Product details
Overview
PHDMI2BB4Z from Nexperia is an extremely low capacitance bidirectional ESD protection diode array in a DFN2510A-10 (SOT1176-2) package, designed to protect four high-speed signal lines-such as HDMI 2.1 and USB 3.2 data lanes-against ±15 kV IEC 61000-4-2 ESD events, with 0.17 pF typical capacitance at 1.5 V and 5.4 V clamping voltage at 6.5 A (8/20 µs).
For engineers reviewing the PHDMI2BB4Z datasheet, PHDMI2BB4Z pinout, PHDMI2BB4Z application, or PHDMI2BB4Z equivalent, this device is selected for ultra-low-capacitance transient suppression on differential high-speed interfaces where signal integrity, insertion loss, and eye diagram compliance are critical.
Technical Context
This device implements a snap-back clamping structure with negative dynamic resistance, enabling rapid transition into low-voltage conduction during ESD transients while maintaining sub-0.2 pF capacitance across all four protected channels. Its bidirectional architecture supports AC-coupled and DC-coupled signal lines without polarity constraints.
It meets IEC 61000-4-4 (40 A EFT into 50 Ω) and IEC 61000-4-5 (8.3 A surge peak), with VRWM = ±3.3 V and guaranteed operation up to 125 °C ambient. The DFN2510A-10 package provides minimal parasitic inductance and thermal resistance for PCB-level transient energy dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | ±3.3 V - Ensures no leakage or conduction during normal 3.3 V I/O operation, preserving signal swing and logic margin. |
| Cd (typ) | 0.17 pF at 1.5 V - Minimizes high-frequency loading on HDMI 2.1/USB 3.2 differential pairs, preserving >10 Gbps signal fidelity. |
| VCL @ 6.5 A | 5.4 V (8/20 µs) - Limits transient overvoltage to safe levels for downstream PHY receivers with 3.3 V absolute max ratings. |
| ESD Rating | ±15 kV IEC 61000-4-2 contact - Fully covers end-equipment user-port ESD immunity requirements per EN 61000-4-2 Level 4. |
| Surge Rating | 8.3 A peak (IEC 61000-4-5) - Handles induced lightning-surge coupling on cable-connected interfaces without degradation. |
| Package | DFN2510A-10 (SOT1176-2), 1.0 × 2.5 × 0.5 mm - Enables placement within <2 mm of HDMI/USB connectors for optimal PCB layout and return-path control. |
Pinout & Package
PHDMI2BB4Z uses the leadless DFN2510A-10 (SOT1176-2) package: 1.0 mm × 2.5 mm × 0.5 mm body, 10-terminal ultra-thin SMD outline with exposed thermal pad (GND-connected). Pin 1 index area located at top-left corner in top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 | ESD protection channel for first bidirectional signal line (e.g., HDMI TMDS+ or USB3.2 TX+) |
| 2 | CH2 | ESD protection channel for second bidirectional signal line (e.g., HDMI TMDS− or USB3.2 TX−) |
| 3 | GND | Main transient return path; connects to PCB ground plane for lowest possible clamping impedance |
| 4 | CH3 | ESD protection channel for third bidirectional signal line (e.g., HDMI Clock+ or USB3.2 RX+) |
| 5 | CH4 | ESD protection channel for fourth bidirectional signal line (e.g., HDMI Clock− or USB3.2 RX−) |
| 6, 7, 9, 10 | n.c. | No internal connection; must remain unconnected on PCB to avoid parasitic coupling or solder bridging |
| 8 | GND | Secondary ground terminal; improves thermal dissipation and reduces ground loop inductance when tied to same plane as Pin 3 |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional snap-back clamping | Enables symmetric protection of AC-coupled differential pairs without DC biasing or polarity concerns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4202MR6T1G | Higher capacitance (0.5 pF typ), lower ESD rating (±12 kV), dual-channel only (requires two devices for four lines) | Limited to ≤5 Gbps interfaces; not suitable for HDMI 2.1 or USB 3.2 Gen 2x2 | Select only if cost sensitivity outweighs signal integrity requirements and layout space allows dual-device placement. |
| Texas Instruments TPD4E05U06DQAR | 0.5 pF typ capacitance, ±12 kV ESD, four-channel, but higher VCL (7.5 V @ 6.5 A) | Clamping voltage exceeds safe margin for 3.3 V PHYs under worst-case surge; requires additional series impedance | Acceptable for legacy USB 3.0 or DisplayPort 1.4, but not recommended for HDMI 2.1 or USB 3.2 Gen 2x2 due to signal integrity risk. |
Compared with NUP4202MR6T1G and TPD4E05U06DQAR, PHDMI2BB4Z delivers superior high-speed interface compatibility via its 0.17 pF capacitance and 5.4 V clamping-enabling direct integration on next-gen 10–20 Gbps links without signal conditioning or layout compromise.

FAQ
Can PHDMI2BB4Z be used on single-ended 3.3 V GPIO lines?
Yes-PHDMI2BB4Z supports bidirectional protection on any 3.3 V signal line with ≤±15 kV ESD exposure risk. Its ±3.3 V VRWM ensures zero leakage during normal operation, and its snap-back behavior clamps transients regardless of polarity. However, ensure the protected line does not source unlimited DC current, as sustained conduction may cause thermal stress.
What is the maximum recommended PCB trace length between PHDMI2BB4Z and the HDMI connector?
Trace length should be ≤2 mm from device pins to connector pads. Longer traces increase inductance, raising clamping voltage during fast ESD events and degrading protection effectiveness. Ground vias must be placed within 0.5 mm of each GND pin to minimize return-path inductance and maintain sub-6 V clamping performance.
Does PHDMI2BB4Z require external biasing or series resistors?
No-PHDMI2BB4Z operates passively with no external components required. It is designed for direct placement between signal line and ground. Series resistors are discouraged as they increase clamping voltage and degrade high-frequency response; layout optimization (short traces, solid ground plane) replaces passive filtering.
How does PHDMI2BB4Z perform under repeated ESD strikes?
PHDMI2BB4Z maintains full ±15 kV IEC 61000-4-2 performance after ≥1000 contact discharges per pin, verified per Nexperia's qualification testing. No parameter shift or leakage increase occurs when operated within specified ambient temperature (−40 °C to +125 °C) and transient repetition rates typical of real-world usage.
