Product details
Overview
AOZ8222DI-05 from Alpha and Omega Semiconductor is a two-line unidirectional TVS diode array in a 3-lead DFN 1.0 × 0.6 mm package, rated for 5 V working voltage, ±20 kV IEC 61000-4-2 ESD protection (contact/air), and 5.5 A peak pulse current. It protects high-speed data lines in portable electronics against transients and electrostatic discharge.
For engineers reviewing the AOZ8222DI-05 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 1–12 A, input capacitance (8–18 pF), reverse leakage (<1 µA), low forward voltage (0.6–0.9 V), and thermal rating over –40 °C to +85 °C ambient.
Technical Context
The AOZ8222DI-05 integrates two independent unidirectional TVS diodes between each I/O line and ground (VN), with no internal connection between I/O1 and I/O2. Its architecture enables simultaneous protection of two signal paths without crosstalk coupling.
It operates with a 5.0 V reverse working voltage (VRWM), 6.0 V minimum breakdown voltage (VBR), and clamps transients to ≤9.0 V (positive) / ≥–5.0 V (negative) at 5 A, supporting high-speed interfaces where low capacitance (≤18 pF) and minimal insertion loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous DC operating voltage before conduction begins; matches standard 5 V logic rails. |
| VBR (min) | 6.0 V at 1 mA - Ensures reliable turn-on above normal signal swing while avoiding false triggering. |
| VCL @ 5 A | 9.0 V (pos) / –5.0 V (neg) - Limits transient voltage seen by downstream ICs during 8/20 µs surges. |
| CJ (I/O–GND) | 15–18 pF at 0 V - Low enough to avoid signal integrity degradation on USB 2.0 or audio lines. |
| ESD Rating | ±20 kV contact/air per IEC 61000-4-2 - Exceeds Level 4 immunity requirement for handheld device certification. |
| Package | DFN 1.0 × 0.6 × 0.5 mm, 3-lead - Enables placement near connectors or buttons in space-constrained PCB layouts. |
| Operating Temp | –40 °C to +85 °C ambient - Validated for consumer and industrial portable equipment environments. |
Pinout & Package
AOZ8222DI-05 uses a RoHS-compliant 3-lead DFN package (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; Pin 3 is common cathode (VN), tied internally to ground reference for both diodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | I/O1 Anode | Input/output line 1 anode terminal; connects to protected signal trace (e.g., USB D+). |
| Pin 2 | I/O2 Anode | Input/output line 2 anode terminal; connects to second protected signal trace (e.g., USB D–). |
| Pin 3 | VN (Cathode) | Common cathode node tied to system ground; provides return path for clamped transient current from both I/O lines. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD robustness | ±20 kV contact/air - Eliminates need for external ESD test margining in final product validation. |
| Low channel capacitance | 8–18 pF - Preserves signal rise/fall times on 480 Mbps USB 2.0 or 24 MHz SPI lines. |
| Unidirectional dual-channel topology | Independent I/O1–VN and I/O2–VN paths - Prevents coupling between protected lines during surge events. |
| Low clamping voltage at 5 A | 9.0 V / –5.0 V - Keeps protected ICs within absolute maximum ratings during 5.5 A peak transients. |
| Small footprint | 0.6 mm² area - Fits within 1.5 mm clearance from edge-mount USB connectors in ultra-thin devices. |
Applications
| USB 2.0 Data Lines | Keypad/Button ESD Protection |
|---|---|
Use Scenario: Protecting D+ and D– lines of a USB 2.0 interface in a portable GPS unit exposed to repeated user-handling ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS array clamping fast-rising transients before they reach the USB transceiver IC. Use Value: Maintains 480 Mbps data integrity while surviving ±20 kV contact discharges per IEC 61000-4-2 without signal distortion. | Use Scenario: Shielding mechanical keypad matrix lines in a ruggedized MP3 player from finger-tip ESD during frequent button presses. IC Role / Device Role / Timing Role: Dual-channel transient suppressor placed directly at keypad connector to shunt ESD energy to ground. Use Value: Prevents microcontroller reset or phantom keypresses caused by >8 kV contact discharges, validated to HBM ±30 kV. |
| Notebook Computer Audio Jack | Digital Camera Control Interface |

IC Role / Device Role / Timing Role: Two-line TVS limiting voltage excursions on left/right channel and mic bias lines to <9 V during 100 ns pulses. Use Value: Avoids op-amp saturation or ADC clipping during transient events, enabled by 15–18 pF capacitance and low insertion loss below 100 MHz. | Use Scenario: Protecting serial control lines (e.g., I²C SDA/SCL) between image sensor and baseband processor in a compact digital camera module. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional array (ground-referenced) suppressing ESD on low-voltage control signals. Use Value: Ensures reliable startup and configuration of CMOS image sensors under ±15 kV air discharge, with <1 µA leakage preserving battery life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A | Single-line, SMA package (4.5 × 2.7 mm), 5.0 V VRWM, 100 W peak power, higher capacitance (>100 pF) | Not suitable for high-speed data lines; intended for power rail or low-frequency signal protection | Select only when board space allows larger footprint and signal bandwidth <1 MHz |
| TPD2E001DRYR | Two-line, DRY (1.0 × 0.6 mm) package, 5.0 V VRWM, ±8 kV IEC 61000-4-2, 12 pF typical capacitance | Limited to ±8 kV ESD level - insufficient for full Level 4 compliance in harsh handling environments | Acceptable for cost-sensitive designs where ±15 kV air discharge is not required |
Compared with SMA6J5.0A and TPD2E001DRYR, the AOZ8222DI-05 uniquely delivers ±20 kV ESD robustness in a 1.0 × 0.6 mm footprint with sub-18 pF capacitance-enabling USB 2.0 and audio interface protection where space, speed, and certification rigor are jointly constrained.

FAQ
What is the maximum clamping voltage of the AOZ8222DI-05 at 5 A peak pulse current?
The AOZ8222DI-05 clamps positive transients to 9.0 V and negative transients to –5.0 V at 5 A peak pulse current (tp = 100 ns). This value is measured per I/O pin to ground and ensures protected downstream ICs remain within safe operating voltage limits during surge events.
Does the AOZ8222DI-05 support bidirectional signal protection?
No, the AOZ8222DI-05 is a unidirectional TVS diode array. Each channel (I/O1–VN and I/O2–VN) conducts only during negative voltage excursions relative to VN (ground), making it suitable for DC-biased or single-polarity signal lines like USB 2.0 or keypad scan lines.
What is the input capacitance of AOZ8222DI-05 between I/O pins and ground?
The AOZ8222DI-05 exhibits 15–18 pF input capacitance between any I/O pin and ground at 0 V reverse bias and 1 MHz frequency. This low value minimizes loading on high-speed data lines while maintaining effective ESD suppression.
Can AOZ8222DI-05 be used in automotive infotainment systems?
The AOZ8222DI-05 is qualified for –40 °C to +85 °C ambient operation and meets IEC 61000-4-2 Level 4, but it is not AEC-Q200 qualified. For automotive infotainment, use requires additional system-level validation; AOS does not authorize its use in safety-critical or life-support functions.
Is the DFN package of AOZ8222DI-05 lead-free and RoHS compliant?
Yes, the AOZ8222DI-05 uses a RoHS-compliant 3-lead DFN 1.0 × 0.6 mm package and is part of AOS Green Products, with reduced halogen content. Full compliance documentation is available via AOS's Green Policy at aosmd.com/media/AOSGreenPolicy.pdf.
