RF power LDMOS for 512 MHz band
The NXP MRFE6VS25GNR1 is an LDMOS RF power transistor designed for 512 MHz operation, delivering 25 W output with 25.4 dB gain at a 50 V test supply. The 133 V rated drain-source breakdown gives headroom for load mismatch and high-VSWR conditions common in RF power amplifier output stages. The TO-270-2 GULL package is a surface-mount, gull-wing leaded case with a large backside source tab for thermal conduction to the PCB ground plane. The 10 mA test current is typical for small-signal gain characterization; actual bias current in class-AB operation will be higher.
Gain and power — what they mean for the PA stage
The 133 V rated voltage means the device can survive transient overvoltage events up to that peak without avalanche failure, provided the thermal limit is respected. This is a ruggedness spec, not a continuous operating point.
Package and mounting — TO-270-2 GULL
The TO-270-2 GULL surface-mount package has two gull-wing leads plus a large source tab on the bottom. The tab must be soldered to a thermal-via array under the part to keep the junction temperature within limits at 25 W continuous output. The package footprint is smaller than a flanged bolt-down TO-272, saving board area in dense PA arrays. Cut Tape (CT) and Tape & Reel (TR) options are available for different assembly volumes. The surface-mount format suits automated pick-and-place lines, though the large tab may need a longer reflow profile for complete solder wetting.
Lifecycle and compliance
The MRFE6VS25GNR1 is listed as Active in production status and ROHS3 compliant. No end-of-life notification or last-time-buy window has been published. This is a current-design-in part for new RF power amplifier projects, not a phase-out risk.
