Toshiba Expands Line-up of Photorelays in Industry's Smallest Package

TOKYO--(BUSINESS WIRE)--Mar 31, 2015--Toshiba Corporation 's (TOKYO:6502) Semiconductor & Storage Products Company today announced that it will expand its lineup of photorelays in the industry's smallest [1] package, VSON4 [2], with the addition of six products that offer low off-state capacitance, low on-state resistance and high-voltage. These latest additions to the "TLP34xx series" start shipping today. By expanding the variation of voltage and "C x R", the photorelays can support a variety of applications including semiconductor testers, measuring equipment and medical equipment.

The new products have the same electrical characteristics as Toshiba's small-size package USOP4 series, but reduce required assembly area by approximately 50% [3] by using the industry's smallest package, VSON4. This can contribute to smaller and thinner products, and also makes it possible to significantly increase the number of photorelays on a circuit board without increasing its size.

The new line-up includes "TLP3442," which realizes the industry's lowest [4] off-state capacitance (C OFF ), 0.3pF (typ.), and "TLP3431," which is suited for use in high-frequency signal transmission with a low on-state resistance (R ON ) of 0.8ohm (typ.). The "TLP34xx series" provides a total system solution with a product line-up that covers both the low C OFF and low R ON range in an ultra-small VSON4 package.

Key Features of New Products:

VSON4 package: Thickness 1.3mm (max), Area 1.5mm??2.5mm (max.) Trigger LED current: 3 mA (max) Isolation voltage: 300 Vrms (min.)

Main Applications:

Automatic Test Equipment (ATE) Measuring instruments Medical equipment Reed relay replacement
