High-Current Photorelay accelerates mechanical relay replacement.

Press Release Summary:

May 08, 2014 - Supplied in 2.54SOP6 package, TLP3107 consists of photo MOSFET optically coupled to IR LED. On-state resistance of 0.04 Ω typ (0.07Ω max) and permissible on-state current (3.3 A max) make this normally off (1-Form-A) photorelay suited to testing applications, including power-line switching, feedback resistance switching and measuring-line switching. Specifications include 3.3 A max output, 60 V min off-state output terminal voltage, 3 mA max trigger LED current, and 1,500 Vrms min isolation voltage.

Original Press Release

New High-Current Photorelay from Toshiba Suited for Testing, Control Applications

Press release date: Apr 29, 2014

Enhances Performance; Reduces Mounting Area

IRVINE, Calif. – Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced a new small package size, high-current (3.3A max.) photorelay - the TLP3107.  Housed in a small 2.54SOP6 package, the low on-state resistance and high permissible on-state current of the TLP3107 make it suited to testing applications, including power-line switching, feedback resistance switching and measuring-line switching.

Photorelays provide design engineers with fast switching speed, high reliability, lower power consumption, and noise-free operation in a space-saving package, making them an alternative to mechanical relays.  Consisting of a photo MOSFET optically coupled to an infrared light emitting diode, the new photorelay utilizes the latest generation trench MOSFET to realize an approximately 1.4 times higher on-state current than Toshiba's existing product, the TLP3103.  This performance, combined with a 3.3A (max.) output, will accelerate the replacement of mechanical relays in applications that require high density assembly.  Replacing a 3A-capable DIP package with the 2.54SOP6 package reduces the assembly area by 40 percent, and the overall product height by half.
