Product details
Overview
AOZ8S507BDS-07 from Alpha & Omega Semiconductor is a 1-channel bidirectional high-surge TVS diode designed for ESD and surge protection on data and power lines. It delivers ±30 kV IEC 61000-4-2 ESD immunity (air/contact), 9 A IEC 61000-4-5 (8/20 µs) surge rating, 19 pF junction capacitance, 7 V reverse working voltage, and operates from −40°C to +125°C - ideal for audio line and mobile device interface protection.
For engineers reviewing the AOZ8S507BDS-07 datasheet, pinout, applications, or equivalent options, key selection factors include clamping voltage under 11 V at 30 A TLP, low 19 pF capacitance for high-speed signal integrity, bidirectional snapback behavior, RoHS/Halogen-Free DFN1.0×0.6-2L package, and compliance with IEC 61000-4-2/4-4/4-5 standards.
Technical Context
The AOZ8S507BDS-07 integrates two unidirectional TVS diodes in antiparallel configuration within a single DFN package to enable bidirectional transient conduction. Its snapback behavior provides hold voltage of 7 V at 100 mA, ensuring stable clamping during sustained overvoltage events.
It supports dual-standard transient suppression: ±30 kV ESD per IEC 61000-4-2 (150 pF/330 Ω), and 9 A peak surge per IEC 61000-4-5 (8/20 µs waveform), with verified clamping voltage ≤10.5 V at 9 A IPP and ≤11 V at 30 A TLP - critical for protecting sensitive analog and digital I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage (VRWM) | 7 V - maximum continuous DC or RMS voltage the device blocks without leakage exceeding 100 nA. |
| Breakdown Voltage (VBR) | 7.8–11 V at IT = 1 mA - defines onset of avalanche conduction; ensures reliable triggering before system damage. |
| Clamping Voltage (VCL) | ≤11 V at 30 A TLP - limits peak voltage seen by protected circuitry during fast transients. |
| Junction Capacitance (CJ) | 19 pF at 0 V, 1 MHz - low enough to avoid signal distortion on audio and USB 2.0 lines. |
| Surge Rating | 9 A (8/20 µs) per IEC 61000-4-5 - withstands lightning-induced surges on power rails and interfaces. |
| ESD Rating | ±30 kV air/contact per IEC 61000-4-2 - exceeds industrial and consumer ESD immunity requirements. |
| Operating Temperature | −40°C to +125°C TJ - supports deployment in automotive cabin modules and industrial edge controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Unidirectional, SMA package (4.5 mm × 2.7 mm), 100 pF capacitance, 10.5 V clamping at 10 A. | Requires external series resistor for bidirectional protection; unsuitable for high-speed data lines due to high capacitance. | Select only for low-frequency power rail protection where size and speed are secondary. |
| SP1003-07UTG | Bidirectional, SOD-323 package (1.7 mm × 1.25 mm), 12 pF capacitance, 12 V clamping at 30 A, −40°C to +125°C. | Lower capacitance but higher clamping voltage; rated for 15 kV ESD (not 30 kV), limiting use in premium consumer handsets. | Prefer when ultra-low capacitance is prioritized over maximum ESD robustness in space-constrained designs. |
Compared with SMAJ7.0A and SP1003-07UTG, the AOZ8S507BDS-07 uniquely balances 19 pF capacitance, ±30 kV ESD rating, and compact DFN1.0×0.6-2L footprint - making it optimal for high-density mobile audio and USB 2.0 protection where both signal fidelity and ruggedness are required.

FAQ
What is the clamping voltage of AOZ8S507BDS-07 at 9 A surge current?
The AOZ8S507BDS-07 has a clamping voltage of ≤10.5 V at 9 A peak pulse current (IEC 61000-4-5, 8/20 µs waveform). This value is measured under standardized surge conditions and guarantees that protected downstream components experience no more than 10.5 V during such events. The AOZ8S507BDS-07 maintains this performance across its full operating temperature range of −40°C to +125°C.
Is AOZ8S507BDS-07 suitable for USB 2.0 D+ and D− line protection?
Yes, AOZ8S507BDS-07 is suitable for USB 2.0 D+ and D− line protection due to its 19 pF junction capacitance, which introduces negligible signal degradation at 480 Mbps full-speed operation. Its bidirectional structure eliminates polarity concerns, and ±30 kV ESD rating exceeds USB-IF compliance requirements. The AOZ8S507BDS-07 must be placed within 3 mm of the USB connector for optimal high-frequency transient suppression.
What is the reverse leakage current specification for AOZ8S507BDS-07 at its rated VRWM?
The AOZ8S507BDS-07 exhibits reverse leakage current of ≤100 nA when biased at its maximum reverse working voltage of 7 V (VRWM), measured at TA = 25°C. This low leakage ensures minimal power loss and no measurable impact on rail stability in battery-powered systems. The AOZ8S507BDS-07 maintains leakage below 1 µA even at +125°C junction temperature per characterization data.
Does AOZ8S507BDS-07 meet automotive AEC-Q200 stress testing requirements?
No, AOZ8S507BDS-07 is not AEC-Q200 qualified. It is rated for −40°C to +125°C junction temperature and meets IEC 61000-4-2/4-4/4-5 standards, but lacks formal AEC-Q200 qualification documentation. For automotive infotainment applications, AOZ8S507BDS-07 may be used in non-safety-critical subsystems subject to customer-specific validation. The AOZ8S507BDS-07 does not carry AEC-Q200 certification per Alpha & Omega's published product status.
What package type and dimensions does AOZ8S507BDS-07 use?
AOZ8S507BDS-07 uses the DFN1.0×0.6-2L package: 1.0 mm length × 0.6 mm width × 0.5 mm height, with two terminals and no exposed pad. It is RoHS-compliant and Halogen-Free per AOS Green Product policy. The AOZ8S507BDS-07's compact footprint enables placement in tight spaces near connectors and high-density BGA layouts typical in smartphones and ultrabooks.
