The Toshiba TLP293(GR-TPL,E) is a single-channel optocoupler (photocoupler) that pairs an infrared LED with a silicon phototransistor inside a low-profile SO4 surface-mount package. Designed for high-density mounting, it delivers a guaranteed 3750 Vrms isolation voltage and a wide -55°C to +125°C operating temperature range, making it a dependable galvanic-isolation building block for industrial and power-supply designs. The “GR” suffix designates the current transfer ratio (CTR) rank, and “TPL,E” indicates tape packaging in the L direction with RoHS-compatible (lead-free) terminations.
Pacific Component Xchange is an independent distributor specializing in hard-to-find and allocated power-management ICs and optocouplers. The TLP293(GR-TPL,E) is offered on a request-for-quote basis because authorized-distributor stock for this specific GR-rank, tape-and-reel variant can be limited or subject to lead time through standard channels. Our sourcing team locates scarce, obsolete, and long-lead Toshiba photocouplers, verifies authenticity, and ships globally to keep your production lines running. Submit an RFQ today for current pricing, lead time, and available quantity on the TLP293(GR-TPL,E), and our specialists will respond with a competitive, authenticity-backed quote.
The ordering code TLP293(GR-TPL,E) is Toshiba's TLP293 phototransistor optocoupler supplied in tape form. 'GR' is the current transfer ratio (CTR) rank, 'TPL' is the tape type (L direction), and 'E' denotes RoHS-compatible/lead-free terminations.
GR is Toshiba's CTR (current transfer ratio) classification. For the TLP293, the GR rank specifies a CTR of 100% to 300% measured at IF = 5 mA, VCE = 5 V, per Table 8.1 of the datasheet.
The TLP293 is guaranteed a minimum isolation voltage of 3750 Vrms, and it is UL 1577 / cUL recognized (File No. E67349) with VDE (Option V4) and CQC approvals available.
It is supplied in Toshiba's SO4, a compact 4-pin surface-mount package (pin 1 Anode, 2 Cathode, 3 Emitter, 4 Collector) suited to high-density board assembly.
This GR-rank tape variant is offered by Pacific Component Xchange on a request-for-quote basis. Submit an RFQ for current price, lead time, and quantity.
Toshiba lists switching power supplies, programmable logic controllers (PLCs), and I/O interface boards as primary applications, along with general signal and feedback isolation in industrial systems.
