The new Microsemi MOSFETs are gold-metallized silicon n-channel RF power transistors with 25% lower thermal resistance and 30% higher power dissipation than is available in industry standard M174 packages.

The new VRF151E and VRF152E are capable of operating up to 175MHz, and the VRF190E is capable of operating up to 150MHz. They are drop-in replacements for SD2931-10, SD2941-10 and SD3931-10 transistors respectively.

Key Performance Features:

  * 30% higher power dissipation than standard packaging
  * Higher BV than competitive parts for increased ruggedness
  * High VSWR
  * Nitride passivated and gold metallization for improved
    reliability
  * Lead-free construction

The 500-piece pricing of the VRF151E is $45.63; the VRF152E, $56.34; and the VRF190E, $67.82. Contact the factory or authorized sales contacts for other quantities and delivery. Devices are available for immediate sampling. Technical information is available on the Microsemi web site, http://www.microsemi.com. Samples can be ordered through this site, or from Microsemi sales representatives and authorized distributors.
