• Qualified for automotive applications under the AEC-Q101 standard
• Designed for high thermal performance with a 150 °C operating temperature capability

Applications

• Automotive power distribution systems
• Motor control circuits requiring half-bridge topologies
• Body actuation mechanisms

Procurement Notes

Verify the specific ordering suffix AKSA1 against official Infineon documentation to confirm exact packaging and reel specifications. Ensure that the procurement channel provides valid traceability records required for automotive-grade components. Cross-reference the part number with the latest datasheet revision to confirm compliance with RoHS standards and environmental directives before finalizing orders.

Selection Notes

Select this component when a robust half-bridge solution is needed for automotive environments. Consider the asymmetric voltage ratings (-30 V P-channel vs. 55 V N-channel) during circuit design. Evaluate the thermal resistance values (1.3 K/W junction-to-case for P-channel, 1.8 K/W for N-channel) to determine appropriate heatsinking requirements for the intended load conditions.

Part Context

This component belongs to the OptiMOS product family, which utilizes advanced planar trench gate technology. The integration of both channel types simplifies the design of motor drivers and switching applications by reducing the component count compared to discrete solutions. The TO220 package facilitates efficient heat dissipation through direct mounting to a heatsink.

Replacement Considerations

Consult the official Infineon cross-reference tools or application notes for verified substitutes. Do not assume compatibility based solely on package similarity; verify electrical parameters such as RDS(on), breakdown voltages, and thermal characteristics against the original specifications.
