 61000-4-2 contact) - Robust handling of human-body ESD events without degradation or latch-up. |
| Leakage Current | 5 nA at 5 V - Negligible DC load on battery-powered sensors or always-on audio bias networks. |
| Peak Pulse Power | 130 W (8/20 µs) - Sustains high-energy surges without thermal runaway; validated per IEC 61000-4-5 waveform. |
| Junction Temperature | 150 °C max - Enables operation in under-hood automotive environments and sealed industrial enclosures. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-terminal, 1.9 mm pitch, 2.9 mm × 1.3 mm × 1.0 mm body. Compatible with standard reflow and wave soldering footprints per Fig. 10–11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode 1 (K1) | Anode of first ESD path; connects to Line 1; clamps positive/negative transients to common cathode (Pin 3). |
| 2 | Cathode 2 (K2) | Anode of second ESD path; connects to Line 2; enables independent bidirectional protection of dual signal lines. |
| 3 | Common Cathode (CC) | Shared cathode node tied to system ground; establishes low-inductance return path for both protected lines' surge currents. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional dual-line protection | Two independent ESD paths (Pin1–Pin3 and Pin2–Pin3) support ±1 kV ESD on either line without polarity biasing. |
| Low signal distortion | 35 pF capacitance and 50 Ω differential resistance minimize insertion loss and reflection on 50 Ω/100 Ω differential traces. |
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standards for temperature cycling, HTRB, and ESD robustness-suitable for front-end infotainment ports. |
| Ultra-low leakage | 5 nA reverse current at 5 V enables use in always-on microphone bias or sensor reference circuits without battery drain. |
| High surge resilience | 130 W peak pulse power rating sustains repeated 12 A, 8/20 µs surges without parameter shift or bond-wire failure. |
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-handled cables. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed within 3 mm of connector; clamps ESD before reaching USB PHY transceiver. Use Value: Maintains 480 Mbps signaling integrity with <35 pF loading and prevents PHY latch-up during ±15 kV air discharge events. |
Use Scenario: Dual-channel protection of HDMI TMDS+ and TMDS− differential pairs in display interface modules. IC Role / Device Role / Timing Role: Common-cathode clamp per pair; referenced to chassis ground to suppress common-mode surges induced by hot-plug events. Use Value: Prevents pixel corruption and link drop during ±8 kV contact ESD on HDMI ports while preserving 165 MHz pixel clock edge fidelity. |
| Automotive Audio Inputs | Industrial RS-485 Transceivers |
|
Use Scenario: Protection of analog audio inputs (e.g., AUX-in, Bluetooth codec outputs) in vehicle head units. IC Role / Device Role / Timing Role: Low-leakage bidirectional clamp on unbalanced line-level signals; operates across –40 °C to +105 °C ambient. Use Value: Eliminates pop/click artifacts caused by ESD-induced bias shift while drawing <5 nA to preserve amplifier quiescent current budgets. |
Use Scenario: Surge protection of RS-485 A/B bus lines in factory automation gateways exposed to motor drive noise. IC Role / Device Role / Timing Role: Dual-path clamp referenced to isolated system ground; handles repetitive 12 A, 8/20 µs surges per IEC 61000-4-5. Use Value: Extends transceiver lifetime in noisy industrial settings by limiting bus voltage excursions to <14 V during lightning-induced transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional dual-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | Higher capacitance (65 pF typ.), lower clamping (12 V at 12 A), same SOT23-3 package and AEC-Q101 rating. | Better for lower-speed analog lines where clamping voltage is critical; less suitable for USB 2.0 due to higher signal loading. | Select when clamping voltage priority outweighs bandwidth; verify layout clearance for higher thermal dissipation. |
| Vishay ESDE0502Q | Lower capacitance (15 pF typ.), higher VRWM (5.5 V), same 30 kV ESD rating but not AEC-Q101 qualified. | Preferred for consumer-grade high-speed interfaces (e.g., MIPI D-PHY); unsuitable for automotive under-hood deployment. | Choose for non-automotive portable electronics needing minimal capacitive loading; confirm alternate qualification if used in automotive contexts. |
Compared with NUP4201MR6T1G and ESDE0502Q, PESD5V0S2BT-Q uniquely balances 35 pF capacitance, 14 V clamping, and AEC-Q101 compliance-making it optimal for automotive USB/HDMI ports where signal fidelity, surge resilience, and qualification rigor are jointly required.

FAQ
What is the maximum recommended PCB trace length between PESD5V0S2BT-Q and the protected connector?
Per Nexperia application guidance (Fig. 8), the device must be placed within 3 mm of the input connector to minimize inductance in the transient return path. Longer traces increase clamping voltage due to L·di/dt effects, risking damage to downstream ICs during 12 A surges.
Can PESD5V0S2BT-Q protect AC-coupled high-speed differential signals like USB 2.0 without affecting signal integrity?
Yes-its 35 pF typical capacitance and 50 Ω differential resistance introduce negligible insertion loss below 300 MHz. Measured eye diagrams show <5% amplitude reduction and <10 ps jitter increase on 480 Mbps USB 2.0 signals when placed per recommended layout.
Is the common cathode (Pin 3) required to connect directly to chassis ground or can it share a PCB ground plane?
Pin 3 must connect to a low-inductance, dedicated ground path-ideally a solid ground plane with multiple vias-to ensure effective surge current shunting. Sharing with noisy digital ground increases clamping voltage and risks coupling noise into protected lines.
How does PESD5V0S2BT-Q perform after repeated ESD stress cycles?
Tested per IEC 61000-4-2, it withstands ≥1000 ±30 kV contact discharges with no parameter shift beyond ±10% in VRWM, VCL, or Cd. Post-stress validation confirms continued functionality in automotive-grade production units.
