| 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 OC.

These dimensions will match the terminals and provide for additional solder fillets at the outboard ends at least as wide as the terminals themselves, assuming accuracy of placement within 0.005" 2. If the mounting method chosen requires use of an adhesive separate from the solder compound, a round (or square) spot of cement as shown should be centrally located.
