AU02WS

Overview

The AU02WS is a single rectifier diode manufactured by Sanken Electric USA Inc., designed for through-hole mounting. It features an average rectified current of 800 mA and a maximum forward voltage of 1.3 V at the rated current. The component has a reverse recovery time (trr) of 400 ns, indicating its switching speed characteristics. While specific peak repetitive reverse voltage ratings are not detailed in the provided source text, the device is categorized as a general-purpose or fast-recovery diode suitable for power supply applications requiring moderate current handling.

Feature Summary

• Through-hole package construction for standard PCB mounting
• Fast reverse recovery characteristic with 400 ns trr
• Capable of handling 800 mA average rectified current

Applications

• General purpose rectification in power supplies
• Freewheeling diodes in DC-DC converters
• Protection circuits against reverse polarity

Procurement Notes

Verify the exact voltage rating before procurement, as the provided documentation does not explicitly state the Peak Repetitive Reverse Voltage (Vrrm). Confirm that the 800 mA current rating aligns with your thermal management design. Ensure the through-hole package dimensions match your board layout requirements. Cross-reference the manufacturer's latest datasheet to confirm any updates to the electrical specifications or pinout configuration.

Selection Notes

Select this component when a through-hole solution is required for low-to-medium current rectification. The 400 ns reverse recovery time makes it suitable for frequencies higher than standard slow recovery diodes but potentially slower than ultra-fast types. Consider thermal dissipation capabilities if operating near the 800 mA limit. Compare against similar Sanken diodes if space constraints or specific voltage ratings differ from project needs.

Part Context

Sanken Electric USA Inc. produces a range of discrete semiconductors, including diodes and transistors, often utilized in automotive and industrial electronics.
