RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package variant and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment regarding the SOD-323FL footprint dimensions. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a low-capacitance PIN diode is required for frequencies around 1 MHz or higher. Compare the 60 V reverse voltage rating against peak circuit voltages to ensure adequate margin. Evaluate the 3 Ohm series resistance impact on insertion loss relative to system performance requirements.

RF Diode Part Context

This part belongs to ROHM's UMD2 (SOD-323FL) family of small-signal diodes. It serves as a surface-mount alternative to larger through-hole packages, facilitating miniaturization in portable electronic devices. The designation indicates a standard commercial grade product intended for general-purpose RF switching tasks.

RF Diode Replacement Considerations

The RN142VM is listed as a similar level replacement with the same pinout and package. Verify electrical parameter tolerances and marking codes before substituting to ensure functional equivalence in existing designs.
