www.MICROSEMI.com SM0502 SM1003 SM0502 SM1003 CONTROL DEVICES TM Surface Mount MELF PIN Diodes RoHS Compliant Versions DESCRIPTION KEY FEATURES 1 This line of MELF high power PIN diodes are hermetically sealed Non-Magnetic Versions Ideal for surface mount packaged devices with full face bonded chips for low MRI Applications inductance construction. The MELF ceramic package has square end Very Low Inductance, Full Face terminations which are ideal for surface mount and pick and place operations. The PIN diode chips are coated with a special hard glass Bonding passivation which is required for high power applications and to Hi-Rel Hermetic Design enhance the reliability resulting in MTBFs of greater than one million Surface Mount Devices Available hours. in Tape and Reel RoHS compliant versions of these products meet RoHS requirements per EU 2 RoHS Compliant Versions Directive 2002/95/EC. The standard terminal finish is gold unless otherwise specified. Consult the factory if you have special requirements. Available APPLICATIONS The MELF diodes are used as switching, attenuating and phase shifting elements from HF through 2 GHz and have breakdown APPLICATIONS/BENEFITS 1 voltage ratings up to 500 volts. Non-magnetic .Cer-Met. (MELFs) Designed for Low Loss Low are also used as switching elements in MRI (magnetic resonance Distortion Applications imaging). Conventional Magnetic MELF packages are used in Cellular, Beam Steering units (telephone via satellites) surface mount Switch Filter Bank applications, and Filter Switch banks for Frequency Hopping Radios.
