The Toshiba TLP385(GB,E(T) is a high-isolation, transistor-output photocoupler (optocoupler) consisting of a gallium-arsenide infrared emitting diode optically coupled to a silicon phototransistor. It is supplied in Toshiba’s compact, low-profile 4-pin SO6L surface-mount package, which offers a meaningfully smaller and thinner footprint than a conventional DIP optocoupler while preserving robust input-to-output isolation. The “GB” designation specifies the current-transfer-ratio (CTR) rank, the “E” suffix denotes RoHS-compatible (lead-free) construction, and the “(T)” indicates tape-and-reel packaging for automated assembly.
The TLP385(GB,E(T) is a specific CTR-rank, tape-and-reel optocoupler variant that frequently shows little or no authorized-distributor stock, making it a challenge for buyers managing active production lines or legacy designs. Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocation-constrained power-management ICs and optocouplers. We help engineering and procurement teams locate scarce, end-of-allocation, and obsolete components through our global supply network, with attention to authenticity and traceability. Whether you need a single reel or volume quantities, our team can source the TLP385(GB,E(T) and arrange worldwide shipping. Request a quote (RFQ) today and our sourcing specialists will respond with current availability and pricing.
The garbled source string resolves to the Toshiba orderable part number TLP385(GB,E(T), also commonly written TLP385-GB-E-T. 'GB' is the current-transfer-ratio (CTR) rank, 'E' indicates RoHS-compatible lead-free construction, and '(T)' denotes tape-and-reel packaging.
The 'GB' suffix is Toshiba's CTR (current transfer ratio) rank classification. For the GB rank, CTR is guaranteed at 100% minimum (up to 600% max), measured at IF = 5 mA and VCE = 5 V.
The TLP385 is a high-isolation photocoupler with a guaranteed isolation voltage (BVS) of 5000 Vrms minimum, with minimum creepage and clearance distances of 8.0 mm.
It is supplied in Toshiba's low-profile 4-pin SO6L surface-mount package, which is smaller and thinner than a standard DIP optocoupler, making it well suited to high-density SMT assembly.
The TLP385 family is an active Toshiba product. However, this specific CTR-rank, tape-and-reel variant often has limited authorized-distributor stock. Pacific Component Xchange can source it on a request-for-quote (RFQ) basis.
The TLP385 is widely used in programmable logic controllers (PLCs), AC/DC adapters, switching power supplies, and I/O interface boards where reliable signal isolation in a compact surface-mount package is required.
Because this is a hard-to-find, RFQ-only part, submit a quote request to Pacific Component Xchange. Our sourcing team will check global availability, confirm authenticity, and provide current pricing and lead time with worldwide shipping options.
