Product details
Overview
PESD18VF1BSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small SMD package, designed to protect a single high-speed signal line against ±10 kV IEC 61000-4-2 contact discharge. It delivers 0.28 pF typical diode capacitance, 18 V reverse standoff voltage, and clamps transients to ≤16 V at 1 A peak pulse current-enabling use in NFC antenna and USB 2.0 data line protection.
For engineers reviewing the PESD18VF1BSF datasheet, PESD18VF1BSF pinout, PESD18VF1BSF application, or PESD18VF1BSF equivalent, key selection criteria include ultra-low capacitance for signal integrity, bidirectional clamping symmetry, IEC-compliant ESD robustness, and compatibility with 0.6 × 0.3 mm PCB footprints in space-constrained RF and mobile interfaces.
Technical Context
This device implements a dual-cathode, bidirectional TVS structure optimized for low-capacitance transient suppression on AC-coupled or bipolar signal lines. Its symmetrical V-I characteristics ensure identical clamping behavior for positive and negative ESD events, with dynamic resistance of 0.6 Ω enabling fast response under TLP stress.
The diode operates within a −45 °C to +125 °C junction temperature range and maintains <30 nA reverse leakage at 18 V VRWM. Its 8/20 µs surge rating supports 1 A peak pulse current, while layout-sensitive performance requires placement within 2 mm of the protected connector per application guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Diode capacitance (Cd) | 0.28 pF typ @ 1 MHz, 0 V - preserves signal integrity on >100 MHz NFC and USB 2.0 lines |
| Reverse standoff voltage (VRWM) | 18 V - ensures no conduction during normal 3.3 V or 5 V signal operation |
| ESD rating (IEC 61000-4-2) | ±10 kV contact, ±15 kV air - meets industrial and portable electronics immunity requirements |
| Clamping voltage (VCL) | ≤16 V @ IPPM = 1 A - limits transient overvoltage to safe levels for downstream IC inputs |
| Dynamic resistance (Rdyn) | 0.6 Ω @ 5 A TLP - enables rapid energy shunting with minimal voltage overshoot |
| Reverse leakage (IRM) | 1–30 nA @ VR = 18 V - avoids DC loading on sensitive analog or RF front-end circuits |

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 ESDE0402E01800 | 0.35 pF typ capacitance; 18 V VRWM; ±15 kV air discharge only | Larger 0402 footprint (1.0 × 0.5 mm); higher parasitic inductance limits >500 MHz use | Select when board space allows larger package and air-discharge immunity is primary concern |
| Vishay VEML6030X01 | 0.25 pF typ; 15 V VRWM; ±8 kV contact rating; integrated photodiode not relevant here | Optical sensor package-mechanically incompatible; not intended as ESD-only replacement | Avoid-functional mismatch; photodiode integration creates unnecessary complexity and cost |

FAQ
What is the maximum recommended PCB trace length between PESD18VF1BSF and the protected connector?
Per Nexperia application guidance, the trace length from the device to the protected I/O pad must be ≤2 mm to minimize inductance-induced voltage overshoot during ESD events. Longer traces degrade clamping effectiveness and may cause failure to meet IEC 61000-4-2 requirements. Ground return path length must also be minimized using dedicated vias to inner ground planes.
Can PESD18VF1BSF be used for protecting 3.3 V GPIO lines in microcontrollers?
Yes-its 18 V VRWM provides ample margin above 3.3 V rail voltages, and its <30 nA reverse leakage at 18 V ensures negligible DC loading on GPIOs. The 0.28 pF capacitance avoids signal rise/fall time degradation, making it suitable for both digital and analog GPIO protection where ESD immunity is required.
Does PESD18VF1BSF require external series impedance for optimal ESD performance?
No external resistor is required for basic ESD protection. However, adding a small series resistor (e.g., 10–33 Ω) between the diode and protected IC can reduce ringing and improve clamping consistency under fast-rising transients-particularly beneficial in >1 GHz RF paths where PCB parasitics dominate.
Is PESD18VF1BSF qualified for automotive applications per AEC-Q200?
No-this device is not AEC-Q200 qualified. Nexperia explicitly states in the datasheet legal disclaimers that non-automotive qualified products like PESD18VF1BSF are unsuitable for automotive use unless separately validated. For automotive-grade ESD protection, consult Nexperia's AEC-Q200-certified PESDxUx family.
