The Toshiba TLP118 is a high-speed, single-channel logic-output photocoupler (optocoupler) that pairs a GaAs infrared LED with a high-sensitivity photo-IC detector. Rated for data rates up to 20 Mbps and a 3750 Vrms (min) isolation voltage, the TLP118 delivers galvanic isolation for digital signal paths while maintaining fast, clean switching over an operating temperature range of -40 C to 125 C. It is supplied in a space-saving 5-lead SO6 gull-wing surface-mount package.
The TLP118 is marked Not Recommended for New Design (NRND) by Toshiba, which lists the TLP2368 as a replacement with nearly identical package and characteristics. With limited authorized-distributor availability, the TLP118 is a hard-to-find part for repair, maintenance, and legacy production runs. Pacific Component Xchange specializes in sourcing obsolete and allocation-constrained optocouplers and isolation ICs. We support legacy and end-of-life designs with authenticity-verified inventory, careful component handling, and global shipping. If your build still depends on the TLP118, request a quote and our team will source genuine parts to keep your line running. Submit an RFQ today for current availability, lead time, and pricing.
The TLP118 is a single-channel high-speed logic-output photocoupler (optocoupler) from Toshiba. It combines a GaAs infrared LED with a photo-IC detector to provide galvanic isolation for digital signals at data rates up to 20 Mbps, in a 5-lead SO6 surface-mount package.
The TLP118 provides an isolation voltage of 3750 Vrms (minimum) and is UL 1577 recognized.
The TLP118 has an inverter-logic, open-collector output and operates from a 4.5 V to 5.5 V supply (Vcc). It offers a guaranteed common-mode transient immunity of +/-15 kV/us.
The TLP118 is marked Not Recommended for New Design (NRND) by Toshiba and is treated as obsolete by some distributors. Toshiba lists the TLP2368 as having similar package and characteristics for new designs. For existing designs, Pacific Component Xchange can source the TLP118 on an RFQ basis.
The TLP118 is supplied in a compact 5-lead SO6 gull-wing surface-mount (SMD) package.
The TLP118 supports data rates up to 20 Mbps with a maximum propagation delay of 60 ns (tpHL / tpLH), making it suitable for high-speed isolated digital interfaces.
Because the TLP118 is an NRND part with limited authorized-distributor stock, it is sold on a Request-for-Quote basis. Submit an RFQ to Pacific Component Xchange and our team will provide current availability, lead time, and pricing for genuine parts.
