A small photorelay for factory automation and industrial applications supporting up to 1.4 A: TLP3122A

Product News 2018-05

The package photograph of a small photorelay for factory automation and industrial applications supporting up to 1.4 A: TLP3122A.

"TLP3122A" is a photorelay with an OFF-state output terminal voltage rating of 60 V and an ON-state current rating of 1.4 A, using the 4pin SO6 package suitable for factory automation and other industrial applications.
The new product TLP3122A has reduced its ON-state resistance by incorporating a MOSFET fabricated with the latest generation process U-MOSIX having a trench structure in its detector and supports an ON-state current rating of up to 1.4 A and 4.2 A (pulsed) in the small 4pin SO6 package.
This product can replace a 1-Form-A mechanical relay. Replacing mechanical relays with photorelays helps improve system reliability and reduce the space required for relays and relay drivers. In addition, as the productʼs rated operating temperature is maximum 110 °C, it is easier to secure a temperature margin in system-level thermal design.
TLP3122A photorelay is upward compatible with the TLP3122 in the conventional 2.54SOP4 package.
It also helps increase the system drive current, and that makes possible to serve as a replacement for a wider range of mechanical relays.

Features

  • OFF-state output terminal voltage rating 60 V, ON-state current rating 1.4 A,
    ON-state current (pulsed) rating 4.2 A
  • Low ON-state resistance: RON=0.25 Ω (max)
  • High operating temperature rating: Topr (max)=110 °C

Applications

  • Industrial equipment (PLC, I/O interface)
  • Building automation systems (HVAC[1], etc.)
  • Semiconductor testers
  • Security equipment
  • Replacement of mechanical relays (AC 24 to 32 V system, DC 24 to 48 V system)
