Product details
Overview
AOZ8005CIL from Alpha & Omega Semiconductor is an ultra-low capacitance TVS diode array designed to protect four high-speed differential data lines (e.g., HDMI TX/RX pairs) against ESD transients. It features 0.47 pF line-to-line capacitance, ±15 kV IEC 61000-4-2 contact/air ESD immunity, and a 5.0 V operating voltage - enabling signal integrity preservation up to 2 GHz in HDMI 1.3-compliant digital video interfaces.
For engineers reviewing the AOZ8005CIL datasheet, pinout, applications, or equivalent options, key selection criteria include low clamping voltage (10.5 V @ 1 A), flow-through SOT-23-6 layout for minimal trace discontinuity, precise 100 Ω differential impedance compatibility, and RoHS-compliant green packaging for consumer electronics and embedded display systems.
Technical Context
The AOZ8005CIL integrates eight surge-rated steering diodes and one internal TVS in a single SOT-23-6 package. During ESD events, steering diodes forward-bias to shunt transient current either to VP (5.0 V supply rail) or VN (ground), clamping I/O pins with ≤16.0 V at 12 A peak pulse current.
Its flow-through pinout (CH1–CH4 on pins 1/2/4/5; VP/VN on pins 6/3) enables direct in-line placement on HDMI differential pairs without trace routing detours. The device operates across –40°C to +85°C ambient temperature and maintains <0.03 pF capacitance matching between channels for balanced signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Line-to-Line Capacitance | 0.47 pF - preserves HDMI 1.3 signal integrity up to 2 GHz with minimal insertion loss. |
| ESD Rating (IEC 61000-4-2) | ±15 kV air / ±8 kV contact - meets Level 4 immunity for consumer port protection. |
| Clamping Voltage (IPP = 1 A) | 10.5 V (positive) / –2.0 V (negative) - limits transient overvoltage to safe levels for downstream HDMI receivers. |
| Reverse Working Voltage (VRWM) | 5.5 V - exceeds standard 5.0 V HDMI supply, ensuring no leakage during normal operation. |
| Operating Temperature Range | –40°C to +85°C ambient - supports deployment in set-top boxes, monitors, and notebook computers. |
| Package | SOT-23-6 - compact footprint (2.9 × 2.8 × 1.1 mm) saves PCB space in dense I/O layouts. |
| RoHS Compliance | Green product with reduced halogen content - satisfies global environmental compliance requirements. |
Pinout & Package
SOT-23-6 package with flow-through layout optimized for HDMI differential pair routing: pins 1–2–4–5 carry protected I/O channels (CH1–CH4), pin 3 is VN (ground reference), and pin 6 is VP (5.0 V supply rail). Pins 3 and 6 provide low-inductance clamping paths; no-connect pins are absent - all six terminals are functional.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CH1 (I/O Channel 1) | Protected differential signal line (e.g., HDMI TX0+); connects internally to steering diode anode/cathode pair. |
| 2 | CH2 (I/O Channel 2) | Protected differential signal line (e.g., HDMI TX0−); enables matched pair routing with CH1. |
| 3 | VN (Ground Reference) | Low-impedance return path for negative transients; must connect directly to solid ground plane. |
| 4 | CH3 (I/O Channel 3) | Protected differential signal line (e.g., HDMI TX1+); maintains <0.03 pF capacitance matching with CH1–CH4. |
| 5 | CH4 (I/O Channel 4) | Protected differential signal line (e.g., HDMI TX1−); completes four-channel protection set. |
| 6 | VP (Supply Rail) | 5.0 V clamping rail for positive transients; ties to clean, low-noise HDMI supply with minimal trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low line-to-line capacitance | 0.47 pF ensures <–3 dB insertion loss up to 2340 MHz - critical for HDMI 1.3 1080p60 signal fidelity. |
| Flow-through SOT-23-6 pinout | Enables straight-through PCB trace routing across CH1–CH2–CH3–CH4, eliminating stubs and impedance discontinuities. |
| Four-channel ESD protection | Simultaneously safeguards two full HDMI differential pairs (TX0+/−, TX1+/−) with matched clamping behavior. |
| Low clamping voltage | 10.5 V @ 1 A peak pulse prevents damage to sensitive HDMI receiver inputs rated ≤12 V absolute maximum. |
| HDMI-optimized thermal & electrical design | Rated for –40°C to +85°C ambient and qualified per JESD22-A108B HTOL (500 hrs @ 125°C) for long-term reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | 0.5 pF line-to-line capacitance; ±12 kV contact ESD rating; SOT-23-6 package. | Lower ESD robustness; suitable for cost-sensitive HDMI 1.2 designs but not HDMI 1.3 2.25 Gbps compliance. | Select SP1006-04UTG only if ±12 kV ESD immunity suffices and 0.03 pF capacitance matching is non-critical. |
| TPD4E001DPYR | 0.5 pF line-to-line capacitance; ±15 kV air/±8 kV contact; 4-channel; X2SON-8 package (1.35 × 1.15 mm). | Smaller footprint but asymmetric pinout requires trace bends; lacks dedicated VP/VN rails - clamps to VCC/GND only. | Choose TPD4E001DPYR when board space is constrained and HDMI impedance control is less stringent than AOZ8005CIL's flow-through advantage. |
Compared with SP1006-04UTG and TPD4E001DPYR, the AOZ8005CIL delivers superior HDMI 1.3 compliance via its 0.47 pF capacitance, matched channel performance, and VP/VN-referenced clamping architecture - making it optimal for high-fidelity video interfaces where signal integrity and ESD margin are co-constrained.

FAQ
What is the primary function of the AOZ8005CIL in an HDMI interface?
The AOZ8005CIL serves as a four-channel transient voltage suppressor array that protects HDMI differential signal pairs (e.g., TX0+/−, TX1+/−) from ESD events. It clamps transient voltages to safe levels using internal steering diodes and a TVS, with 0.47 pF line-to-line capacitance to preserve signal integrity up to 2 GHz - ensuring compliance with HDMI 1.3 specifications in devices like digital TVs and set-top boxes. The AOZ8005CIL achieves this while maintaining matched channel performance and flow-through routing capability.
Does the AOZ8005CIL require external biasing or control signals?
No, the AOZ8005CIL operates passively and requires no external biasing, control logic, or enable signals. It functions solely through its internal diode structure: during normal operation, it presents negligible leakage (<1 µA at 5 V), and during ESD events, steering diodes automatically forward-bias to divert transient current to VP (5.0 V rail) or VN (ground). This autonomous behavior makes the AOZ8005CIL ideal for plug-and-play HDMI protection without firmware or circuit modifications.
How does the AOZ8005CIL's SOT-23-6 pinout improve HDMI PCB layout?
The AOZ8005CIL's SOT-23-6 flow-through pinout (CH1–CH2–VN–CH3–CH4–VP) allows HDMI differential pairs to route straight through the device with no trace bends or vias - minimizing impedance discontinuities and crosstalk. This layout reduces parasitic inductance, maintains 100 Ω ±15% differential impedance, and avoids the >20 Ω impedance drop common with non-optimized TVS placements. The AOZ8005CIL thus simplifies high-speed HDMI board design while improving ESD immunity margin.
Can the AOZ8005CIL be used for USB 2.0 data line protection?
Yes, the AOZ8005CIL is explicitly listed in its datasheet for USB 2.0 power and data line protection. Its 0.47 pF line-to-line capacitance avoids signal degradation at 480 Mbps, ±15 kV IEC 61000-4-2 ESD rating exceeds USB specification requirements, and 5.0 V operating voltage aligns with standard USB VBUS levels. However, designers must verify that the VP/VN connections match the target USB host/device power architecture, as the AOZ8005CIL clamps to both rails rather than ground-only.
What is the maximum peak pulse current the AOZ8005CIL can handle?
The AOZ8005CIL is rated for 12 A peak pulse current (IPP) under 100 ns TLP conditions, with corresponding clamping voltages of 16.0 V (positive) and –5.5 V (negative). This rating is validated per IEC 61000-4-2 surge testing methodology and ensures reliable protection against severe ESD events in consumer electronics environments. The AOZ8005CIL maintains these performance characteristics across its full –40°C to +85°C operating temperature range without derating.
