The Bourns TBU-DT065-200-WH is a Unidirectional Transient Blocking Unit (TBU) specifically designed to provide robust overvoltage and overcurrent protection for sensitive electronics. It features a voltage breakdown rating of 650V and a current limiting threshold of 300V, offering reliable protection against transient voltage spikes and power surges. With its ultrafast response time of 1 microsecond, the TBU-DT065-200-WH safeguards components and circuits from damage caused by voltage transients. This surface-mount device (SMD) is housed in a compact DFN package for convenient integration into space-constrained designs. Available in tape and reel packaging (T/R), the TBU-DT065-200-WH is an ideal choice for applications in industrial, automotive, telecommunications, and consumer electronics.
