The TLP9121A is a photocoupler (optocoupler) manufactured by Toshiba Electronic Devices & Storage Corporation. It belongs to Toshiba’s Photocouplers for IPM (Intelligent Power Module) Interface family, a line of optically isolated devices designed to provide a safe, noise-immune signal interface between low-voltage control logic and intelligent power modules in inverter, servo, and motor-drive applications.
According to distributor records, the TLP9121A is obsolete and no longer manufactured, which makes it a hard-to-find part with little or no authorized-distributor stock. Pacific Component Xchange offers it on a Request-For-Quote basis.
Note: The bullet points above reflect Toshiba’s IPM-interface photocoupler family documentation, not values confirmed from a part-specific TLP9121A datasheet. Confirm exact electrical ratings (supply voltage, output type, isolation voltage, propagation delay, CMR) and the exact package code for the TLP9121A ordering code against the official Toshiba datasheet before designing in.
The TLP9121A is an obsolete, specialized Toshiba photocoupler with limited or no authorized-distributor availability. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs and optocouplers. We source scarce and end-of-life Toshiba parts through a vetted global supply network, with authenticity verification and worldwide shipping. If you need TLP9121A for production, maintenance, or last-time buys, submit an RFQ to Pacific Component Xchange and our team will respond with current availability, lead time, and pricing.
The TLP9121A is a Toshiba photocoupler (optocoupler) from the company's Photocouplers for IPM (Intelligent Power Module) Interface family. It provides optically isolated signal transfer between control logic and an intelligent power module in inverter and motor-drive systems.
The TLP9121A is manufactured by Toshiba Electronic Devices & Storage Corporation (Toshiba).
Yes. Trailing characters such as '(NCNGBTL,F)' are Toshiba packing/taping suffixes appended to the base ordering code. The clean orderable part is TLP9121A; distributors such as DigiKey list it under the full ordering code TLP9121A(NCNGBTL,F).
No. Distributor records (DigiKey) list the TLP9121A as obsolete and no longer manufactured. Because it is end-of-life, it is best sourced on a Request-For-Quote basis.
Toshiba's IPM-interface photocoupler family supports 5 V and 15 V supply rails and offers open-collector and totem-pole (inverter- or buffer-logic) output stages. These are family-level characteristics; the exact supply rail, output type, and package for the TLP9121A should be confirmed against the official Toshiba datasheet.
Yes. Pacific Component Xchange specializes in hard-to-find and obsolete optocouplers and power-management ICs, with authenticity verification and global shipping. Contact us with your quantity and required date for a quote on this obsolete part.
