Procurement Notes

Verify the specific package variant required, as the datasheet covers both the straight lead SOT1223-2 (BLP05H635XR) and gull-wing SOT1224-2 (BLP05H635XRG). Confirm that the ordering suffix matches the desired physical pin configuration before finalizing procurement. Ensure compliance with Ampleon's terms and conditions regarding product suitability and liability.

Selection Notes

Select this component for designs requiring high power output in the HF to 600 MHz range. Consider the thermal resistance of 2.0 K/W and the maximum junction temperature of 225 °C when designing the heatsinking solution. Verify that the application environment does not exceed the absolute maximum ratings, particularly the 135 V drain-source voltage limit, to ensure long-term reliability.

Part Context

This part belongs to Ampleon's H635X series of power LDMOS transistors. The series is engineered for high-power density and ruggedness in demanding RF environments. The BLP05H635XRY shares core electrical specifications with other variants in the family, differing primarily in package style and manufacturing revisions.

Replacement Considerations

The datasheet lists BLP05H635XRG as a related variant with an identical electrical profile but a different gull-wing package (SOT1224-2). No other direct cross-model substitutes are documented in the provided source material.
