ISP847XDSM

Transistor, Photovoltaic Output Optoisolators Overview

The ISP847XDSM is a high-density surface-mount phototransistor optocoupler manufactured by Isocom Components. It features four independent channels within a single DIP-16 package, providing robust electrical isolation with a maximum insulation voltage of 5300 Vrms. The device utilizes an infrared LED input coupled to NPN phototransistor outputs. Key electrical parameters include a minimum collector-emitter breakdown voltage of 35 V and a maximum forward current of 50 mA. Operating temperatures range from -55°C to 100°C. The component complies with UL recognition (File No. E91231) and VDE standards.

• Power supply units needing feedback loop isolation
• Data communication interfaces for noise immunity
• Medical equipment requiring patient isolation barriers

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific Current Transfer Ratio (CTR) grade required for the application, as the 'X' suffix typically denotes a standard specification range distinct from other grades like 'C' or 'G'. Confirm that the surface-mount DIP-16 footprint matches the target PCB design. Ensure compliance with RoHS directives if applicable to the manufacturing region. Cross-reference the UL file number E91231 for final safety certification requirements in the end product.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are needed in a limited board area. The 5300 Vrms rating suits applications with high potential differences between input and output circuits. Consider the thermal management capabilities of the SMD package relative to the ambient operating temperature. Compare the CTR specifications against other variants in the ISP847 series to ensure adequate drive margins for the connected load.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP847 series of high-density optocouplers from Isocom Components. The series is designed to replace legacy through-hole components with modern surface-mount equivalents. The 'DSM' designation indicates a specific surface-mount lead form compatible with standard DIP-16 footprints. This family offers various CTR grades to accommodate different sensitivity requirements across industrial and commercial applications.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may exist within the same manufacturer's lineup, such as the ISP847CXSM or ISP847GBSM, depending on the required CTR performance. Verify that substitute parts maintain the same 5300 Vrms isolation rating and DIP-16 package dimensions. Check for equivalent safety approvals to ensure regulatory compliance in the final assembly.
