The Toshiba TLP172A is a photorelay in a 4-pin SOP package, combining an infrared emitting diode with a photo-MOSFET. This design provides a higher output current rating compared to phototransistor-type photocouplers, making it suitable for controlling high currents.
Key electrical specifications include a peak off-state voltage of 60 V (min), a trigger LED current of 3 mA (max), and an on-state current of 400 mA (max). The device also features a low on-state resistance of 2 Ω (max) and an isolation voltage of 1500 Vrms (min).
Packaged in a compact 4-pin SOP with a height of 2.1 mm and a pitch of 2.54 mm, the TLP172A is designed for surface mounting. It operates within a temperature range of -40°C to 85°C, with recommended operating conditions suggesting a supply voltage up to 48V and a forward current of 7.5mA.
This photorelay is well-suited for applications such as telecommunications control equipment, data acquisition systems, and security equipment where reliable On/Off control for higher currents is required.
