All of the new photorelays have an OFF-state output terminal voltage rating and ON-state current rating comparable with products housed in SOP package products, with ratings ranging from 30V and 4.5A to 100V and 2A, according to the device.

The new P-SON4 package is highly suited to high-density mounting, as it has a mounting area of 7.2mm2 (typ.), approximately 74% smaller than the 2.54SOP4 package and 84% smaller than the 2.54SOP6 package. It also features low ON-resistance by using Toshiba’s latest MOSFET chips in the receiver.

TLP3480, TLP3481, and TLP3482 have high ON-state-current ratings of 4.5A, 3A and 2A. They can be used in a wide range of measuring equipment applications.
