Toshiba’s SO6L Package IC Photocouplers Now Have Option for Wide Leadform

May 17, 2017

New products realize direct replacement from current SDIP6(F type) package products.


TOKYO–Toshiba Corporation's (TOKYO: 6502) Storage & Electronic Devices Solutions Company is expanding its line-up of SO6L IC photocouplers with a new package type SO6L(LF4), the wide leadform option. The wide leadform option is available for three high-speed IC photocouplers and five IGBT/MOSFET driver photocouplers. Mass production shipments start today.

The new photocouplers are in a SO6L(LF4) package and can be mounted on land patterns of SDIP6(F type) products with a maximum height of 4.15mm. The SO6L(LF4)’s 2.3mm (max) thin package offers users the advantage of directly replacing SDIP6(F type) products in height-critical applications that require lower package height, such as a back of PCBs.

To support replacement of widely used original land pattern of SDIP6(F type) package products, Toshiba will expand the wide leadform option line-up for other SO6L IC photocouplers.

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 “Market Share: Semiconductor Devices and Applications Worldwide 2016” 30 March, 2016)

Toshiba 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.


High-speed communication photocoupler

  • Factory networking
  • High-speed digital interfacing for instrumentation and control devices
