The Toshiba TLP183(BL-TPL,E(T) is a low input-current phototransistor-output photocoupler that pairs an infrared emitting diode optically coupled to a silicon phototransistor inside a compact 4-lead SO6 surface-mount package. The “BL” suffix identifies the current-transfer-ratio (CTR) rank (200 to 600%), the “TPL” suffix indicates L-direction tape-and-reel packing, and the “E” suffix denotes RoHS-compatible, lead-free packaging. Smaller than a conventional DIP package, the TLP183 is well suited to high-density surface mounting in space-constrained isolation designs.
The TLP183(BL-TPL,E(T) is a rank-specific variant with limited authorized-distributor availability. As an independent distributor specializing in optocouplers and power-management components, Pacific Component Xchange helps engineers and buyers secure scarce and obsolete components without redesign delays. We focus on authenticity, traceability, and reliable global shipping for production and prototype quantities alike.
Because this part is offered on a Request-For-Quote basis, pricing and lead time are confirmed per order. Submit an RFQ to Pacific Component Xchange for current availability, quantity pricing, and date-code options on the Toshiba TLP183(BL-TPL,E(T).
The source string is a slightly garbled packing code. The base device is the Toshiba TLP183; the ordering code is TLP183(BL-TPL,E(T), where BL is the CTR rank, TPL indicates L-direction tape-and-reel packing, E denotes RoHS-compatible lead-free packaging, and the trailing (T relates to the reel/quantity packing.
The TLP183 is a single-channel phototransistor-output photocoupler (optocoupler). It transfers a signal across an isolation barrier using an infrared LED coupled to a phototransistor, providing 3750 Vrms galvanic isolation between input and output.
It uses a compact 4-lead SO6 surface-mount package (Toshiba 11-4M1S mini-flat outline), which is smaller than a traditional DIP and suited to high-density board layouts.
BL is a current-transfer-ratio (CTR) rank. For the BL rank the TLP183 has a CTR of 200 to 600% (measured at IF = 5 mA, VCE = 5 V), per the Toshiba datasheet. The full TLP183 family spans CTR ranks from 50% up to 600%.
The TLP183 provides a minimum isolation voltage of 3750 Vrms (AC, 60 seconds). It is recognized/approved under UL 1577, cUL (CSA), EN 60747-5-5 and EN 62368-1 (VDE), and CQC GB4943.1 / GB8898.
Yes. Per Toshiba, when a VDE-approved (EN 60747-5-5) type is needed you designate the Option (V4). The BL-TPL,E ordering code shown here is the standard rank/tape/RoHS code; confirm the exact suffix you require when submitting an RFQ.
It is offered on a Request-For-Quote basis with limited authorized-distributor stock. Pacific Component Xchange can source it; submit an RFQ for current availability, pricing, and lead time.
