The Toshiba TLP185(BLL-TPL,SE(T) is a single-channel transistor-output photocoupler that pairs a GaAs infrared emitting diode with a silicon phototransistor inside a very small, thin 4-pin SO6 surface-mount package. The “BLL” suffix designates a current transfer ratio (CTR) rank of 200% to 400%, while the “-TPL,SE(T” portion of the ordering code indicates the tape-and-reel packing and SE lead/marking option. This device is widely used to provide galvanic isolation between control logic and higher-voltage circuitry in space-constrained, high-density surface-mount designs.
The TLP185 family is marked Not Recommended for New Design (NRND) by Toshiba, and the BLL-rank, tape-and-reel variant can be difficult to obtain through authorized distribution. Pacific Component Xchange specializes in hard-to-find and end-of-life optocouplers and power-management components, helping engineers and buyers keep existing designs in production. We focus on authenticity, traceability, and reliable global shipping for obsolete and allocation-constrained components.
This is a Request-for-Quote item. Submit an RFQ to Pacific Component Xchange for current availability, lead time, date codes, and pricing on the Toshiba TLP185(BLL-TPL,SE(T) and equivalent CTR ranks.
The source code is a slightly garbled rendering of Toshiba's standard ordering format. The clean orderable part number is TLP185(BLL-TPL,SE(T), where BLL designates the 200-400% CTR rank and the -TPL,SE(T suffix denotes the tape-and-reel packing and SE option. The core device is the Toshiba TLP185 transistor-output photocoupler.
BLL is Toshiba's classification for a current transfer ratio (CTR) of 200% to 400%. CTR is the ratio of output collector current to input forward current, measured at IF=5mA and VCE=5V. Other ranks in the family include BL (200-600%), GB (100-600%), GR (100-300%) and Y (50-150%).
It uses Toshiba's very small, thin 4-pin SO6 surface-mount package (approximately 3.7 x 7.0 x 2.1 mm), which is well suited to high-density surface-mount assembly such as PLC I/O boards.
Toshiba lists the TLP185 family as Not Recommended for New Design (NRND). It remains usable for maintaining existing designs, but availability through authorized channels can be limited, which is why it is offered on an RFQ basis through Pacific Component Xchange.
The TLP185 provides an isolation voltage of 3750 Vrms for 1 minute and is certified to UL 1577, cUL (CSA) and EN 60747-5-5 (VDE) safety standards.
