TLP240JF – Photorelay – Toshiba

About this part

The Toshiba TLP240JF is a MOSFET-output photorelay (solid state relay) that pairs an infrared LED with a photo-MOSFET output stage to deliver clean, bounce-free, galvanically isolated switching. Configured as a single normally open (1-Form-A) contact, it is a drop-in solid state alternative to small electromechanical relays in instrumentation and industrial control designs. The TLP240JF is the wide-creepage “F type” variant of the TLP240J family, housed in a 4-pin DIP package with a 10.16-mm lead pitch for applications that demand reinforced insulation.

Key Features

• Normally open contact configuration (1-Form-A)

• Package: DIP4 (F type, 10.16-mm pitch) for wider creepage and clearance (8.0 mm min)

Applications

• Mechanical relay replacement
• Measuring and test instrumentation
• Security systems
• Factory automation (FA) and industrial control
• Smart meters and electricity meters
• Amusement equipment
