The Toshiba TLP240J is a MOSFET output photorelay (solid state relay) that pairs an infrared LED with a photo-MOSFET output stage to deliver galvanically isolated, contactless switching. Configured as a single 1-Form-A (SPST normally open) channel rated for 600 V off-state voltage and 90 mA on-state current, the TLP240J is a long-life, bounce-free replacement for small electromechanical and reed relays in industrial and instrumentation designs. It is housed in a compact 4-pin DIP package and carries UL 1577, UL 508, cUL, VDE (EN 60747-5-5 / EN 62368-1) and CQC (GB 4943.1) safety recognition.
The Toshiba TLP240J is an active production part, but authorized-distributor inventory is frequently constrained, making it difficult to secure in the quantities and lead times that production schedules demand. Pacific Component Xchange is an independent distributor specializing in hard-to-find power-management ICs and optocouplers, and we help engineers and buyers locate genuine TLP240J photorelays when mainstream channels are out of stock. Every device is sourced for authenticity and supported by our quality and counterfeit-avoidance processes, with global shipping to your facility. Request a quote (RFQ) for the TLP240J today and our sourcing team will respond with availability, pricing and lead time for both prototype and production volumes.
The TLP240J is a Toshiba MOSFET output photorelay (solid state relay) in a 4-pin DIP package. It optically couples an infrared LED to a photo-MOSFET output stage to provide isolated, contactless switching as a 1-Form-A (normally open) channel.
The TLP240J is rated for an off-state output terminal voltage of 600 V (min) and an on-state current of 90 mA (0.09 A) max, with an on-state resistance of 40 ohm max (t < 1 s) or 60 ohm max continuous.
The TLP240J provides a minimum isolation voltage of 5000 Vrms and is recognized under UL 1577, UL 508, cUL, EN 60747-5-5 / EN 62368-1 (VDE) and GB 4943.1 (CQC) safety standards.
It is supplied in a compact 4-pin DIP (DIP-4) through-hole package, approximately 4.58 x 7.62 x 3.65 mm. The TLP240JF is a related variant with a 10.16 mm lead pitch.
Yes, the TLP240J is an active, halogen-free Toshiba production device (commercial production since 2013). However, authorized-distributor stock can be limited, so it is commonly sourced through independent distributors on an RFQ basis.
Submit a Request for Quote (RFQ) to Pacific Component Xchange. Because this is a hard-to-find part with limited authorized availability, our team provides current pricing, lead time and verified-authentic stock for both prototype and production quantities.
