Datasheet CR0640SA DatasheetCR0640SA Datasheet (PDF)

CRxxxx series Description The CR range of protectors are based on the proven technology of the T10 thyristor product. Designed for transient voltage protection of telecommunications equipment, it provides higher power handling than a conventional avalanche diode (TVS) and when compared to a GDT offers lower voltage clamping levels and infinite surge life. Packaged in a transfer molded DO-214AA surface mount outline designed for high speed pick & place machines used in today’s surface mount asse.

Electrical Charecteristics The electrical characteristics of a CRXXXX device is similar to that of a self gated Triac, but the CR is a two terminal device with no gate. The gate function is achieved by an internal current controlled mechanism. Like the T.T.S. diodes, the CRXXXX has a standoff voltage (Vrm) which should be equal to or greater than the operating voltage of the system to be protected. At this voltage (Vrm) the current consumption of the CRXXXX is negligible and will not effect the protected system. When a transient occurs, the voltage across the CRXXXX will increase until the breakdown voltage (Vbr) is reached. At this point the device will operate in a similar way to a T.V.S. device and is in an avalanche mode. The voltage of the transient will now be limited and will only increase by a few volts as the device diverts more current. As this transient current rises, a level of current through the device is reached (Ibo) which causes the device to switch to a fu.
