PolySwitch Resettable Devices
Surface-mount Devices
PolySwitch surface-mount devices are the preferred
circuit protection method for computer, consumer,
multimedia, portable, and automotive electronics
applications.
In an effort to reduce the size and cost of surface mount
devices, we introduced the miniSMD product series in
1995. Subsequently, we developed the microSMD,
nanoSMD and picoSMD family of products. The picoSMD
series reduced the device size to a 2012mm (0805 mils)
foot print, one fourth the size of the popular miniSMD
series.
Recent additions to the PolySwitch surface-mount series
include 24V miniSMD 4532mm (1812 mils), 60V
decaSMD 5050mm (2018 mils), and 2.0A microSMD
3225mm (1210 mils) devices.
Benefits
• Smaller size saves board space and cost
• Many product choices give engineers more design
flexibility
• Compatible with high-volume electronics assembly
• Assists in meeting regulatory requirements
• Higher voltage ratings allow use in new applications
Features
• RoHS compliant
• Broadest range of resettable devices available in the
industry
• Current ratings from 0.05 to 3A
• Voltage ratings from 6V computer and electronic
applications to 60V telecom applications
• Agency recognition: UL, CSA, TÜV
• Small footprint
• Fast time-to-trip
• Low resistance

Applications
• Computer
• Portable electronics
• Multimedia
• Game machines
• Telephony and broadband
• Mobile phones
• Automotive
• Industrial controls
• Battery
