The Toshiba TLP383(D4BLLTR,E(T) is a single-channel optocoupler that couples an infrared emitting diode (LED) to a silicon phototransistor across a high-isolation barrier. Built in Toshiba’s thin 4-pin SO6L surface-mount package, it delivers a guaranteed isolation voltage of 5000 Vrms together with a wide operating temperature range, making it well suited to dense, high-reliability board designs. This ordering code carries the D4 VDE-approved option designation, the BLL current transfer ratio rank (200% to 400%), and tape-and-reel packing.
Toshiba’s TLP383 family ships in volume reels, and specific CTR/packing ranks like the BLL tape-and-reel variant are frequently constrained or unavailable through authorized channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find power-management ICs and optocouplers. We help engineers and buyers secure scarce, allocated, and obsolete Toshiba photocouplers without redesigning around substitute ranks.
Every order is backed by our authenticity and counterfeit-avoidance process, with inspection and traceability on request, plus global shipping to production sites worldwide. Whether you need a single reel to clear a line-down or recurring supply of the TLP383(D4BLLTR,E(T), our team sources to your exact CTR rank and packaging. Request a quote (RFQ) today and our sourcing specialists will respond with availability, lead time, and pricing.
The intended Toshiba ordering code is TLP383(D4BLLTR,E(T) - the base device is TLP383, with D4 indicating the VDE-approved option, BLL the CTR rank (200% to 400%), and the suffix indicating tape-and-reel packing.
The TLP383 is rated for a minimum isolation voltage of 5000 Vrms (BVS, AC 60 s), making it suitable for high-isolation applications such as PLCs, I/O interface boards, and isolated power supplies.
BLL is the current transfer ratio (CTR) rank for this ordering code, corresponding to a CTR of 200% to 400%. Toshiba bins the TLP383 into several CTR ranks; BLL is the rank supplied with this specific part number.
It is supplied in Toshiba's thin 4-pin SO6L surface-mount package, which is smaller and lower-profile than a conventional DIP package for high-density mounting.
The TLP383 is UL 1577 recognized and cUL (CSA) recognized. The D4 option designates a VDE-approved type compliant with EN 60747-5-5 and EN 62368-1; it is also CQC approved.
Yes. Pacific Component Xchange is an independent distributor that sources hard-to-find and allocated Toshiba optocouplers. Submit an RFQ and our team will provide current availability, lead time, and pricing for your required CTR rank and packaging.
The TLP383 operates over a wide range of -55 C to +125 C, supporting industrial and harsh-environment designs.
