The Toshiba TLP172GM is a normally-open (1-Form-A, SPST-NO) photorelay that pairs an infrared GaAs LED with an optically coupled photo-MOSFET output stage. It delivers galvanic isolation between control and load circuits while switching loads up to 350 V at 0.11 A, making it an effective solid-state replacement for small mechanical relays in space-constrained designs. The device is housed in a low-profile 4-pin SO6 surface-mount package measuring just 3.7 x 7.0 x 2.1 mm.
The TLP172GM is a hard-to-find Toshiba photorelay with limited authorized-distributor stock. Pacific Component Xchange specializes in sourcing scarce and end-of-supply power-management ICs, optocouplers, and photorelays for engineers and procurement teams who cannot wait on extended factory lead times. Every TLP172GM we supply is verified for authenticity through our inspection and traceability process, and we ship worldwide to keep your production lines and prototype builds moving.
Need TLP172GM in volume or against a tight schedule? Request a quote (RFQ) from Pacific Component Xchange today and our sourcing specialists will respond with current availability, pricing, and lead time for this and related Toshiba photorelays.
The TLP172GM is a Toshiba 1-Form-A (SPST-NO) MOSFET-output photorelay. It optically couples an infrared LED to a photo-MOSFET to switch loads up to 350 V at 0.11 A while providing 3750 Vrms isolation, in a 4-pin SO6 surface-mount package.
The base orderable part number is TLP172GM. The trailing '(TPL,E(O' is a Toshiba packing/embossed-tape suffix indicating tape-and-reel and other packing options; it is not a different device. Toshiba also lists tape variants such as TLP172GM(TPR,E.
Off-state output voltage 350 V (min), on-state current 0.11 A, on-state resistance 50 u03a9 max (continuous), trigger LED current 3 mA max, isolation voltage 3750 Vrms (min), and an operating temperature range of -40 u00b0C to +110 u00b0C.
It comes in a low-profile 4-pin SO6 surface-mount package measuring 3.7 x 7.0 x 2.1 mm, with a height of about 2.1 mm.
