Taiwan Semiconductor has introduced its new automotive-grade 24V SUPER CLAMP snapback TVS devices in compact SMC and SMB surface-mount packages.

SUPER CLAMP TVSs combine lower clamping voltages, higher peak pulse currents and lower-voltage ratings than conventional TVSs, according to the company. The snapback devices allow circuit designers to use fewer, less costly components without compromising circuit reliability.

The new devices in SMC (LSMC24CAH) and SMB (LSMB24CAH) package options can help further reduce PCB space.

The complete series is offered in three package types: DO-214AB (SMC), DO-214AA (SMB) and DO-218AB.

When used in compact surface-mount PCB layouts, SUPER CLAMP TVSs can reduce parts count and eliminate the need to overdesign to achieve automotive-level reliability.

Providing maximum pulse currents of up to 300 A, SUPER CLAMP TVSs provide a higher margin of system protection than alternative options, the company said.

Samples are available now and the lead time for production quantities is 8-14 weeks.

“As processor and other VCC voltages in automotive designs keep getting lower, the need for more precise and aggressive transient protection is needed to reduce parts count and to protect these sensitive electronics,” said Sam Wang, Vice President, TSC Products. “In addition to saving money and design time, the new SMB- and SMC-packaged SUPER CLAMP devices offer options for drop-in upgrades in space-limited designs where better protection is needed.”
