What is the correct orderable part number for this Toshiba photorelay?

The orderable Toshiba code is TLP172AM(TPL,E), where the (TPL,E) suffix indicates the tape-and-reel, halogen-free packaging variant of the TLP172AM photorelay.

What type of component is the TLP172AM?

It is a MOSFET-output photorelay (solid-state relay / photocoupler) with a 1-Form-A normally open contact configuration, housed in a 4-pin SO6 package.

What are the voltage and current ratings of the TLP172AM?

The TLP172AM is rated for an off-state output voltage of 60 V (max) and an on-state current of 0.5 A (max), with an on-state resistance of 2 u03a9 (max) and an isolation voltage of 3750 Vrms (min).

What can the TLP172AM be used for?

Typical uses include factory automation and PLCs, mechanical relay replacement, measuring instruments, battery management systems (non-automotive), and security systems.

Is the TLP172AM still in production?

Yes, the TLP172AM is in active full production. Toshiba lists the TLP176AM as a newer alternative for new designs, but the TLP172AM remains available.

Can Pacific Component Xchange supply the TLP172AM if distributors are out of stock?

Yes. Pacific Component Xchange specializes in hard-to-find and allocated optocouplers and photorelays. Submit an RFQ and we will provide current availability, lead time, and pricing.

The Toshiba TLP172AM is a 1-Form-A (normally open) photorelay that pairs an infrared LED with a photo-MOSFET output stage to deliver clean, bounce-free, solid-state switching. Supplied in a low-profile 4-pin SO6 package, it is a solid-state alternative to electromechanical relays in applications demanding long service life, silent operation, and high reliability. The ordering code TLP172AM(TPL,E) denotes the tape-and-reel, halogen-free packaging option.
