New surge suppression portfolio offers a lower cost of design

19-02-2020 | RS Components | Semiconductors

RS Components is now stocking a large portfolio of TVS Flat devices, manufactured by STMicroelectronics. Designed to handle 8/20µs and 10/1000µs voltage transients and protect circuits and equipment from power surges, the company’s portfolio of Electrical Over-Stress TVS Flat devices incorporates industrial and automotive-grade devices. Achieving a lower cost per watt ratio, the portfolio variants are only 1mm thick and footprint compatible with standard surface-mount devices including SMA (400W and 600W types) and SMB (600W) style packages.

The range allows design engineers to achieve the same level of protection and save costs by utilising, for example, a smaller 600W SMA Flat device rather than a larger standard SMB style component. Both devices can manage 600W. This indicates these devices can be a serious alternative for designers in a broad range of applications including solar inverters and industrial control applications.

The components are ideal for thinner designs and also suitable for usage in circuitry for DC line, MOSFET and IGBT protection circuits in a wide range of market sectors, including motor control, power tools, e-bikes and telecommunications, as well as consumer devices or equipment such as hard-disk drives.

Producing increased power density, they also provide a maximum junction temperature (TJ max) of up to +175C, meeting or exceeding international standards to protect sensitive equipment against EOS and ESD.
