PS2703-1 Description

Short technical summary and product information.

The NEC PS2703-1 is an optically coupled isolator designed for interface circuits in various instrumentation and control equipment. It utilizes a GaAs light-emitting diode and an NPN silicon phototransistor, housed in a compact SOP (Small Outline Package) suitable for high-density applications.

Key electrical characteristics include a high isolation voltage of 3750 Vr.m.s. (minimum) and a high collector-to-emitter voltage (VCEO) of 120V (minimum). The device offers fast switching speeds with typical rise and fall times of 10µs. It also features a low collector dark current of 5nA typical at 25°C.

This optocoupler is designed for applications such as AC line/digital logic interfaces, twisted pair line receivers, and high-frequency power supply feedback control. The SOP package facilitates surface mounting for efficient board layout.

Absolute maximum ratings include a forward current of 50mA, a reverse voltage of 6V, and power dissipation of 80mW for the diode and 150mW for the transistor per channel. Storage temperature ranges from -55°C to +150°C, and operating ambient temperature is -55°C to +100°C.
