Bourns, Inc. TVS Diodes TBU-CA065-100-WH

The Bourns TBU-CA Series High-Speed Protector IC (part number 83R7178) is designed for effective surge protection in electronic circuits. It features a peak impulse voltage withstand of 300V AC and operates within a continuous AC RMS voltage of up to 300V. The device utilizes MOSFET technology to monitor current and trigger protection against overvoltage and overcurrent conditions, effectively safeguarding sensitive components from faults caused by short circuits, AC power cross, induction, and lightning surges. This surface mount device is housed in a DFN package and is compliant with RoHS standards, ensuring it meets environmental regulations. The operating temperature range is from -55¬8C to +125¬8C, with a maximum junction temperature of +125¬8C. The TBU-CA device transitions to a protected state within approximately 1 microsecond when the current exceeds its trigger level, providing rapid response to surge events. It also features a reset voltage below which the device returns to normal operation, making it suitable for various applications including voice/VDSL cards, protection modules, and general electronics.
