TLP172AM(TPL,E) – Photorelay – Toshiba

About this part

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.

Key Features

• MOSFET output photorelay with 1-Form-A (normally open) contact configuration
• Off-state output terminal voltage: 60 V (max)
• On-state current: 0.5 A (max)
• On-state resistance: 2 Ω (max) at I_F=5 mA, I_ON=0.5 A
• Trigger LED current: 3 mA (max)
• Isolation voltage: 3750 Vrms (min)
• Operating temperature range: -40 °C to +110 °C
• Compact 4-pin SO6 package (approx. 3.7 × 7.0 × 2.1 mm); halogen-free

Applications

• Factory automation (FA) and programmable logic controllers (PLCs)
• Mechanical relay replacement
• Measuring and test instruments
• Battery management systems (BMS, non-automotive)
• Security and alarm systems
