STMicroelectronics has launched a range of transient voltage suppression TVS diodes that handle 600W and 1500W transient power in SMB Flat, and 400W and 600W in SMA Flat packages that are 1.0mm high.

In addition to the lower profile, the 1500W SMB Flat package has transient-power capability equivalent to that of conventional devices in SMC packages, in a footprint half the size. The 400W and 600W SMA Flat and SMB Flat devices are fully footprint-compatible with alternatives in conventional SMA and SMB packages. Leakage current is five times lower compared with other TVS diodes on the market, minimizing impact on system operation and power consumption.

The family of lower-profile, higher-power TVS diodes covers standoff voltages from 5.0V to 188V, to serve applications such as telecom equipment, consumer products, power tools, e-bikes, drones, robots, and automotive electronics. Industrial-grade and AEC-Q101 automotive-qualified parts are available, offering the most extensive selection on the market.

The 400W and 600W TVS diodes are in production now at prices starting from $0.06 for orders of 1000 pieces. 1500W diodes are available in sample quantities and will enter production in early 2020. All packages feature wettable flanks that facilitate automatic optical inspection (AOI) for efficient production-quality control.
