The Toshiba TLP183(BL-TPR,E is a single-channel photocoupler that pairs an infrared GaAs LED with a silicon phototransistor for galvanic isolation of signals. The BL rank designates a current-transfer-ratio (CTR) bin of 200% to 600%, while the TPR,E suffix indicates the device is supplied in embossed carrier tape-and-reel for automated surface-mount assembly. As a member of Toshiba’s low-input-current TLP18x family, the TLP183 is well suited to applications that must operate from limited drive current while delivering reliable isolated signal transfer in a small footprint.
The TLP183(BL-TPR,E can be difficult to obtain through authorized channels in the quantities and lead times many buyers need. Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocated isolation and power-management components. We help engineers and procurement teams secure this Toshiba photocoupler for new builds, line-down situations, and end-of-life or obsolete sourcing needs. Every order is backed by authenticity verification and quality screening, with global shipping to keep your production on schedule.

It is a single-channel phototransistor-output photocoupler from Toshiba. It uses an infrared LED optically coupled to a silicon phototransistor to provide galvanic isolation of signals in a compact SO6 (4-pin) surface-mount package.
BL is the current-transfer-ratio (CTR) rank. Per the Toshiba datasheet, the BL-ranked TLP183 provides a CTR of 200% (min) to 600% (max), measured at both IF = 5 mA and IF = 0.5 mA with VCE = 5 V.
TPR,E denotes the packaging form: the device is supplied on embossed carrier tape and reel for automated surface-mount (SMT) pick-and-place assembly.
The TLP183 is rated for an isolation voltage of 3750 Vrms (minimum), making it suitable for primary-to-secondary isolation in power supplies and isolated interfaces.
It comes in Toshiba's SO6 four-pin surface-mount package, which is smaller than a traditional DIP and intended for high-density SMT mounting.
Yes. This is a hard-to-find part with limited authorized-distributor stock, and Pacific Component Xchange offers it on a request-for-quote (RFQ) basis. Contact us for current availability, lead time, and pricing.
