Toshiba Electronic Devices & Storage Corporation ("Toshiba") has introduced two photocouplers, “TLP5705H” and “TLP5702H,” housed in a thin SO6L package, for use as insulated gate drivers for small to medium capacity IGBTs/MOSFETs. Volume shipments start today.

TLP5705H is Toshiba’s first product to deliver a peak output current rating of ±5.0 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 will contribute to parts reduction and set miniaturisation.
TLP5702H has a peak output current rating of ±2.5 A. An SO6L package that can be mounted on the land pattern of Toshiba’s conventional SDIP6 package [1], facilitating easy replacement of Toshiba’s current products [2]. The SO6L is thinner than SDIP6, which brings greater 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 ºC (Ta=-40 to 125 ºC), making it easier to design and maintain temperature margins.
Toshiba’s line-up also includes TLP5702H(LF4) and TLP5705H(LF4), housed in an SO6L(LF4) package as a lead-forming option.
