Product details
Overview
PESD5V0S1BA-Q 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), with 5 V reverse standoff voltage, 14 V clamping voltage at 12 A surge, and 35 pF typical capacitance - deployed in USB, HDMI, and audio interface lines of automotive infotainment systems.
For engineers reviewing the PESD5V0S1BA-Q datasheet, PESD5V0S1BA-Q pinout, PESD5V0S1BA-Q application, or PESD5V0S1BA-Q equivalent, key selection criteria include clamping performance under 8/20 µs surges, low capacitance for high-speed data integrity, AEC-Q101 qualification for automotive reliability, and dual-cathode configuration for bidirectional transient suppression.
Technical Context
This device implements a dual-cathode, back-to-back diode structure enabling symmetrical clamping for ± polarity transients on a single line. Its 50 Ω differential resistance and 14 V clamping voltage at 12 A ensure fast response and low-voltage overshoot during IEC 61000-4-5 surge events.
Qualified per AEC-Q101, it operates across −55 °C to +150 °C ambient and supports automotive-grade board-level ESD immunity without derating up to 125 °C junction temperature. The 35 pF capacitance at 0 V bias enables use on 480 Mbps USB 2.0 and 3 Gbps HDMI 1.4a interfaces.
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 (8/20 µs) - Peak voltage seen by protected IC during worst-case surge, limiting stress on downstream logic. |
| Diode Capacitance | 35 pF typical at 1 MHz, 0 V - Low enough to avoid signal integrity degradation on USB 2.0 and audio differential pairs. |
| ESD Withstand | ±30 kV contact per IEC 61000-4-2 level 4 - Meets automotive and industrial system-level ESD immunity requirements. |
| Peak Pulse Power | 130 W per diode - Sustains transient energy from coupled surges without thermal failure. |
| Leakage Current | 5 nA at 5 V - Negligible loading on battery-powered sensor or audio bias networks. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-pin, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-marked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | K1 (Cathode of Diode 1) | Anode connects internally to Pin 2; forms first half of bidirectional clamp path toward ground. |
| 2 | K2 (Cathode of Diode 2) | Anode connects internally to Pin 1; completes symmetrical clamp for negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Single-device solution for ± transient suppression on one line, eliminating need for discrete dual-diode arrays. |
| AEC-Q101 qualified | Validated for automotive applications including infotainment, ADAS sensors, and body control modules. |
| Low 35 pF capacitance | Preserves signal rise/fall times on high-speed interfaces up to 3 Gbps without equalization overhead. |
| 14 V clamping at 12 A | Provides tighter voltage limiting than generic 5 V TVS diodes (typically >18 V), reducing IC stress margin. |
| 5 nA leakage at 5 V | Enables direct placement on always-on sensor or microphone bias rails without battery drain impact. |
Applications
| USB 2.0 Data Lines | HDMI 1.4a TMDS Channels |
|---|---|
Use Scenario: ESD protection on D+ and D− lines of automotive USB host ports exposed to user insertion events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed within 3 mm of USB connector to minimize inductance. Use Value: Clamps ±30 kV contact discharges to ≤14 V, preventing latch-up or gate oxide damage in USB PHY ICs. |
Use Scenario: Protection of TMDS clock and data channels in vehicle display head units receiving HDMI signals from media controllers. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp mounted directly at HDMI receptacle pins to preserve 165 MHz pixel clock integrity. Use Value: 35 pF capacitance avoids signal reflection and jitter accumulation, maintaining eye diagram compliance at 3 Gbps. |
| Automotive Audio Line Inputs | CAN FD Transceiver I/O Pins |
Use Scenario: Protecting analog audio inputs (e.g., AUX-in, Bluetooth codec outputs) in car radios from handling ESD. IC Role / Device Role / Timing Role: Signal-line protector between connector and audio ADC/driver, operating in linear region below 5 V. Use Value: 5 nA leakage prevents DC offset shift in high-impedance audio paths; 14 V clamping avoids clipping distortion during transients. |
Use Scenario: Secondary ESD protection on CAN FD transceiver RX/TX pins where primary protection resides at connector. IC Role / Device Role / Timing Role: Localized clamp adjacent to transceiver die to suppress fast-rising ESD pulses before internal protection triggers. Use Value: Dual-cathode symmetry ensures identical clamping for dominant/recessive bus states; AEC-Q101 rating matches transceiver qualification. |
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 NUP4201MR6T1G | Higher 22 V clamping at 12 A; 55 pF capacitance; SOT-23 package (larger footprint). | Less suitable for >480 Mbps interfaces due to higher capacitance; better for lower-speed CAN or LIN lines. | Select when board space allows larger SOT-23 and clamping voltage margin >22 V is acceptable. |
| Vishay VEML6030X01 | Unidirectional only; 5.5 V standoff; 12 V clamping; 15 pF capacitance; not AEC-Q101 qualified. | Lacks bidirectional capability and automotive qualification; limited to consumer-grade portable electronics. | Choose only for cost-sensitive non-automotive designs where unidirectional protection suffices and 15 pF is critical. |
Compared with NUP4201MR6T1G and VEML6030X01, PESD5V0S1BA-Q uniquely balances automotive qualification, bidirectional clamping, low 35 pF capacitance, and compact SOD323 footprint - making it optimal for space-constrained, high-reliability signal-line protection in modern vehicles.

FAQ
What is the maximum peak pulse current PESD5V0S1BA-Q can handle?
The device is rated for 12 A peak pulse current under IEC 61000-4-5 8/20 µs waveform conditions. This value is validated per absolute maximum ratings and confirmed in the datasheet's limiting values table (Table 5). It applies to both pins simultaneously in the bidirectional configuration, with clamping voltage measured across pins 1 and 2.
Is PESD5V0S1BA-Q suitable for protecting USB 3.0 SuperSpeed lines?
No - its 35 pF typical capacitance exceeds the <1 pF requirement for USB 3.0 Gen 1 (5 Gbps) differential pairs. It is validated for USB 2.0 (480 Mbps) and HDMI 1.4a (3 Gbps) where 35 pF maintains acceptable eye margin, as confirmed in Nexperia's application guidance and signal integrity simulations.
How does the dual-cathode pinning affect PCB layout?
Pins 1 and 2 are both cathodes with internal anodes cross-connected, forming a symmetric clamp. Layout requires equal-length, short traces (<3 mm) from each pin to the protected line and ground plane - no directional orientation needed. The marking bar aligns with Pin 1 (K1), simplifying automated optical inspection.
Does PESD5V0S1BA-Q require external series impedance for optimal ESD performance?
No external resistor is required. The device's 50 Ω differential resistance provides inherent current limiting during ESD events. Adding series impedance would degrade clamping speed and increase voltage overshoot; Nexperia's recommended layout places it directly at the connector with minimal trace inductance, as specified in Section 10 of the datasheet.
