TBU-KE050-200-WH Description

Short technical summary and product information.

The Bourns TBU-KE050-200-WH is a high-speed surge protection component from the TBU-KE Series. It provides superior circuit protection against overcurrent and overvoltage faults, blocking surges up to its rated limits.

 

This unidirectional TBU device trips in less than 1 μs when current reaches its maximum value in one direction. It effectively shields sensitive electronics from large voltages or currents during surge events. After a surge, the device resets automatically when the voltage across it falls to the Vreset level.

 

Designed for surface mounting, the TBU-KE050-200-WH comes in a compact 2-DFN (2.5x5) package. Its internal switch technology and high-speed performance make it suitable for various applications requiring robust protection.

 

Key electrical specifications include a peak impulse voltage withstand of 500V and an RMS continuous AC RMS voltage rating of 250V. The operating temperature range is from -40°C to +85°C, with a storage temperature range of -65°C to +150°C.
