The Toshiba TLP387(D4-TPR,E is a high-isolation transistor-output photocoupler that pairs an infrared LED with a photo-Darlington output transistor in a compact 4-pin SO6L surface-mount package. With a guaranteed minimum current transfer ratio (CTR) of 1000% at just 1 mA of LED drive current, it is engineered for designs that must switch loads while drawing minimal input current, making it well suited to programmable controllers, I/O interface boards, and home electric appliances.
Its 5000 Vrms isolation rating and 300 V collector-emitter voltage support robust galvanic separation between low-voltage logic and higher-voltage I/O, including the 100 VDC output modules of programmable controllers, while the wide -55 to 110 degrees C operating temperature range covers demanding industrial environments.
The TLP387(D4-TPR,E can carry limited authorized-distributor stock, which makes it a frequent pain point for buyers managing active builds and EOL risk. Pacific Component Xchange is an independent distributor specializing in hard-to-find optocouplers and power-management components. We help engineering and procurement teams secure scarce, allocated, and obsolete components through a vetted global supply network.
Every TLP387(D4-TPR,E we source is subject to authenticity verification and quality inspection to guard against counterfeit risk, and we ship worldwide to meet your production timelines. Because this is a request-for-quote item, pricing and lead time are confirmed per request. Submit an RFQ to Pacific Component Xchange today for current availability, dating, and a competitive quote on the Toshiba TLP387(D4-TPR,E.
The garbled string TLP387(D4-TPR.E(T resolves to the orderable Toshiba part number TLP387(D4-TPR,E. The base device is the TLP387; the D4 VDE-approved option code, TPR tape-and-reel packaging, and E suffix define this specific orderable variant.
It is a single-channel transistor-output photocoupler (optocoupler) consisting of an infrared LED optically coupled to a Darlington output transistor, housed in a 4-pin SO6L surface-mount package.
The TLP387 provides 5000 Vrms isolation voltage (minimum, 1 minute) and a minimum collector-emitter voltage of 300 V, with a minimum current transfer ratio of 1000% at IF = 1 mA and VCE = 1 V.
Yes. Per Toshiba's product information the TLP387 is an active product with no end-of-life notice. Authorized-distributor stock can be limited, so it is offered on a request-for-quote basis through Pacific Component Xchange.
Per Toshiba's datasheet, typical applications include programmable logic controllers (PLCs), I/O interface boards, 100 VDC output modules of programmable controllers, and home electric appliances.
Because this is a hard-to-find, request-for-quote item, submit an RFQ to Pacific Component Xchange. We will confirm current availability, date codes, and a competitive quote from our verified global supply network.
