TLP172GM – Photorelay (MOSFET Output) – Toshiba
The Toshiba TLP172GM is a 1-Form-A (SPST-NO) MOSFET-output photorelay rated 350 V / 0.11 A with 3750 Vrms isolation in a compact 4-pin SO6 surface-mount package.
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.
