The Toshiba TLP172A consists of a gallium arsenide infrared emitting

diode optically coupled to a photo-MOSFET in a 4-pin SOP package. This

photorelay has higher output current rating than phototransistor-type

photocoupler; hence, it is suitable for use as On/Off control for high

current.

• 4-pin SOP (2.54SOP4): Height = 2.1 mm, pitch = 2.54 mm

• Normally open (1-form-A) device

• Peak off-state voltage: 60 V (min)

• Trigger LED current: 3 mA (max)

• On-state current: 400 mA (max)

• On-state resistance: 2 Ω (max)

• Isolation voltage: 1500 Vrms (min)

• UL recognized: UL1557, File No.E67349
