Toshiba TLP3480, TLP3481 and TLP3482 photorelays

Toshiba Electronic Devices & Storage has launched the photorelays TLP3480, TLP3481 and TLP3482 in P-SON4 — a package with a significantly smaller mounting area than the company’s SOP packages.

The P-SON4 package is suited to high-density mounting, as it has a mounting area of 7.2 mm² (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.

The 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 30 V and 4.5 A to 100 V and 2 A, according to the device. They can be used in a wide range of measuring equipment applications, including semiconductor testers (memory, SoC, LSI, etc), probe cards and I/O interface boards.
