Product details
Overview
PESD30VF1BSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) ultra-small SMD package, designed to protect single high-speed data lines with 30 V reverse standoff voltage, 0.19 pF typical capacitance, and ±10 kV IEC 61000-4-2 contact discharge rating-used in USB3.2 and HDMI2.0 interfaces.
For engineers reviewing the PESD30VF1BSF datasheet, PESD30VF1BSF pinout, PESD30VF1BSF application, or PESD30VF1BSF equivalent, key selection criteria include ultra-low capacitance for signal integrity, snap-back clamping behavior for low-voltage protection of sensitive I/Os, and validated performance on bidirectional high-frequency lines.
Technical Context
This device implements a bidirectional snap-back clamping structure with negative dynamic resistance, enabling sub-20.5 V clamping at 16 A TLP current while maintaining <0.8 Ω dynamic resistance in both polarities. Its design targets transient suppression on lines carrying AC-coupled or bipolar signals relative to ground.
The DSN0603-2 package provides an extremely low-inductance path to ground via symmetric cathode terminals (K1/K2), minimizing parasitic impedance in the protection loop-critical for preserving signal fidelity above 1 GHz, as confirmed by insertion loss <−10 dB up to 10 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | ±30 V reverse standoff voltage-ensures no leakage or conduction during normal operation of 3.3 V/5 V/12 V data lines. |
| Cd | 0.19 pF typical capacitance at 1 MHz and 0 V bias-minimizes signal distortion on USB3.2 Gen1 (5 Gbps) and HDMI2.0 (6 Gbps) channels. |
| VCL | 20.5 V clamping voltage at 16 A TLP pulse-limits voltage seen by downstream ICs below absolute maximum ratings of modern PHYs. |
| ESD Rating | ±10 kV per IEC 61000-4-2 contact discharge-meets industrial and consumer end-equipment immunity requirements. |
| Rdyn | 0.8 Ω dynamic resistance at ±7.5 A-ensures rapid energy shunting with minimal voltage overshoot during fast transients. |
| Package | DSN0603-2 (SOD962-2), 0.6 mm × 0.3 mm × 0.3 mm-enables placement within 1 mm of connectors without PCB real estate penalty. |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, ultra-small surface-mount package with two terminals and 0.4 mm pitch. The marking bar indicates the cathode side; both terminals serve as cathodes for opposing polarity clamping paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K1) | Cathode for positive-going transient path | Provides low-impedance clamp to ground when line voltage exceeds +31 V (VBR min), initiating snap-back conduction. |
| 2 (K2) | Cathode for negative-going transient path | Provides low-impedance clamp to ground when line voltage falls below −31 V (VBR min), enabling symmetrical bidirectional protection. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional snap-back clamping | Enables protection of AC-coupled or floating data lines without DC bias constraints-no need for external pull-up/down resistors. |
| 0.19 pF capacitance | Preserves signal rise/fall times and eye diagram integrity on 5–6 Gbps serial links, verified by S21 insertion loss <−10 dB up to 10 GHz. |
| Sub-20.5 V clamping at 16 A | Protects 1.8 V/3.3 V I/O cells with margin below 24 V absolute maximum ratings-prevents latch-up or oxide breakdown in companion ICs. |
| DSN0603-2 footprint | 0.6 mm × 0.3 mm body size allows placement directly adjacent to USB/HDMI connector pads-reducing transient loop inductance to <0.2 nH. |
Applications
| USB3.2 Gen1 Interface Protection | HDMI2.0 Data Lane Protection |

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 ESD9B3.3ST5G | 3.3 V VRWM, 0.65 pF capacitance-higher capacitance limits use to ≤480 Mbps interfaces. | Suitable for USB2.0 or UART lines; not recommended for USB3.2/HDMI2.0 due to bandwidth limitation. | Select only if protecting lower-speed lines where 3.3 V standoff suffices and board space permits larger SOD-923 package. |
| Vishay VEML3010 | Unidirectional configuration, 30 V VRWM, 0.35 pF-requires dual-device implementation for bidirectional protection. | Needs two devices per line, increasing BOM count and PCB area; lacks snap-back clamping behavior. | Consider only when unidirectional protection suffices and layout allows separate anode/cathode routing to ground. |
Compared with ESD9B3.3ST5G and VEML3010, PESD30VF1BSF uniquely combines 30 V bidirectional standoff, 0.19 pF capacitance, and snap-back clamping in a single DSN0603-2 device-enabling direct drop-in protection for high-speed differential interfaces without redesign.

FAQ
What is the maximum recommended trace length between PESD30VF1BSF and the protected connector?
The datasheet specifies placement "as close to the input terminal or connector as possible" to minimize inductance. For optimal ESD suppression, keep the total trace length-including both signal and ground return paths-to ≤1 mm. Longer traces increase clamping voltage due to L·di/dt effects, degrading protection effectiveness above 1 GHz.
Can PESD30VF1BSF be used on power rails such as VBUS in USB applications?
No. PESD30VF1BSF is rated for ±30 V standoff and intended solely for signal-line protection. It lacks overcurrent capability and thermal mass for sustained power-rail surge events. For VBUS protection, use dedicated TVS diodes like PESD5V0S1BA with higher peak pulse power and unidirectional architecture.
Does PESD30VF1BSF require a dedicated ground plane connection?
Yes. The device relies on an ultra-low-inductance path to ground to achieve its specified clamping performance. A solid ground plane with multiple vias near the cathode terminals is mandatory. Split or fragmented ground planes increase transient impedance and raise clamping voltage beyond 20.5 V during ESD events.
How does the snap-back behavior affect system-level ESD testing compliance?
Snap-back reduces clamping voltage significantly below traditional Zener-based devices-enabling consistent pass rates in IEC 61000-4-2 Level 4 (±8 kV contact) testing. However, it requires careful layout: prolonged snap-back can cause thermal stress if DC overvoltage persists, so ensure protected lines remain within VRWM during normal operation.
