Product details
Overview
PESD1USB3B/C from Nexperia is a single-channel bidirectional ESD protection diode array for high-speed differential data lines, featuring ±20 kV IEC 61000-4-2 contact discharge rating, 0.29 pF typical diode capacitance at 1 MHz, 6 V minimum breakdown voltage, and WLCSP5 (2-1-2) package. It protects USB 3.2 SuperSpeed TX/RX pairs directly at Type-C connectors while preserving signal integrity up to 16.1 GHz f-3dB.
For engineers reviewing the PESD1USB3B/C datasheet, PESD1USB3B/C pinout, PESD1USB3B/C application, or PESD1USB3B/C equivalent, key selection criteria include differential-mode insertion loss < −1 dB at 5 Gbps, dynamic resistance ≤ 0.2 Ω under TLP stress, GND-isolated channel architecture, and footprint compatibility with PCMF1USB3B/C common-mode filters.
Technical Context
The device implements a TrEOS clamping structure enabling snap-back behavior that reduces clamping voltage during ESD transients, with positive/negative dynamic resistance ≤ 0.2 Ω per line under 100 ns TLP testing. Its low-capacitance design ensures minimal signal distortion on differential pairs operating up to 10 Gbps.
It supports bidirectional protection without polarity constraints and requires no external biasing-each channel uses independent GND_CH1 reference with isolated input/output terminals (CH1_IN±/CH1_OUT±), enabling direct placement at high-speed connector interfaces while maintaining impedance continuity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential-line ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCMF1USB3B/C | Integrates common-mode filter + ESD protection in same WLCSP5 footprint; higher insertion loss (−1.8 dB @ 5 GHz) | Required where EMI filtering is mandated alongside ESD protection (e.g., FCC/CE radiated emissions compliance) | Select when board space prohibits discrete filter + ESD solution and CM noise suppression is critical |
| ESD5V3U2U | 0.5 pF capacitance; ±15 kV ESD rating; SOT323 package (1.7 × 1.25 mm) | Suitable for lower-speed interfaces (USB 2.0, LVDS) where 10 Gbps bandwidth is unnecessary | Choose for cost-sensitive designs with relaxed speed requirements and larger PCB real estate |
Compared with PCMF1USB3B/C, PESD1USB3B/C offers superior high-frequency transparency but no common-mode rejection; versus ESD5V3U2U, it delivers 3× lower capacitance and 33% higher ESD rating in 60% smaller area-making it optimal for next-gen USB/HDMI physical layer protection.

FAQ
What is the maximum recommended trace length between PESD1USB3B/C and the USB Type-C connector?
The device must be placed within 3 mm of the connector's differential pins to minimize unprotected stub length. Longer traces increase inductance, degrading ESD response time and causing reflections above 5 GHz-verified via TDR measurements showing Zdif deviation < ±5 Ω only when mounted per Fig. 18 layout guidelines.
Can PESD1USB3B/C be used on single-ended lines like USB 2.0 D+/D−?
No-it is optimized exclusively for differential signaling. Single-ended use violates its internal symmetry and raises clamping voltage beyond 12 V due to unbalanced current paths. For USB 2.0, Nexperia recommends PESD5V0S1BA or similar single-line ESD arrays with matched capacitance.
Does PESD1USB3B/C require a dedicated ground plane or can it share the main system GND?
GND_CH1 must connect to a localized, low-inductance ground pour adjacent to the protected differential pair-not the main system ground. Shared grounding introduces noise coupling and elevates clamping voltage by up to 40% during multi-pin ESD events, as confirmed in IEC 61000-4-2 system-level tests.
How does the TrEOS snap-back mechanism affect DC biasing of protected lines?
The snap-back behavior only activates during transient overvoltage (>6 V). Under normal 0–5 V signaling, leakage remains ≤1 nA. However, sustained DC >6 V will latch the device in low-resistance state-so avoid connecting battery rails or unregulated supplies directly to CH1_IN± terminals.
