TVS devices achieve ±3.5% breakdown voltage tolerance

TVS devices achieve ±3.5% breakdown voltage tolerance
Vishay Intertechnology has introduced a series of SMT TransZorb Transient Voltage Suppressors (TVS). Vishay General Semiconductor SMBJXXD series TVS achieve ±3.5% breakdown voltage tolerance and very low reverse leakage current. Compared to previous devices, the series offers excellent clamping features with higher peak pulse surge current and lower clamping voltage for better input protection of ICs.

Power line chokes' vertical design saves PCB space

Power line chokes' vertical design saves PCB space
Expanding its range of frame core power line chokes, TDK has introduced the B82733V* series in a vertical design, complementing the horizontally designed B82733F* series. The vertical design is particularly advantageous when there is limited space on the PCB. Featuring an insertion height of 27mm, the chokes have a footprint of just 29x15.5mm. This is more than 30% smaller than that of the horizontal version.
