Product details
Overview
PCMF1USB30Z from Nexperia is a single-channel common-mode EMI filter with integrated ±15 kV IEC 61000-4-2 ESD protection for high-speed differential interfaces. It features 0.3 dB differential insertion loss at 1 MHz, −38 dB common-mode attenuation at 2.6 GHz, and 0.25 pF diode capacitance at 1 MHz/2.5 V - enabling USB 3.1 Gen 1 (5 Gbit/s) signal integrity preservation while suppressing RF noise in smartphone and tablet USB Type-C connector protection.
For engineers reviewing the PCMF1USB30Z datasheet, PCMF1USB30Z pinout, PCMF1USB30Z application, or PCMF1USB30Z equivalent, key selection criteria include differential channel count (1), WLCSP5 package footprint (0.82 × 1.22 mm), ESD clamping voltage under TLP (0.14 Ω dynamic resistance), and common-mode rejection bandwidth (6 GHz cutoff).
Technical Context
The device integrates coupled inductors per differential pair to suppress common-mode noise without degrading differential signal integrity, while low-capacitance ESD diodes (0.25 pF) minimize signal distortion on SuperSpeed TX/RX lines. Its snapback clamping structure reduces clamping voltage during ESD transients, achieving 0.14 Ω dynamic resistance under positive/negative TLP pulses.
Designed for placement directly at USB Type-C connectors, it maintains matched trace lengths and avoids ground/voltage plane discontinuities by separating Hi-Speed and SuperSpeed lines via dedicated GND_CH1. The WLCSP5 package (2-1-2 bump layout) enables ultra-compact routing with 0.4 mm pitch and 0.25 mm solder land width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Differential channels | 1 - supports full USB 3.1 Gen 1 differential pair (TX+/TX− or RX+/RX−) |
| ESD protection level | ±15 kV contact discharge (IEC 61000-4-2 Level 4) - protects downstream PHY from connector-level ESD events |
| Differential insertion loss | 0.3 dB at 1 MHz - negligible signal attenuation for low-frequency eye opening and DC balance |
| Common-mode attenuation | −38 dB at 2.6 GHz - suppresses USB 3.1 Gen 1 common-mode emissions near Nyquist frequency |
| Diode capacitance | 0.25 pF at 1 MHz/2.5 V - preserves >6 GHz differential bandwidth and minimizes jitter accumulation |
| Channel series resistance | 3 Ω per line - limits resistive loss while maintaining ESD robustness and thermal dissipation |
| Breakdown voltage | 6–9 V - ensures reliable clamping below USB 3.1 VBUS tolerance (5.25 V max) without false triggering |
Pinout & Package
PCMF1USB30Z uses a wafer-level chip-scale package (WLCSP5) with 5 bumps in 2-1-2 configuration, measuring 0.82 mm × 1.22 mm × 0.38 mm height. The package enables direct mounting adjacent to USB Type-C receptacles with minimal PCB area and no wirebond parasitics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | CH1_IN+ | External differential input + line - connects to USB 3.1 TX+/RX+ from connector |
| A2 | CH1_IN− | External differential input − line - connects to USB 3.1 TX−/RX− from connector |
| B1 | GND_CH1 | Channel-specific ground - isolated return path for ESD current, prevents coupling into system ground plane |
| C1 | CH1_OUT+ | Internal differential output + line - routes filtered signal to USB controller PHY |
| C2 | CH1_OUT− | Internal differential output − line - maintains symmetry with C1 for impedance continuity |
Key Features
| Feature | Design Value |
|---|---|
| Integrated common-mode choke + ESD diodes | Single-die solution eliminates discrete filter + TVS bill-of-materials and layout complexity |
| Ultra-low diode capacitance | 0.25 pF enables <6 GHz differential bandwidth - critical for USB 3.1 Gen 1 eye diagram compliance |
| Snapback clamping architecture | 0.14 Ω dynamic resistance under TLP reduces clamping voltage, protecting sensitive PHY inputs |
| WLCSP5 footprint | 0.82 × 1.22 mm area - fits within USB Type-C connector keep-out zone without compromising routing density |
| High symmetry between line pairs | Matched propagation delay and impedance (<0.1 ps skew) preserves differential signal integrity |

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 |
|---|---|---|---|
| TPD4E001DPYR | 4-channel, 0.5 pF diode capacitance, SOT-563 package (1.6 × 1.6 mm) | Supports multi-lane interfaces (e.g., dual USB 2.0) but larger footprint and higher capacitance limits USB 3.1 use | Select when consolidating multiple low-speed channels; avoid for >1 Gbit/s differential links due to capacitance penalty |
| IP4283CZ10 | 3-channel, 0.35 pF capacitance, XSON10 package (2.1 × 1.6 mm), lower common-mode attenuation (−25 dB @ 2.6 GHz) | Targeted at HDMI 1.4 and MIPI CSI-2, not validated for USB 3.1 Gen 1 eye compliance | Prefer for cost-sensitive HDMI 1.4 designs where 6 GHz bandwidth is unnecessary |
Compared with TPD4E001DPYR and IP4283CZ10, PCMF1USB30Z delivers superior high-frequency common-mode rejection (−38 dB @ 2.6 GHz) and lowest diode capacitance (0.25 pF) in the smallest footprint (WLCSP5), making it the only option qualified for USB 3.1 Gen 1 signal integrity requirements.

FAQ
What is the maximum data rate supported by PCMF1USB30Z?
PCMF1USB30Z supports up to 5 Gbit/s (USB 3.1 Gen 1), verified by eye diagram testing (Figs 5–8) showing compliant opening at 10 Gbit/s test conditions. Its 6 GHz differential −3 dB bandwidth and 0.25 pF diode capacitance ensure minimal intersymbol interference and jitter accumulation on SuperSpeed lanes.
Can PCMF1USB30Z be used for USB 2.0 high-speed (480 Mbps) protection?
Yes - PCMF1USB30Z is fully compatible with USB 2.0 high-speed operation. Its 0.3 dB differential insertion loss at 1 MHz and −12 dB common-mode attenuation at 800 MHz provide effective EMI filtering and ±15 kV ESD protection without degrading signal rise/fall times or eye height required for 480 Mbps compliance.
Is a separate ground connection required for optimal ESD performance?
Yes - Pin B1 (GND_CH1) must be connected to a low-inductance local ground plane adjacent to the USB connector. This dedicated channel ground provides a controlled return path for ESD current, preventing coupling into shared system ground and ensuring clamping voltage remains below 6 V during ±15 kV events.
Does PCMF1USB30Z require external biasing or control signals?
No - PCMF1USB30Z is a passive, unpowered device. It requires no external voltage, enable pins, or configuration. Operation is fully automatic: ESD clamping activates only during transients, and common-mode filtering occurs continuously via integrated coupled inductors without affecting DC or low-frequency signal content.
