PS2501-4 4-Channel Phototransistor Optocoupler IC – DIP-16

Description

The PS2501-4 is a high-performance, 4-channel optocoupler IC designed for space-efficient electrical isolation. Each channel consists of an infrared light-emitting diode (LED) optically coupled to an NPN silicon phototransistor. This multi-channel configuration allows for the simultaneous isolation of four independent signals in a single, compact Dual-In-Line (DIP-16) package.

Engineered for versatility and safety, the PS2501-4 provides a high Current Transfer Ratio (CTR) and a high collector-emitter breakdown voltage (BVCEO), making it an excellent choice for signal transmission between systems with varying potentials and impedances. It is widely used in industrial controllers and measuring instruments where reliable ground isolation is essential for system stability.
