TBU-CA025-050-WH Description

Short technical summary and product information.

The Bourns TBU-CA025-050-WH is a TBU high-speed protector from the TBU-CA series. It is constructed using MOSFET semiconductor technology and designed to protect against faults caused by short circuits, AC power cross, induction, and lightning surges. The device monitors current and triggers at 50 mA (typical) to provide an effective barrier, blocking surges up to 250 V peak impulse (duration <10 ms) and continuous AC RMS voltage of 100 V. It offers ESD protection of ±2 kV per IEC 61000-4-2. The TBU-CA025-050-WH is housed in a surface mount DFN package measuring 6.50mm x 4.00mm, suitable for automated assembly. It operates over a temperature range of -55°C to +125°C and is RoHS compliant and Pb-free. Typical applications include voice/VDSL cards, protection modules, process control, test and measurement equipment, and general electronics.
