The CPC1510 is a single-pole, normally
open (1-Form-A) Solid State Relay with an
integrated current limit feature that can replace
electromechanical relays while enhancing the
robustness of wireline-interface applications.

Features
• Integrated active current-limit protection
• Thermal shutdown
• Linear AC or DC operation
• Low power consumption
• Clean, bounce-free switching
• High surge capability
• Low power drive requirements
• Surface mount version available
• Tape & reel packaging available
The relay is constructed using a GaAIAs LED for
actuation control and an integrated monolithic die for
the switch output. The die, fabricated in a
high-voltage dielectrically isolated technology,
comprises a photodiode array, switch control with
active current limiting circuitry, and MOSFET
switches. The active current limit circuitry in the
CPC1510 also provides a thermal shutdown feature
offering excellent power cross immunity for improved
survivability in harsh environments.
These enhancements greatly improve the robustness
of end systems using this device compared to
systems using relays without the integrated current
limit. In addition, the active current limit circuitry
enables the CPC1510 to pass FCC 68.302 and
other regulatory voltage surge requirements when
adequate overvoltage protection is provided. The
CPC1510 relay may be used in both unidirectional
DC applications as well as bi-directional AC
applications.
