Smallest Package In The Industry*

PL_movie_2

Toshiba's Photorelay package lineup includes several families in the extremely small VSON series.  The smallest solution available in the industry today is the S-VSON4 package, which has 2mm x 1.45mm mounting area and a high operating temperature of up to 110degC.  If you have space constraint and need a lot of photorelays on your board, the S-VSON/VSON series are the best solution.
This small package size is made possible by Toshiba's unique Chip on Chip (COC) technology.

A long life, maintenance-free

PL_movie_3

Mechanical relays experience much wear and tear, but by switching to photorelays we can address that concern.  Photorelays are a maintenance free solution with no mechanical contact or wear and tear, which will provide a longer life and higher reliability.  Without repair and replacement costs you can save on the total cost.

A Product Lineup To Match Your Needs

PL_movie_4

The graph shows the photorelay and signal relay (a kind of mechanical relay, below 2A contact capacity) coverage area.  Toshiba's high capacity (current) photorelays can cover almost all areas of signal relays and address high current applications.  Toshiba photorelays adopt the latest generation of Toshiba’s own MOSFETs.  At the moment the TLP3547 offers the highest current of 5A  at 60V, and the TLP3543A at 30V in a DIP package which is smaller than an SIL package.  Toshiba also have various types of low input current type devices (TLP176AM,TLP172GM), a high break down voltage (BVs)-5kVrms series (TLP240, TLP241), plus the very small VSON4 series suitable for automatic tester equipment.
