Product details
Overview
PESD18VF1BALS-Q from Nexperia is a bidirectional ESD protection diode in a DFN1006BD-2 (SOD882BD) package, designed to protect single high-speed signal lines against ±15 kV IEC 61000-4-2 contact discharge. It delivers ultra-low 0.38 pF capacitance at 1 MHz, 18 V reverse standoff voltage, and AEC-Q101 qualification for automotive NFC and antenna interfaces.
For engineers reviewing the PESD18VF1BALS-Q datasheet, PESD18VF1BALS-Q pinout, PESD18VF1BALS-Q application, or PESD18VF1BALS-Q equivalent, key selection criteria include sub-0.4 pF capacitance stability across bias, snap-back clamping behavior under TLP stress, cathode-terminal pin assignment for bidirectional line placement, and side-wettable flank compatibility with automated optical inspection.
Technical Context
This device implements a dual-cathode, bidirectional snap-back clamping structure optimized for transient suppression on symmetric data lines. Its negative dynamic resistance enables low clamping voltage (16.5 V at 8 A TLP) while maintaining <1 nA leakage at 18 V and stable capacitance below 0.47 pF up to 10 V reverse bias.
The DFN1006BD-2 package supports high-density routing with 0.65 mm pitch and side-wettable flanks for solder joint inspection. Thermal design leverages a 150 °C max junction temperature and -55 °C to +150 °C ambient operating range, validated per AEC-Q101 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 18 V - Maximum continuous DC voltage before leakage exceeds 1 µA; defines safe operating margin for 12 V/15 V signal rails. |
| Diode Capacitance (Cd) | 0.38 pF (typ) at 1 MHz, 0 V - Enables minimal signal distortion on >1 GHz NFC and USB 2.0 differential lines. |
| ESD Withstand (IEC 61000-4-2) | ±15 kV contact - Meets Level 4 immunity without external series impedance; verified with ten non-repetitive pulses. |
| Clamping Voltage (VCL) | 16.5 V at 8 A TLP - Limits transient overvoltage seen by downstream ICs during fast-rising ESD events. |
| Dynamic Resistance (Rdyn) | 0.7 Ω (typ) at 10 A TLP - Low impedance path during snap-back ensures rapid energy shunting to ground. |
| Breakdown Voltage (VBR) | 19–24 V at 10 mA - Defines onset of avalanche conduction; provides headroom above VRWM for margin. |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless ultra-small surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks and 0.65 mm pitch. The marking bar denotes the cathode side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K1) | Terminal for first diode anode connection; forms one half of bidirectional clamping path to ground. |
| 2 | Cathode (K2) | Terminal for second diode anode connection; completes symmetrical clamping for AC-coupled or bipolar signal lines. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low capacitance | 0.38 pF typ at 1 MHz - Preserves signal integrity on 13.56 MHz NFC and >480 Mbps USB 2.0 lines. |
| Snap-back clamping | Negative dynamic resistance triggers at ~19 V - Reduces clamping voltage by >30% vs. standard TVS during fast transients. |
| AEC-Q101 qualification | Qualified for automotive grade - Supports deployment in infotainment antennas, body control modules, and ADAS sensor interfaces. |
| Side-wettable flanks | 0.02 mm max solder protrusion - Enables automated X-ray and AOI verification of solder joint quality in high-reliability assembly. |
Applications
| NFC Antenna Protection | USB 2.0 Data Line Protection |
|---|---|
|
Use Scenario: Protecting 13.56 MHz RFID/NFC antenna traces from ESD during user handling or connector mating. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at antenna feedpoint to suppress ±15 kV contact discharge. Use Value: Sub-0.4 pF capacitance avoids detuning of LC resonance and maintains >95% antenna efficiency. |
Use Scenario: Shielding D+ and D− differential pairs in automotive USB host ports from ESD coupling via cables or chassis. IC Role / Device Role / Timing Role: Single-line protector deployed per signal line with cathodes tied to ground plane. Use Value: 16.5 V clamping at 8 A TLP prevents PHY layer latch-up while preserving eye diagram integrity at 480 Mbps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDBL5V0D1W | 0.5 pF capacitance, 5.5 V VRWM, SOD-923 package | Targeted at lower-voltage logic lines (1.8–3.3 V), not suitable for 12–15 V automotive signal rails | Select when protecting 3.3 V UART or I²C lines where lower VRWM is acceptable and higher capacitance is tolerable. |
| Vishay VEML3020X01 | 0.25 pF capacitance, 12 V VRWM, DFN1006-2 package | Lacks AEC-Q101 qualification; rated only for industrial temp range (-40 °C to +125 °C) | Use in cost-sensitive consumer electronics where automotive qualification is not required and 12 V standoff suffices. |
Compared with ESDBL5V0D1W and VEML3020X01, PESD18VF1BALS-Q uniquely combines 18 V standoff, 0.38 pF capacitance, and AEC-Q101 qualification-enabling robust protection of automotive-grade high-speed analog and digital signal lines without compromising RF performance or thermal reliability.

FAQ
What is the maximum recommended PCB trace length between PESD18VF1BALS-Q and the protected signal line?
Per Nexperia application guidance, the trace length from the diode to the protected line must be minimized-ideally ≤2 mm-and the return path to ground must be direct and low-inductance. Longer traces increase inductance, degrading clamping response during sub-nanosecond ESD events and raising peak voltage seen by downstream ICs.
Can PESD18VF1BALS-Q be used to protect a 5 V USB Type-C CC line?
Yes-it supports 5 V CC signaling with 18 V VRWM margin and 0.38 pF capacitance that avoids interference with CC logic thresholds. However, its bidirectional configuration requires both cathodes tied to ground, and it must be placed immediately adjacent to the connector to meet IEC 61000-4-2 Level 4 immunity without additional series impedance.
Does the snap-back behavior require external current limiting to prevent latch-up?
Yes-Nexperia explicitly warns against connecting unlimited DC current sources. After breakdown, the device enters low-impedance snap-back mode; sustained current >100 mA may cause thermal runaway. System design must ensure transient-only conduction, typically via series impedance or controlled drive strength upstream.
How does side-wettable flank geometry impact reflow soldering yield?
The side-wettable flanks enable automated optical inspection (AOI) of solder fillets on the package edges, improving defect detection for voids or insufficient wetting. Reflow profiles must follow Nexperia's recommended ramp rates and peak temperature (≤260 °C) to avoid delamination while ensuring full solder flow onto the flank surfaces.
