Toshiba releases high-peak output current photocouplers

Toshiba Electronic Devices & Storage Corporation 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 have already begun.

TLP5705H is Toshiba’s first product to deliver a peak output current rating of ±5.0A in a thin package (SO6L) of only 2.3mm (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 miniaturization.

TLP5702H has a peak output current rating of ±2.5A. An SO6L package that can be mounted on the land pattern of Toshiba’s conventional SDIP6 package, facilitating easy replacement of Toshiba’s current products. 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 125º C (T_a=-40 to 125º C), 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.
