What is the orderable part number for TLP240GA(D4TP1,F?

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.

What type of device is the TLP240GA?

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.

What are the maximum load ratings of the TLP240GA?

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.

What isolation voltage does the TLP240GA provide?

It provides a minimum isolation voltage of 5000 Vrms between the input LED and the output MOSFET.

Is the TLP240GA still in production?

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.

Can the TLP240GA replace a mechanical relay?

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.
