Taiwan Semiconductor has introduced new 24-volt automotive-grade SUPER CLAMP transient voltage suppression (TVS) devices designed to protect sensitive electronic circuits from voltage transients. The devices feature low clamping voltage, high peak pulse current capability, and compact surface-mount packaging to support space-constrained automotive designs.
The SUPER CLAMP family offers snapback operation that enables lower clamping voltage and higher surge current capability than conventional TVS diodes. This allows engineers to simplify circuit protection schemes, potentially reducing the number and cost of components required while maintaining reliability.
The new devices are available in SMC (LSMC24CAH) and SMB (LSMB24CAH) surface-mount packages, joining the broader SUPER CLAMP lineup that includes DO-214AB (SMC), DO-214AA (SMB), and DO-218AB versions. With peak pulse current ratings up to 300 A, the devices offer a high margin of system protection compared to standard TVSs, as well as greater durability than metal-oxide varistors (MOVs) or gas discharge tubes (GDTs), which can degrade after repeated surges. When operated within thermal limits, the SUPER CLAMP technology is designed for long service life without significant performance loss.
The devices are suitable for applications requiring 24-V surge protection in automotive systems and other industrial environments where compact, surface-mount protection is preferred. Datasheets, SPICE models, and CAD resources are available to support design integration.
Samples are currently available through DigiKey and Mouser, with production lead times of 8 to 14 weeks after receipt of order.
