P40-G Series TBU ? High-Speed Protectors
Transient Blocking Units - TBU ? Devices
Bourns ? Model P40-G products are high-speed bidirectional
protection components, constructed using MOSFET semicon-
ductor technology, designed to protect against faults caused by
short circuits, AC power cross, induction and lightning surges.
Agency Approval
UL recognized component File # E315805.
Industry Standards
Description
Model
The TBU ? high-speed protector, triggering as a function of
the MOSFET, blocks surges and provides an effective barrier
behind which sensitive electronics are not exposed to large
