Applications

Procurement Notes

Verify the specific suffix AS against official datasheets to confirm package type and marking specifications. Ensure compliance requirements such as RoHS status are confirmed via Material Composition Declaration documents provided by the manufacturer before procurement.

Selection Notes

Select this component for applications requiring high current gain and integrated protection features. Consider the monolithic construction for reliability and the integrated diode for simplified circuit design in switching or amplification roles.

Part Context

This part belongs to the Darlington transistor portfolio, which includes devices with voltage ranges up to 400 V and both NPN and PNP polarities. It is categorized under discrete semiconductors and power modules within the manufacturer's standard product lineup.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Generic replacements may not match the specific planar base island technology or integrated diode characteristics.
