TLP383(D4BLLTR,E(T) – Optocoupler – Toshiba

The Toshiba TLP383(D4BLLTR,E(T) is a single-channel phototransistor-output photocoupler in a compact 4-pin SO6L surface-mount package, rated for 5000 Vrms isolation with a BLL current transfer ratio rank (200% to 400%). Available for RFQ at Pacific Component Xchange.

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.

Why Source TLP383(D4BLLTR,E(T) from Pacific Component Xchange

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.
