The Toshiba TLP268J is a zero-crossing phototriac output optocoupler that pairs a GaAs infrared LED with a zero-cross photo triac. Designed as a reliable triac driver, it provides reinforced galvanic isolation between low-voltage control logic and AC line-side power circuits, making it a workhorse coupler for AC switching and solid-state relay designs. The TLP268J is housed in the slim SO6 (4-pin) surface-mount package and guarantees a creepage and clearance distance of 5.0 mm (min) with an internal isolation thickness of 0.4 mm (min), allowing it to meet the reinforced insulation class requirements of international safety standards.
The Toshiba TLP268J is a specialty isolation device with limited authorized-distributor stock, which makes it a frequent target for procurement teams chasing line-down and end-of-allocation situations. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs, photocouplers, and photorelays. We help engineers and buyers secure the TLP268J when standard channels show no availability, including the full ordering variants such as TLP268J(TPL,E(T tape-and-reel packaging and the EN60747-5-5 Option (V4) type.
Every order is backed by our authenticity and counterfeit-avoidance process, with inspection and traceability so you receive genuine Toshiba parts. We support global shipping and fast quotes for both prototype and production volumes. Request a quote (RFQ) today for current pricing, lead time, date codes, and packaging options on the TLP268J, and let our sourcing team handle the hard-to-find search for you.
The TLP268J is a Toshiba photocoupler consisting of a GaAs infrared LED optically coupled to a zero-crossing photo triac. It functions as a triac driver, providing reinforced isolation between control logic and AC line-side circuits in a 4-pin SO6 surface-mount package.
Yes. The TLP268J includes zero-crossing (ZC) functionality for zero-voltage turn-on, which reduces switching noise and inrush current when driving AC loads and external triacs.
The base orderable part number is TLP268J. The suffix TLP268J(TPL,E(T denotes the shipment packaging: TPL is the tape type, E indicates RoHS compatibility, and (T indicates Thailand country of origin. An EN60747-5-5 (VDE) approved variant is ordered using the Option (V4) designation, e.g. TLP268J(V4-TPL,E(T.
It is rated for 600 V (min) peak off-state voltage (VDRM), 70 mA (max) RMS on-state current, a trigger LED current of 3 mA max (2 mA max for the IFT2 rank), and 3750 Vrms (min) isolation voltage.
The TLP268J provides a minimum isolation voltage of 3750 Vrms (AC, 1 minute), with 5.0 mm minimum creepage and clearance and 0.4 mm minimum internal isolation thickness, meeting reinforced insulation class requirements.
Yes. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs and optocouplers. We can locate the TLP268J, including tape-and-reel and Option (V4) variants. Submit an RFQ for current pricing, lead time, and availability.
