PS2501-1GRSMT&R

Overview

The PS2501-1GRSMT&R is a single-channel optically coupled isolator manufactured by Isocom Components. It integrates an infrared light-emitting diode with an NPN silicon phototransistor in a surface-mount package. The device provides high isolation voltage of 5300Vrms and supports a minimum current transfer ratio of 80%. It features a typical rise time of 4μs and fall time of 3μs, with a maximum forward voltage of 1.4V and maximum input current of 50mA. The unit operates within a temperature range of -30°C to 100°C and includes UL recognition.

Feature Summary

• Integrates infrared LED and NPN silicon phototransistor for optical signal transmission
• Provides high electrical isolation between input and output circuits
• Ensures reliable performance through 100% electrical parameter testing

Applications

• Computer terminals
• Industrial systems controllers
• Measuring instruments
• Signal transmission between systems of different potentials and impedances

Procurement Notes

Verify the specific suffix 'GRSMT&R' against official manufacturer documentation to confirm lead spread dimensions, tape-and-reel packaging specifications, and exact electrical tolerances. Ensure compliance with required safety certifications such as UL recognition before integration into final designs.

Selection Notes

Select this component when space-efficient surface-mount technology is required alongside high-density mounting capabilities. Consider its high current transfer ratio and fast switching characteristics for applications demanding efficient signal isolation between disparate system potentials.

Part Context

This part belongs to the PS2501 series of high-density mounting phototransistor optically coupled isolators. The series combines infrared LEDs with NPN silicon phototransistors in dual-in-line plastic packages, offering versatile configuration options including standard leads, surface mount variants, and custom electrical selections.

Replacement Considerations

Compatible substitutes include PS2501-1, PS2501-2, and PS2501-4 from Isocom Components. Cross-manufacturer equivalents may be considered if they match the 5300Vrms isolation rating and transistor output type.
