Procurement Notes

Verify the specific datasheet version and revision history prior to procurement, as Renesas Electronics may update specifications over time. Confirm that the component meets RoHS compliance standards if required by your manufacturing process. Note that this part number is associated with legacy NEC Electronics technology now managed by Renas. Ensure that the ordering suffix matches the exact packaging and tape-and-reel specifications required for your automated assembly line. Cross-reference with official Renesas documentation to confirm current lifecycle status and availability constraints.

Selection Notes

Select this component when designing RF circuits requiring high linearity and low noise figures in the 2.4 GHz range. Consider the 2 V drain-source voltage limit when determining power supply requirements for the amplifier stage. Evaluate the thermal management capabilities of the small outline package against the expected power dissipation in your specific application environment. Compare the 10 mA current rating against the biasing requirements of your system architecture to ensure stable operation without exceeding absolute maximum ratings.

Part Context

This transistor belongs to the NE350x series of HJ-FETs developed originally by NEC Electronics Corporation before its merger with Renesas Technology Corporation. The M04 designation indicates a specific pinout and package variant within this family. These devices are widely recognized in the telecommunications industry for their reliability in microwave frequency applications. The transition from NEC to Renesas ensures continued support and documentation availability for existing designs utilizing this semiconductor technology.

Replacement Considerations

Check for direct substitutes such as the NE3503M04 or NE3508M04 variants, which share similar HJ-FET architectures but may differ in specific frequency optimization or pin configurations. Verify compatibility with existing PCB footprints and biasing networks before substituting. Consult official Renesas cross-reference guides to identify approved replacements that maintain equivalent RF performance metrics.
