SEMI-SCALETM PIN Diodes
MSSP25250-70 Series Datasheet
Description
The MSSP25250-70 SEMI-SCALETM PIN Diode is manufactured using Aeroflex/Metelics proprietary diode
process which provides an ultra-low parasitic PIN Diode in a 0603 Surface Mount package.
This proprietary and unique geometry offers lower electrical and thermal resistance to provide higher
average power performance to comparable surface mount diode packages. The low RC product
( < 0.35 pS ) and ultra-low parasitic Ls ( < 0.15 nH ) and Cpar ( < 0.025 pF ), optimize control circuit
frequency performance for series or shunt diode configurations.
With lower Thermal Resistance ( < 30 C/W ), RF C.W. incident power levels of + 40 dBm and RF peak
incident power levels of +55 dBm are very achievable in higher power cold and hot switching
applications. The low series resistance ( < 1.2
Ω ), coupled with the longer minority carrier lifetime,
( > 500
ηS ), provides better IIP3 distortion values > + 85 dBm, for RF and Microwave Switches.
Applications
The MSSP25250-70 SEMI-SCALETM PIN Diode is designed to be used in Series, Series-Shunt, and Shunt
Configurations in Higher Power Switch and Attenuator applications, operating from 10 MHz to 6 GHz,
requiring high volume, surface mount manufacturing. These devices are durable, reliable, and are
capable of meeting all military, commercial, and industrial applications. The devices are fully RoHS
compliant.
Environmental Capabilities
The MSSP25250-70 SEMI-SCALE
TM PIN Diode is capable of meeting the environmental requirements of
MIL-STD-202, MILSTD-750, and MIL-STD-883..
ESD Rating
PIN Diodes are susceptible to ESD conditions as with all semiconductors. The ESD rating for these
devices is Class 1A, HBM.
