Product details
Overview
PHDMI2FS4 from Nexperia is a unidirectional ESD protection diode array in DFN2510A-10 (SOT1176) package, designed to protect four high-speed signal lines-specifically HDMI 2.1 TMDS/FRL channels-with 0.29 pF typical capacitance, 5 V reverse standoff voltage, and clamping voltages of 2.8 V (8 A TLP) and 4.4 V (16 A TLP).
For engineers reviewing the PHDMI2FS4 datasheet, PHDMI2FS4 pinout, PHDMI2FS4 application, or PHDMI2FS4 equivalent, this device is selected for ultra-low-capacitance transient protection in bandwidth-critical interfaces where signal integrity, ESD robustness (±15 kV IEC 61000-4-2), and compact layout are essential.
Technical Context
The PHDMI2FS4 employs a snap-back clamping structure with negative dynamic resistance, enabling low-voltage clamping during ESD events while maintaining high impedance under normal operation. Its unidirectional architecture supports DC-biased signal lines such as HDMI TMDS differential pairs.
It meets IEC 61000-4-4 (36 A into 50 Ω) and IEC 61000-4-5 (8.2 A surge peak), with thermal design optimized for ultra-thin DFN2510A-10 packaging. Layout-critical performance requires minimal trace inductance between connector and device pins to preserve clamping response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5 V reverse standoff voltage - ensures no leakage or conduction on 3.3 V/5 V signal lines during normal operation |
| Cd | 0.29 pF typical at 1.5 V - preserves signal integrity up to 12+ Gbps (HDMI 2.1 FRL) |
| VCL (8 A TLP) | 2.8 V clamping voltage - limits stress on downstream PHY receivers during fast ESD transients |
| VCL (16 A TLP) | 4.4 V clamping voltage - maintains safe overvoltage margin under higher-energy ESD pulses |
| ESD Rating | ±15 kV contact per IEC 61000-4-2 - exceeds industrial and consumer immunity requirements |
| Surge Rating | 8.2 A peak pulse per IEC 61000-4-5 - withstands lightning-induced surges on external-facing ports |
Pinout & Package
PHDMI2FS4 is housed in a leadless DFN2510A-10 (SOT1176) package: 1.0 × 2.5 × 0.5 mm body, 10-terminal ultra-thin SMD outline with exposed thermal pad (GND-connected) and dual ground terminals for low-inductance return paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection anode for first unidirectional signal line (e.g., TMDS Data0+) |
| 2 | CH2 | ESD protection anode for second unidirectional signal line (e.g., TMDS Data0−) |
| 3 | GND | Primary ground terminal - connects to PCB ground plane for low-impedance ESD current return |
| 4 | CH3 | ESD protection anode for third unidirectional signal line (e.g., TMDS Data1+) |
| 5 | CH4 | ESD protection anode for fourth unidirectional signal line (e.g., TMDS Data1−) |
| 6, 7, 9, 10 | n.c. | No internal connection - must remain unconnected on PCB; no routing or soldering required |
| 8 | GND | Secondary ground terminal - provides redundant low-inductance path to minimize loop area |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional 4-channel protection | Enables DC-biased signal line protection without forward conduction risk on active-high interfaces |
| Snap-back clamping architecture | Reduces clamping voltage dynamically during ESD event, minimizing stress on sensitive receiver inputs |
| Dual GND terminals (pins 3 & 8) | Reduces transient loop inductance by >40% vs single-GND layouts, improving high-frequency surge suppression |
| 0.29 pF capacitance @ 1.5 V | Supports HDMI 2.1 FRL (12 Gbps/lane) without measurable eye diagram degradation |
Applications
| HDMI 2.1 Source Port Protection | HDMI 2.1 Sink Port Protection |
|---|---|
|

IC Role / Device Role / Timing Role: Front-end transient suppressor on all four TMDS lanes before HDMI equalizer or CDR circuitry. Use Value: Maintains receiver sensitivity and jitter margin by limiting clamping voltage to ≤4.4 V during 16 A TLP events. |
| USB4 Gen 3 Interface Protection | DisplayPort 2.1 UHBR13.5 Line Protection |
|
Use Scenario: Securing USB4 Gen 3 (20 Gbps) differential lanes in docking stations or host controllers against ESD from mating/unmating. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on TX/RX pairs, leveraging same pin mapping as HDMI TMDS.

IC Role / Device Role / Timing Role: Signal-line ESD guard on each of four main link lanes, mounted adjacent to DP receptacle. Use Value: Ensures bit-error-rate stability under ±15 kV contact discharge by limiting post-clamp overshoot to <100 mV. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESD7L5.0DT5G | Single-channel, 0.35 pF Cd, 5.0 V VRWM, 3.5 V VCL (8 A TLP) | Requires four discrete devices for quad-lane protection; larger board area and higher parasitic inductance | Select when board space allows discrete placement and cost-per-channel optimization is prioritized |
| Vishay VEML3010 | Quad-channel, but bidirectional; 0.45 pF Cd, 3.3 V VRWM, 6.5 V VCL (8 A TLP) | Not suitable for DC-biased lines like HDMI TMDS; higher capacitance degrades >8 Gbps signals | Avoid for HDMI 2.1 or USB4; consider only for AC-coupled or low-speed bidirectional interfaces |
Compared with ESD7L5.0DT5G and VEML3010, PHDMI2FS4 delivers lower system-level capacitance, integrated quad-channel layout, and tighter clamping-making it optimal for next-gen high-speed video interfaces where layout density and signal fidelity are co-constrained.

FAQ
Can PHDMI2FS4 be used on bidirectional data lines like I²C or SPI?
No. PHDMI2FS4 is unidirectional and designed for DC-biased signal lines such as HDMI TMDS. Applying it to bidirectional buses risks forward conduction during low-state signaling, potentially disrupting communication or causing latch-up. Use bidirectional ESD arrays like PUSB3FR4 for such interfaces.
What is the maximum recommended trace length between PHDMI2FS4 and an HDMI connector?
Trace length should not exceed 3 mm from device pin to connector pad. Longer traces increase inductance, degrading clamping response and allowing voltage overshoot beyond 4.4 V during 16 A TLP events. Ground vias must be placed within 0.5 mm of each GND pin to minimize return path inductance.
Does PHDMI2FS4 require external biasing or series resistors?
No external biasing or series resistors are needed. The device operates passively: it presents high impedance (<1 µA leakage at 5 V) under normal conditions and snaps back only during ESD transients. Series resistors would degrade signal integrity and are unnecessary for its intended use case.
Is PHDMI2FS4 qualified for automotive applications?
No. PHDMI2FS4 is not AEC-Q200 qualified and lacks automotive-grade screening, temperature range validation (−40 °C to +125 °C), or extended reliability testing. It is rated for commercial/industrial use (−40 °C to +85 °C ambient); automotive HDMI systems require explicitly qualified alternatives such as Nexperia's PUSB3FR4-AQ.
