Toshiba TLP5705H and TLP5702H photocouplers

Toshiba Electronic Devices & Storage has introduced two photocouplers, the TLP5705H and TLP5702H, housed in a thin SO6L package, for use as insulated gate drivers for small- to medium-capacity IGBTs/MOSFETs.

The TLP5705H is the company’s first product to deliver a peak output current rating of ±5 A in a thin package (SO6L) only 2.3 mm (max) high. As a result, devices such as small- to medium-capacity inverters and servo amplifiers that use a buffer circuit for current amplification can now drive their IGBTs/MOSFETs directly from the photocoupler, without any need of the buffer circuit. This should contribute to parts reduction and set miniaturisation.

The TLP5702H has a peak output current rating of ±2.5 A. An SO6L package can be mounted on the land pattern of Toshiba’s conventional SDIP6 package, facilitating easy replacement of the company’s current products. The SO6L is thinner than the SDIP6, which brings flexibility to component layouts on boards and also allows it to be mounted on the back of a board or used where new circuit design imposes limits on available height.

Both photocouplers have a maximum operating temperature rating of 125°C, making it easy to design and maintain temperature margins. They are suitable for use in industrial equipment such as industrial inverters, AC servo drives, PV inverters, UPSs, etc.
