The Toshiba TLP240GA(D4TP1,F is a normally-open MOSFET-output photorelay that pairs an infrared LED with a photo-MOSFET output stage to deliver galvanically isolated load switching. With a minimum isolation voltage of 5000 Vrms, this single-pole solid state relay is well suited as a long-life, bounce-free replacement for mechanical relays. The “D4TP1,F” suffix denotes a specific Toshiba package/shipping-form variant of the base TLP240GA device.
Authorized-distributor stock for the TLP240GA(D4TP1,F can be limited, making this a hard-to-find part for production and maintenance buyers. Pacific Component Xchange specializes in sourcing scarce, allocated, and end-of-life isolation components, optocouplers, and photorelays. Our team verifies authenticity, supports global shipping, and can locate the exact packaging variant you need. Request a quote (RFQ) today and our sourcing specialists will respond with availability, lead time, and pricing for the quantity you require.
The orderable Toshiba part number is TLP240GA(D4TP1,F. The base device is the TLP240GA MOSFET-output photorelay; the trailing suffix designates a specific Toshiba package and tape-and-reel shipping-form variant. Any further trailing characters seen in some listings are packaging/origin fragments.
The TLP240GA is a single-channel (1-Form-A / SPST-NO) MOSFET-output photorelay, a solid state relay that uses an infrared LED to drive a photo-MOSFET output stage for galvanically isolated load switching.
The TLP240GA is rated for an off-state output terminal voltage of 400 V (min) and an on-state (load) current of 0.12 A (120 mA) max, with a maximum on-state resistance of 35 u03a9.
It provides a minimum isolation voltage of 5000 Vrms between the input LED and the output MOSFET.
Yes. According to Toshiba's product information the TLP240GA is an active part. However, authorized-distributor availability for the specific D4TP1 variant can be limited, which is why it is offered on an RFQ basis at Pacific Component Xchange.
Yes. As a MOSFET-output solid state relay it offers bounce-free, long-life switching with no moving parts, making it a common replacement for small mechanical relays in instrumentation, security, and industrial I/O applications.
