The Toshiba TLP225A is a 1-channel (1-Form-A) MOSFET-output photorelay that pairs a gallium-arsenide infrared LED with a photo-MOSFET output stage inside a compact 4-pin plastic DIP (DIP4) package. It delivers normally-open contact switching with no mechanical contacts, providing long operating life, silent operation, and bounce-free switching for low-current load control. The TLP225A is now an end-of-life / obsolete device, and Pacific Component Xchange sources it for engineers maintaining legacy designs and production lines.
The TLP225A has reached end-of-life status with little to no authorized-distributor stock remaining, making it a genuinely hard-to-find part. Pacific Component Xchange specializes in obsolete and end-of-life power-management ICs and optocouplers, helping OEMs and contract manufacturers keep legacy boards in production without costly redesigns. Every unit is inspected for authenticity and traceability, and we ship globally to support your maintenance, repair, and last-time-buy programs. Request a quote (RFQ) for the TLP225A today and our sourcing team will respond with current availability, lead time, and pricing.
The TLP225A is a single-channel MOSFET-output photorelay (solid state relay) from Toshiba. It couples a gallium-arsenide infrared LED to a photo-MOSFET output in a 4-pin plastic DIP (DIP4) package, providing isolated, bounce-free switching of low-current loads.
The TLP225A is rated for a 60 V peak off-state voltage, 0.5 A maximum on-state current, 1.1 u03a9 maximum on-state resistance, a 5 mA maximum trigger LED current, and 2500 Vrms minimum isolation voltage.
It uses Toshiba's DIP4 package, a 4-pin through-hole plastic DIP with approximate dimensions of 4.58 x 7.62 x 3.65 mm.
No. The TLP225A has been declared end-of-life (obsolete) by Toshiba. Toshiba lists the TLP240A as a recommended replacement with nearly identical package and characteristics. Pacific Component Xchange can source the original TLP225A for legacy and maintenance needs.
Toshiba recommends the TLP240A as a successor, noting that its package and characteristics are almost the same as the TLP225A. Always verify against your design before substituting.
Because the TLP225A is end-of-life with little authorized-distributor stock, it is offered as a request-for-quote (RFQ) item. Submit an RFQ to Pacific Component Xchange and our team will provide current availability, lead time, and pricing.
