Toshiba Releases Small Photorelays With High Speed Turn-On Time That Help Shorten Test Time For Semiconductor Testers

KAWASAKI, Japan, Feb 20 (Bernama) -- Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched "TLP3414S” and “TLP3431S," photorelays housed in the S-VSON4T[1] package that feature a faster turn-on time than Toshiba’s current products[2]. The OFF-state output terminal voltage rating and the ON-state current rating of TLP3414S are 40V/250mA and those of TLP3431S are 20V/450mA. Shipments start today.

The new photorelays achieve high efficiency optical coupling with improved optical output from the input side infrared-emitting diodes and optimization of photo detectors (photodiode arrays). This realizes a high speed turn-on time, a maximum of 150μs. The turn-on time of TLP3414S is approximately 50% shorter than that of Toshiba’s current product, TLP3414, and that of the TLP3431S is approximately 62% shorter than Toshiba’s current TLP3431.
