Bourns Announce Transient Current Suppressors Delivering Ultra-Fast, Cost-Effective And Reliable Circuit Protection

Bourns TCS devices are high-speed, bidirectional, low resistance, automatically resettable, compact current limiting devices that protect circuits from overcurrent surges. Protecting within nanoseconds, the devices are capable of significantly reducing latency common in most circuit protection designs, and limit the let-throughenergy that could potentially damage sensitive electronic circuits. A solution consisting of a TCS device and an overvoltage protector such as a clamping diode offers OEMs a superior overvoltage and overcurrent protection solution.

Bourns designed its innovative and ultra high-speed TCS devices to provide designers a high performance and cost-effective circuit protection alternative for sensitive xDSL and Gigabit Ethernet port line drivers, said Ian Doyle, product line manager for semiconductor products at Bourns, Inc. DSL and Ethernet interfaces are increasingly exposed to surge threats and Bourns TCS solutions reliably protect low voltage driver and receiver components from damage from lightning surges without compromising performance. The small footprint of these new devices simplifies retrofitting or upgrading of existing equipment at minimum redesign costs. In most cases, designers can simply add a TCS device to an existing TVS protection design.

The Bourns TCS DL-Series provides an integrated solution that minimizes board size, design and manufacturing costs for faster time-to-market. The new devices also help to reduce costly field failures and help end-users decrease expensive maintenance, repair and system downtime costs.

The Bourns TCS DL-Series are available now. As a pricing reference, a 2.3 Ohm dual TCS (TCS-DL004-250-WH) is priced at $0.42 each in 1000 piece quantities.
