Product details
Overview
AoZ8002DI from Alpha & Omega Semiconductor is a dual-channel, low-capacitance ESD protection diode array designed for high-speed data lines including USB 2.0, HDMI, and DisplayPort interfaces. It features 0.55pF typical channel capacitance, ±15kV HBM ESD rating, and a 5.5V working voltage, enabling robust transient suppression without signal integrity degradation in portable electronics.
For engineers reviewing the AOZ8002DI datasheet, pinout, applications, or equivalent options, key selection criteria include channel-to-channel capacitance matching, IEC 61000-4-2 Level 4 compliance, low clamping voltage under 12V at 1A, and DFN-10 (2.5 × 1.0 mm) package compatibility with high-density PCB layouts.
Technical Context
The AOZ8002DI integrates two independent bidirectional ESD protection channels in a single DFN-10 package. Each channel uses silicon avalanche diode structures optimized for sub-1V dynamic resistance and fast response time (<1ns) to transient events.
It operates within -40°C to +125°C ambient temperature range and supports peak pulse current up to 4A per channel per IEC 61000-4-2 (8/20μs waveform), with leakage current below 100nA at rated reverse voltage.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB30DRYR | 0.7pF channel capacitance; ±12kV HBM; 3.6V VRWM | Better suited for 3.3V-only systems; higher capacitance limits USB 2.0 eye margin | Select when lower working voltage and TI ecosystem support are prioritized over minimal capacitance |
| SZ1.8SMCG-TP | Single-channel; 0.35pF; ±30kV HBM; SOD-323 package | Requires two devices for dual-channel use; smaller footprint but no integrated ground pad | Choose for space-constrained designs where discrete placement and ultra-low capacitance outweigh integration benefits |
Compared with AOZ8002DI, TPD2EUSB30DRYR offers tighter voltage tolerance but sacrifices signal fidelity at 480Mbps, while SZ1.8SMCG-TP delivers lower capacitance in a smaller package but increases assembly cost and layout complexity due to dual-device implementation.

FAQ
What is the maximum peak pulse current rating for AOZ8002DI per channel?
AoZ8002DI is rated for 4A peak pulse current per channel under IEC 61000-4-2 (8/20μs waveform) conditions. This value is verified per standard test setup with 2Ω source impedance and confirms robustness against real-world ESD events without degradation. The AOZ8002DI maintains clamping voltage below 12V at this current level, protecting downstream PHY circuitry effectively.
Does AOZ8002DI require external biasing or control signals to operate?
No, AOZ8002DI is a passive, bidirectional ESD protection device that requires no external power, biasing, or control signals. It functions solely through avalanche breakdown of integrated silicon diodes during transient overvoltage events. The AOZ8002DI activates automatically when line voltage exceeds its breakdown threshold, making it fully transparent during normal operation.
Is AOZ8002DI compatible with lead-free reflow soldering processes?
Yes, AOZ8002DI is qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020, with a maximum peak temperature of 260°C. Its halogen-free DFN-10 package meets RoHS Directive 2011/65/EU and supports standard Pb-free assembly lines without modification. The AOZ8002DI's thermal pad design ensures reliable solder joint formation and mechanical stability.
Can AOZ8002DI be used on differential pairs such as USB D+ and D− simultaneously?
Yes, AOZ8002DI contains two independent, bidirectional channels-each capable of protecting one differential pair like USB D+ and D−. Its matched channel capacitance (0.55pF typ) and symmetrical clamping ensure common-mode noise rejection and signal skew minimization. The AOZ8002DI's pinout allows direct placement across both lines without cross-talk or imbalance.
What is the operating temperature range for AOZ8002DI?
AoZ8002DI is specified for continuous operation from −40°C to +125°C ambient temperature. This range covers extended industrial and automotive cabin environments. Thermal performance is validated with the exposed pad soldered to PCB copper, and derating is not required within this envelope. The AOZ8002DI retains full ESD protection capability across the entire range.
