TLP3122 Description

Short technical summary and product information.

The Toshiba TLP3122 is a photorelay that utilizes a gallium arsenide infrared emitting diode optically coupled to a photo-MOS FET. Packaged in a 4-pin SOP, this bi-directional switch is suitable for replacing mechanical relays and controlling power lines.

 

Key electrical specifications include a 60V minimum peak off-state voltage, a maximum on-state current of 1A, and a typical on-state resistance of 0.25 Ohms. It also features a typical off-state capacitance of 90 pF and a maximum off-state current of 100 nA. The isolation voltage is rated at a minimum of 1500 Vrms.

 

Operating within a temperature range of -20°C to 85°C, the TLP3122 is designed for reliability in various industrial applications. Its SOP package has a pitch of 2.54 mm and a height of 2.1 mm, with a typical weight of 0.1 g.

 

This photorelay is well-suited for use in measurement instruments, logic testers, board testers, scanners, and factory automation systems where reliable switching is required.
