Toshiba released a new photorelay-TLP3476S

With more than 50 years of experience and innovation, Toshiba Electronic Devices & Storage Corporation, a top provider of advanced semiconductor and storage solutions, provides customers and business partners with exceptional discrete semiconductors, system LSIs, and HDD products.

 

Toshiba announced the launch of a photorelay in the S-VSON4T package — “TLP3476S” on May 26. The turn-on time can be shortened to half of the company's existing product TLP3475S.

TLP3476S is faster and more compact than Toshiba's current TLP3475S. It realizes high efficiency optical coupling by improving the optical output of infrared LEDs and optimizing the design of photo detector devices (photodiode arrays). This improves operating speed and pushes turn-on time to a maximum of 0.25 ms -- 50% faster. It is also 20% slimmer, due to a smaller, low profile S-VSON4T package that is 1.4 mm at maximum. This helps to reduce the size of equipment that requires multiple boards.

 

Toshiba TLP3476S Optocoupler Photorelay is a high switching speed type of TLP3475S that contains an opto-MOSFET optically coupled to an infrared LED. It is packaged in S-VSON4T. The TLP3476S has a low CR product and very low on-state resistance, thus providing high on-current. In addition, the TLP3476S provides low insertion loss for high frequency signals, preventing degradation of fast rising signals. The Toshiba TLP3476S also features low off-state current and low output pin capacitance, making it suitable for high frequency measurement instrumentation applications.

 

TLP3476S is suitable for the pin electronics of semiconductor testers, which use a large number of relays that require a shorter switching time.
