BLF0910H6L500U

Overview

The BLF0910H6L500U is a 500 W LDMOS power transistor designed for high-power continuous wave applications at 915 MHz. It operates with a drain-source voltage of 50 V and achieves a typical drain efficiency of 61% at Tcase = 65 °C. The device provides a power gain of 18 dB under these conditions. It features an internally matched input and is housed in a flanged ceramic SOT502A package with two mounting holes.

Feature Summary

• High efficiency performance
• Easy power control capability
• Excellent ruggedness characteristics
• Integrated ESD protection

Applications

• Industrial applications in the 915 MHz ISM band

Procurement Notes

Verify the specific ordering suffix against official Ampleon documentation to confirm the exact package variant, as the 'U' designation may indicate tray packaging or specific handling requirements distinct from standard bulk configurations. Confirm RoHS compliance status directly with the manufacturer's current product data sheet before finalizing procurement specifications.

Selection Notes

Select this component for broadband operation between 900 MHz and 930 MHz where high power output is required. Ensure the application circuit supports Class-AB biasing with a quiescent current of approximately 90 mA. Verify that the thermal management system can maintain the case temperature at 65 °C to achieve the specified 500 W output power rating.

Part Context

This part belongs to the BLF0910H6 series of power LDMOS transistors manufactured by Ampleon. It shares similar electrical characteristics with the BLF0910H6LS500 but utilizes the SOT502A package, which includes mounting holes, whereas the LS500 variant uses the earless SOT502B package. Both are intended for industrial RF power amplifier designs.

Replacement Considerations

The BLF0910H6LS500 is a direct functional equivalent within the same family, differing only in the physical package type (SOT502B vs SOT502A). Designers must verify mechanical fit and mounting hole alignment when substituting between these variants.
