It supports a maximum continuous collector current of 500 mA and features a minimum DC current gain of 2000. The device withstands a maximum collector-emitter voltage of 60 V and a collector-base voltage of 80 V. Power dissipation reaches 1 W, with a maximum operating temperature of +150 °C. Electrical limits include a base-emitter saturation voltage of 1.5 V max and collector-emitter saturation voltage of 1 V max.

Feature Summary

• High current amplification capability provided by the Darlington configuration.

Applications

• General-purpose switching applications
• Driver circuits for loads requiring high input impedance

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific suffix matches the required packaging format. Check for end-of-life status as discontinuation notices may apply. Ensure storage conditions comply with moisture sensitivity levels before soldering. Validate that the procurement source provides traceable documentation for quality assurance purposes.

Selection Notes

Select this component when high current gain is required in a compact surface-mount footprint. The SOT-89 package offers thermal performance suitable for moderate power dissipation. Consider the 60 V rating for low-voltage switching tasks. Evaluate the 500 mA limit against load requirements to ensure safe operation within specified junction temperatures.

Part Context

This part belongs to Infineon's discrete semiconductor portfolio, specifically designed for general-purpose amplification and switching. The SOT-89 housing facilitates automated assembly processes. As a Darlington pair, it integrates two transistors to achieve superior beta values compared to single BJT devices, simplifying drive circuit design for medium-current loads.

Replacement Considerations

Consult official Infineon substitution guides for verified alternatives. Cross-reference pinouts and electrical ratings carefully. Generic equivalents may not match the specific gain binning or thermal characteristics of the original component.
