200 V, 0.4 A small photorelay: TLP3145
2017-12-15 | Return
“TLP3145” is a photorelay featuring an OFF-state output terminal voltage of 200 V and an ON-state current of 0.4 A in the small 2.54SOP4 package.Fabricated using the latest U-MOS VIII trench MOSFET process, the new photorelay combines an OFF-state output terminal voltage of 200 V with a controllable ON-state current of up to 0.4 A. This makes TLP3145 a suitable replacement for a 1-Form-A mechanical relay in control of a 100 V AC circuit. Replacing a mechanical relay with a photorelay that is smaller and does not need a relay driver increases system reliability and supports space-saving design. In another plus, the TLP3145 is rated for an operating temperature (max) of 110°C, making it easier to allow for a temperature margin in system-level thermal design.
The latest Gartner market report recognizes Toshiba as the leading manufacturer of optocouplers by sales in 2015 and 2016, with 23 % of sale-based market share in CY2016. (Source: Gartner, Inc. “Market Share: Semiconductor Devices and Applications Worldwide 2016” 30 March, 2017)
Toshiba Electronic Devices & Storage Corporation will continue to develop products that meet the needs of customers by promoting the development of a diverse portfolio of photocouplers and photorelays tailored to market trends.
