UM7500
POWER PIN DIODES
DESCRIPTION
The UM7500 series features Microsemi’s
innovative passivated chip design which
takes advantage of the latest silicon wafer
bonding and junction passivation
techniques. This new series of PIN diodes
incorporates all of the desirable RF
properties of previous Microsemi diodes
plus extremely low leakages and very stable
reverse characteristics. Power dissipation
capability is assured by Microsemi’s
metallurgically bonded, fused in glass
construction. This technique continues to be
the optimum approach for applications
requiring reliable, high power diodes.
Low leakage distortion is achieved by
maintaining high carrier lifetime and accurately
controlling I-region thickness throughout the
process. The UM7500 series is designed for use
in a broad range of RF and microwave switch and
attenuator circuits. The packages make this series
suitable for many high-end medical applications
such as MRI and CAT scan equipment. For
military applications, the new series is capable of
meeting all the requirements of MIL-STD-750
including HTRB screening at 80% of rated
voltage at 150
