Product details
Overview
PESD3V3L1BSF from Nexperia is a bidirectional ESD protection diode in a DSN0603-2 (SOD962-2) package, designed to protect one signal line against IEC 61000-4-2 (±30 kV contact/air) and IEC 61000-4-5 (20 A surge) transients. It delivers 4.6 V typical clamping at 16 A TLP, 3.3 V reverse standoff voltage, and 32.5 pF capacitance at 1 MHz - optimized for high-speed USB, HDMI, and MIPI interface lines in portable electronics.
For engineers reviewing the PESD3V3L1BSF datasheet, PESD3V3L1BSF pinout, PESD3V3L1BSF application, or PESD3V3L1BSF equivalent, key selection criteria include ultra-low clamping voltage under 20 A surge, sub-1 nA leakage at 3.3 V, 0.3 mm height constraint, and verified bidirectional snap-back behavior per TLP testing.
Technical Context
This device implements a dual-cathode snap-back structure enabling symmetrical bidirectional clamping without polarity dependence. Its TLP-measured trigger voltage is 7.3 V and holding voltage is 3.7 V, supporting robust turn-on and low-voltage holdover during transient events.
The 0.05 Ω dynamic resistance at 20 A ensures minimal voltage overshoot during fast 8/20 µs surges, while 32.5 pF capacitance maintains signal integrity on data lines up to 1 Gbps. The DSN0603-2 footprint enforces tight layout control with 0.4 mm pitch and 0.6 × 0.3 mm body dimensions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3 V - Maximum continuous DC voltage the line can sustain before conduction begins. |
| Clamping Voltage | 5.6 V typical at 20 A (8/20 µs) - Peak voltage seen by protected IC during worst-case surge event. |
| ESD Rating | ±30 kV per IEC 61000-4-2 - Validated immunity to human-body-model discharges in handheld device interfaces. |
| Diode Capacitance | 32.5 pF at 0 V, 1 MHz - Low enough to avoid signal degradation on USB 2.0 and MIPI D-PHY lanes. |
| Leakage Current | 1 nA at 3.3 V - Negligible loading on battery-powered sensor or audio bias networks. |
| Package Dimensions | 0.6 mm × 0.3 mm × 0.3 mm - Enables placement within 2 mm of USB-C or microSD connectors. |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, ultra-small surface-mount package with 2 terminals, 0.4 mm pitch, and 0.3 mm profile - optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Anode connects to protected line; cathode ties to ground - forms first half of bidirectional clamp path. |
| 2 | Cathode (Diode 2) | Anode connects to protected line; cathode ties to ground - completes symmetrical clamp for negative transients. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping architecture | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 4.6 V clamping at 16 A TLP | Reduces stress on downstream 3.3 V I/O cells beyond standard TVS diodes with >6 V clamping. |
| 0.3 mm height | Permits integration beneath thin bezels or stacked FPC connectors in smartphones and wearables. |
| 32.5 pF capacitance | Preserves rise/fall time integrity on 480 Mbps USB 2.0 signals with <0.5% jitter impact. |
Applications
| USB 2.0 Data Lines | HDMI DDC/CEC Channels |
|---|---|
Use Scenario: Protection of differential D+ and D− lines in smartphone USB-C receptacles exposed to repeated pocket discharge events. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector pad to limit ESD-induced latch-up in USB PHY transceivers. Use Value: 4.6 V clamping prevents overvoltage damage to 3.3 V tolerant PHY inputs while maintaining <33 pF loading for full-speed signaling compliance. |
Use Scenario: ESD hardening of HDMI DDC (I²C) and CEC control lines in portable projectors and docking stations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp ensuring I²C clock/data integrity during hot-plug insertion and static discharge. Use Value: 1 nA leakage avoids pull-up current error on 4.7 kΩ I²C bus resistors; 32.5 pF supports 100 kHz timing margins with margin. |
| MIPI D-PHY Lanes | Audio Jack Sense Lines |
Use Scenario: Transient suppression on high-speed MIPI camera or display data lanes in foldable tablets where flex cable routing increases ESD risk. IC Role / Device Role / Timing Role: Signal-line protector placed adjacent to image sensor or display driver IC bond pads to minimize inductance in clamping path. Use Value: 0.3 mm height allows co-placement with 0201 decoupling caps; 5.6 V clamping at 20 A meets MIPI v2.1 surge immunity requirements. |
Use Scenario: Polarity-agnostic protection of 3.5 mm audio jack detection lines that switch between ground and VDD during plug insertion. IC Role / Device Role / Timing Role: Dual-cathode diode providing symmetric clamping regardless of jack sense voltage polarity relative to system ground. Use Value: Snap-back trigger at 7.3 V ensures clean turn-on without false triggering during normal 0–3.3 V jack state transitions. |
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 NUP4105MR6T1G | Higher clamping: 8.5 V at 24 A; larger SOT-563 package (1.6 × 1.2 × 0.95 mm); 55 pF capacitance. | Acceptable for lower-speed UART or GPIO lines but unsuitable for USB 2.0 due to capacitance and height. | Select when board space allows larger footprint and signal bandwidth <100 Mbps. |
| Vishay VEML3020X01 | Unidirectional only; 3.3 V standoff; 5.5 V clamping at 16 A; 15 pF; SC-70 package (2.0 × 1.25 × 0.9 mm). | Requires two devices for bidirectional coverage; incompatible with AC-coupled or floating lines. | Choose only if line polarity is fixed and layout permits dual-device placement. |
Compared with NUP4105MR6T1G and VEML3020X01, PESD3V3L1BSF uniquely combines sub-5 V clamping, bidirectional operation, and 0.3 mm height in a 0.6 × 0.3 mm footprint - making it the sole option for space- and signal-integrity-constrained high-speed interface protection.

FAQ
What is the maximum peak pulse current rating for PESD3V3L1BSF?
The rated peak pulse current is 20 A per IEC 61000-4-5 (8/20 µs waveform), verified via average measured testing. This value reflects the highest non-destructive surge the device sustains while maintaining clamping below 5.6 V - critical for protecting USB and HDMI PHYs in consumer-grade portable devices.
Does PESD3V3L1BSF require external bias or control circuitry?
No. PESD3V3L1BSF operates passively as a snap-back diode with no external power, enable, or configuration pins. Its dual-cathode structure provides automatic bidirectional conduction above 7.3 V trigger voltage - eliminating design overhead for polarity detection or active control.
How does the 32.5 pF capacitance affect high-speed signal integrity?
At 32.5 pF, the device adds negligible loading to USB 2.0 (480 Mbps) and MIPI D-PHY (1.5 Gbps) signals when placed within 2 mm of the connector. Measured eye diagrams show <0.5% rise-time degradation and no measurable jitter increase - meeting USB-IF and MIPI Alliance signal quality thresholds.
Can PESD3V3L1BSF replace unidirectional ESD diodes in existing designs?
Yes, but only if the protected line is bidirectional or AC-coupled. Its dual-cathode configuration provides symmetrical clamping - unlike unidirectional diodes that conduct only for one polarity. Layout must retain both terminals connected to the same signal net and ground, with no series resistors or ferrites in the clamping path.
