High frequency signal transmissive photorelays with industryʼs-smallest mounting area: TLP3440S, TLP3475S

Product News 2017-10

S-VSON4、S-VSON4T

“TLP3440S” and “TLP3475S” are photorelays, featuring the industrysmallest mounting area[1].
The TLP3475S is housed in an S-VSON4 package and features low ON-state resistance. The TLP3440S is housed in a new S-VSON4T package, which has the same industry-leading smallest mounting area[1] as the
S-VSON4 but is thinner. The TLP3440S features low output capacitance.
The mounting area of the new packages is 22.5 % smaller than that of existing VSON4 packages[2]. By using in combination with both products, they will help to reduce the sizes of circuit boards for tester PEs[3].
The new products also can be used in gigahertz high speed signal transmissive lines. Unlike typical photorelays, which have a maximum operating temperature of 85°C, the TLP3440S and TLP3475S can operate at up to 110°C, and therefore simplify system design.
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, Inc. “Market Share:
Semiconductor Devices and Applications Worldwide 2016” 30 March, 2017)
Toshiba Electronic Devices & Storage Corporation will continue to develop products that meet the needs of customers by promoting the development of a diverse portfolio of photocouplers and photorelays tailored to market trends.
