ISP847SMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ISP847SMT&R is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. This device features four independent channels within a single DIP-16 plastic package, providing robust electrical isolation with a maximum insulation voltage of 5300 Vrms. It utilizes NPN phototransistor outputs and supports a maximum forward input current of 50 mA. The component operates across an extended temperature range from -55 °C to 100 °C. Key electrical characteristics include a minimum collector-emitter breakdown voltage of 35 V and a maximum dark power of 100 nA. The unit is compliant with RoHS standards and holds UL recognition (File No. E91231) and VDE approval.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Four-channel configuration for multi-signal isolation in compact space
• High insulation voltage rating of 5300 Vrms for safety-critical applications
• Surface-mountable DIP-16 package design for automated assembly
• Certified compliance with UL and VDE safety standards

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring multi-channel signal isolation
• Power supply units needing feedback loop isolation
• Medical equipment demanding high safety isolation ratings
• Telecommunications infrastructure for signal integrity protection

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' confirms surface mount tape-and-reel packaging rather than standard tube delivery. Confirm that the 'X' specification designation aligns with required CTR bins if tight parameter matching is necessary. Ensure the DIP-16 footprint matches the target PCB layout dimensions. Validate that the 5300 Vrms isolation rating meets the regulatory requirements of the end application environment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a single footprint to reduce board space. Consider the 5300 Vrms isolation level for applications exceeding standard low-voltage isolation needs. Evaluate the 100 °C maximum operating temperature against ambient conditions. Compare the phototransistor output speed against system timing requirements, as these devices are not optimized for high-speed digital communication.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP817/ISP827/ISP847 series of high-density mounting phototransistor optocouplers. The series is designed to replace legacy components while offering modern surface-mount capabilities. Isocom Components positions these devices as direct replacements for common commercial optocouplers, often providing specialized parameter selection to meet specific circuit design constraints without compromising reliability or safety certifications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may exist within the same manufacturer's family, such as other variants in the ISP847 series with different lead forms or CTR specifications. Verify that any substitute maintains the 5300 Vrms isolation rating and DIP-16 package dimensions. Cross-reference safety approvals (UL/VDE) to ensure regulatory compliance remains intact.
