Applications • Designed for switching applications Features • Low capacitance • Low resistance • Fast switching • Oxide-nitride passivated • Durable construction • High voltage PIN Beam-Lead Diodes Skyworks series of silicon PIN beam-lead diodes offer excellent performance in high frequency hybrid circuit switches. These devices are configured as mesa (DSM8100-000) or planar diodes (DSG9500-000), both of which have extremely low junction capacitance, 25 pF maximum, which enables these devices to be used has high-isolation series elements in high frequency switches. Both devices offer very fast switching time and low insertion loss. Skyworks broad product portfolio includes PIN diodes as beam-leads, in addition to packaged and bondable silicon chips, and plastic packaged surface mount devices for switch and attenuator applications. Applications PIN diodes are three layer diodes, comprised of a heavily doped anode (the “P” layer) and a heavily doped cathode (the “N” layer) separated by a virtually undoped intrinsic layer (the “I” layer). Under forward bias, charge carriers from the P and the N layers are forced into the I layer, which reduces its RF impedance. When a reverse bias voltage is applied across the PIN diodes, all free charge carriers are removed from the I layer, thereby causing its RF impedance to increase. This variable RF impedance versus DC or low frequency bias signal allows the diode to be used in RF switching circuits in which the PIN diode is either forward biased or reverse biased. Skyworks Green™ products are RoHS (Restriction of Hazardous Substances)compliant, conform to the EIA/EICTA/JEITA Joint Industry Guide (JIG) Level A guidelines, are halogen free according to IEC-61249-2-21, and contain <1,000 ppm antimony trioxide in polymeric materials.

Reverse current is specified at 10 μA maximum at the voltage rating. It is not recommended to drive a PIN diode into avalanche breakdown. Permanent damage to the diode is likely to occur. Switching The circuit below shows a pair of PIN diodes used to form a single pole, double throw switch. In this switch, a positive control current typically of the order of 10 mA is applied to one of the bias inputs to place that side of the switch into its low insertion loss state, while a negative bias voltage is applied to the other bias input, forcing the diode on that side of the switch into its maximum RF impedance state to produce high isolation on that side of the switch. Many other switching circuit variations exist. Please refer to “Design with PIN Diodes,” available at www. skyworksinc.com for more information.
