The Toshiba TLP3022 is a photocoupler consisting of a photo-triac optically coupled to a gallium-arsenide (GaAs) infrared emitting diode, housed in a 6-lead plastic DIP package. Designed as a non-zero-cross triac driver, it provides optical isolation between low-voltage control circuitry and AC mains-side loads, making it a proven building block for solid-state relays and AC switching interfaces. As an older Toshiba photocoupler, the TLP3022 is now difficult to source through authorized channels, and Pacific Component Xchange offers it as a Request-For-Quote (RFQ) line item for engineers maintaining legacy designs.
Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs and optocouplers. The TLP3022 has little to no authorized-distributor availability, so if your bill of materials still depends on this Toshiba photo-triac coupler, our sourcing team can help. We focus on authenticity and traceability, supporting end-of-life and legacy components that are no longer in mainstream production, with global shipping to keep your production lines and repairs moving.
Need TLP3022 in volume or for a one-time build? Submit a Request For Quote (RFQ) with your target quantity and date code requirements, and our team will respond with current availability and pricing for this obsolete part.
The TLP3022 is a Toshiba photocoupler with a photo-triac output, optically coupled to a GaAs infrared LED in a 6-lead plastic DIP package. It functions as a non-zero-cross triac driver for switching AC loads with electrical isolation.
The base orderable part is TLP3022. The trailing (S,F,T) characters are Toshiba packaging and lead-form suffix codes; the core device is the TLP3022 photo-triac optocoupler.
Confirmed datasheet ratings include a 400 V (Min.) peak off-state voltage, 10 mA (Max.) trigger LED current, 100 mA (Max.) on-state current, and 5000 Vrms (Min.) isolation voltage.
The TLP3022 is an older Toshiba photocoupler that is obsolete and no longer broadly available through authorized distribution. Pacific Component Xchange offers it as a Request-For-Quote item for legacy and repair builds.
The TLP3020 through TLP3023 share the same photo-triac architecture but differ in maximum trigger LED current. The TLP3022 is rated 10 mA (Max.), making it more sensitive than the 15 mA TLP3021 and less sensitive than the 5 mA TLP3023, which requires the lowest trigger current in the group.
Because the TLP3022 is an obsolete, hard-to-find part, it is offered on a Request-For-Quote basis. Submit an RFQ with your quantity and date-code needs, and our sourcing team will respond with availability and pricing.
