Product details
Overview
PHDMI2F4 from Nexperia is a four-channel ESD protection diode array designed specifically for HDMI 2.0 and earlier TMDS differential signal lines. It delivers ±10 kV contact ESD protection per IEC 61000-4-2 Level 4, features ultra-low 0.5 pF line capacitance per channel, matched 0.05 pF inter-pair capacitance, and uses snap-back clamping to achieve low clamping voltage (4.6 V positive / −2.2 V negative at 5.2 A/−4.4 A). It is deployed inline on HDMI source/receiver ports in consumer AV equipment.
For engineers reviewing the PHDMI2F4 datasheet, PHDMI2F4 pinout, PHDMI2F4 application, or PHDMI2F4 equivalent, this device is selected for high-speed interface protection where sub-0.6 pF capacitance, rail-to-rail clamping, and HDMI 2.0-compliant eye diagram integrity (2160p/60 Hz) are mandatory design requirements.
Technical Context
The PHDMI2F4 implements four independent snap-back ESD clamps - one per TMDS channel - with negative dynamic resistance behavior that reduces clamping voltage during transient events. Each channel provides bidirectional rail-to-rail clamping between VCC and GND, with breakdown voltage ≥6 V and dynamic resistance as low as 0.26 Ω (negative transient).
Its DFN2510A-10 package enables 0.5 mm trace spacing compatibility and pass-through routing, minimizing PCB layout disruption. Signal integrity is preserved via matched capacitance (≤0.05 pF difference between pairs) and insertion loss <−2 dB up to 10 GHz, validated by HDMI 2.0 TP1/TP2 eye diagrams with and without the device.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±10 kV contact discharge (IEC 61000-4-2 Level 4); ensures robust system-level immunity against human-body model discharges. |
| Line Capacitance | 0.5 pF typical per channel at 1 MHz/3.3 V; preserves HDMI 2.0 signal integrity by minimizing high-frequency attenuation. |
| Capacitance Matching | ≤0.05 pF difference between differential pairs; maintains common-mode rejection and skew control across TMDS lanes. |
| Clamping Voltage | +4.6 V / −2.2 V at 5.2 A / −4.4 A (IEC 61000-4-5); limits downstream IC stress below HDMI receiver absolute max ratings. |
| Breakdown Voltage | ≥6 V at 1 mA; guarantees no conduction during normal 3.3 V TMDS operation while enabling fast ESD response. |
| Dynamic Resistance | 0.26 Ω (negative transient), 0.41 Ω (positive transient); sustains low-voltage clamping under high-current ESD pulses. |
Pinout & Package
PHDMI2F4 is housed in a leadless DFN2510A-10 (SOT1176-1) package measuring 2.5 × 1.0 × 0.5 mm with exposed thermal pad. The package supports reflow soldering using a 75 μm stencil and provides two GND pins (pins 3 and 8) for low-inductance return paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection input/output for TMDS channel 1 (e.g., D0+) |
| 2 | CH2 | ESD protection input/output for TMDS channel 2 (e.g., D0−) |
| 3 | GND | Primary ground reference for clamping diodes; connects to PCB ground plane |
| 4 | CH3 | ESD protection input/output for TMDS channel 3 (e.g., D1+) |
| 5 | CH4 | ESD protection input/output for TMDS channel 4 (e.g., D1−) |
| 6, 7, 9, 10 | n.c. | No internal connection; must be left floating or grounded per layout best practice |
| 8 | GND | Secondary ground terminal; improves thermal dissipation and reduces ground loop inductance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail clamping architecture | Clamps signals between VCC and GND without external bias, eliminating need for pull-up resistors or auxiliary supply rails. |
| Snap-back trigger mechanism | Reduces clamping voltage by >30% vs. standard diodes during ESD transients, protecting sensitive HDMI PHY receivers. |
| Matched 0.5 mm trace pitch | Aligns with standard HDMI PCB stackup; enables direct in-line placement without layer transitions or vias. |
| Pass-through signal routing | Input and output pins are aligned linearly (1–2–3–4–5), allowing straight trace runs and preserving differential impedance continuity. |
| Ultra-low inter-pair capacitance mismatch | ≤0.05 pF difference ensures <1 ps skew between differential pairs, critical for HDMI 2.0 timing margin. |
Applications
| TV and Monitor HDMI Inputs | DVD/Blu-ray Player Outputs |
|---|---|
|
Use Scenario: Protecting HDMI receiver ports on flat-panel TVs and monitors against ESD during cable insertion or handling. IC Role / Device Role / Timing Role: In-line bidirectional ESD clamp on all four TMDS differential pairs, placed immediately before the HDMI connector. Use Value: Maintains HDMI 2.0 eye opening (2160p/60 Hz) while suppressing ±10 kV contact discharges - verified by TP1/TP2 eye diagrams with/without device. |
Use Scenario: Securing HDMI transmitter outputs on DVD recorders and Blu-ray players against user-induced ESD events. IC Role / Device Role / Timing Role: Front-end ESD guard for TMDS lanes driving external cables; operates at 3.3 V nominal signaling. Use Value: Enables compliance with IEC 61000-4-2 Level 4 without degrading signal rise/fall times (<34 ps/div measured) or introducing measurable jitter. |
| Notebook GPU Output Ports | Set-Top Box HDMI Interfaces |
|
Use Scenario: Integrating ESD protection into compact notebook motherboard layouts where space and signal integrity are constrained. IC Role / Device Role / Timing Role: Four-channel discrete ESD solution replacing multiple single-diode packages; occupies only 2.5 × 1.0 mm PCB area. Use Value: Reduces BOM count and layout complexity while delivering 0.5 pF/channel capacitance - critical for maintaining 6 GHz bandwidth in mobile GPU interfaces. |
Use Scenario: Hardening HDMI ports on set-top boxes and game consoles subjected to frequent hot-plug cycles and environmental ESD. IC Role / Device Role / Timing Role: System-level ESD barrier between connector and SoC HDMI PHY; supports hot-plug detection line integrity. Use Value: Prevents latch-up or permanent damage to HDMI controller ICs during field use, with validated operation from −40 °C to +85 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar HDMI ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IP4221CZ6 | Single-channel, 0.35 pF capacitance, ±8 kV contact rating; requires four devices for full HDMI protection. | Higher component count and larger footprint; less optimal for space-constrained designs. | Prefer PHDMI2F4 when board area and assembly cost are critical; IP4221CZ6 suits designs needing per-lane tuning. |
| SP1002-04UTG | Four-channel, 0.3 pF capacitance, ±12 kV contact rating; uses different snap-back topology with higher dynamic resistance (0.6 Ω). | Better ESD margin but higher clamping voltage (5.2 V) risks violating HDMI receiver VIH/VIL limits. | Choose SP1002-04UTG only if system-level testing confirms clamping voltage compatibility; PHDMI2F4 offers tighter voltage control. |
Compared with IP4221CZ6 and SP1002-04UTG, PHDMI2F4 uniquely balances ultra-low capacitance (0.5 pF), precise clamping (4.6 V/−2.2 V), and integrated four-channel packaging - making it optimal for HDMI 2.0 designs requiring minimal signal distortion and guaranteed IEC 61000-4-2 Level 4 compliance.

FAQ
Can PHDMI2F4 be used for HDMI 2.1 interfaces?
No. PHDMI2F4 is characterized and qualified for HDMI 2.0 and earlier standards only. HDMI 2.1 requires higher bandwidth (up to 48 Gbps), lower capacitance (<0.3 pF), and stricter insertion loss performance - which PHDMI2F4 does not meet. Its electrical validation stops at 148.5 MHz (2160p/60 Hz), well below HDMI 2.1's 12 GHz TMDS clock requirement.
Is external bias required for PHDMI2F4 operation?
No external bias is needed. PHDMI2F4 uses a passive rail-to-rail clamping structure that operates between the TMDS signal lines and local GND/VCC. It functions correctly with standard 3.3 V HDMI signaling and does not require connection to a dedicated VCC rail - simplifying layout and reducing BOM count.
What is the maximum recommended trace length between PHDMI2F4 and HDMI connector?
Trace length should be minimized - ideally ≤3 mm - to maintain impedance continuity and avoid stub effects. Longer traces increase inductance, degrading ESD response time and insertion loss. The device's pass-through pinout (1–2–3–4–5) supports direct in-line routing, and its 0.5 mm pitch matches standard HDMI differential pair spacing to eliminate need for fan-out vias.
Does PHDMI2F4 support hot-plug detection (HPD) line protection?
No. PHDMI2F4 protects only the four TMDS differential channels (CH1–CH4). HPD, DDC_CLK, and DDC_DAT lines require separate protection - typically a low-capacitance unidirectional TVS like PESD5V0S1BA. The datasheet application diagram (Fig 13) explicitly shows PHDMI2F4 placed only on TMDS lanes, with HPD routed separately through a different protection device.
