Latest trench MOSFET process delivers replacement for mechanical relays
Toshiba Electronics Europe has announced the launch of a new photorelay in a small 2.54SOP4 package that is just 2.1 mm high with a 2.54 mm pitch.
Fabricated using the latest U-MOS VIII trench MOSFET process, the new TLP3145 combines an off-state output terminal voltage of 200 V with a controllable on-state current of up to 0.4 A continuously or 1.2 A when pulsed. This makes TLP3145 a suitable replacement for a 1 A mechanical relay that is used to control 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. The TLP3145 is conveniently rated for an operating temperature range of -40 °C to +110 °C, making it easier to allow for a temperature margin in system-level thermal design.
The TLP3145 turns on or off in just 0.5ms (max.) and consumes a max. of 1 μA in its OFF-state. The new device offers an isolation voltage of 1500 Vrms and is approved to the UL1577 Safety Standard.
Notes:
The latest Gartner market report recognises 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 deliver products that meet the needs of customers by promoting the development of a diverse portfolio of photocouplers and photorelays tailored to market trends.
