Surface mount photo relay is for factory automation

For factory automation and other industrial applications, including building automation, security and semiconductor testing, Toshiba Electronics Europe has released the TLP3122A photo relay.

The TLP3122A photo relay integrates MOSFET devices fabricated using the latest U-MOS IX process to reduce on-state resistance, says Toshiba Electronics Europe. Housed in the small four-pin SO6 package, the TLP3122A provides an off-state output terminal voltage (VOFF) of 60V, a constant on-state current (ION) of 1.4A and an on-state pulsed current (IONP) up to 4.2A. The on-state resistance (RON) is typically just 0.13-Ohm, allowing highly efficient operation while the off-state current is only one microA.

The TLP3122A offers fast switching times of three milliseconds (tON) and one milliseconds (tOFF) with an isolation voltage of 3750V rms. It is approved to UL1577 for safety-critical applications.

The normally-open TLP3122A serves as a replacement for 1-Form-A mechanical relays to improve system reliability and save the space required for relays and relay drivers. It is also rated for an operating temperature between -40 and +110 degree C, making it suitable for industrial applications, says Toshiba, and which makes it easier to allow for a temperature margin in system-level thermal design.

The TLP3122A photo relay is upwardly compatible with the TLP3122 in the conventional 2.54SOP package. It also helps increase the system drive current, making it possible to serve as a replacement for a wider range of mechanical relays, says the company.

Volume shipment of the TLP3122A has begun.

Toshiba Electronics Europe (TEE) is the European electronic components business of Toshiba Electronic Devices and Storage Corporation. TEE offers a broad IC and discrete product line including high-end memory, microcontrollers, ASICs and ASSPs for automotive, multimedia, industrial, telecomms and networking applications. The company also has a wide range of power semiconductor solutions as well as storage products including HDDs, SSDs, SD Cards and USB sticks.

TEE was formed in 1973 in Neuss, Germany, and provides design, manufacturing, marketing and sales services. Today, it has headquarters in Düsseldorf, Germany, with branch offices in France, Italy, Spain, Sweden and the United Kingdom. TEE employs approximately 300 people in Europe.
