Product details
Overview
PCMF1USB3B/C from Nexperia is a single-channel common-mode EMI filter with integrated bidirectional ESD protection for high-speed differential data lines, featuring ±20 kV IEC 61000-4-2 contact discharge rating, 8.1 GHz differential -3 dB cut-off frequency, 0.3 pF diode capacitance at 1 MHz, and 2.6 Ω max channel series resistance - deployed at USB Type-C connectors to preserve SuperSpeed signal integrity while suppressing common-mode noise.
For engineers reviewing the PCMF1USB3B/C datasheet, PCMF1USB3B/C pinout, PCMF1USB3B/C application, or PCMF1USB3B/C equivalent, this device is selected for USB 3.2 Gen 2 (10 Gbps) and HDMI 2.0 (6 Gbps) interface protection where ultra-low capacitive loading, sub-100 ps TLP dynamic resistance, and symmetric differential routing are critical design constraints.
Technical Context
The PCMF1USB3B/C integrates coupled inductors per differential pair to provide common-mode attenuation above 100 MHz while maintaining low insertion loss (< –1 dB up to 8.1 GHz) in differential mode. Its snap-back clamping structure delivers 0.22 Ω dynamic resistance under TLP stress, enabling sub-10 V clamping voltage during ±20 kV ESD events.
It uses a WLCSP5 (2-1-2) wafer-level package with separate external input and internal output terminals per line (CH1_IN+/–, CH1_OUT+/–) and dedicated channel ground (GND_CH1), ensuring controlled impedance routing and minimal parasitic coupling between protected and downstream circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±20 kV contact discharge (IEC 61000-4-2 Level 4) - protects USB/HDMI lines against human-body-model ESD without signal degradation |
| Differential f-3dB | 8.1 GHz - supports full bandwidth of USB 3.2 Gen 2 (10 Gbps) and HDMI 2.0 (6 Gbps) without eye closure |
| Diode Capacitance | 0.3 pF @ 1 MHz, 2.5 V - minimizes signal distortion and timing skew on high-speed differential pairs |
| Channel Series Resistance | ≤2.6 Ω per line - limits DC voltage drop and power loss in battery-powered portable devices |
| Common-Mode Attenuation | ≥30 dB @ 1 GHz - suppresses RF noise coupling into adjacent traces or antennas in compact mobile PCBs |
| Dynamic Resistance (TLP) | 0.22 Ω (positive/negative transient) - ensures rapid clamping and low residual voltage during fast ESD pulses |
| Breakdown Voltage | 6–9 V @ 1 mA - provides robust overvoltage margin above 3.3 V/5 V interface rails while avoiding false triggering |
Pinout & Package
PCMF1USB3B/C uses a WLCSP5 (2-1-2) wafer-level chip-scale package measuring 0.82 mm × 1.22 mm × 0.42 mm (max height), with 5 solder bumps arranged in two outer rows (A1, A2, C1, C2) and one center bump (B1) for channel-specific grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | CH1_IN+ | External-side positive input of differential channel 1 - connects directly to USB 3.2 TX/RX+ trace at connector |
| A2 | CH1_IN– | External-side negative input of differential channel 1 - routed with matched length and spacing to A1 |
| B1 | GND_CH1 | Dedicated channel ground - isolated from system GND to prevent common-mode noise injection into protected path |
| C1 | CH1_OUT+ | Internal-side positive output - connects to SoC or controller differential receiver with controlled 85–105 Ω impedance |
| C2 | CH1_OUT– | Internal-side negative output - maintains symmetry with C1 to preserve differential signal fidelity |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Common-Mode Filter + ESD Protection | Single-die solution eliminates discrete LC filters and TVS arrays - reduces BOM count and PCB area by >40% vs. discrete alternatives |
| Ultra-High Symmetry | Matched trace lengths and coupling ensure <0.1 ps inter-line skew - critical for 10 Gbps USB 3.2 eye compliance |
| Wafer-Level Chip-Scale Packaging | WLCSP5 footprint (0.82 × 1.22 mm) enables placement within 1 mm of USB Type-C receptacle - minimizing unprotected trace length |
| Low Dynamic Clamping Resistance | 0.22 Ω TLP resistance enables <8 V clamping at 5 A peak current - prevents latch-up or damage to downstream PHYs |
| Wide Common-Mode Suppression Band | ≥30 dB attenuation from 500 MHz to 6 GHz - mitigates radiated emissions from high-speed interfaces in FCC/CE testing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar common-mode EMI filtering with integrated ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | 4-channel, 0.5 pF diode capacitance, 10.5 GHz f-3dB, SOT-563 package (1.6 × 1.6 mm) | Higher channel count but larger footprint; less suitable for space-constrained USB-C port layouts | Select when protecting multiple interfaces simultaneously and board area permits larger package |
| EMIF06-USB03F3 | 6-channel, 0.7 pF capacitance, 5 GHz f-3dB, 2.0 × 1.6 mm DFN | Lower bandwidth and higher capacitance - marginal for 10 Gbps USB 3.2 eye compliance | Acceptable only for USB 2.0 or HDMI 1.4 designs where cost is prioritized over Gen 2 performance |
Compared with TPD4E05U06DQAR and EMIF06-USB03F3, PCMF1USB3B/C offers superior high-frequency signal fidelity (8.1 GHz bandwidth, 0.3 pF) in the smallest footprint (WLCSP5), making it optimal for next-generation USB-C and HDMI 2.0 endpoints where layout density and 10 Gbps integrity are non-negotiable.

FAQ
What is the maximum recommended trace length between PCMF1USB3B/C and the USB Type-C connector?
The device must be placed within 1 mm of the USB Type-C connector's differential pins to minimize unprotected trace length. Longer traces increase common-mode coupling and degrade ESD protection effectiveness, especially above 1 GHz. Layout guidelines specify direct routing from A1/A2 to connector pins with no vias or stubs.
Can PCMF1USB3B/C be used for USB 2.0 differential pairs?
Yes - its 8.1 GHz bandwidth and low 0.3 pF capacitance fully support USB 2.0 (480 Mbps) with negligible signal impact. However, its optimized common-mode rejection and ESD rating make it over-specified for USB 2.0-only applications; lower-cost alternatives like PUSB3FR4 may be preferred unless co-location with USB 3.x is required.
Does PCMF1USB3B/C require external biasing or control signals?
No - it is a passive, unpowered device. No external voltage, current, or enable signals are needed. It operates transparently in-circuit: differential signals pass through with minimal loss, while common-mode noise and ESD transients are shunted to GND_CH1 via integrated diodes and inductive coupling.
How does the snap-back clamping behavior affect system reliability during repeated ESD events?
The snap-back structure lowers clamping voltage dynamically but requires the ESD pulse energy to remain below 10 mJ to avoid thermal runaway. Nexperia specifies ≤9.5 A peak-pulse current (8/20 μs) - staying within this limit ensures no degradation after ≥1000 ESD strikes, validated per IEC 61000-4-2.
