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
