Optocoupler enables 30% saving on PCB real estate

Optocoupler enables 30% saving on PCB real estate
The first AEC-Q101 qualified, phototransistor optocoupler introduced by Vishay is now available at TTI. This newly-launched device, the VOMA617A, combines a high current transfer ratio (CTR) of 50% to 600% with low 5mA forward current. Supplied in a compact SOP-4 package, the new device offers the major advantage of a 30% saving on PCB real-estate when compared to a DIP-4 package.

IC photocouplers provide option for wide leadform

IC photocouplers provide option for wide leadform
With a new wide leadform package type SO6L(LF4), Toshiba Electronics Europe has expanded its line-up of SO6L IC photocouplers. The wide leadform option is available for three high-speed IC photocouplers and five IGBT/MOSFET driver photocouplers. The new photocouplers can be directly mounted on PCB pads intended for SDIP6(F type) products. The SO6L(LF4)’s 2.3mm (max.) low profile package offers a 45% height reduction over SDIP6(F Type) and allows use in height-critical applications, such as mounting on the underside of PCBs.

High current photorelay range expands with 60 and 100V products

High current photorelay range expands with 60 and 100V products
Two additions have been added to Toshiba Electronics Europe's line-up of photorelays; the 60V TLP3407S and the 100V TLP3409S. These devices are packaged in S-VSON4, the 2.00x1.45mm package with what it claims to be the industry's smallest mounting area. The new products realise high voltages while retaining the features of the existing TLP3406S, which offers a 30V rating with large on-state current rating and small size.
