Product details

Overview

PCMF1USB3S/CZ 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 per line - enabling clean signal integrity in USB 3.2 SuperSpeed (10 Gbps) and HDMI 2.0 applications.

For engineers reviewing the PCMF1USB3S/CZ datasheet, PCMF1USB3S/CZ pinout, PCMF1USB3S/CZ application, or PCMF1USB3S/CZ equivalent, key selection criteria include differential impedance preservation (Z_dif ≈ 90 Ω), channel symmetry (<±0.1 ps skew), low dynamic resistance (0.14 Ω TLP positive/negative), and WLCSP5 footprint compatibility with USB Type-C connector-level placement.

Technical Context

This device integrates coupled inductors for common-mode rejection and bidirectional ESD clamping diodes on each signal line, operating as a passive front-end filter between external connectors and IC transceivers. Its architecture maintains differential signal fidelity while suppressing RF noise above 800 MHz and diverting ESD transients away from sensitive PHY circuitry.

The WLCSP5 package uses a 2-1-2 bump layout with dedicated input/output pairs and isolated channel ground (B1), enabling direct routing from USB Type-C receptacle pins to SoC without stubs or vias. The snap-back clamping behavior reduces clamping voltage during ESD events but requires avoidance of DC bias beyond 5 V to prevent latch-up.

Key Specifications

Parameter	Value and Actual Design Meaning
Channels	1 differential channel (CH1_IN+/CH1_IN− → CH1_OUT+/CH1_OUT−)
ESD Protection	±15 kV contact discharge per line (IEC 61000-4-2 Level 4)
Differential Insertion Loss	0.3 dB at 1 MHz; −18 dB at 5 GHz - preserves eye opening up to 10 Gbps
Common-Mode Attenuation	−12 dB at 800 MHz; −38 dB at 2.6 GHz - suppresses radiated emissions
Diode Capacitance	0.25 pF at 1 MHz, 2.5 V - minimizes signal loading on USB 3.2/HDMI 2.0 lines
Channel Series Resistance	3 Ω per line (input to output) - limits DC voltage drop under 100 mA operation
Breakdown Voltage	6–9 V (IR = 1 mA) - ensures clamping activates before downstream PHY damage

Pinout & Package

PCMF1USB3S/CZ is housed in a WLCSP5 wafer-level chip-scale package (2-1-2 bump configuration, 0.80 mm × 0.80 mm, 0.40 mm pitch), optimized for minimal PCB area and high-frequency performance near USB Type-C connectors.

Pin/Terminal	Circuit Role	Design Meaning
A1	CH1_IN+	External differential input + (connects directly to USB 3.2 TX/RX+ from connector)
A2	CH1_IN−	External differential input − (connects directly to USB 3.2 TX/RX− from connector)
B1	GND_CH1	Isolated channel ground - must be tied to local shield/connector ground, not system GND plane
C1	CH1_OUT+	Internal differential output + (routes to SoC PHY differential receiver)
C2	CH1_OUT−	Internal differential output − (routes to SoC PHY differential receiver)

Key Features

Feature	Design Value
Integrated Common-Mode Filter + ESD Clamp	Single-component solution replaces discrete LC filters + TVS arrays - eliminates layout mismatch and parasitic coupling
Ultra-Low Diode Capacitance	0.25 pF enables <1% signal distortion at 5 GHz - critical for HDMI 2.0 and USB 3.2 eye compliance
High Symmetry Between Line Pairs	Sub-0.1 ps inter-line skew preserves differential timing margin in 10 Gbps links
WLCSP5 Footprint	0.80 mm × 0.80 mm area with 0.40 mm pitch - fits within USB Type-C connector keep-out zone
Snap-Back Clamping Structure	Dynamic resistance of 0.14 Ω (TLP) reduces clamping voltage to <12 V during ±15 kV ESD - protects 1.2 V/1.8 V PHY I/O

Equivalent & Alternatives

The following parts are listed as comparable options for similar common-mode EMI + ESD protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDK MEM2012W121RT001	120 Ω @ 100 MHz common-mode impedance; no integrated ESD diodes - requires external TVS	Higher insertion loss (>0.8 dB at 5 GHz); larger 0805 footprint; needs separate ESD component	Choose only if board space allows discrete implementation and ESD requirements are ≤±8 kV
ON Semiconductor NUF2221MUTAG	Two-channel device in UDFN-8; 0.5 pF diode capacitance; ±12 kV ESD rating	Not pin-compatible; higher capacitance degrades 10 Gbps eye; unsuitable for USB 3.2 Gen 2	Select only for lower-speed USB 2.0 or MIPI D-PHY ≤1.2 Gbps where capacitance tolerance is relaxed

Compared with TDk MEM2012W121RT001 and ON Semi NUF2221MUTAG, PCMF1USB3S/CZ delivers superior high-frequency EMI suppression, lower signal loading, and true single-chip ±15 kV protection - making it the only qualified option for USB 3.2 Gen 2 and HDMI 2.0 certified designs requiring minimal footprint and guaranteed eye integrity.

FAQ

What is the maximum recommended DC bias voltage for PCMF1USB3S/CZ?

The absolute maximum input voltage is −0.5 V to +5 V per pin. Exceeding 5 V risks triggering the snap-back clamping structure into sustained conduction, potentially damaging the device or downstream circuitry. For USB 3.2 and HDMI 2.0 applications, the nominal 0–3.3 V signaling range remains safely within this limit.

Can PCMF1USB3S/CZ be used for USB 2.0 differential pairs?

Yes - its 0.3 dB insertion loss at 1 MHz and <0.25 pF capacitance ensure negligible impact on USB 2.0's 480 Mbps signaling. However, its full value lies in protecting higher-speed interfaces; for USB 2.0-only designs, lower-cost alternatives like PESD5V0S1BA may be more economical.

How should the GND_CH1 (B1) pin be connected on the PCB?

B1 must be connected to a local, low-inductance ground plane near the USB Type-C connector - not daisy-chained to system ground. This isolation prevents common-mode noise coupling into the protected channel and maintains the filter's specified 2.6 GHz attenuation performance.

Does PCMF1USB3S/CZ require external decoupling capacitors?

No - the device contains no active circuitry and does not require power or bypass capacitors. Its operation relies solely on passive LC filtering and diode clamping. PCB design must prioritize controlled-impedance routing (90 Ω differential) and minimize via stubs between A1/A2 and C1/C2 traces.
