ISP847ASM

Transistor, Photovoltaic Output Optoisolators Overview

The ISP847ASM is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features four separate channels within a single DIP-16 plastic package, providing robust electrical isolation for multi-circuit applications. The device utilizes an infrared LED input paired with NPN phototransistor outputs to ensure reliable signal transmission across isolated boundaries. Key electrical specifications include a maximum insulation voltage of 5300 Vrms and a minimum collector-emitter breakdown voltage of 35 V. The unit supports a maximum forward current of 50 mA and operates within a temperature range of -55 °C to 100 °C. It carries UL recognition (File No. E91231) and VDE approval under standard 0884.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Four-channel configuration in a compact DIP-16 package for space-efficient circuit design
• High-voltage isolation capability up to 5300 Vrms for safe boundary crossing
• Compliance with international safety standards including UL and VDE certifications

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring multi-channel signal isolation

• Data acquisition modules with multiple isolated inputs

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'ASM' against official datasheets to confirm lead frame material and moisture sensitivity level. Ensure the ordering code matches the required packaging format, as variations exist between tube and reel options. Cross-reference the UL file number E91231 for regulatory compliance requirements in your target market.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when four independent isolated channels are required in a single footprint. The 5300 Vrms rating suits high-noise industrial environments. Verify that the 50 mA maximum forward current meets the drive requirements of the source circuit. Consider the operating temperature range if deployed in extreme thermal conditions.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP817/ISP827/ISP847 series of high-density phototransistor optocouplers. The '847' designation typically indicates a higher Current Transfer Ratio compared to standard 817 variants. The 'X' suffix often denotes specific lead form or certification variations, while 'ASM' specifies the surface mount or specific packaging variant within the DIP-16 family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements may include other quad-channel DIP-16 optocouplers such as the PC847 or ILQ847. Verify pinout compatibility and isolation voltage ratings before substitution. Ensure the replacement device meets the same UL and VDE safety approvals if used in certified equipment.
