Toshiba Launches High Current Photorelays with Reinforced Insulation

October 7, 2013 - Tokyo, Japan

Toshiba Corporation (TOKYO:6502) today announced that it has launched high current photorelays, “TLP241A” and “TLP241AF”, as new additions to its “TLP240” series in DIP4 packages offering reinforced insulation. Mass production is scheduled to start in November this year.
The products increase guaranteed maximum on-state current to 2A, four times that of the existing product1, allowing use in applications that include factory automation, which requires control of high current.

The “TLP240” series adopts a double-mold DIP4 package, realizing an isolation voltage of 5000Vrms (AC, 1 minute). The latest addition to the series will offer a wide range of off-state output terminal voltage, from 40 to 600V, allowing selection to meet system requirements for applications that include factory automation, smart meters and security equipment.

Key Features of New Products

  1. On-state current: ION = 2A (maximum)
  2. Off-state output terminal voltage: VOFF = 40V (minimum)
  3. Isolation voltage: BVS = 5000Vrms (minimum)
  4. Line-up of two products with different clearances and creepage distances
    TLP241A: 7mm (minimum)
    TLP241AF: 8mm (minimum)
  5. Package: DIP4 package

Factory automation control systems, smart meters, security equipment, measurement control systems, replacement of mechanical relays, and medical equipment.

1: Comparison with “TLP240A” and “TLP240AF” with a guaranteed maximum current of 500mA.
