HSMP-389x Series, HSMP-489x Series
Surface Mount RF PIN Switch Diodes
Data Sheet
Description/Applications
The HSMP-389x series is optimized for switching appli-
cations where low resistance at low current and low ca-
pacitance are required. The HSMP-489x series products
feature ultra low parasitic inductance. These products
are specifically designed for use at frequencies which
are much higher than the upper limit for conventional
PIN diodes.
Features
• Unique Configurations in Surface Mount Packages
– Add Flexibility
– Save Board Space
– Reduce Cost
• Switching
– Low Capacitance
– Low Resistance at Low Current
• Low Failure in Time (FIT) Rate
