Used with
TBU? Series
The 2020 T Series and Bourns? TBU? High-Speed Protectors are an ideal protection solution for a broad number of
industrial applications as well as telecom applications requiring GR-1089 or ITU-T K.21 compliance. The Bourns?
2020 T Series is also available with an optional fail-short mechanism for applications requiring UL safety standard
compliance.
These GDT devices provide coordinated overvoltage protection for the speci?ed TBU? protector models shown in
the above table. Together, the GDT and TBU? protectors provide extremely fast overcurrent protection (OCP) and
overvoltage protection (OVP) against electrical transients. When exposed to a transient event, the TBU? protector
will transition into a current-blocking condition in less than one microsecond at the rated current. When needed,
the GDT will transition into conduction at a voltage below its maximum impulse rating, protecting the TBU?
device from overvoltage and shunting the excess surge energy to ground. Once the transient subsides, the GDT and
TBU? device will reset to their normal off-state modes of operation.
The new models are available as RoHS* compliant. The product data sheet with detailed speci?cations can be
viewed on the Bourns website at www.bourns.com. Please contact your local Bourns Representative or Bourns
