TCP1.25A, Telecom Circuit Protector

TEST CIRCUITS

Special Investigation

The TCP1.25A 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.
