Product details
Overview
AOZ8822DI-05 from Alpha and Omega Semiconductor is an ultra-low capacitance two-line TVS diode in a 3-lead DFN 1.0 × 0.6 mm package, rated for ±15 kV IEC 61000-4-2 ESD protection, 5 V working voltage, and 0.55 pF junction capacitance, designed to protect high-speed data lines such as USB 2.0, HDMI, and keypad interfaces against transients and electrostatic discharge.
For engineers reviewing the AOZ8822DI-05 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 1–2 A (13–14 V), reverse leakage ≤0.1 µA at 5 V, junction temperature range (−40 °C to +125 °C), and compatibility with space-constrained portable electronics requiring RoHS-compliant, green packaging.
Technical Context
The AOZ8822DI-05 integrates two unidirectional TVS diodes in a single DFN-3L package, each configured between an I/O line and ground. It operates with a 5 V reverse working voltage (VRWM) and achieves breakdown at 6.0–10.0 V (VBR @ 1 mA), enabling robust overvoltage clamping without interfering with normal signal integrity.
Its ultra-low 0.55 pF typical capacitance minimizes signal distortion on high-frequency lines up to 10 GHz, while its 14 V clamping voltage at 2 A (8/20 µs pulse) ensures effective transient energy diversion to ground under IEC 61000-4-5 surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±15 kV contact & air discharge - meets Level 4 immunity for handheld and portable end-equipment |
| Junction Capacitance (CJ) | 0.55 pF @ 0 V, 1 MHz - preserves signal integrity on USB 2.0, HDMI, and MIPI lines |
| Clamping Voltage (VCL) | 13 V @ 1 A, 14 V @ 2 A (100 ns pulse) - limits transient overvoltage to safe levels for 5 V logic |
| Working Peak Reverse Voltage (VRWM) | 5.0 V - matches standard 5 V I/O rail voltage without leakage or false triggering |
| Reverse Leakage Current (IR) | ≤0.1 µA @ VRWM = 5 V - prevents standby power loss in battery-powered devices |
| Package Dimensions | DFN 1.0 × 0.6 × 0.5 mm - enables placement adjacent to connectors and high-density BGA ICs |
Pinout & Package
AOZ8822DI-05 uses a 3-lead DFN (Dual Flat No-lead) package measuring 1.0 mm × 0.6 mm × 0.5 mm, with exposed thermal pad not electrically connected. Pin 1 and Pin 2 are I/O terminals for separate high-speed lines; Pin 3 is common ground connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O Line 1 Anode | Connects to first protected signal line (e.g., USB D+); cathode internally tied to ground |
| Pin 2 | I/O Line 2 Anode | Connects to second protected signal line (e.g., USB D−); cathode internally tied to ground |
| Pin 3 | Ground (Cathode Common) | Common low-inductance return path for both TVS channels; must be routed to solid ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional dual-channel protection | Two independent 5 V-rated TVS paths in one footprint - eliminates need for discrete dual-diode arrays |
| Ultra-low 0.55 pF capacitance | Enables use on >480 Mbps USB 2.0 and 1.65 Gbps HDMI 1.4a without insertion loss degradation |
| ±15 kV IEC 61000-4-2 compliance | Validated ESD immunity for consumer-grade portable electronics without external shielding |
| RoHS-compliant green packaging | Halogen-free, lead-free DFN construction - satisfies EU WEEE and China RoHS environmental mandates |

IC Role / Device Role / Timing Role: Two-line TVS placed per key row/column pair, providing localized clamping without adding series resistance. Use Value: 5 V VRWM aligns with microcontroller GPIO voltage; 0.1 µA leakage avoids false key detection during sleep mode. | Use Scenario: Protecting volume-up/down, play/pause, and headphone detect lines in battery-powered MP3 players. IC Role / Device Role / Timing Role: Low-capacitance TVS on control lines routed near PCB edge, minimizing trace inductance to ground. Use Value: Compact 1.0 × 0.6 mm footprint saves board area; −40 °C to +85 °C operating range supports outdoor usage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5 × 2.7 mm), 600 W peak power, 100 pF capacitance | Designed for board-level surge (IEC 61000-4-5), not high-speed data lines | Select only for cost-sensitive, low-frequency I/O where capacitance <1 pF is not required |
| TPD2E001DRYR | 2-channel, 0.9 pF typical capacitance, ±8 kV IEC 61000-4-2, same DFN-3L (1.0 × 0.6 mm) footprint | Limited to lower ESD level; lower clamping voltage (9.5 V @ 1 A) but reduced robustness | Choose when system-level testing confirms ±8 kV sufficient and lower clamping is prioritized over margin |
Compared with SMAJ5.0A and TPD2E001DRYR, the AOZ8822DI-05 uniquely balances ultra-low capacitance (0.55 pF), full ±15 kV ESD rating, and miniature DFN-3L size-making it optimal for next-generation portable interfaces where signal fidelity and board space are co-constrained.

FAQ
What is the maximum clamping voltage of the AOZ8822DI-05 under IEC 61000-4-5 surge conditions?
The AOZ8822DI-05 exhibits a clamping voltage of 14.5 V at 1 A and 19 V at 2 A under IEC 61000-4-5 (8/20 µs) surge conditions. These values are measured between I/O pin and ground, confirming its ability to limit transient overvoltage to safe levels for 5 V logic circuits while maintaining reliable operation across its −40 °C to +85 °C ambient range.
Does the AOZ8822DI-05 support bidirectional ESD protection?
No, the AOZ8822DI-05 provides unidirectional protection only. Each channel is configured as an anode-to-ground TVS diode, optimized for 5 V DC-biased signal lines. It does not support symmetrical ±5 V signaling or AC-coupled interfaces requiring bidirectional clamping-applications needing that functionality require a different part number such as AOZ8822DI-06.
Can the AOZ8822DI-05 be used on 3.3 V I/O lines?
Yes, the AOZ8822DI-05 can be used on 3.3 V I/O lines, provided design margins accommodate its 5.0 V VRWM and 6.0–10.0 V VBR. Its low leakage (≤0.1 µA at 5 V) prevents interference, but system-level validation is required to ensure clamping behavior remains within safe operating limits for 3.3 V receivers during ESD events.
What is the thermal pad configuration of the AOZ8822DI-05 DFN package?
The AOZ8822DI-05 DFN package includes an exposed thermal pad on the bottom surface, which is not electrically connected to any internal node. It serves solely for mechanical mounting and thermal conduction to the PCB ground plane. Soldering this pad improves thermal performance but does not alter electrical functionality or pin assignments.
Is the AOZ8822DI-05 compliant with automotive AEC-Q200 requirements?
No, the AOZ8822DI-05 is not AEC-Q200 qualified. Its specified ambient temperature range is −40 °C to +85 °C, and it lacks automotive-grade qualification testing per AEC-Q200 Rev H. For automotive infotainment or body electronics, engineers must select an AEC-Q200–qualified alternative or perform full component-level qualification per their OEM's requirements.
