• Signal clamping and protection applications
• Small signal switching in consumer electronics

Single Diodes Procurement Notes

Verify the specific ordering suffix against the official onsemi datasheet to ensure compatibility with required packaging or testing standards. Confirm that the component meets RoHS and REACH compliance requirements as specified in the manufacturer's documentation before integration into production designs.

Single Diodes Selection Notes

Select this component when a standard silicon switching diode with 150 V reverse voltage and 500 mA continuous current capacity is required. The DO-35 package suits through-hole mounting constraints. Ensure the application does not exceed the 4 A surge current limit or the 175 °C maximum junction temperature during operation.

Single Diodes Part Context

This part belongs to the family of general-purpose small signal diodes designed for reliable performance in discrete semiconductor applications. It serves as a fundamental component for basic rectification and switching tasks where moderate voltage blocking and low leakage are prioritized over high-speed recovery characteristics.

Single Diodes Replacement Considerations

Consult official cross-reference lists for verified equivalents. Generic replacements may differ in leakage current or forward voltage specifications. Verify pinout and package dimensions match the DO-35 form factor before substitution.
