RF Diode Procurement Notes

Verify the specific manufacturer datasheet for the UM7104D to confirm exact mechanical dimensions and pin configurations. Ensure compatibility with automated assembly processes if required. Check for RoHS compliance status as versions may vary. Confirm the hermetic seal integrity requirements against the application environment specifications before finalizing procurement.

RF Diode Selection Notes

Select the UM7104D when a hermetic silicon PIN diode with 600 V reverse voltage is required. Consider its 1.2 pF capacitance and 600 mOhm series resistance for high-frequency performance. Evaluate the -65 C to +175 C operating temperature range against system thermal constraints. Compare carrier lifetime specifications with alternative UM7000 or UM7200 series devices based on specific switching speed needs.

RF Diode Part Context

The UM7104D is part of the UM7100 series of high-power PIN diodes from Microchip Technology. This series offers a balance of moderate power handling and low parasitic elements. Unlike the UM7000 series which supports higher voltages up to 1000 V, or the UM7200 series with lower resistance but higher capacitance, the UM7100 series provides a distinct performance profile suited for specific RF and microwave circuit designs.
