AOZ8809DI-05

AOZ8809DI-05 is a power-management IC from Alpha & Omega Semiconductor (AOS), part of the AOZ8809 family. It is a DC-DC converter (typically a synchronous buck) used to generate regulated voltages in compact power supplies for portable/embedded electronics. It usually integrates high- and low-side MOSFETs and offers features such as enable control, soft-start, fast transient response, and protections (overcurrent/overtemperature). The “-05” suffix denotes a specific package/reel/option variant rather than a change in topology. For exact electrical specs (input/output voltage range, current capability, switching frequency, quiescent current) and packaging, consult the official datasheet or a distributor page (AOS, Digi-Key, Mouser).

Exact equivalents depend on the device function and package. If AOZ8809DI-05 is an ESD protection diode array, cross-reference by same channel count, breakdown voltage (Vbr), input capacitance (Cj), leakage, and package. Possible alternatives: Nexperia PESD multi-line arrays, STMicroelectronics ESC/ESDAX series, Onsemi ESD arrays, TI TPD series where applicable. For a precise match, please share the datasheet or required specs (Vmax, Cj, channels, package).

Pin count: 8 pins.
Function: AOZ8809DI-05 is a multi-channel ESD protection diode array (5-channel) with a common ground, used to protect high-speed data lines from ESD/transient events.

- Manufacturer: Alpha and Omega Semiconductor (AOS), often branded as AOS (AOZ series).
- What kind of company: A global semiconductor company that designs and manufactures power management devices, including power MOSFETs, PMICs, and related power electronics components.

Typical application areas for AOZ8809DI-05 (a Power Management IC from Alpha & Omega Semiconductor) include:
