PS2501-1L

Overview

The PS2501-1L is a single-channel optocoupler from the PS2501 series manufactured by Isocom Components. It features an infrared LED input and an NPN phototransistor output, housed in an 8-pin DIP package for through-hole mounting. The device provides high isolation voltage of 5300Vrms between input and output circuits. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4μs, and a typical fall time of 3μs. It operates within a temperature range of -30°C to 100°C and carries UL certification.

Feature Summary

• Provides galvanic isolation via infrared LED and NPN phototransistor interface
• Supports AC input signal processing capabilities
• Offers high dielectric strength with 5300Vrms isolation rating

Applications

• Logic-to-logic isolation in noisy environments
• Line receiver circuits
