Special Investigation

The TCP1.25

-R is designed to provide overcurrent protection for telecom SLIC, xDSL modem, and set-top box applications regardless of

the overvoltage device selected. To provide an easier specification experience, Cooper Bussmann and STMicroelectronics have joined

together to provide a special test report confirming the coordination between the TCP1.25A and SMP100MC-270 devices.
