Product details
Overview
IP4369CX4YL from Nexperia is a 4-channel ESD protection diode array in WLCSP4 package, designed for high-speed differential interfaces including HDMI, USB 2.0 (480 Mbit/s), DisplayPort, eSATA, and LVDS. It delivers ±8 kV IEC 61000-4-2 contact ESD protection with ultra-low 0.8 pF typical line capacitance per channel and 0.4 pF inter-channel capacitance, enabling signal integrity preservation in mobile handset and portable device port protection.
For engineers reviewing the IP4369CX4YL datasheet, IP4369CX4YL pinout, IP4369CX4YL application, or IP4369CX4YL equivalent, key selection criteria include sub-1 pF capacitance, rail-to-rail clamping architecture, 2×2 WLCSP footprint (<500 µm height), and verified USB 2.0 eye diagram performance with minimal distortion.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance-0.24 Ω (positive transient) and 0.21 Ω (negative transient)-to suppress clamping voltage to +4 V / −3 V at 4–5 A surge current per IEC 61000-4-5. Its low capacitance matching (≤0.05 pF between signal pairs) ensures minimal skew in differential signaling paths.
The integrated rail-to-rail diode configuration protects both signal lines and ground reference simultaneously, supporting bidirectional ESD transients without external biasing. All four terminals are configured as two protected channels (A1/A2 signal pair, B1/B2 ground return), validated for operation across −30 °C to +85 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±8 kV contact discharge per IEC 61000-4-2 Level 4 - ensures robust system-level immunity in handheld device ports |
| Line Capacitance | 0.8 pF typical per channel at 1 MHz - preserves signal integrity up to USB 2.0 high-speed (480 Mbit/s) |
| Inter-Pair Capacitance | 0.4 pF typical - minimizes crosstalk-induced jitter in differential interfaces like HDMI and LVDS |
| Clamping Voltage | +4 V at +4 A / −3 V at −5 A per IEC 61000-4-5 - limits downstream IC stress during surge events |
| Dynamic Resistance | 0.21–0.24 Ω (TLP, 100 ns) - enables rapid voltage collapse during ESD snap-back for effective protection |
| Package Dimensions | 0.76 mm × 0.76 mm × <0.5 mm WLCSP4 (2×2 bumps, 0.4 mm pitch) - supports ultra-dense PCB layouts in smartphones |
| Operating Temperature | −30 °C to +85 °C - qualified for consumer portable electronics thermal environments |
Pinout & Package

| NSMD PCB pad recommendation | Specifies 250 µm copper pads with 100 µm laser micro-vias to minimize ground loop inductance below 0.3 nH |
| Ultra-thin profile | Height <500 µm allows integration beneath display modules or under battery compartments in slim mobile designs |
Applications
| USB 2.0 High-Speed Port Protection | HDMI Interface Receiver Protection |
|---|---|
|
Use Scenario: Protecting micro-USB receptacles in smartphones against user-handling ESD during cable insertion/removal. IC Role / Device Role / Timing Role: Bidirectional ESD clamp placed directly at connector, before USB PHY transceiver. Use Value: Maintains 480 Mbit/s eye diagram integrity (Fig 7) while suppressing ±8 kV transients to <±4 V clamping level. |
Use Scenario: Shielding HDMI Type-D (micro-HDMI) ports in tablets from ESD during docking/undocking. IC Role / Device Role / Timing Role: Differential pair protector on TMDS clock/data lanes, referenced to local ground plane. Use Value: 0.4 pF inter-pair capacitance prevents skew-induced jitter; 0.8 pF per-line capacitance avoids bandwidth roll-off above 1 GHz. |
| eSATA Connector Protection | LVDS Camera Interface Protection |
|

IC Role / Device Role / Timing Role: Single-ended ESD clamp on TX/RX lines, with dedicated ground return (B1/B2) routed to chassis ground. Use Value: 0.21 Ω dynamic resistance ensures fast clamping response (<1 ns), limiting voltage overshoot during 30 A surge pulses. |
Use Scenario: Securing high-speed MIPI D-PHY camera links in foldable phone hinge zones prone to repeated flex-induced ESD. IC Role / Device Role / Timing Role: Dual-channel protector applied to LP/HS lane pairs, leveraging matched capacitance for common-mode noise rejection. Use Value: ≤0.05 pF capacitance mismatch preserves differential skew budget under 10 ps, meeting MIPI D-PHY v2.1 timing requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DQAR (TI) | 0.6 pF line capacitance, SOT-5X3 package (1.45 mm × 1.0 mm), higher 1.2 mm height | Preferred for space-constrained but height-tolerant designs; lacks WLCSP miniaturization | Select when board assembly favors SMT placement over WLCSP reflow and ground inductance is less critical |
| ESD56084D05 (ON Semi) | 0.5 pF capacitance, 4-channel WLCSP but 0.5 mm pitch (vs. 0.4 mm), 0.65 mm × 0.65 mm footprint | Suitable for mid-tier portable devices where 0.1 mm pitch reduction is non-essential | Choose when existing PCB stencil supports 0.5 mm pitch and lower capacitance justifies larger die area |
Compared with TPD4E001DQAR and ESD56084D05, IP4369CX4YL offers the smallest footprint (0.76 mm²) and tightest capacitance matching (≤0.05 pF), making it optimal for flagship smartphone front-panel interface protection where board real estate and signal fidelity are paramount.

FAQ
What is the maximum recommended PCB trace length between IP4369CX4YL and the protected connector?
Trace length should not exceed 3 mm from device solder bump to connector pin to maintain low-inductance ESD current path. Longer traces increase ground loop inductance, degrading clamping response and risking voltage overshoot beyond the ±4 V/−3 V spec. Use direct micro-via connections to inner ground planes as specified in Nexperia's PCB design guidelines.
Can IP4369CX4YL be used for USB 3.0 or PCIe Gen2 interfaces?
No-IP4369CX4YL is characterized only up to 1 GHz (validated for USB 2.0's 240 MHz fundamental), and its 0.8 pF capacitance causes unacceptable insertion loss above 2 GHz. USB 3.0 and PCIe Gen2 require sub-0.3 pF protectors such as Nexperia's PESD5V0S1BA or TI's TPD6S300A.
Is external decoupling capacitance required at the B1/B2 ground terminals?
No external capacitor is needed or recommended. The device relies on low-inductance PCB ground plane coupling via micro-vias. Adding discrete capacitors introduces parasitic inductance that compromises high-frequency ESD current shunting. Follow Nexperia's NSMD pad and buried ground plane recommendations instead.
Does IP4369CX4YL support hot-plug detection in USB OTG applications?
IP4369CX4YL does not implement any logic or sensing function-it is a passive clamping diode array. Hot-plug detection remains handled by the USB PHY or controller IC. The device only provides ESD robustness during plug/unplug events, with no impact on ID pin detection or VBUS monitoring circuitry.
