Procurement Notes

Verify the specific ordering code suffix against official Infineon documentation to confirm quality level and packaging details. Ensure compatibility with the required thermal management specifications, as derating is necessary when the soldering point temperature exceeds 104°C. Confirm that the component meets the necessary radiation hardness requirements for the intended mission profile.

Selection Notes

Select this transistor for applications requiring high reliability in space or harsh environments where hermetic sealing is mandatory. Consider the 12 V collector-emitter voltage limit and 80 mA maximum collector current when designing bias circuits. Evaluate the thermal resistance characteristics to ensure adequate heat dissipation within the operating temperature range of -65°C to +200°C.
