The TLP293(BL-TPL,E from Toshiba is a single-channel transistor-output photocoupler consisting of an infrared LED (IRED) optically coupled to a silicon phototransistor in a compact 4-pin SO4 surface-mount package. The “BL” designation specifies the current transfer ratio (CTR) rank, while the “-TPL,E” suffix indicates tape-and-reel packaging in a lead-free, RoHS-compliant finish. With a guaranteed minimum isolation voltage of 3750 Vrms and a wide operating temperature range of -55 to 125 degrees C, the TLP293 is built for high-density surface-mount designs that demand reliable galvanic isolation.
The TLP293(BL-TPL,E can be difficult to obtain in specific CTR ranks through authorized channels, with limited or no stock at franchised distributors. Pacific Component Xchange is an independent distributor specializing in hard-to-find and end-of-allocation power-management ICs and optocouplers. We help engineers and buyers secure rank-specific Toshiba photocouplers when standard supply lines are constrained, including obsolete and shortage-affected parts. Every order is backed by our authenticity and inspection processes, and we ship worldwide. Submit an RFQ today for current pricing, lead time, and available quantity on the TLP293(BL-TPL,E.
The Toshiba orderable code is TLP293(BL-TPL,E. Here, BL is the current transfer ratio (CTR) rank, TPL indicates tape-and-reel packaging, and E denotes the lead-free, RoHS-compliant version.
BL is one of Toshiba's CTR (current transfer ratio) rank suffixes used to bin photocouplers by gain. The TLP293 family is specified with a maximum CTR of 600%. The published TLP293 datasheet defines the blank rank (50% min) and the GB rank (100% min) at IF = 0.5 mA, VCE = 5 V; for the exact guaranteed CTR window of the BL rank, confirm against the current Toshiba ranking documentation or request it with your RFQ.
The TLP293 is guaranteed a minimum isolation voltage of 3750 Vrms (AC, 60 seconds), making it suitable for applications requiring robust galvanic isolation.
It is supplied in a low-profile 4-pin SO4 (4-SOIC) surface-mount package with 5.0 mm minimum creepage and clearance distances, designed for high-density surface mounting.
Yes. The E suffix indicates a lead-free, RoHS-compliant finish. The device is UL/cUL recognized (UL 1577, File No. E67349), VDE-approved (EN 60747-5-5, EN 62368-1 with the V4 option), and CQC-approved.
