Procurement Notes

Verify the specific suffix AC against official datasheets to confirm binning or testing criteria. Ensure compatibility with standard SOT-89 footprint dimensions during PCB layout. Confirm lead-free status and RoHS compliance requirements match target market regulations before finalizing procurement specifications.

Selection Notes

Select this component when a PNP transistor with 80 V breakdown and 1 A current handling is required in a small surface-mount package. Consider thermal dissipation limits at elevated ambient temperatures. Compare saturation voltage and switching speed against alternative SOT-89 PNP devices for optimal circuit performance.

Part Context

The 2SA1523 series belongs to onsemi's lineup of PNP epitaxial planar silicon transistors. These devices are engineered for reliability in high-volume consumer and industrial applications. The AC suffix typically denotes specific electrical parameter bins or testing standards defined by the manufacturer for quality assurance purposes.

Replacement Considerations

Direct substitutes include other PNP transistors in SOT-89 packages with comparable VCEO and IC ratings. Verify pinout compatibility and thermal resistance values before implementation. Alternative part numbers may require circuit adjustment if saturation voltages differ significantly.
