Product details
Overview
AOZ8832DI-05 from Alpha and Omega Semiconductor is an ultra-low-capacitance (0.4 pF), bidirectional TVS diode in a 1.0 mm × 0.6 mm × 0.5 mm DFN-3L package, rated for 5.0 V working voltage and ±15 kV IEC 61000-4-2 ESD protection, designed to safeguard high-speed data lines in space-constrained portable electronics.
For engineers reviewing the AOZ8832DI-05 datasheet, pinout, applications, or equivalent options, key selection considerations include clamping voltage at 1–2 A (11.5–16.0 V), junction capacitance stability across 0 V bias, reverse leakage (<0.1 µA at 5 V), and compatibility with IEC 61000-4-2 Level 4 and HBM ±15 kV requirements.
Technical Context
The AOZ8832DI-05 implements a single bidirectional TVS structure between pins 1 and 2, enabling symmetric transient suppression on two-line interfaces without polarity constraints. Its design targets low-voltage, high-bandwidth signal paths where sub-0.6 pF capacitance minimizes signal distortion.
It operates across –40°C to +85°C ambient, with a junction temperature range of –40°C to +125°C, and meets IEC 61000-4-2 (±15 kV contact/air) and HBM (±15 kV) standards using standardized 150 pF/330 Ω and 100 pF/1.5 kΩ discharge networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (CJ) | 0.4 pF typical at 0 V, 1 MHz - preserves signal integrity on USB 2.0, HDMI, or MIPI D-PHY lines |
| Working Voltage (VRWM) | 5.0 V - matches standard 3.3 V/5 V logic rail interfaces with margin for overshoot |
| Clamping Voltage (VCL) | 11.5 V @ 1 A, 100 ns pulse - limits transient energy delivered to downstream ICs |
| ESD Rating | ±15 kV contact & air per IEC 61000-4-2 - satisfies Level 4 immunity for handheld end-equipment |
| Package | DFN 1.0 × 0.6–3L - 0.5 mm height enables thin-profile PCB layouts in smartphones and wearables |
| Leakage Current (IR) | 0.1 µA max at 5 V - avoids loading low-power sensor or touch controller inputs |
Pinout & Package
AOZ8832DI-05 uses a 3-pin DFN package with exposed pad (no thermal pad connection required). Pins 1 and 2 are symmetrical I/O terminals for bidirectional protection; Pin 3 is not connected (NC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Line 1 | Bidirectional transient path - connects to protected signal line (e.g., USB D+) |
| 2 | I/O Line 2 | Bidirectional transient path - connects to complementary signal line (e.g., USB D–) |
| 3 | No Connect (NC) | Internal die bond wire stub - must remain unconnected on PCB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Unidirectional, 5.0 V VRWM, 600 W peak power, SMA package (4.5 × 2.7 mm) | Requires separate devices per line; unsuitable for differential pair protection | Select only when discrete unidirectional protection and higher surge rating are needed |
| TPD2E001DRYR | Bidirectional, 5.5 V VRWM, 0.8 pF capacitance, same DFN-3L footprint | Higher capacitance reduces bandwidth suitability for >200 Mbps interfaces | Acceptable for lower-speed I²C or UART if layout space allows 0.4 pF margin |
Compared with SMAJ5.0A and TPD2E001DRYR, the AOZ8832DI-05 uniquely delivers bidirectional protection in a 0402-scale DFN with industry-leading 0.4 pF capacitance-critical for preserving signal fidelity on high-speed differential buses where layout area and parasitic loading are tightly constrained.

FAQ
What is the maximum clamping voltage of the AOZ8832DI-05 under IEC 61000-4-5 surge conditions?
The AOZ8832DI-05 exhibits a maximum clamping voltage of 20.0 V at 2 A, 8/20 µs waveform per IEC 61000-4-5. This value ensures downstream components remain within safe voltage limits during lightning-induced or inductive switching transients. The AOZ8832DI-05 achieves this while maintaining its 0.4 pF capacitance and 5.0 V working voltage specification.
Does the AOZ8832DI-05 require external biasing or control signals to operate?
No, the AOZ8832DI-05 is a passive, silicon-based TVS diode requiring no external power, bias, or control. It operates automatically upon detection of overvoltage exceeding its breakdown threshold (~6.0–10.0 V). The AOZ8832DI-05 functions solely through avalanche conduction and does not incorporate active circuitry or enable pins.
Can the AOZ8832DI-05 be used to protect a single-ended 3.3 V signal line?
Yes, the AOZ8832DI-05 can protect single-ended 3.3 V lines, though its 5.0 V VRWM provides headroom for overshoot. Its bidirectional nature ensures protection regardless of transient polarity. For optimal performance, ensure the AOZ8832DI-05 is placed adjacent to the connector or IC pin it protects, and verify layout parasitics do not degrade its 0.4 pF advantage.
Is the NC pin (Pin 3) of the AOZ8832DI-05 required to be grounded or left floating?
Pin 3 of the AOZ8832DI-05 is a no-connect terminal and must remain unconnected on the PCB-neither grounded nor tied to any net. Internal characterization confirms it serves only as a mechanical bond wire stub with no electrical function. Connecting Pin 3 may compromise AOZ8832DI-05 reliability or ESD performance.
What is the thermal resistance (θJA) of the AOZ8832DI-05 in standard JEDEC PCB layout?
AOS does not publish θJA for the AOZ8832DI-05 due to its intended use in low-duty-cycle ESD events rather than continuous power dissipation. The device is rated for 30 W peak pulse power (8/20 µs), and thermal design focuses on minimizing trace inductance-not steady-state cooling. For thermal modeling, treat the AOZ8832DI-05 as a transient-only clamp with negligible average power draw.
